A torque transmitting ball joint can include a spherical ball, a stem extending from the spherical ball, one or more pins coupled to the spherical ball, and a socket. The socket can define an opening sized to contain the spherical ball within the socket and one or more slots sized to accommodate a pin of the one or more pins. The one or more pins can be contained by the one or more slots and can translate within the slot as the spherical ball rotates relative to the socket about a pivot center. At least one of the one or more pins can abut a sidewall of its slot and transmit torque from the stem to the socket via the spherical ball when the stem and spherical ball rotates relative to the socket.

A surface cleaning device comprises a cleaning head having a housing, a fluid tank configured to store fluid and be in fluid communication with the cleaning head, a cleaning pad coupled to the cleaning head and configured to remove debris from a surface, and a plurality of nozzles distributed along the cleaning pad, wherein the fluid tank is configured to release at least some of the fluid such that the released fluid flows through the plurality of nozzles onto the cleaning pad.

A fluid dispensing scrubber includes a shaft having a first end and a second end; a fluid inlet configured to receive a first fluid from an external source; a reservoir configured to store a second fluid; a valve assembly configured to selectively mix the first fluid and the second fluid; a scrubbing head supported adjacent the first end of the shaft, the scrubbing head including a brush and a motor operable to rotate the brush; a battery pack supported adjacent the second end, the battery pack operable to provide power to the motor; and a dispensing nozzle configured to selectively dispense one or both of the first fluid and the second fluid, the nozzle supported on an exterior surface of the scrubbing head.

A floor cleaning and polishing device has a polishing pad for a surface which is rotationally engaged upon a pad driver operatively engaged to a frame. A first set of wheels on the frame allow for tilted movement. A second set of wheels are positionable to a deployed position to elevate the first set of wheels from the surface and position the polishing pad parallel to the surface. The device may have a light projector engageable for light disinfecting. The polishing pads are configured with a plurality of polishing fabric sections separated by recesses therebetween.

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.

A mop includes a floor cleaning portion, an upper absorbing portion located over the floor cleaning portion, the upper absorbing portion being configured to receive water supplied from a water tank to supply the water to the floor cleaning portion, and an attaching portion located over the floor cleaning portion, the attaching portion being connected to the upper absorbing portion. At least a portion of the attaching portion is located to overlap an outer edge of the upper absorbing portion in a vertical direction.

A handheld extraction cleaner includes a unitary body provided with a carry handle, and further provided with a supply tank, a suction nozzle, a recovery tank, and a suction source, all of which are carried by the unitary body. In one aspect, the recovery tank is configured to optimize the usable volume within the tank and a user's view of the collected dirty liquid within the tank, among other functions. In another aspect the recovery tank has an auto-close feature that automatically seals an outlet of the tank when the recovery tank is mounted to a tank receiver of the unitary body. In yet another aspect, the extraction cleaner has an agitator that slides out from a side of the unitary body. In still another aspect, the suction nozzle includes a cleaning angle guide skid to orient the extraction cleaner at an optimal cleaning angle. In a further aspect, the supply tank is a non-removable part located at a rear of the unitary body.

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.
