The cleaner is a very conventional floor cleaning tool, but the cleaner is very noisy and uncomfortable. And the cleaning mode of the garbage is just to suck the garbage into the garbage box.

Broom, mop, floor brush are of the type of cleaning tools that generally have a fixed cleaning section with a cleaning capacity that is determined by the dirt removal and suction capacity of the cleaning section. Since the cleaning portion is contaminated upon contact with the soiled floor, the cleaning ability is gradually reduced during the subsequent cleaning process, and particularly when the cleaning is continuously performed over a large area, thorough cleaning is not possible. Therefore, the cleaning products must be rinsed frequently, which is very troublesome.

For Chinese consumers, the sweeping and mopping are necessary, and the thorough cleaning of the floor can not be realized only by sweeping or mopping. However, these existing mopping machines require either constant washing or a complex structure, which is costly and prohibitive for the average consumer.

Moreover, existing floor cleaning tools can either only clean dry waste (brooms or cleaners, etc.), or can only be used to clean liquid waste (mops, floor wipes, etc.). It is either particularly poor or laborious (e.g. rag, need to be washed several times) for cleaning dry and wet mixed waste, especially sticky waste (e.g. syrup, tomato paste, etc.), so to speak.
