When the tufts 211 on the cleaning roller 210 rotate to contact with the scraping strip 510, the tufts 211 are pressed to bend and deform because L1 is smaller than R, dirt scraped and dropped by the cleaning roller 210 by the scraping strip 510 can be pumped into the dirt collecting box 620 under the action of suction air flow, when the tufts 211 rotate to contact with the collision section 111, the tufts 211 slightly rebound but still are in a bending and deforming state under the action of the collision section 111 because L1 < L2 < R, and therefore the dirt adsorbed on the tufts 211 is prevented from being thrown onto the wall of the roller brush cavity 110 due to the fact that the tufts 211 rebound rapidly after being separated from the scraping strip 510. When the tufts 211 are rotated to the release section 112, as L3 is greater than R, the tufts 211 can spring back into place before contacting the surface to be cleaned, ensuring a subsequent wiping action of the tufts 211 against the surface to be cleaned.

When water needs to be sprayed during the operation of the device, the pump 720 is operated to pump the cleaning liquid in the liquid containing tank 710 to the spraying member 750, so that the cleaning liquid is sprayed to the roller brush cavity 110 from the spraying openings 756, part of the cleaning liquid washes the inclined surface 752 and then flows to the cleaning roller 210, the other part of the cleaning liquid is directly sprayed to the cleaning roller 210, and the bristles 211 on the cleaning roller 210 absorb the cleaning liquid and then are wetted, so that the wet wiping can be performed on the surface to be cleaned, and the wiping effect is improved.
