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.

A floor polishing or grinding pad assembly is provided. In one aspect, a polishing or grinding pad assembly employs a flexible pad, a reinforcement layer or ring, and multiple floor-contacting tools such as abrasive disks. In another aspect, the reinforcement layer includes a wavy or undulating internal edge shape. A further aspect includes an inner ring edge having radially extending slots between pairs of radially enlarged tool mounting peaks. Still another aspect includes an insulator or spacer between a head of an abrasive tool and a reinforcement ring.

A cleaning appliance includes: a main body with a bottom side, the main body being assigned on the bottom side, which faces toward a floor to be cleaned, at least one cleaning body, the at least one cleaning body being mounted on the main body so as to be rotatable about an axis of rotation, the axis of rotation of the cleaning body being oriented perpendicularly to the bottom side. The at least one cleaning body is mounted in the main body such that, during cleaning, the axis of rotation is movable relative to the bottom side along a movement path which is oriented perpendicularly to the axis of rotation.

The present invention relates to a floor grinding apparatus (100) with a housing (110) having an interior space (111) open to one side, a carrier plate (120) rotatably mounted in the interior space (111) for receiving abrasives, and drive unit (130) adapted to rotate the carrier plate (120), the housing (110) having an inner dust sealing ring (112) with at least one recess (115), wherein the inner dust sealing ring (112) divides the interior space (111) into an inner portion (113) and an outer portion (114), and wherein the carrier plate (120) is disposed in the inner portion (114), at least one extraction opening (116) disposed in the outer portion (114), and an outer dust sealing ring (117) enclosing the interior space (111), the inner dust sealing ring (112) and the outer dust sealing ring (117) being arranged to define a common working plane parallel to the plane of rotation of the carrier plate (120).

A robot polisher has, in a box-shaped body part having a round shape in a plan view, right and left batteries, right and left wheel motors (not shown), and a pair of right and left wheels. The right and left wheel motors are rotationally driven by using the batteries as power supplies. The pair of right and left wheels can be individually rotated forward/backward by the respective wheel motors. On a lower housing, at the front-side lower part of the body part, a pair of right and left brushes are downwardly attached, which rotate in directions opposite to each other during traveling while being in sliding contact with a floor surface.
