Description:FIELD OF THE INVENTION

[0001] The present invention relates to an automated hygiene maintenance device for high-traffic areas that is capable of continuously maintaining cleanliness in high-traffic areas by detecting and removing contaminants, ensuring the environment remains safe, hygienic, and suitable for public use.

BACKGROUND OF THE INVENTION

[0002] In public and high-traffic areas such as offices, hospitals, shopping complexes, airports, schools, and railway stations, cleanliness and hygiene play an important role in maintaining public health and comfort. Floors and surfaces in such places are frequently exposed to dust, debris, liquid spills, and other contaminants due to heavy movement of people. Continuous cleaning and maintenance is required to ensure that the environment remains safe, hygienic, and free from unpleasant odors. The need for effective, timely, and reliable cleaning solutions is therefore critical in such areas.

[0003] Traditionally, the cleaning and hygiene of such places are carried out manually using tools like brooms, mops, buckets, brushes, and vacuum cleaners. In some cases, semi-automatic floor cleaning machines or sweepers are used, but these also require continuous human operation and supervision. Manual cleaning methods are labor-intensive, time-consuming, and often inconsistent in effectiveness, especially in areas with large crowds. Additionally, manual cleaning may not immediately address spills, odor formation, or fine debris, resulting in delayed maintenance.

[0004] These traditional methods also face drawbacks in terms of efficiency and long-term hygiene maintenance. Human error, irregular cleaning intervals, and the inability to detect or clean microscopic contaminants reduce the effectiveness of manual cleaning. Further, manual methods cannot easily provide real-time monitoring of cleanliness levels or environmental conditions such as humidity, temperature, and air quality. This lack of timely intervention can result in unhygienic conditions, spread of infection, and discomfort to users in crowded spaces.

[0005] US6883201B2 discloses about an autonomous floor-cleaning robot comprises a self-adjusting cleaning head subsystem that includes a dual-stage brush assembly having counter-rotating, asymmetric brushes and an adjacent, but independent, vacuum assembly such that the cleaning capability and efficiency of the self-adjustable cleaning head subsystem is optimized while concomitantly minimizing the power requirements thereof. The autonomous floor-cleaning robot further includes a side brush assembly for directing particulates outside the envelope of the robot into the self-adjusting cleaning head subsystem.

[0006] US20220007912A1 discloses about a surface cleaner is disclosed having a base moveable along a surface and an operating component configured to perform a function of the cleaner. The surface cleaner includes a sensor configured to generate a signal based on the surface and a controller in communication with the sensor and the operating component. The controller is operable to convert the signal from a time domain to a frequency domain to generate a surface fingerprint. Furthermore, the controller is operable to control the operating component based on the surface fingerprint.

[0007] Conventionally, many devices are available for maintaining hygiene in traffic areas. However, the cited invention exhibits certain limitation in terms of adaptability, scope of cleaning, and overall effectiveness in maintaining consistent hygiene. They are primarily designed for specific cleaning functions and do not adequately address the broader requirements of real-time monitoring, timely intervention, and long-term maintenance in crowded environments.

[0008] In order to overcome the aforementioned drawbacks, there exists a need in the art to develop a device that is capable of providing comprehensive hygiene management in high-traffic areas. The device should ensure continuous cleanliness, allow real-time monitoring of hygiene conditions, enable timely response to contaminants, and maintain long-term effectiveness, thereby improving overall safety, health, and comfort for users.

[0023] The present invention relates to an automated hygiene maintenance device for high-traffic areas that is capable of facilitating real-time monitoring of environmental conditions, enabling timely cleaning and preventing the buildup of dirt or microbial growth, thus maintaining overall efficiency in managing hygiene in high-traffic environments.

[0024] Referring to Figure 1, an isometric view of an automated hygiene maintenance device for high-traffic areas is illustrated comprising of a platform 101, a plurality of openings 102 arranged on the platform 101, each opening integrated with a dust extraction assembly 103 includes a motorized iris operated lid 103a, a vibrating unit 103b integrated within the platform 101, a suction unit 103c integrated within a secondary compartment of the lower layer, a brush assembly 104 slid ably installed along edges of the platform 101 via a motorized guiding rail 104a, includes a motorized brush 104b installed on an articulated linkage 104c via a motorized ball and socket joint 104d, a hitting unit 105 vertically installed on the platform 101 includes a pole 105a, a motorized slider 105b and a tapping bar 105c, a liquid dispensing arrangement 106 installed on the platform 101 includes a multi-sectioned vessel 106a is equipped with an electronic sprayer 106b, a holographic projection unit 107 is installed on the platform 101, a hair or fibers removal module 108 arranged on the platform 101, includes a motorized roller 108a laid with multiple extendable U-shaped pins 108b, the roller 108a is mounted on an articulated arm 108c.

