A method of controlling a moving robot is provided. The method of controlling a moving robot includes the steps of: (a) performing a basic motion of the moving robot which moves on a rotating mop; (b) measuring the slip rate of the moving robot; and (c) controlling the travel of the moving robot.

A surface cleaning tool including a housing forming a handle, a motor, a fluid reservoir coupled to the motor for rotational movement, a cleaning head coupled to and rotatable with the fluid reservoir, and a valve configured to control the flow of fluid from the fluid reservoir to the cleaning head. The valve is actuated by movement of the fluid reservoir from a first position to a second position relative to the cleaning head.

A steam cleaning apparatus may include a wand, a cleaning assembly coupled to the wand, the cleaning assembly including a steam generator, and a cleaning head pivotally coupled to the wand. The cleaning head may include a plurality of cleaning pads, a pad motor having a motor driveshaft, a drivetrain configured to transfer rotational motion of the motor driveshaft to each of the plurality of cleaning pads such that a rotation of the motor driveshaft causes a corresponding rotation in each of the plurality of cleaning pads, and a temperature sensor positioned proximate to the drivetrain, the temperature sensor being configured to measure a temperature of the drivetrain.

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 grinding head for a floor grinding machine for grinding floor surfaces of stone or stone-like material. Such a grinding head comprises a lower casing member, comprising a lower support and an upwardly extending edge portion, and an upper casing member, comprising an upper cover and a downwardly extending edge portion, wherein the upper casing member is joinable to the lower casing member by causing axially distal portions of the edge portions to bear on each other.

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 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.
