Automatic floor sweeping and mopping device

Abstract

The device of the present invention can carry out floor sweeping and mopping automatically and simultaneously. The automatic floor sweeping and mopping device includes a main body, a rotational sweeping brush unit, a dust collecting unit, two rolling wheels, a mopping unit, a water spraying unit, a squeegee unit and a water storing tank. The mopping unit is made of a soft, water-absorbing material and can remove residual dirt not removed by the rotational sweeping brush unit. The water spraying unit is an innovative feature and is provided above the mopping unit to keep the mopping unit in a clean condition by removing dusts and dirt stuck to it. The squeegee unit can squeeze dirt and dirty water out of the mopping unit and keep the mopping unit in a clean, partially wet condition. Because the device leaves no dirty water behind, such feature is surely superior.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The invention generally relates to a floor cleaning device. More particularly, the invention relates to an automatic floor cleaning device that can carry out floor sweeping (vacuuming) and mopping simultaneously. Thanks to its water spraying unit and squeegee unit, its mopping unit can be rinsed out to be kept in a clean, partially wet condition so that the device may be used to clean the floor in a continuous, efficient and easy manner.[0003]2. Description of the Prior Art[0004]As technology advances, the use of automated floor cleaning machines for floor cleaning has become quite common. In addition, such machines or robots may operate by themselves to clean the floor and thus eliminate human labor altogether.[0005]Such machines may be categorized into two types—sweeping type and mopping type. The machine of sweeping type can only get rid of regular dusts and can not eliminate finer dusts. Therefore, it needs a moppin...

Problems solved by technology

The machine of sweeping type can only get rid of regular dusts and can not eliminate finer dusts.

A disadvantage of such machine is that there is often some dirty water remaining on the floor.

Another disadvantage is that dirty water often gets into the cr
