On the opposite side, i.e. in the region B on the lower right side of the roll brush 5 as shown in the drawing, it is possible to provide a smaller gap between the floor-washing roll brush 5 and the peripheral shield 8 so that the suction air does not easily pass therethrough, thereby ensuring that the region a has sufficient suction wind force for assisting suction and entrainment of the sewage into the sewage recovery channel 42.

The utility model discloses an in the normal course of operation of intelligence scrubber of an exemplary embodiment, lead clear water tank 3's clear water to rolling brush 5 and spill water and wet, the rolling brush part that is moistened rolls and clean (with the help of scrub and/or scrubbing effect) ground, then rolls and gets back to near sewage recovery mouth 41, this moment this rolling brush part wash the sewage behind the ground can be thrown away with the help of centrifugal action, the negative pressure air current that fan 2 effect produced simultaneously can bring the water of throwing away (together with subaerial filth, if have) into sewage recovery passageway 42 and get into in filth case 4. In this regard, the utility model discloses an intelligence scrubber not only can play the effect of washing ground and retrieving sewage, still can play the solid filth of dust absorption/suction part simultaneously in order to realize the clear effect in ground.

In order to prevent moisture and other dirt from entering the fan 2 and affecting the normal operation of the fan 2 as much as possible, a water baffle 22 may be additionally arranged between the fan airflow channel 21 communicating the fan 2 and the dirt box 4, and the water baffle 22 may be arranged on one side of the fan airflow channel 21 close to the dirt box 4. Further, according to an example, a water absorbing sponge 23 may be provided at an end of the fan airflow passage 21 near the water guard 22. Of course, it is well understood and realized by those skilled in the art that other types of air filtration devices, such as appropriately sized filter cartridges, screens, etc., may be provided in place of or in addition to the water absorbent sponge 23.
