A lower-surface brush includes a base portion, a first cleaning portion and a second cleaning portion. The first cleaning portion is provided on an upper surface of the base portion to project upwardly from the upper surface of the base portion and extend in one direction through a geometric center of the base portion in a plan view. The second cleaning portion is provided on the upper surface of the base portion to project upwardly from the upper surface of the base portion and extend along an outer edge of the base portion. Alternatively, one or a plurality of pairs of second cleaning portions may be provided on the upper surface of the base portion to project upwardly from the upper surface of the base portion and be opposite to each other with the first cleaning portion interposed therebetween.

The present invention relates to a novel motorized broom device. The device is designed to reduce the time it takes to clean virtually any type of indoor or outdoor ground surface. The device comprises an elongated rod having a handle and trigger button at one end, and two wheels positioned on opposite ends of the cylinder of broom bristles, at the other end. The broom is powered via rechargeable batteries and the handle is expandable and adjustable to a desired angle. Users can activate the trigger button and adjust the handle at a desired angle for cleaning. Dirt and debris are quickly and easily displaced via the cylinder of broom bristles which spin upon activation.

The invention relates to a device for combing and conditioning artificial turf, which comprises a handle (1), a pole (2), a head (3) which houses an electric motor (4), and a pair of brushes (5) driven by the electric motor (4), the brushes (5) being configured for combing and conditioning the artificial turf, and such that the brushes (5) have a helical shape.

A cleaning roller is mountable to a cleaning robot. The cleaning roller includes a sheath comprising a shell, an outer diameter of the shell tapering from a first end portion of the sheath and a second end portion of the sheath toward a center of the roller. The cleaning roller further includes a core including a central portion interlocked with the sheath to rotationally couple the core to the sheath and inhibit relative translation of the sheath and the core along an axis of rotation. An inner surface of the sheath and an outer surface of the core define an air gap therebetween, the air gap extending from the central portion of the core longitudinally along the axis of rotation toward the first end portion or the second end portion.

A rotatable agitator is used in a surface clearing head of a surface cleaning apparatus. The agitator is coupled to the cleaning head at least partially within an agitator chamber and is rotated about a pivot axis. The agitator includes an elongated agitator body and a hair migration portion. The hair migration portion includes a continuous row of bristles and a sidewall. The continuous row of bristles and sidewall are at least partially revolved around and extend along at least a portion of the pivot axis from one of a collection area or a first end region of the agitator and either another collection area or a second end region of the agitator. The sidewall extends substantially parallel to the continuous row of bristles within the hair migration portion. The continuous row of bristles and sidewall are configured to reduce hair from becoming entangled in the bristles and to migrate hair towards the collection area or the first end region of the agitator.

A pipe de-burring assembly for de-burring a pipe and a pipe fitting includes a cylinder that has a pair of wells each extending therein to insertably receive a respective one of a pipe and a pipe fitting. A shaft extends lengthwise through the cylinder and the shaft is rotatably coupled to a power tool to rotate the cylinder. A plurality of first bristles is each of the first bristles is coupled to the shaft and each of the first bristles frictionally engages an inside surface of the pipe fitting for de-burring the inside surface of the pipe fitting. A plurality of second bristles is each coupled to the cylinder and each of the second bristles frictionally engages an outside surface of the pipe to de-burr the outside surface of the pipe.

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.

The present invention relates to a cleaning appliance and a method for a cleaning appliance. In particular, a cleaning appliance is disclosed, comprising: a housing, comprising an opening facing toward a surface to be swept; a sweeping brush, having a connection part by means of which the sweeping brush is mounted in the housing, and being capable of rotating about a rotation axis by receiving a driving force, so as to perform a sweeping operation; and a toothed structure arranged close to an end of the sweeping brush, the toothed structure being provided between the housing and the sweeping brush and comprising multiple teeth, the multiple teeth extending from one of the housing and the sweeping brush toward the other of the housing and the sweeping brush. The cleaning appliance of the present invention is at least able to prevent or at least reduce the entry of foreign matter into a gap, as well as promptly trigger protection measures when necessary to remind a user to deal with the problem, in order to avoid failure due to melting of the housing and sweeping brush in a connection region.

A cleaning device includes at least one T-shaped frame and a first sheet roll surrounding an internal space. The T-shaped frame abuts the internal space. First and second rollers are spaced apart from each other within the internal space and are disposed at opposite first and second ends of the at least one T-shaped frame, such that the first sheet roll abuts each of the first and second rollers. A third roller, exterior to, and spaced apart from, the first sheet roll, rotatably attached to the at least one T-shaped frame at a third end thereof.

A vacuum cleaner includes a head unit that suctions foreign substances from a surface to be cleaned together with air. The head unit includes a first suction guide having a first suction chamber therein and a second suction guide disposed on a rear side of the first suction guide and having a second suction chamber therein, and the first suction chamber suctions air through a first degree of vacuum and the second suction chamber suctions air through a second degree of vacuum higher than the first degree of vacuum.
