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 provided on 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 comprises a base having a suction nozzle adapted to be moved along a surface to be cleaned, and a hair collection assembly carried by the base and having a hair collection element adapted to collect hair from the surface to be cleaned as the base moves along the surface to be cleaned.

An autonomous coverage robot includes a cleaning assembly having forward roller and rearward rollers counter-rotating with respect to each other. The rollers are arranged to substantially maintain a cross sectional area between the two rollers yet permitting collapsing therebetween as large debris is passed. Each roller includes a resilient elastomer outer tube and a partially air-occupied inner resilient core configured to bias the outer tube to rebound. The core includes a hub and resilient spokes extending between the inner surface of the outer tube and the hub. The spokes suspend the outer tube to float about the hub and transfer torque from the hub to the outer tube while allowing the outer tube to momentarily deform or move offset from the hub during impact with debris larger than the cross sectional area between the two rollers.

A self-propelled vacuum cleaner has a main housing having a bottom wall formed with an aperture, floor-engaging wheels on the main housing, and a drive in the main housing for rotating the wheels and advancing the main housing in a normal horizontal travel direction. A module housing projecting through the aperture forms a brush compartment defining a downward directed suction opening having relative to the direction a leading edge and a trailing edge. The module housing is supported in the main housing for limited vertical movement of the module housing relative to the main housing. A brush in the module housing is engageable through the opening with a floor beneath the opening, and a blower in the module housing having an intake connected via a duct to the brush compartment for aspirating air through the opening and past the brush into the module housing.

A cosmetic and grooming vacuum is an apparatus that cleans and removes unwanted particulate from a user's face such as debris, hair, or makeup. The apparatus includes a casing, a vacuuming mechanism, a filtering container, an exhaust port, and a plurality of accessory nozzles. The casing houses and serves as a base for the other components of the apparatus. The vacuuming mechanism is used to lift and remove the unwanted particulate off of the user's skin. The filtering container is used store the unwanted particulate within the casing so that the unwanted particulate can be disposed of at a later time. The exhaust port allows the outward fluid flow from the vacuuming mechanism to exit the casing. Each accessory nozzle is used to uniquely modify the suction force of the vacuuming mechanism such as with a brush nozzle or a pinpoint tip nozzle.

A vacuum cleaner includes a suction head including a cover and a bottom plate provided with a suction hole through which air is sucked from a surface to be cleaned and rotatably combined with the cover. The bottom plate is rotated in one direction relative to the cover when the suction head moves forward, and is rotated in the other direction relative to the cover when the suction head moves backward. Further, the vacuum cleaner includes a brush base including brushes and movable upward and backward between the cover and the bottom plate. The brush base includes indicating parts exposed to the outside of the cover and forming at least a portion of the external appearance of the suction head.

A nozzle assembly usable with an upright vacuum cleaner, comprising: a nozzle assembly body; a drum brush unit disposed in the nozzle assembly body, the drum brush unit having a drum brush disposed to move dirt or dust adhered to a surface to be cleaned while coming in rotational contact therewith; a subsidiary brush unit disposed in front of the drum brush unit, and the subsidiary brush unit having a subsidiary brush to preliminarily move the dust or dirt adhered to the surface to be cleaned before the drum brush moves the dirt or dust adhered to the surface to be cleaned; and a locking unit disposed to the drum brush unit to selectively fix the subsidiary brush unit to the drum brush unit, wherein the subsidiary brush unit is rotatably connected to the drum brush unit to selectively maintain a contact state or a non-contact state to the surface to be cleaned, and, when the subsidiary brush unit maintains the contact state to the surface to be cleaned, the locking unit fixes the subsidiary brush unit to the drum brush unit.