[0025] The device disclosed herein comprises of the platform 101 that includes the upper layer and the lower layer. The upper layer is made from durable materials capable of withstanding continuous foot traffic without deformation or wear, while the lower layer houses multiple compartments configured to accommodate operational components required for the functioning of the device.

[0026] The upper layer of the platform 101 mentioned herein is constructed from durable, high-strength materials that are capable of withstanding continuous foot traffic in high-traffic areas. The surface is designed to resist scratches, pressure, and wear caused by frequent usage while maintaining a smooth and stable walking experience. The layer incorporates anti-slip characteristics to ensure safety for users moving across it. The upper layer is resistant to moisture and easy to clean, thereby ensuring long-term hygiene and reliability. The structural design allows uniform load distribution, preventing deformation or damage under heavy use.

[0027] In an embodiment of the present invention the upper layer of the platform 101 is formed using composite laminates reinforced with polymer coatings that provide both strength and resilience against abrasion. The surface is textured with micro-patterns that enhance grip while allowing controlled redirection of liquids to peripheral edges, preventing pooling in the central region. The material composition includes anti-microbial additives that inhibit bacterial growth on the walking surface. The upper layer further incorporates shock-absorbing properties that minimize noise and vibration generated during continuous use in crowded areas.

[0028] The lower layer of the platform 101 is designed as a supporting structure that houses multiple compartments within its body. The lower layer of the platform 101 is made from strong, load-bearing materials that provide stability and balance to the entire platform 101 during use. The compartments within the lower layer are arranged in an organized manner to enable efficient allocation of internal space while maintaining structural strength. The lower layer is engineered to withstand static and dynamic stresses caused by frequent human activity on the upper layer.

[0029] In an embodiment of the present invention the lower layer of the platform 101 is constructed as a reinforced base made from high-strength alloys combined with polymer composites to provide rigidity and impact resistance. The layer is designed with thermally insulated walls that protect internal compartments from temperature fluctuations and external moisture. Structural ribs are incorporated within the base to evenly distribute load stresses and maintain platform 101 stability. The interior arrangement of the lower layer allows modular compartmentalization, enabling easy installation or replacement of enclosed units.

[0030] The device is equipped with a sensor array arranged on the platform 101 for detecting various environmental and surface parameters. The sensor array comprises a dust detection sensor for identifying particulate accumulation. The dust detection sensor operates by emitting a focused beam of light across the surface and measuring the scattering effect produced when airborne or surface dust particles pass through the beam. The intensity and angle of the scattered light are detected by a photodiode, which converts the light into electrical signals. These signals are then analyzed to determine the density and concentration of particulate matter on or near the platform 101 surface.

[0031] For an example, in a busy airport terminal, the dust detection sensor integrated into the device continuously monitors the platform 101 surface as thousands of passengers pass by. When small particles from shoes, luggage wheels, or ambient air settle on the platform 101, the sensor detects the scattering of the emitted light beam and signals the controller about increased dust concentration.

[0032] A VOC (volatile organic compound) sensor for detecting odor-causing elements. The VOC sensor functions by drawing in air samples from the surrounding environment and exposing them to a gas-sensitive semiconductor layer, typically metal oxide. When volatile organic compounds are present, they react with the sensor’s surface, altering its resistance. This change in resistance is processed as an electrical signal proportional to the concentration of VOCs in the air.

[0033] For an example, in a hospital waiting area, the VOC sensor integrated into the device detects odor-causing compounds released from spilled disinfectants, cleaning agents, or even body odors in a crowded environment. As the air sample passes through the sensor, the rise in VOC concentration alters its resistance, which is processed into an alert signal. Based on this detection, the device neutralizes the odor and maintaining a fresh, hygienic environment without requiring manual monitoring.

[0034] A temperature sensor for monitoring ambient temperature, the temperature sensor is implemented using a thermistor, a semiconductor device with resistance that varies predictably with temperature changes. As ambient temperature fluctuates, the resistance of the thermistor increases or decreases accordingly. The sensor circuit measures this resistance change and converts it into a digital signal, which is processed by the microcontroller to provide accurate real-time temperature readings. This measurement allows continuous monitoring of environmental conditions, ensuring that the device operates within safe thermal limits.

