A vehicle wash component includes a hub portion with a first hub section and a second hub section. The first hub section includes a first distal end and a first proximate end opposite the first distal end. The first hub section defines a first axis of rotation. The second hub section includes a second distal end and a second proximate end opposite the second distal end. The second hub section defines a second axis of rotation. A connector device rotatably couples the first hub section to the second hub section. An actuator is in communication with the first hub section to effectuate movement of the first distal end between a retracted position and an extended position. In the retracted position, the first axis of rotation and the second axis of rotation are parallel. In the extended position, the first axis of rotation is at a non-90 angle with respect to the second axis of rotation.

A treatment element for attachment to a wash media element includes a tab portion for engaging and effecting attachment to the wash media element. A treatment head is connected to the tab portion and is configured to engage a vehicle exterior. The treatment head including a plurality of individual finger portions that are moveable with respect to one another.

A building cleaning system for cleaning a side of a building can include an elongate brush structure that is rotated by an electric motor, a frame for supporting the brush structure that can be oriented to face toward the side of the building, and a plurality of air moving devices mounted to the frame for generating counterforce to force the frame toward the building. The air moving devices can including fans or blowers. The air moving devices can be being spaced apart from one another in an orientation that extends along the length of the frame. A lift arrangement can be provided for moving the frame along the side of the building.

A hair styling tool having a plurality of bristles and one or more movable members extending radially outward from the core and movable between opposing positions is provided. The movable members move between a retracted position where the divider is fitted between and even with or slightly above or slightly below the bristles to engage the hair and an extended position where the divider is moved out beyond the bristles to disengage the hair from the bristles. The hair styling tool having the movable member which engages and disengages the hair with the bristles minimizes tangling of the hair while brushing. The hair styling tool may be a rotating brush optionally equipped with a motor.

The present document describes a device for clearing an area around an elevated object. The device comprises: a main frame; a blower device operably mounted on the main frame for blowing high flow air towards the area around the elevated object; and a sweeping device operably mounted to and extending from the main frame for clearing the area around the elevated object. The present document further describes a method for clearing the area around an elevated object.

Provided are a scrubber brush assembly and a vacuum cleaner having same. The scrubber brush assembly includes a roller brush body and a scraping sleeve. The roller brush body is rotatable around a first rotation center line and has a bristle (12) provided thereon. The scraping sleeve is rotatable around a second rotation center line noncoincident with the first rotation center line and sleeved over the roller brush body. The scraping sleeve has a scraping sleeve hole defined thereon. The bristle is adapted to be extended out of or retracted into the scraping sleeve hole in a wall thickness direction of the scraping sleeve.

A cleaning brush and an intelligent cleaning device are provided. The cleaning brush includes: a shaft lever having two first end portions; an end portion member mounted on a first end portion, wherein the end portion member has a blocking structure for preventing entanglements from excessively extending away from the cleaning brush, the end portion member and the first end portion have mounting structures mutually matched; and the mounting structure includes a guide sleeve configured to be sleeved onto the first end portion; and a cylindrical member, coaxial with and sleeved onto the shaft lever, having two second end portions. A second end portion corresponding to the end portion member covers at least a portion of the guide sleeve of the corresponding end portion member.

An automatic cleaning apparatus, including a first rolling brush including a first brush member, and a second rolling brush arranged substantially in parallel to the first rolling brush and including a second brush member. As the first rolling brush and the second rolling brush rotate, the first brush member and the second brush member rotate to a position where the first brush member and the second brush member approach each other, and a point where the first brush member and the second brush member approach each other moves dynamically in a predetermined direction.

An allergen reduction device may include a body, a dust cup removably coupled to the body, a plurality of agitators rotatably coupled to the body and disposed within respective agitator cavities defined in the body, a suction motor disposed within the body and configured to cause air to flow along corresponding cleaning airflow paths from the agitator cavities into the dust cup, a hot air outlet fluidly coupled to the suction motor, the suction motor being configured to urge the air through the hot air outlet along a heated exhaust airflow path, and a heater positioned within the heated exhaust airflow path between the suction motor and the hot air outlet, the heater being configured to heat the air that is urged from the hot air outlet.
