A cleaner includes: a body which forms an outer appearance; and a mop module which is detachably connected to the body. The mop module includes: a pair of spin mops which contacts a floor while rotating clockwise or counterclockwise when viewed from a top; and a module housing which connects the pair of spin mops. The cleaner may travel autonomously due to the rotation of the spin mops.

Walk-behind floor treatment machine comprising: a base portion provided with and supported by at least one rotatable work head for treating the floor, a handle portion for steering or guiding the machine along a working direction of travel and adapted to be pivotable with respect to the base portion, drive means for rotating the work head with respect to the base portion, floor-engaging wheel means for supporting the handle portion, the wheel means having a substantially transverse axis of rotation so as to permit travel in the working direction, the wheel means being coupled to the base portion by a linkage which permits vertical travel of the base portion and associated work head or heads with respect to the wheel means, but which provides transverse constraint to limit or prevent yawing of the base portion with respect to the wheel means, wherein a lower region of the handle portion is pivotably connected to the wheel means so that the handle portion may pivot through a generally vertical arc, and wherein a handle pivot lock mechanism is provided in which the adoption of a predetermined handle portion orientation permits one or more locking feature to act on one or more corresponding constraint feature so as to prevent pivoting movement of the handle portion with respect to the linkage, whereby tilting back of the locked handle portion causes a corresponding rise of the linkage and base portion with work head so as to lift them from the floor surface, wherein a squeegee suction device is provided for collecting and entraining liquid lifted from a floor surface over which the machine travels, the squeegee suction device being attached to the wheel means via one or more trailing arm which is attached at one end region to the squeegee device and at the opposite end region is pivotably attached to the wheel means for pivoting co-axially about the said transverse axis of rotation, the arrangement being such that the trailing arm and squeegee may pivot up or down about the transverse axis as they trail behind the treatment machine.

The present disclosure relates to a cleaning assembly and a smart cleaning device. The cleaning assembly is capable of being mounted on a machine body of a smart cleaning device and includes a connecting plate and a soft cleaning body, wherein the connecting plate and the soft cleaning body are detachably connected through a slide assembly, the slide assembly includes a mounting groove and a guide bar which are mutually matched, the mounting groove is provided on one of the connecting plate and the soft cleaning body, and the guide bar is disposed on the other one of the connecting plate and the soft cleaning body.

Multiple floor treatment operations, such as burnishing, polishing and scrubbing, may be performed using a single floor treatment machine having a motor, the speed of which is governed by a controller that responses to sensor signals indicative of the type of floor treatments pad or pads operatively coupled to the motor.

The present disclosure relates to a robotic cleaner. The robotic cleaner may be configured such that an imaginary plane passing mop contact portions having a small area passes through the center of gravity of the robotic cleaner, thereby travelling while the mops effectively scrub a floor surface.

A long rod cleaning machine can prevent swinging due to partial contact and also perform local cleaning. A scrubber includes an electric motor, a tip tool including a cleaning portion, a head to which the tip tool is attachable, a rod, and a rotator between the head and the rod. The tip tool is attached in a manner movable with a driving force from the electric motor. The head includes a peripheral portion surrounding the cleaning portion and including a surface-cleaning lateral portion to be in contact with a cleaning target surface together with the cleaning portion. The rotator includes a rotation restrictor connecting the head to the rod in a manner rotatable relative to the rod about at least two axes. The rotation restrictor partially or fully restricts rotation of the head.

A cleaner includes a body, a left spin-mop module and a right spin-mop module configured to perform mopping, and a water supply module configured to supply water to the left spin-mop module and the right spin-mop module. The water supply module includes a water tank to store water therein, a pump to pressurize the water in the water tank to move the water to the left spin-mop module and the right spin-mop module, a first supply pipe connecting the water tank and the pump, a common pipe connected to the pump, the common pump configured to guide movement of the pressurized water from the pump, a first branch pipe configured to guide a first portion of the water in the common pipe to the left spin-mop module, and a second branch pipe configured to guide a second portion of the water in the common pipe to the right spin-mop module.