[0035] For an example, in a shopping mall corridor, the temperature sensor embedded in the device continuously tracks changes in ambient temperature caused by air conditioning cycles and fluctuating crowd density. When the thermistor detects a rise in temperature beyond preset limits, the resistance variation is converted into a digital signal and analyzed by the microcontroller. Based on this data, the device adjusts cleaning cycles and activates disinfectant spraying more frequently, ensuring that higher temperatures do not compromise hygiene or surface safety.

[0036] A humidity sensor for assessing moisture content in the environment. The humidity sensor operates on a capacitive principle, using a hygroscopic polymer film placed between two conductive electrodes. When atmospheric moisture is absorbed into the polymer layer, its dielectric constant changes, causing a measurable variation in capacitance. This change is converted into an electrical signal proportional to relative humidity levels. The sensor continuously transmits data to the device controller, providing real-time monitoring of environmental moisture conditions. Accurate humidity measurement is critical for preventing condensation or microbial growth on the platform 101, and the sensor ensures automated adjustment of cleaning or drying functions when humidity exceeds defined operational thresholds.

[0037] For an example, in a hospital waiting area, the humidity sensor monitors atmospheric moisture levels that fluctuate due to frequent door openings and patient occupancy. When the hygroscopic polymer film absorbs excess moisture, the resulting capacitance change signals rising humidity levels. The microcontroller interprets this data and automatically activates drying or disinfectant spraying cycles to prevent condensation and microbial growth on the platform 101 surface.

[0038] A moisture sensor for detecting liquid presence, and an optical sensor for identifying contaminants such as hair and fibers on the platform 101 surface. The moisture sensor mentioned herein uses a resistive sensing method with two conductive probes embedded on the platform 101 surface. In the absence of liquid, the electrical resistance between the probes remains high. When liquid is present, it bridges the probes and reduces resistance significantly. This resistance change is measured and converted into a signal confirming liquid presence and concentration. The moisture sensor provides real-time detection of spills, leaks, or residual cleaning fluids on the platform 101.

[0039] For an example, in an airport lounge, the moisture sensor detects an accidental coffee spill on the platform 101 surface. The liquid bridges the conductive probes, reducing resistance and generating a signal that immediately alerts the device controller. This prevents passengers from slipping, eliminates sticky residues, and ensures continuous cleanliness, demonstrating the sensor’s role in maintaining both safety and hygiene in busy public environments. The data captured by the sensor array is processed by the microcontroller for initiating appropriate cleaning or maintenance actions.

[0040] The plurality of openings 102 is arranged on the platform 101, and each opening is integrated with the dust extraction assembly 103. The dust extraction assembly 103 includes the motorized iris-operated lid 103a that opens and closes based on real-time contamination data received from the sensor array, thereby exposing or sealing the opening as required. The iris lid 103a mentioned herein is an adjusting circular aperture comprised of an actuation ring and a plurality of blades according to the size of the lid 103a.

[0041] The blades are engraved with the protrusions through which the actuation ring is affixed to each blade. The actuation ring is connected to a motor, which helps in the movement of the actuation ring leading to the movement of blades inward or outward to change the size of the opening. When the blades close, the aperture becomes smaller, closing the lid 103a. When the blades open, the aperture widens, opening the lid 103a. This adjustment allows the iris lid 103a for exposing or sealing the opening as required.

[0042] The vibrating unit 103b is integrated within the platform 101 to generate vibrational sensations that loosen embedded debris from the upper layer, facilitating efficient removal. vibrating unit 103b based on an eccentric rotating mass (ERM) motor functions by utilizing a small unbalanced weight attached to the shaft of a compact electric motor. When electrical power is supplied, the motor rotates the shaft along with the off-center weight. This rotation creates an uneven centrifugal force, which generates mechanical vibrations. The frequency and intensity of the vibration can be controlled by adjusting the motor’s speed and voltage. These vibrations are transmitted to the platform 101 surface, effectively loosening embedded dust, dirt, or fine particles.

