  • Patent number: 7979959
    Abstract: An accessory for a cleaning appliance includes a head having a housing, a downwardly-directed suction opening in the housing and a neck adapted for attachment to a hose or wand of the cleaning appliance. A rotatable connection is provided between the neck and the head for allowing rotation of the neck relative to the head. A wheel arrangement maneuverably supports the accessory on a surface to be cleaned and is mounted on the neck of the accessory. The wheel arrangement may normally be in contact with the surface to be cleaned, but the point or points of contact between the wheel arrangement and the surface to be cleaned are dependent upon the rotational position of the neck with respect to the head.

  • Publication number: 20110107553
    Abstract: A steerable vacuum cleaner and a method to steer the vacuum is described. The vacuum cleaner include: a base; a handle having a longitudinal axis and including a conduit; and a rotatable coupling pivotally attached between the base and the handle, with the coupling defining an air channel for providing a flow of air from the base to the conduit in the handle. The base of the vacuum rotates about the longitudinal axis while pushing the vacuum by twisting the handle. The rotatable coupling of the vacuum cleaner includes: an inner conduit having an outer surface; a compressible strip disposed on the outer surface of the inner conduit, wherein the strip is disposed the outer surface of the inner conduit; an outer conduit adapted to snugly fit over the strip and the first conduit; and a non-reactive high-viscosity lubricant disposed on the outer surface of the inner conduit adjacent the strip.

  • Patent number: 7854039
    Abstract: A cleaner having a handle assembly rotatable in all directions is disclosed, the handle assembly including a housing; a handle which is capable of being gripped by a user; a connection unit which connects the handle with the housing to rotate in all directions; and an elastic unit which elastically biases the handle to a neutral position. As the handle is capable of rotating in all directions, a user can clean a surface without feeling strain in his or her joints.

  • Patent number: 7823251
    Abstract: A surface-treating appliance in the form of a vacuum cleaner has a main body, a surface-treating head and a support assembly. The support assembly is moveable between a supporting position, in which it supports the main body, and a stored position, in which it lies substantially against the main body. The provision of a support assembly that lies substantially against the main body of the appliance when not needed improves the maneuverability and range of motion achievable by the appliance in use. The support assembly may be brought out of its supporting position by a user-depressible pedal, which makes the appliance user-friendly.

  • Patent number: 7805804
    Abstract: A steerable upright vacuum cleaner includes an upright section including a dirt collecting portion, a collar on which the upright section is mounted and base section to which the collar is attached. The upright section is mounted on the collar such that the upright section pivots around a first axis with respect to the collar. The base section is attached to the collar such that the collar pivots around a second axis with respect to the base section. The second axis is approximately perpendicular to the first axis. The base section includes a nozzle that communicates with the dirt collecting portion.

  • Patent number: 7725984
    Abstract: A bare floor cleaner for wet and dry bare floor surfaces comprises a base with wet and dry suction nozzles and a handle pivotally connected to the base. A diverter mounted in the working air conduit between each of the dry suction nozzle and the wet suction nozzle to a recovery tank is movable by movement of the handle between a dry suction position and a wet suction position for selectively at least partially blocking working air flow from the wet suction nozzle and the dry suction nozzle, respectively, to the recovery tank. A shut-off valve is mounted in the recovery tank to prevent fluid communication between a suction source and the recovery tank when the amount of liquid in the recovery tank reaches a first predetermined amount with the handle forward and a second predetermined amount with the handle rearward.

  • Patent number: 7607196
    Abstract: A vacuum cleaner includes a head for contacting the ground and a body which is pivotable relative to the head about a first axis of rotation and about a second axis of rotation. The body has a locking mechanism and the head has a reciprocal locking mechanism which are arranged such that the locking mechanism is engageable with the reciprocal locking mechanism so as to resist pivotal movement of the body relative to the head about the first axis of rotation. The locking mechanism is disengageable from the reciprocal locking mechanism to allow pivotal movement of the body relative to the head about the first axis of rotation. The vacuum cleaner also includes a stabilizer coupled to the head such that in use the stabilizer maintains contact with the ground when the body is rotated relative to the head about the first or second axis of rotation.
