Disclosed is a vacuum cleaner. The vacuum cleaner according to the present disclosure includes a main body and a suction nozzle. The suction nozzle includes a housing and a rotating brush. The rotating brush includes a first rotating brush, a second rotating brush, and a coupler. The coupler couples the first rotating brush and the second rotating brush so that a rotation axis of the first rotating brush and a rotation axis of the second rotating brush are positioned on the same line.

Brush, in particular toilet brush, with a brush head and a handle. The brush head can be detachably pushed onto the handle. The handle has a release mechanism for the brush head.

A customizable cleaning brush, including a main body, a plurality of head members removably connected to at least a portion of the main body to brush, scrub, and massage a body of a user, a plurality of operation controls disposed on at least a portion of a first side of the main body to perform at least one of a rotation, oscillation, and vibration of the plurality of head members, and a plurality of pressure controls disposed on at least a portion of a second side of the main body to perform at least one of a speed control and a pressure control of the plurality of head members.

An oral care implement including a head and a plurality of cleaning elements which may include a first annular cleaning component and a second annular cleaning component. The first annular cleaning component may have a first inner surface defining a first cavity and a first distal end that is sloped from a first low point to a first high point. The second annular cleaning component may a second inner surface defining a second cavity and a second distal end that is sloped from a second low point to a second high point. The first annular cleaning component may located within the second cavity of the second annular cleaning component. The first and second distal ends may be sloped in opposite directions.

A segment for detachably arranging on a carrier, which can be rotatably mounted relative to an axis of rotation, for forming a disc brush or for forming a cleaning, grinding or polishing disc, includes a segment body, wherein multiple bristles protrude from the underside thereof or an abrasive grit and/or a fiber structure is arranged on the underside thereof, wherein the segment body has a segment guide extending in the radial direction in relation to the axis of rotation of the carrier on a radially internal edge and spaced apart from an external—in relation to a circumferential direction—lateral edge of the segment body, which segment guide is designed to cooperate with a corresponding carrier guide formed or arranged on the carrier for arranging the segment on the carrier.

An interchangeable-tool machine interface for a cleaning brush, includes a drive interface and output interface that are separable and connectable without tools and are separable or connectable in several discrete angular positions by axial displacement along a common axis of rotation. The output interface has centering walls and resiliently displaceable latching-means walls, the centering walls and the resiliently displaceable latching means walls are arranged so as to be angularly offset from one another in the circumferential direction about the axis of rotation. The drive interface has centering and mating latching-means walls that are arranged so as to be angularly offset from one another in the circumferential direction about the axis of rotation and, per wall, are designed to correspond both to the centering walls and to the latching means walls of the output interface.

A cleaning tool for cleaning accumulated charred food material on grill grates. The cleaning tool is of a two-prong tuning fork shape that has a handle and a cleaning head. A shaft extends between the two prongs of the cleaning head. Several cleaning discs are slidably provided between the two prongs over the shaft wherein two adjacent cleaning discs are separated by one or more spacer discs. the cleaning discs scrap the accumulated material from the grill bars.

An agitator for a vacuum cleaner includes an agitator body and a resiliently deformable flap. The resiliently deformable flap includes a front face, a rear face, and one or more protrusions extending outwardly from the front face. An agitator for a vacuum cleaner includes an agitator body and a bristle strip and/or a plurality of tufts arranged in one or more rows along the agitator body. The bristle strip and/or a plurality of tufts includes a first bristle group including a plurality of nylon bristles and at least a second bristle group including a plurality of para-aramid bristles.

A meso-abrasive dentifrice formulation of from 15 wt % to 30 wt % a first abrasive, from 10 wt % to 15 wt % a second abrasive, and excipients. The second abrasive is silica and is different from the first abrasive. A system is also disclosed for cleaning a human oral cavity having the disclosed meso-abrasive dentifrice formulation and an oscillating cup for delivery of the dentifrice formulation. The system demonstrates a Cleaning Efficiency Index (CEI) of from 2.34 to 2.45. The system demonstrates an Increase in Gloss Score of greater than 28 and a system Relative Dentin Abrasiveness (RDA) value less than 100.
