BACKGROUND
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] In general, people express several activities of their day to day life through writings. Nowadays everyone is using computing devices such as mobile phone to share their thoughts with others, despite that in many scenarios use of a pen or pencil for writing on a paper is greatly convenient. Also, a black board is being used during discussions such as office meetings, classroom sessions etc., and a combination of board and a chalk is used for expressing the ideas from many years.
[0004] Nowadays, the blackboards have been updated and replaced by the white boards, and chalks have been replaced by the marker, which are easy to use, and dust free. However, with the ease of use the user has started using a variety of markers of different colors to differentiate and/or highlight content or object written on the board. The board has limited space, and to reuse the board the user has to clean the board.
[0005] There are many cleaning devices available known as dusters to clean the boards, but sometimes we need to clean the board with a liquid to clean the content written by permanent ink, because the permanent ink cannot be erased by the duster easily. There are many liquids are available for this purpose, however, we cannot carry the liquid with us every time we attend the meeting or a session in the classroom, and it will not looks good to clean the board by applying a liquid from a separate container all the time.
[0006] There is a need to overcome above mentioned problem of stated arts by bringing a solution which facilitates in cleaning the boards efficiently. The solution provides a cleaning device that stores cleaning liquids inside the device, which is convenient to use. Also, the device that has more than one eraser to clean the block board and the white board separately.

In another exemplary embodiment, the eraser (104) can be used to clean the blackboard, and the absorbing element (110) can be used to clean the white board.
[0063] As used herein, and unless the context dictates otherwise, the term "coupled to" is intended to include both direct coupling (in which two elements that are coupled to each other contact each other) and indirect coupling (in which at least one additional element is located between the two elements). Therefore, the terms "coupled to" and "coupled with" are used synonymously. Within the context of this document terms "coupled to" and "coupled with" are also used euphemistically to mean “communicatively coupled with” over a network, where two or more devices are able to exchange data with each other over the network, possibly via one or more intermediary device.
[0064] It should be apparent to those skilled in the art that many more modifications besides those already described are possible without departing from the inventive concepts herein. The inventive subject matter, therefore, is not to be restricted except in the spirit of the appended claims. Moreover, in interpreting both the specification and the claims, all terms should be interpreted in the broadest possible manner consistent with the context. In particular, the terms “comprises” and “comprising” should be interpreted as referring to elements, components, or steps in a non-exclusive manner, indicating that the referenced elements, components, or steps may be present, or utilized, or combined with other elements, ` components, or steps that are not expressly referenced.
[0065] While the foregoing describes various embodiments of the invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof. The scope of the invention is determined by the claims that follow. The invention is not limited to the described embodiments, versions or examples, which are included to enable a person having ordinary skill in the art to make and use the invention when combined with information and knowledge available to the person having ordinary skill in the art.
