An autonomously traveling floor washer autonomously performs an appropriate cleaning operation so that a washing liquid does not remain on a floor surface. In accordance with a cleaning schedule, the autonomously traveling floor washer autonomously travels and performs cleaning of the floor surface using a squeegee and the washing liquid. If a washing liquid discharge position at a taught data obtaining time is not included in a squeegee movement track calculated based on a position and a width of the squeegee at the taught data obtaining time, the cleaning schedule is modified so that the washing liquid discharge position is included in the squeegee movement track.

A cleaner includes a body forming an external appearance, a rotating plate provided at a lower side of the body, a mop unit coupled to a lower side of the rotating plate so as to be in contact with a floor, a spin shaft connected to an upper side of the rotating plate so as to rotate the rotating plate, a water supply reservoir configured to surround a periphery of the spin shaft and spaced apart from the spin shaft so as to define a water supply space, and a water supply module configured to supply water to the water supply space. The rotating plate forms a water supply hole configured to interconnect the water supply space and the lower side of the rotating plate.

The present invention is an interface between an orbital or dual action machine and towels. The apparatus may directly connect to the orbital or dual action machine or may attach to a backing plate that is attached to the orbital or dual action machine. The quick connector is located concentric with the head of the orbital and dual action machine to provide balanced and even mechanical movement of the attached towel. The present invention provides an interface between an orbital or dual action machine and towels in order to take advantage of the mechanical action of the machines to provide faster and more efficient use of towels. An exemplary embodiment of the present invention is a towel quick connector pad having of a central opening with a retaining aperture for attaching and securing a towel.

An overload control device for use with a floor machine having an electric motor is disclosed. The overload control device can include a power input and a power output connectable to the electric motor. The device can include a load detector, a current sensor operative to sense a current value supplied to the motor via the power output, and a cutoff relay interconnecting the power input and the power output. The cutoff relay being operative to supply power from the power input to the power output when activated, and interrupt power when deactivated. A controller receives a load present indication from the load detector and activates the cutoff relay if a load is present. The controller receives a current value from the current sensor, determines if the current value is greater than a threshold value, and deactivates the cutoff relay when the current value is greater than the threshold value.

An orbital single-brush machine comprising a frame which rests on the floor and is provided with at least one movement handle; the frame being connected to a motor which is adapted to actuate with combined rotary and orbital motion a work tool that acts on the floor; the frame comprising a first substantially plate-shaped footing which is spaced apart from the floor, and a second substantially plate-shaped footing which supports the motor and is arranged below the first footing and is supported so that it can rotate freely by the first footing about an oscillation axis that is substantially parallel to the floor and substantially perpendicular to the advancement direction of the machine.
