A bathtub cleaner assembly includes a cleaner that has a handle portion extending upwardly from a reservoir portion that contains a fluid cleaning solution. A first scrubbing unit is coupled to the reservoir portion of the cleaner to engage a basal wall of the bathtub when the cleaner is positioned in the bathtub. The first scrubbing unit rotates when the first scrubbing unit is turned on to scrub the basal wall of the bathtub. A pair of second scrubbing units is each movably integrated into the reservoir portion of the cleaner to scrub a respective lateral wall of the bathtub when the cleaner is positioned in the bathtub. A spray unit is integrated into the cleaner to spray the fluid cleaning solution onto the first scrubbing unit and the second scrubbing units.

A handheld cleaning device includes a surface-moving portion and an upright portion. The surface-moving portion is in contact with a surface to be cleaned and is connected with the upright portion. The upright portion is configured to move the surface-moving portion in a case in which the surface-moving portion is in operation. The handheld cleaning device further includes a power battery configured to supply power to the handheld cleaning device. The surface-moving portion further includes at least two non-coaxial brushrolls configured to clean stains on the surface to be cleaned. The rotation speed of each brushroll is less than 3000 r/min.

A mobile cleaning robot can include a body, a drive wheel, and a plurality of skids. The drive wheel can be connected to the body and can be engageable with a floor surface of an environment. The drive wheel can be operable to move the mobile cleaning robot about an environment. The skids can be separate skids that can be connected to the body and can be engageable with the floor surface to support, together with the drive wheel, the mobile cleaning robot with respect to the floor surface.

Roller brushes for a cleaning and/or care devices, for example, for cleaning and/or care of floor coverings 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 may be arranged on the cylinder surface. The first bundle of bristles may be different from the second bundle of bristles.

A rotating grooming brush comprising a brush hub having grooming elements and shroud elements, and method for grooming a surface having an unwanted material thereon. The elements extend from the brush hub and may be positioned near its outer periphery. The elements may be grooming elements forming an array and shroud elements forming a shroud array. A rigid or elastomeric shroud extending from the brush hub surface may optionally be included about the edge of the brush hub, to the outside of the grooming elements. Rotation of the grooming attachment brush causes a low pressure region to build in the central area of the brush. This low pressure region creates a resulting force that forcefully attracts the grooming attachment brush to the surface to be groomed. The resulting force is controlled by the diameter of the brush hub, arrangement, of the elements and the speed of rotation.

A brush retrofit for mounting behind a snow plow blade of a snow removal vehicle is disclosed. The brush retrofit includes a base frame, a stationary brush assembly, a retrofit mount, a brush elevation actuator, and a retrofit mount. The stationary brush assembly is movably mounted to the base frame. The retrofit mount is configured to secure the base frame to a support structure of the snow removal vehicle behind the snow plow blade. The brush elevation actuator when activated, moves the stationary brush assembly relative to the base frame between a raised storage position and a lowered in-use position. The retrofit mount is configured to secure the base frame to a support structure of the snow removal vehicle behind the snow plow blade.

A cleaner includes a main body and a suction head connected to the main body to suck foreign objects into the main body therethrough, the suction head including a housing including a suction port, and a drum module disposed in the housing, and to be rotated to scatter the foreign objects to be sucked through the suction port so that the scattered foreign objects are drawn into the housing through the suction port, and the drum module including a drum body, a first blade coupled to outer circumference of the drum body, a second blade separated from the first blade in a circumferential direction of the drum body and having a mass greater than a mass of the first blade, and a mass compensation member arranged on the outer circumference of the drum body to compensate for a difference in mass between the first blade and the second blade.

The invention relates to a skin treatment device comprising a housing (10) with a handle section (11), a disc-shaped skin treatment element (21), a drive mechanism incorporated in said housing and coupled to said skin treatment element for driving said skin treatment element into rotational movement about a rotational axis, wherein said skin treatment element has a first skin treatment surface (22) and a second skin treatment surface (25), said first skin treatment surface (22) being oriented axially with respect to said rotational axis, said second skin treatment surface (25) being oriented radially with respect to said rotational axis and extending along a circumference of the skin treatment element.

Embodiments described herein generally relate to a brush, a method of forming a brush, and a structure embodied in a machine readable medium used in a design process are provided. The brush includes a body and a channel configured to deliver a cleaning liquid through holes in the body. The method forms the brush using 3D printing. The structure provides details for making the brush. The disclosure herein allows a method of forming a brush that does not require the removal of active porogen.

Methods of making a pet grooming and skin care appliance and grooming an animal with the appliance by rotating the appliance with a hand held power drill. The appliance includes a drum secured to a rigid arbor. The drum defines an axis of rotation and has an array of flexible and resilient fingers of specific durometer extending radially outward from the axis of rotation. The arbor extends coaxially away from a proximal end of the drum.
