A cleaning device comprises a handle (14) and a cleaning head (12) which is movable on a surface to be cleaned, wherein said cleaning head (12) comprises at least one rotatable cleaning roller (16, 18) and a first lip element (22) arranged adjacent to a first suction gutter (32) which can be subjected to negative pressure by means of a suction pump (44), and said cleaning head (12) comprises a second lip element (24) arranged adjacent to a second suction gutter (32) which can be subjected to negative pressure by means of the suction pump (44). The first lip element (22) and the second lip element (24) are each movable between a raised position and a lowered position, and the handle (14) is pivotable such that in a first position of said handle (14) relative to the cleaning head (12), the first lip element (22) is in the lowered position and the second lip element (24) is in the raised position, and in the second position of said handle (14) relative to the cleaning head (12), the first lip element (22) is in the raised position and the second lip element (24) is in the lowered position.

A surface cleaning apparatus such as an extractor has a fluid flow path extending from a dirty fluid inlet head to a clean air outlet. The fluid flow path upstream of the separation stage comprises a removable portion.

An extraction cleaner includes a portable extractor and a base adapted to be moved to perform a cleaning operation on a floor surface when the portable extractor is operably mounted to the base. The portable extractor includes a recovery tank assembly provided on the housing adjacent to the recovery tank assembly.

A surface cleaning apparatus has a fluid distribution system for storing and delivering fluid to a surface to be cleaned, and includes a steam nozzle in fluid communication with a steam generator. A pad mounting plate is adapted to mount a cleaning pad to the apparatus, and has a steam orifice in fluid communication with the steam nozzle. A flexible seal is provided between the steam nozzle and the pad mounting plate to seals a space between the steam nozzle and the steam orifice to prevent steam leaks.

The present invention provides an autonomous cleaning robot device for cleaning in the animal husbandry environment. The cleaning robot is composed of a master machine (autonomous moving controller) and a slave machine (self-propelled cleaning head). The master machine and the slave machine are connected by a robotic arm and a traction hose. The robotic arm can adapt to the movement of the cleaning slave machine to reduce the resistance and secondary pollution or damage caused by friction between the traction cable and the ground during the movement. The traction hose combined with the robotic arm allows slave machine to enter and exit the fence without opening and closing the door to improve efficiency. In the treatment of dirt, the excrement is collected by a suction driving device, and is centrally collected in a storage tank, and then is compacted into blocks by the excrement compression device.

The present disclosure relates generally to an apparatus for cleaning or otherwise treating a floor or ground surface. Devices provided herein include various features to enhance the efficiency and efficacy of cleaning operations. Such devices includes, but are not limited to, bearing protector devices, cord and cable management devices, and ergonomic features useful with ride-on floor treating machines.

The improved mobile robot utilizes a cooperative wheeled support arrangement having a unique axle design that preferably cooperates with a base support module. A tri-axle is preferably used to support at least one omni-wheel on each axle section. Multiple omni-wheels on each section can be used for higher load applications. The tri-axle is of a fixed design and each wheel pivots on the individual axle section. Preferably, the axle sections are welded to each other.

A nozzle for a cleaner includes a nozzle housing having a suction flow path through which air containing dust flows, a first rotation cleaning unit and a second rotation cleaning unit located on a bottom side of the nozzle housing, the first rotation cleaning unit and the second rotation cleaning unit being spaced apart from each other in a left-right direction of the nozzle housing, each of the first rotation cleaning unit and the second rotation cleaning unit having a rotation plate, a driving device located in the nozzle housing, and a water tank located on the nozzle housing, the water tank being configured to store water to be supplied to the first rotation cleaning unit and the second rotation cleaning unit. The water tank includes a first chamber, and a second chamber spaced apart from the first chamber in the left-right direction of the nozzle housing.

A machine for cleaning surfaces comprises a main body and a handle portion configured to move the main body along a determined advancing direction. The main body is equipped with a cleaning brush positioned adjacent to the surface to be cleaned, and a first and a second squeegee element positioned at opposite sides of the cleaning brush. The main body provides, furthermore, a first and a second suction mouth positioned at the first and the second squeegee element, respectively, connected to a suction device by a suction circuit. This comprises a deviation device configured to alternately and selectively pneumatically connect the first suction mouth, or the second suction mouth and the suction device, and to pneumatically disconnect, instead, the other suction mouth.

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.