[0043] The suction unit 103c is integrated within a secondary compartment of the lower layer and connected with the openings 102 for extracting loosened debris and contaminants into the secondary compartment for safe storage and later disposal. suction unit 103c works by creating a negative pressure differential that draws in air and debris through connected openings 102. The suction unit 103c mentioned herein typically employs a motor-driven impeller or fan that rapidly rotates, reducing air pressure inside the suction chamber. This pressure difference forces surrounding higher-pressure air to flow into the openings 102, carrying dust, dirt, and contaminants along with it. The incoming air-debris mixture passes through ducts into the secondary compartment, where filters or separators trap solid particles while allowing clean air to be expelled.

[0044] The device further comprises the brush assembly 104 slid ably installed along the edges of the platform 101 through the motorized guiding rail 104a. The brush assembly 104 includes the motorized brush 104b mounted on the articulated linkage 104c via the motorized ball and socket joint 104d. The motorized guiding rail 104a operates by integrating a linear actuator or motor-driven belt that facilitates controlled movement of the brush assembly 104 along the edges of the platform 101. When powered, the motor drives the belt or lead screw, translating rotary motion into precise linear displacement of the mounted brush 104b. This allows the brush 104b to move along the entire perimeter, maintaining consistent contact with the surface. The controlled motion enables efficient cleaning, ensures uniform coverage, and assists in systematic debris collection along the platform 101 edges.

[0045] The motorized brush 104b is driven by an electric motor that rotates a cylindrical or disc-shaped brush 104b fitted with bristles. The motor imparts torque to the brush 104b, enabling it to sweep and dislodge debris from the platform 101 surface. Rotation speed is controlled to adjust cleaning intensity according to surface conditions. The brush 104b bristles penetrate and loosen dirt, dust, and fibers, channeling them toward collection openings 102. Continuous motor operation ensures consistent rotation, providing uniform debris removal. The motorized brush 104b converts electrical energy into mechanical motion, generating sweeping action that effectively removes particles from the surface in real time.

[0046] The articulated linkage 104c comprises interconnected pivot joints that allow controlled multi-axis movement of the brush 104b relative to the platform 101. Actuators or motors drive the linkage 104c to extend, retract, tilt, or adjust the brush 104b angle during operation. Joint positions are monitored using position sensors for precise control. The linkage 104c ensures that the brush 104b maintains optimal contact with the platform 101 surface while following contours or edges. The controlled articulation enables adaptive brush 104b movement in response to surface variations, providing consistent cleaning coverage.

[0047] The motorized ball and socket joint 104d allows for smooth, adjustable movement in various directions. It has a ball-shaped part that fits into a cup-like socket. A motor controls this ball, making it move around inside the socket. Actuators adjust the ball’s position to ensure it moves accurately and flexibly, enabling precise control and positioning in multiple directions providing consistent cleaning coverage. This allows the motorized brush 104b to pivot and extend over the surface of the upper layer for cleaning, sweeping, and pushing contaminants into a sliding dust collection tray that is arranged within a primary compartment of the lower layer. The brush assembly 104 retract when not in use, ensuring compact storage within the platform 101.

[0048] For the removal of stubborn contaminants, the device is provided with the hitting unit 105 vertically installed on the platform 101. The hitting unit 105 includes the pole 105a, the motorized slider 105b, and the tapping bar 105c. The pole 105a serves as the vertical support and guiding structure for the hitting unit 105. The hitting unit 105 provides a stable track along which the motorized slider 105b can move, ensuring controlled linear motion. The pole 105a is constructed from rigid materials to withstand repeated mechanical impacts without bending or deformation. The surface is designed to minimize friction with the slider 105b, enabling smooth vertical movement. By maintaining alignment and stability, the pole 105a ensures that the tapping bar 105c strikes the platform 101 surface accurately and consistently, allowing efficient dislodging of stubborn dirt and contaminants during operation.

[0049] Based on the data received from the sensor array, the microcontroller activates the slider 105b to deploy the tapping bar 105c at targeted spots on the upper layer to dislodge dirt, stains, or other debris that is difficult to remove through regular cleaning. The motorized slider 105b is a mechanically driven assembly designed to move the tapping vertically along the pole 105a. The slider 105b consists of an electric motor coupled with a lead screw or belt drive, which converts rotational motion into precise linear displacement. When powered, the slider 105b raises or lowers the tapping bar105c along the pole 105a with controlled speed, stroke length, and force. This controlled movement ensures that the tapping bar 105c impacts specific areas accurately, loosening stubborn dirt and contaminants from the platform 101 surface.

