A floor-cleaning appliance has a housing movable in a working direction, forming a chamber, and having a downwardly directed intake opening extending in the working direction and in a transverse direction crosswise thereto. A front deflector and a rear deflector are provided in the opening with the latter spaced rearward in the working direction from the former. A flexible cleaning element is spanned over the deflectors and engageable with a floor surface below the housing.

A cleaning device is provided. The cleaning device includes a driving roller, a driven roller, a flexible cleaning belt sleeved on the driving roller and the driven roller, a garbage collection box disposed on one side of the cleaning belt, a brush disposed over the garbage collection box, a sewage collection tank, a clean water tank and a water squeezing roller disposed on the side of the cleaning belt. The garbage collection box is provided with a guide plate near one end of the cleaning belt, and the guide plate corresponds to the outer side of the cleaning belt. The sewage collection tank and the clean water tank are located downstream of the garbage collection box along the moving direction of the cleaning belt, and the water squeezing roller corresponds to the sewage collection tank.

A multi-purpose cleaning appliance avoids the need for separate appliances for vacuuming and mopping, and includes a floor tool body including a base and wheels for supporting the floor tool body on a floor with the base above the floor; and a mopping module and a vacuum cleaner module that are interchangeably mountable to the floor tool body for mopping or vacuuming the floor respectively, with the mopping module configured to perform wet mopping.

A floor mopping machine includes a casing and a motor. A partition plate is arranged at a middle of the casing, and a battery is arranged at a side of the partition plate. A first support roller is provided at an end of the battery away from the motor, and a second support roller is provided at an end of the first support roller away from the battery. A set of second pressure rollers are arranged between the first support roller and the second support roller, and a set of third pressure rollers are arranged between the first support roller and a driving roller.

A remote access duster with a body, a flexible duster cord loop that is configured to be propelled such that part of the loop moves outward from the body while another part moves inward toward the body, and a vacuum source that is configured to draw air over the cord.

The disclosure relates to a cleaning device comprising a driving roller, a driven roller, a flexible cleaning belt sleeved on the driving roller and the driven roller, a garbage collection box, a brush, a sewage collection tank, a clean water tank and a water squeezing roller. The garbage collection box is provided with a guide plate near one end of the cleaning belt. The sewage collection tank and the clean water tank are located downstream of the garbage collection box along the moving direction of the cleaning belt. The cleaning device is provided with a sewage collection tank and a clean water tank. Clean fluid in the clean water tank flows onto the cleaning belt to clean the cleaning belt, and the sewage water and excess water on the cleaning belt are squeezed into the sewage collection tank by the water squeezing roller.

Disclosed is a floor cleaning device, including a water tank; a cleaning cloth wrapped around the water tank; a plurality of support shafts and a plurality of transmission shafts which are respectively provided in the water tank to support the cleaning cloth; a driving mechanism connected to the transmission shafts to drive the cleaning cloth to move circularly in the water tank; and a cleaning mechanism provided above the cleaning cloth to remove dirts on the surface of the cleaning cloth. The disclosure achieves a self cleaning at the same time of the floor cleaning, so that there is no need for the user to wash the used cleaning cloth or change a disposable cloth after the floor cleaning, realizing a true cleaning without producing the secondary pollution.

An infinity brush has a flaccid belt configured to define a lemniscate. A plurality of work-contacting segments protrude from and are carried by the flaccid belt. A mechanical drive rotates the flaccid belt. Various embodiments of the flaccid belt include a single lemniscate, a plurality of lemniscates, and various simulated lemniscates. In one embodiment, the infinity brush bristle includes non-cylindrical brush bristles with a longitudinal shaft having at least one diameter transition, while other bristles comprise beads of various oval, circular, and cylindrical geometries.

A sweeping robot includes: a robot body; and a rag box detachably connected to the robot body. The rag box includes: a box body; two rag rolls detachably connected to the box body. The two rag rolls include a first rag roll and a second rag roll; and a rag having one end wound around the first rag roll, and the other end wound around the second rag roll, after the rag is gradually released from the first rag roll, the rag is wound around the second rag roll.

A method of cleaning a surface includes steps of (1) positioning a brush in contact with the surface; (2) rotating the brush relative to a drum about a second axis; and (3) rotating the drum relative to a bracket, supporting the drum, about a first axis, parallel to the second axis, such that the brush orbitally revolves about the first axis.
