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.

A floor cleaning machine with a base, a control handle and a joint that permits that permits the handle to be pivoted in arbitrary directions relative to the base. The joint has first and second joint elements that are each attached to a corresponding of the base and the control handle. The first joint element has an envelope in the shape of a ball socket and is received into the second joint element. The first joint element is pivotable relative to the second joint element about a stationary fulcrum. The center of the envelope is non-displaceable relative to the second joint element. Grooves, which run in an arcuate manner, are provided on one of the first and the second joint elements, while corresponding engagement parts are provided on the other one of the first and the second joint elements and extend into corresponding ones of the grooves.

An apparatus and method for monitoring the productivity of a portable machine are provided. The method includes receiving motion data for at least one component of the portable machine from a multi-axis accelerometer, receiving position data for the at least one component from a process parameter sensor communicatively coupled to the at least one component, and determining, based on the received motion data and the received position data that the at least one component is oriented in a predetermined position for productive operation. The method also includes determining an area of productive operation using at least one physical dimension of the at least one component and the received motion data when the at least one component is oriented in the predetermined position for productive operation and incrementing a total area counter based on the determination.

A hand-guided floor treatment device includes a bottom part, which includes at least one tool which is rotatable on a floor by a drive, as well as a guide part which includes at least one handle and is connected to the bottom part by an articulated arrangement which is developed in such a manner that the guide part, proceeding from a perpendicular, is pivotable in relation to the perpendicular in angular positions rotating in all directions and is operatively connected to the bottom part so as to transmit torque in an angularly limited manner in each angular position in relation to the perpendicular. The at least one rotatable tool is arranged in such a manner on the bottom part that when the floor treatment device is operating the at least one rotatable tool exerts permanent linear propulsion on the bottom part.

A robot cleaner of the present disclosure comprises a main body configured to travel in a cleaning zone and to suction a foreign substance on a floor in the cleaning zone, an image sensor provided on the main body and configured to obtain an image of a predetermined area at a front side of the main body, a first light source provided on the main body and configured to emit a first pattern of light to a first sub-area of the predetermined area and a second light source provided on the main body at a position below the first light source and configured to emit a second pattern of light to a second sub-area of the predetermined area, the first sub-area being located lower than the second sub-area.

A robot cleaner includes a main body, a moving device to move the main body, and a control unit at the main body to recognize an area requiring cleaning. When the control unit recognizes the area requiring cleaning while in a standby state of the robot cleaner, the control unit controls the moving device so that the main body moves from a standby position to the area requiring cleaning to clean the area based on the control unit recognizing the area requiring cleaning.

A robot cleaner includes a main body, a moving unit for moving the main body, a cleaning module capable of being brought into contact with a floor surface at at least part of a lower surface thereof, and a module drive unit for controlling an angle of inclination of the lower surface of the cleaning module with respect to the floor surface.

A nozzle comprising a first light and a second light, wherein one of the lights is used to detect certain materials, such as bodily fluids, pet messes and stains and the like, while the other light is used for illuminating an area to be cleaned. The lights may be integrally incorporate into a nozzle or removably detachable therefrom.

A protective strip for protecting a fixture includes a piece of flexible material having a first edge and a second edge, and a plurality of magnets spaced along the first edge. In another example, a system for protecting a fixture includes a protective strip having a plurality of magnets spaced along a first edge, and a cart. The cart has a vertical member configured to hold the protective strip when the protective strip is rolled. A method is also disclosed.