[0050] The device also includes a liquid dispensing arrangement 106 mounted on the platform 101 for disinfection and odor management. The liquid dispensing arrangement 106 incorporates the multi-sectioned vessel 106a storing different types of liquids such as antimicrobial solutions, disinfectants, and aromatic sprays.

[0051] Each section of the vessel 106a is equipped with the electronic sprayer 106b that is activated based on the environmental data from the sensor array to release appropriate liquid sprays on or around the upper layer to neutralize foul odors and maintain hygiene.

[0052] The electronic sprayer 106b mentioned herein atomizes and dispenses liquid from the vessel 106a onto the upper layer or surrounding area. When powered, the sprayer 106b generates a fine mist or spray pattern, distributing the liquid evenly across the targeted surface. The spray intensity, duration, and frequency are controlled electronically to match the requirements determined by environmental conditions. The sprayer 106b operates with rapid response, allowing immediate release of disinfectants, aromatic liquids, or other solutions. The precise operation ensures optimal coverage, neutralization of odors, and maintenance of hygiene without over-saturating the surface or causing spillage.

[0053] The hair and fibers removal module 108 is also arranged on the platform 101 for managing clogging and hygiene issues caused by such contaminants. The module includes the motorized roller 108a embedded with multiple extendable U-shaped pins 108b. The roller 108a is mounted on the articulated arm 108c that operates in response to detected hair or fiber on the upper layer.

[0054] The motorized roller 108a is a cylindrical component driven by an electric motor, enabling continuous rotation along the platform 101 surface. The motor imparts controlled rotational motion, with adjustable speed to maintain optimal torque and surface engagement. The roller’s rotation generates frictional and sweeping action over the surface, allowing it to interact with debris or loose particles. The motor ensures uniform and consistent motion, maintaining steady rotational force across the roller’s length. Continuous rotation enables the roller 108a to operate efficiently over the platform 101, providing consistent movement and coverage, supporting cleaning or surface-contact functions without external intervention.

[0055] The articulated arm 108c connects the motorized roller 108a to the platform 101 and provides multi-axis movement. The articulated arm 108c allows the roller 108a to pivot, tilt, or adjust its position dynamically across the upper layer. The articulated arm 108c operates mechanically in response to roller 108a rotation and contaminant engagement, ensuring optimal contact with the surface. The joints provide flexibility to navigate uneven surfaces, edges, or corners while maintaining consistent pressure.

[0056] As the roller 108a passes over the platform 101 surface, the pins 108b extend to collect and remove hair and fibers, thereby preventing clogging and ensuring consistent cleanliness. The U-shaped pins 108b mentioned herein is powered by a pneumatic unit that embodies an air compressor, air cylinder, air valves, and piston which work in collaboration to perform the extension and retraction of the U-shaped pins 108b. The U-shaped pins 108b comprises a nested tube arrangement that contains multiple hollow tubes connected concentrically.

[0057] The air cylinder is attached to the bottom of the nested tube arrangement and further consists of an air piston attached to the topmost part of the nested tube arrangement from the inside. The air cylinder is integrated with one inlet and one outlet valve that is connected to an air compressor. The air compressor draws air from the surroundings and compresses it to form pressurized air which enters the inlet valve and creates a force that pushes the piston in the forward direction. As the piston moves in the forward direction, it leads to the sequential opening of the concentrically connected tubes from the top toward the bottom. This leads to the extension of the U-shaped pins 108b to collect and remove hair and fibers, thereby preventing clogging and ensuring consistent cleanliness.

[0058] The device further comprises a liquid absorption module installed on the platform 101 for managing spills. The liquid absorption module includes a micro vacuum pump that extracts detected spilled liquid through ducts and channels it into a sealed reservoir located within the lower layer of the platform 101. The micro vacuum pump operates by creating a pressure differential that draws liquid into the suction. An electric motor drives an impeller or diaphragm, reducing pressure within the pump chamber relative to the surrounding environment. This negative pressure forces liquid from the surface or ducts into the pump inlet.

[0059] The pump maintains a continuous flow, ensuring that spilled liquid is actively drawn from the platform 101 surface. The pump compact design allows integration within the module, providing sufficient suction force to move liquids efficiently through the flow while preventing backflow or leakage during operation. This arrangement ensures that liquid spills are managed immediately without affecting the functionality of the platform 101 or creating unsafe conditions for users.

[0060] For user interaction and notifications, the device is integrated with a holographic projection unit 107 installed on the platform 101. The holographic projection unit 107 is configured to project spatial visuals, including alerts, diagnostics, and operational updates, thereby providing a contactless interface for users or maintenance personnel. The holographic projection unit 107 operates by generating three-dimensional visual images through the controlled interference of light beams.

