A rolling brush assembly includes a rolling brush having a rolling brush roller, at least two brush bars, and a protruding strip extending lengthwise along an axis. Each brush bar extends lengthwise in a longitudinal direction of the rolling brush roller. The brush bars are arranged at intervals along a circumferential direction of the rolling brush roller with the protruding strip located between adjacent two brush bars. The at least two brush bars are fixed on the rolling brush roller in one of a flocking or an inserting manner. An engagement portion is formed between the brush bars and the rolling brush roller. A distance from an outer end of the engagement portion to the axis is less than a distance from an outer end of the protruding strip to the axis.

This invention relates to an automatic vehicle wash apparatus employing one or more rotary cloth or foam rubber brushes, and more particularly to the way how the rotary brush to vehicle surface contact is managed using one or more encoders connected to the rotating shaft of each brush and one or more programmable logic controllers (PLC). The encoders, recording the revolutions per minute (RPM) of each brush shaft, provide input to the programmable logic controller. If the RPM value is at or above the high RPM limit, the pivoted boom will move the brush toward the vehicle to achieve a desired brush-to-washable surface contact. If, on the other hand, the RPM value is at or below the low RPM limit, the pivoted boom will move the brush away from the vehicle to achieve a desired brush-to-washable surface contact.

A vacuum cleaner is disclosed. The vacuum cleaner according to the present disclosure includes a main body and a suction nozzle. The suction nozzle includes a housing, a driver, a rotating brush, and a detachable cover. A pressing button is mounted in the housing. The detachable cover is rotated about the rotational axis of the rotating brush to be mounted in the housing. The pressing button selectively blocks rotation of the detachable cover.

An autonomous cleaning robot includes a drive system to move the autonomous cleaning robot about a floor surface, a cleaning head on a bottom portion of the autonomous cleaning robot, a side brush on the bottom portion of the autonomous cleaning robot, and a vacuum system in pneumatic communication with the opening. The cleaning head is configured to direct debris from the floor surface into the autonomous cleaning robot as the autonomous cleaning robot moves about the floor surface. The side brush is rotatable about a rotational axis forming a non-zero angle with a floor surface, and the side brush comprising an opening.

A reconfigurable vacuum attachment may include a bell-shaped housing. The bell-shaped housing may have a bell-opening and a hose-interface. The hose-interface may be configured to hydraulically couple with a vacuum hose. A skimmer-plate may be attachable to the bell-opening and include a skimmer-aperture extending through the skimmer-plate. The reconfigurable vacuum attachment may further include a removable brush assembly. The brush assembly may host a rotatable brush coupled to a brush driver. The brush driver may be configured to hydraulically couple with the vacuum hose and convert water flow into a torque and spin the bristles. A buoy may be attached to the housing allowing the reconfigurable vacuum attachment to be used as a pool skimmer. The reconfigurable vacuum attachment is useful for skimming a pool surface and dislodging and vacuuming matter from a pool wall.

A vacuum cleaner including: a cleaner main body configured to generate suction force; and a suctioner including a head having a suction inlet to suck dust by the suction force and a brush drum rotatably provided in the suction inlet to sweep dust on a floor. The brush drum includes convex portions projected from an outer circumferential surface of the brush drum and spirally extended in a rotational axial direction of the brush drum.

An industrial robotic vacuum system for cleaning agricultural facility ventilation ductwork. The industrial robotic vacuum system generally includes a robotic vacuum head.

Embodiments of the present disclosure provide a tongue brush device comprising: a replaceable head assembly comprising: a brush head assembly at a proximal end of and substantially transverse to an upper housing, the brush head assembly comprising a drum roller with an application area having a predetermined surface profile effective to clean a tongue surface, the drum roller configured to be rotated about an axis using a drive source, and the upper housing comprising: a guard piece housing the brush head assembly, and a tongue guard oriented below the brush head assembly effective to prevent the drum roller from driving a tongue of a user between the guard piece housing and the brush head assembly when in use; and a base assembly configured to detachably couple with a distal end of the head assembly, the base assembly comprising a lower housing containing at least a portion of the drive source.

A powered toilet bowl brush for automatically cleaning an interior of a toilet bowl. The toilet bowl brush includes a splash guard member having a brush assembly disposed on a first side and a housing on an opposing side thereof. The splash guard member is sized to rest atop a perimeter of a toilet bowl and prevent liquid from splashing out of the toilet bowl when in use. A shaft extends from the housing and through the splash guard member, wherein a distal end of the shaft is secured to the brush assembly. The shaft is operably connected to a motor that moves the brush assembly along a vertical axis. In some embodiments, the brush assembly is rotatably secured to the shaft and is capable of rotating 360 degrees about the vertical axis. In operation, the brush assembly is activated to automatically clean the interior of the toilet bowl.

A hairstyling device of the rotary blower brush type may include a handle having two zones of different diameters D1 and D2. The first diameter is greater than the second (i.e., D1>D2), such that the greater diameter can accommodate a compressor. The compressor facilitates a substantially constant air flow. The smaller diameter zone corresponds to a gripping zone that facilitates more ergonomic handling compared to known devices.
