The cleaning device includes a main body and at least one drive wheel. The at least one drive wheel is arranged on the main body. The main body can walk on the surface to be cleaned by means of the at least one drive wheel. The cleaning device further includes a driving mechanism, a movable bracket, and a cleaning assembly. The driving mechanism is arranged on the main body, the movable bracket is movably connected to the bottom of the main body, and is connected to the driving mechanism. The movable bracket reciprocates along the direction parallel to the surface to be cleaned under the driving action of the driving mechanism. The cleaning assembly is detachably connected to the movable bracket.

A robotic cleaner may include a chassis, an agitator assembly configured to engage a surface to be cleaned, and a lift mechanism moveably coupling the agitator assembly to the chassis. The lift mechanism may include a biasing mechanism. The biasing mechanism may be configured to generate a biasing force that urges the agitator assembly in a direction away from the surface to be cleaned. The biasing force may be insufficient to lift the agitator assembly from the surface to be cleaned.

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.

The present disclosure relates to a liquid container and an autonomous cleaning robot. The liquid container may include a container case and a cleaning cloth that is removable and mounted on the container case. The cleaning cloth may include a first guiding member disposed thereon. The container case may include a second guiding member. The first guiding member and the second guiding member cooperate with each other to define an assembly direction of the cleaning cloth. The cleaning cloth can be installed correctly by defining the assembly direction of the first guiding member and the second guiding member.

A surface cleaner is disclosed having abase moveable along a surface and an operating component configured to perform a function of the cleaner. The surface cleaner includes a sensor configured to generate a signal based on the surface and a controller in communication with the sensor and the operating component. The controller is operable to convert the signal from a time domain to a frequency domain to generate a surface fingerprint. Furthermore, the controller is operable to control the operating component based on the surface fingerprint.

The invention relates to an apparatus for cleaning. The apparatus comprises a cleaning member adapted to engage a surface to be cleaned; a support member for supporting the cleaning member, with the cleaning member being resiliently movable between an extended position and a retracted position relative to the support member in response to an external force applied to the cleaning member; one or more engaging members provided at the support member; wherein the engaging members are adapted to engage the surface when the cleaning member is arranged at the retracted position such that further retraction of the cleaning member is substantially prevented.

A cleaning machine may include: a first brush comprising a first brush shaft extending in a left-right direction and a first brush body held by the first brush shaft; a second brush comprising a second brush shaft extending in the left-right direction and a second brush body held on the second brush shaft; a brush supporting member supporting each of the first brush and the second brush such that the first brush and the second brush are rotatable; a body supporting the brush supporting member such that the brush supporting member is pivotable; and a pivot mechanism configured to pivot the brush supporting member with respect to the body. At least the first brush may move with respect to the body in an up-down direction when the brush supporting member pivots with respect to the body.

An autonomous floor cleaner includes a tank adapted to hold liquid and/or debris, a brushroll to agitate a surface to be cleaned, and a position setting mechanism for the brushroll. The position setting mechanism can include a height setting feature on the tank to set the height of the brushroll within a brush chamber.

A floor treatment facility includes a chassis, a running gear for guiding the chassis over a floor, a treatment facility for treating the floor, a suction mouth, and a guide for applying the treatment facility movably along a predetermined path in relation to the chassis. The path extends in a vertical direction in relation to the floor and the path encloses a predefined angle with a plane parallel to the floor when the floor-treatment facility is standing on an even floor. The angle is at most approximately 45°.

A cleaning device includes a main body, a driving assembly, and a cleaning assembly. The driving assembly includes a driving device, at least one transmission member and a movable bracket. The driving device is arranged on the main body, and has a driving shaft extending toward the bottom of the main body. The movable bracket can be movably connected to the bottom of the main body, and is spaced from the driving shaft. The movement direction of the movable bracket is substantially perpendicular to the extension direction of the driving shaft. The at least one transmission member is connected between the movable bracket and the driving shaft. The driving shaft of the driving device drives the movable bracket to reciprocate back and forth through the at least one transmission member. The cleaning assembly is detachably connected to the movable bracket.
