The information or intimation can be received in any readable electronic device in connection the system.Figure 14 shows a display screen of the readable electronic device thatdisplays maintenance notification by the maintenance notifier. As shown in the example of Figure 14, the present disclosure shows a script that includes a list of service time of different components. The controller compares ‘Current time = Time in script’ and when the time matches then the sms is sent to the readable electronic device.

[21] Additionally, a warm body detector (80) is provided which detects any body or object with temperature other than the prevailing surrounding temperature. Typically, the warm body detector (80) senses a warm body disposed at the cleaning surface. The warm bodies are of rat, rodent, lizards, birds (80a) and the like that generally are found in the interior of the unit such as ducts or pipeline. The presence of the warm body reduces efficiency of an HVAC system and hence if the presence is detected then cleaning of the interior of the unit can be scheduled. Further, if there are any dead rodents, birds detected then the suction unit (3) can suck the dead rodents or birds.In one embodiment, the warm body detector (80) can be a PIR sensor (80b) that senses the presence of temperature of warm bodies. The PIR sensor (80b) is connected to a processor (80c) that determines the differential temperatures and confirms whether there is warm body or not.The PIR sensor (80b) and the processor (80c) are disposed on the vehicle (1). The detected warm body isnotified to a registeredreadable electronic device (80d).

[22] In one exemplary embodiment, the at least one anti-hit and tilt sensor (82)sensesmagnetic heading, lateral angle and axial angle of the cleaning vehicle (1)and communicate to a controller that stabilizes directional movement of the vehicle (1).In one embodiment, theanti-hit and tilt sensor (82) is a micro electro-mechanical system-based accelerometer, gyrometer, magnetometer that senses magnetic heading, lateral angle and axial angle of the cleaning vehicle (1) on the cleaning surface.The sensed data are processed in the controller of the control unit and the controller signals to stabilizethe movement of the vehicle (1) and prevent from falling from a height. The sensor (82) and the controller are disposed on the vehicle (1).In an operative configuration ofthe anti-hit and tilt sensor (82), the anti-hit and tilt sensor (82) enables the vehicle (1) to operatewithout manual intervene. In an inoperative configuration of the anti-hit and tilt sensor (82), the vehicle (1) can be controlled manually by use of the control panel, joystick or any other manually operated device.

[23] In additional embodiment, the vehicle (1) has wheels (7) provided with encoders (8) that counts the number of times the wheels (7)/rotating device (not shown) attached to the wheels (7) are rotated and facilitates to determine through a control unit the distance travelled by the vehicle (1).

[24] The present disclosure describes a method for cleaning foreign particles by the robot cleaning system (100), in accordance with one embodiment of the present disclosure. The best method of performing the invention includes scrapping, by the scrapping blade (10), in contact with the cleaning surface and scrape foreign particles thereon. More specifically, the scrapping blade (10) scraps because of the movement of the vehicle (1). The scrapping blade (10)is adjustable vertically to be in contact with the cleaning surface andadjustable horizontally to adjust with the movement of the vehicle (1).

[25] The method also includes determining the difference between real-time current, of the power storage unit (4) of the cleaning equipment (2), which is sensed by the sensor (20a)with a predefined current fed in theprocessor (20b).The processor (20b) continues to allow the power storage unit (4) in the operative configuration and continue cleaning in event when the value of the current received from the sensor (20a) is less than the predefined current value.The processor (20b) stopsthe power storage unit (4)and thereby stops cleaning in event when the value of the current received from the sensor (20a) is equal to or more than the predefined current value till the processor (20b) determines that the value of the current received from the sensor (20a) is less that the predefined current.

[26] The method still includes sterilizing by at least one:
o emitting light from the ultraviolet light emitting source (30a) disposed on the vehicle (1); and
o emitting ozone gas from the ozone generator (30b) disposed on the surface and is defined with the outlet (30c), the outlet (30c)is connected to one end of the ozone pipe (30d) and other end connected to the vehicle (1) and delivers ozone gas to sterilize area surrounding the vehicle (1).

[27] The method also includes switching between thepower supplied by thepower storage unit (4) and a power socket and hence provides back power.In event when the power storage unit (4) is drained then the power socket is connected to theelectric power supply circuit through theswitched-mode power supply(40c) and plugging the plug-in pin (40b)to the electric power supply circuitand facilitate operation of the vehicle (1). More specifically, the plug-in port (40a), provided at the electric power supply circuit, is connected to the at least one plug-in pin (40b). The plug-in pin is connected to the switched-mode power supply (40c). The switched-mode power supply (40c) is connected to the power socket by the wire connection (40d). Thus, in event when the power storage unit (4) is drained, the vehicle (1) can continue the operation without the need to wait for the power storage unit (4) to be recharged or replaced by connecting to the power socket.

[28] The method further includes sensing, by the at least one sensor (50a) of the real-time cleaning efficiency monitoring unit (50) positioned on the vehicle (1), particulate matter in the region of the vehicle (1) and processing, in the at least one processor (50b), sensed particulate matter into a readable data readable on a readable electronic device and derive the cleaning efficiency based on the sensed particulate matter and predefined particulate matter fed in the processor (20b). Thus, the real-time cleaning efficiency monitoring unit (50) provides the cleaning efficiency/performance in real-time and enables to decide whether further cleaning is required.

[29] The method still includes indicating failure, by the failure indicator, of the operational components by sensing input current. The values of the input current at the operational components/devicesare measured by the current sensor/ammeter are displayed on the readable electronic devices.

[30] The method also includes notifying, by the maintenance notifier, maintenance requirement of the at least one cleaning equipment unit (2), the suction unit (3) and the scrapper blade (10) by comparing, in the controller, maintenance database with real-time date, wherein the maintenance database includes maintenance schedule. The information or intimation can be received in any readable electronic device in connection the system (100).

[31] In one embodiment, the method includes determining presence of the warm body, disposed at the cleaning surface, by the warm body detector (80) that senses the sensor and notifies the sensed warm body to any readable electronic device (80d).