[0061] A light source, typically a laser or LED, emits coherent light that is directed through beam splitters and spatial light modulators to form holographic patterns. These patterns are projected into free space above the platform 101, creating visible spatial visuals without requiring a physical screen. The unit receives digital signals from the controller, which encodes alerts, diagnostics, or operational data into modulated light patterns. The projection continuously updates in real time, providing a contactless visual interface for monitoring, user notifications, and maintenance guidance

[0062] The device is centrally controlled by the microcontroller integrated with a communication module. The communication module establishes a wireless connection with an external computing unit featuring a user interface for remote monitoring. The user interface displays real-time information including device status, environmental data, maintenance alerts, and cleaning cycle history. The data is transmitted to a connected database in real time, enabling records of hygiene conditions and ensuring continuous tracking of cleaning operations.

[0063] The microcontroller activates the inbuilt communication module for
establishing a wireless connection between the microcontroller and the computing
unit that is inbuilt with the user-interface and accessed by the user for enabling records of hygiene conditions and ensuring continuous tracking of cleaning operations. The user interacts with the interface through a touch screen, keyboard, or other input methods available on the computing unit. The computing unit mentioned herein includes, but not limited to smartphone, laptop, tablet.

[0064] The database functions as a centralized digital storage for all operational, environmental, and maintenance data collected by the device. The database receives real-time data from the microcontroller, including cleaning cycle history, platform 101 status, environmental measurements, and maintenance alerts. The database is implemented as a relational or cloud-based structured database, allowing efficient organization, indexing, and retrieval of large datasets. Data entries are timestamped and stored in tables with defined relationships, enabling historical analysis and trend monitoring. Secure access protocols ensure data integrity and prevent unauthorized modifications, while continuous updates facilitate real-time tracking, reporting, and analysis of hygiene and operational performance.

[0065] The communication module mentioned herein includes, but not limited to Wi-Fi (Wireless Fidelity) module, Bluetooth module, GSM (Global System for Mobile Communication) module. The communication module used in the device is preferably the Wi-Fi module. The Wi-Fi module enables wireless communication by transmitting and receiving data over radio frequencies using IEEE 802.11 protocols. It connects to a network via an access point, converting digital data into radio signals. The module processes TCP/IP protocols for data
exchange, interfaces with microcontrollers through UART/SPI, and ensures
encrypted communication using WPA/WPA2 security standards for secure and
efficient wireless connectivity.

[0066] The present invention works best in the following manner, where the device includes platform 101 configured with an upper layer made from durable materials capable of withstanding foot traffic and the lower layer housing multiple compartments operates by first utilizing the sensor array arranged on the platform 101 to detect contaminants, debris, liquid spills, environmental temperature, humidity, and presence of hair or fibers on the upper layer. Upon detection of dust or particulate matter, the dust extraction assembly 103 is activated, the motorized iris operated lid 103a opens the openings 102, and the vibrating unit 103b generates vibrational sensations to loosen embedded debris. The suction unit 103c then draws the loosened debris into the secondary compartment of the lower layer for safe collection. Simultaneously, the brush assembly 104 moves along the motorized guiding rail 104a, with the motorized brush 104b pivoting and extending over the upper layer via the articulated linkage 104c and motorized ball and socket joint 104d, sweeping debris toward the dust collection tray within the primary compartment.

[0067] In continuation with for stubborn contaminants, the hitting unit 105, comprising the pole 105a, motorized slider 105b, and tapping bar 105c, is deployed to apply targeted mechanical force, dislodging adhered dirt from the platform 101 surface. Detected spills are managed by the liquid absorption module, where the micro vacuum pump extracts liquid through ducts into the sealed reservoir within the lower layer. The aromatic liquid dispensing module selectively releases anti-microbial, disinfectant, or aromatic sprays from the multi-sectioned vessel 106a using electronic sprayer 106b, based on real-time environmental data. Hair and fibers on the upper layer are removed by the motorized roller 108a mounted on the articulated arm 108c, which operates in response to detected contaminants, preventing clogging. The holographic projection unit 107 provides spatial visuals, delivering notifications and operational diagnostics. The microcontroller communicates with the remote computing unit via the wireless communication module, transmitting status, maintenance alerts, and cleaning cycle data to the database in real time.
