A cylindrical brush with an improved core and a mating driving hub have axially inclined splines that engage one another to form an improved cylindrical brush assembly for a floor maintenance machine.

A hand scrubbing device designed for automated and efficient cleaning of hands. The present invention features a housing with a sloped bottom wall for fluid drainage, supporting a chamber that houses three brushes: a lower brush, an upper brush, and a center brush. The lower and upper brushes rotate in opposite directions to scrub the hand, while the center brush focuses on cleaning the fingertips. A motor powers the brushes, and a water source is fluidly connected to a spray nozzle. A micro switch is engaged when a hand is inserted between the upper and lower brushes, activating both the motor and the spray nozzle. The device offers an efficient, accessible solution for thorough hand cleaning and can be adapted for use in various industries where improved hygiene is essential.

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.

The invention concerns a toothbrush comprising a brushing roller (4), a drive shaft with a first end secured to said brushing roller (4), said toothbrush comprising a first casing (30) within which runs said drive shaft, as well as a cover (8), made of a first material, having an internal face facing said roller (4), said drive shaft comprising an extremal segment emerging from said first casing (30) and including said first end, said brush comprising a bearing receiving said extremal segment, said toothbrush comprising a protective piece (9) made of a second material softer than said first material, said protective piece (9) cladding said internal face and projecting from the latter to form a lip (90), said protective piece (9) forming said bearing.

Oral hygiene instruments.

Electric toothbrush (1) comprising an electric motor as well as a brushing organ (3) of the teeth connected to said electric motor to be rotated by the latter, said electric toothbrush (1) being characterized in that it comprises a device for measuring an electrical quantity representative of a contact pressure between the brushing organ (3) and the teeth, as well as a processing unit connected to said measurement device to emit a first warning signal when the value of said electrical quantity measured by said measurement device is greater than a predetermined threshold.

The present invention, a cylindrical rotary tire brush element with an integrated wear indicator, is intended to replace the prior art cylindrical rotary tire brush element in a prior art rotary tire brush assembly. The cylindrical rotary tire brush element with integrated wear indicator is intended as a drop-in replacement to the prior art cylindrical rotary tire brush element of a prior art rotary tire brush assembly. The invention is made from at least two homogeneous pluralities of bristles, with each homogeneous plurality of bristles having the same purpose, material, color, and specified length. At least one plurality is a cleaning bristle of a first color and first specified length. At least one plurality is an indicator bristle of a second color and a third specified length, where the second color is a highly noticeable color such as yellow, red, orange, green, or white. The third specified length is equal to the minimum acceptable actual length of the cleaning bristles.

A surface cleaning apparatus has a rotatably mounted brush. The brush has first and second microfiber pads separated by bristles.

A 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.

A cleaner head for a vacuum cleaner includes a suction cavity having an opening through which debris enters the cleaner head, and an air outlet, and an agitator mounted in the suction cavity in a cantilevered manner for rotation relative thereto. The agitator is conical in shape and has a first, free end and a second end which has a larger diameter than the first end. The air outlet is located adjacent the free end of the agitator.

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.
