The invention relates to a cleaning device, in particular a floor-cleaning device, comprising a cleaning unit which is at least partly covered by an endless cleaning element that can be rotated continuously in relation to a surface to be cleaned during the action upon a surface to be cleaned. In order to devise a cleaning device in which regeneration of the endless cleaning element is particularly comfortable, the cleaning unit comprises at least one first roller part which can be placed on the surface to be cleaned and a second roller part, the radius of curvature of a roller subsection of the first roller part being different from a radius of curvature of a roller subsection of the second roller part.

A floor cleaning machine is provided, in particular a hand-guided and/or hand-held floor cleaning machine, including a support device, at least one cleaning roller arranged on the support device, capable of being driven in rotation and provided with a cleaning substrate, a fan device for creating a suction flow, and a suction channel device for the suction flow which provides a suction channel operatively connected for fluid communication between the fan device and the at least one cleaning roller, wherein the suction channel has a mouth towards the at least one cleaning roller that includes a first and a spaced second mouth wall having a mouth opening therebetween, wherein the first mouth wall is positioned above the second mouth wall relative to the direction of gravity, wherein the first and/or second mouth wall are/is in contact against or protrude(s) into the cleaning substrate of the at least one cleaning roller.

The invention relates to a roller brush, in particular for a cleaning and/or care device, preferably for floor covering in the form of tiles, natural, artificial, blocks of concrete or wood, with a rotationally symmetrical cylinder which comprises a cylinder surface. At least one first plurality of a first bundle of bristles with a first brush and a second plurality of a second bundle of bristles with a second brush is arranged on the cylinder surface. The invention is characterised in that the first bundle of bristles are different from the second bundle of bristles.

An apparatus is provided which is capable of cleaning soiled concrete or other hard surfaces using significantly less water and detergent than typical pressure washers. A dual brush mode allows for more surface treatment. A safety electrical system allows the system to be used safely outdoors. The highly maneuverable maintainer utilizes industry standard components from floor maintenance equipment integrated with a horizontally stable wheeled platform, as well as, an adjustable and wear-compensating suspension system that can accommodate a variety of surfaces. The result is a low noise, low carbon footprint, low resource apparatus that moves easily in any direction while providing direct rotary brush scrubbing to clean soiled concrete or other hard surfaces.

A handheld extraction cleaner includes a unitary body provided with a carry handle, and further provided with a supply tank, a recovery tank, and a suction source, all of which are carried on the unitary body. The various components of the extraction cleaner can be arranged for a balanced weight in hand. The supply and recovery tanks are configured to optimize the usable volume within the tanks, among other functions. A powered cleaning head including a removable brushroll is provided on the unitary body.

A surface cleaning apparatus includes a separating and collection assembly defining a collection chamber which receives debris and has a debris outlet, a cover assembly having a pre-motor filter, a debris ejector, and a push rod operably coupleable to the debris ejector to displace the debris ejector relative to the debris outlet. The push rod can be accommodated by an opening of the pre-motor filter.

A multi-functional window washing and wiping device comprises mainly a device body and a retractable rod connected to the device body, wherein on the device body are disposed a toothed gear assembly comprising a plurality of toothed gears and a vortex rod for driving the toothed gear assembly, whose two ends are pivotally connected to wheels disposed on two sides of the device body. At least two tube bodies are disposed above the device body. When using the present invention, assemble a cleaning tool such as a brush, a sponge, or a piece of cloth on the toothed gear assembly; input detergent and water via the tube bodies; and hold the retractable rod, place the device body on a glass window, and move the device body along the glass window. The purpose of washing glass windows in buildings is achieved by rolling the cleaning tool by driving the toothed gear assembly via wheels or a motor without the risk of having window washers hang in mid-air.
