A vacuum cleaner comprises a cleaning head having a suction nozzle adapted to be moved along a surface to be cleaned, and a hair collection assembly carried by the cleaning head and having a hair collection element adapted to collect hair from the surface to be cleaned as the cleaning head moves along the surface to be cleaned.

A vacuum cleaner having a housing and a suction inlet thereon, the cleaner comprising a suction source in fluid communication with the suction inlet to produce a working airflow therethrough and a dirt container in fluid communication with the suction inlet and suction source. The housing further comprises a body defined by a central portion and a pair of extension arms that extend laterally outwardly from the central portion, wherein each extension comprises a mount, which receives a rotatable agitator thereon. A drive assembly is configured to counter-rotate each agitator with respect to the other agitator, and wherein the suction inlet is positioned on the housing rearward of, and between, each of the axes of rotation of each agitator. The counter-rotating agitators are operable to cooperate with the suction source to direct dust and debris outside the periphery of the housing along a converging debris path, towards the suction inlet.

A nozzle for a vacuum cleaner and a vacuum cleaner are provided. The nozzle may include a main nozzle; at least one movable nozzle rotatably coupled to the main nozzle; and a rotary cleaner provided inside of the main nozzle and the movable nozzle that cleans a floor surface using a rotary motion. The rotary cleaner may include a main shaft rotatably provided inside of the main nozzle, and at least one auxiliary shaft provided inside of the movable nozzle and connected to the main shaft. The at least one auxiliary shaft may rotate using a rotational force transmitted from the main shaft.

A cleaning head connectable to a vacuum cleaner comprises a cassette removeably mountable on the cleaning head. A rotatable bar has projecting cleaning elements engageable with a surface to be cleaned and the rotatable bar is removeably mountable in the cassette. A first cassette mounting assembly is coupled to the rotatable bar at a first end with a first spindle. A second cassette mounting assembly is coupled to the rotatable bar at a second end with a second spindle. The first and second cassette mounting assemblies have removable cover portions for shielding the first and second spindles from debris and the first cassette mounting assembly is rotatably coupled to and removable with the first spindle.

A nozzle assembly for use on a vacuum cleaner includes a base unit, an outlet coupled to the base unit and pivotable with respect to the base unit, one or more wheels coupled to the base unit, and a suction chamber coupled to the base unit. The outlet is configured for engagement with a suction tube of the vacuum cleaner. The suction chamber includes a first agitator configured to rotate in a first direction, a second agitator configured to rotate in a second direction opposite from the first direction, and a suction port arranged between the first agitator and the second agitator.

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 cleaner can include a cleaner main body including a suction motor configured to generate a suction force to suction air containing dust on a cleaning surface, the cleaner main body being configured to separate the dust from the air suctioned; a nozzle placed on the cleaning surface and configured to suck the air containing dust on the cleaning surface; and an extension tube to which the nozzle is detachably connected, one end connected to the nozzle and the other end connected to the cleaner main body to guide the air containing dust from the cleaning surface to the cleaner main body.

Various chair controls for enabling motion associated with human support surfaces is disclosed. Furthermore, these new structures adjust, at least in part, automatically to a wide variety of users. The way in which this automatic adjustment occurs, is through the generally, at least in part, vertical displacement of an occupant throughout a range of motion, such as recline, and where this generally, at least in part, vertical displacement accounts for the entirety of an occupants mass regardless of degree of motion and thus degree or amount of generally horizontal displacement while maintaining proper ergonomic relationships.

The present disclosure is generally directed to cleaning head for a vacuum system. The cleaning head includes an edge cleaner disposed on at least one side of the cleaning head to provide enhanced edge cleaning capabilities for the vacuum system.
