Abstract: Drying and/or cleaning cloth has an elongated shape with a double-layered construction. Two sides are formed by cloth layers with an interior region in-between. The two sides are each bounded by two parallel longitudinal edges and two transverse edges. An opening is for reaching into the interior region between the two sides. The drying and/or cleaning cloth has a pentagonally configured region. In the pentagonally configured region one of the two transverse edges is aligned at right angles to the longitudinal edges and the other of the two transverse edges is formed by two angularly abutting front edge sections adjoining the corresponding longitudinal edges at an obtuse angle. The opening for reaching into the interior region between the two sides is provided in the region of the transverse edge aligned at right angles to the longitudinal edges.

Abstract: A robotic pool cleaner includes a cleaning body, a drive and a cleaning roller brush mechanism. The robotic pool cleaner filters liquid and/or contaminants in a pool through the cleaning body. The drive mechanism is connected to the cleaning body, which is driven to move in the pool in a working process of the robotic pool cleaner. The drive mechanism includes a drive wheel with a first outer ring gear. The cleaning roller brush mechanism is coupled with the first outer ring gear through a transmission belt, so that the cleaning roller brush mechanism is driven by the first outer ring gear to rotate relative to the cleaning body when the drive motor drives the first outer ring gear to rotate. The robotic pool cleaner improves cleaning efficiency and reduces wear of a cleaning roller brush, thereby prolonging the service life of the cleaning roller brush mechanism.
