  • Patent number: 8966708
    Abstract: A surface-treating appliance includes a main body, a surface-treating head and a support assembly. The support assembly is moveable out of a supporting position in which it supports the main body by a user performing a plurality of steps—for example, by depressing a pedal, then tilting the main body by pulling the handle. This arrangement reduces the likelihood of accidental release of the support assembly from its supporting position. For example, if the user depresses the pedal alone, or only pulls on the handle, the support assembly remains in its supporting position.

    Abstract: An upright vacuum cleaner for cleaning a surface includes a base unit with a brush motor and a brush roller drivable by the brush motor. An air conduit leads from the base unit to a dust collection container and includes an interface and a first section downstream of the interface. The first section includes a hose or a hose-and-wand assembly and is arranged externally on an upper body of the vacuum and is also securable to the upper body. A receiving structure on the upper body is configured to receive the first section and is removable from the receiving structure in a region of the interface so as to enable a vacuuming mode of operation that is independent of the base unit. A turning-off device is operable to turn off the brush motor when the first section is removed from the receiving structure.

  • Publication number: 20110265881
    Abstract: A vacuum cleaner with an automated diverter valve is described. The vacuum includes a handle, body, base, an automated diverter valve and air duct including two input ports. An automated diverter valve assembly at the junction of the dirty air intake within the base extends the air duct within the base and connects to the main air duct of the vacuum to the beater bar input and an attachment input. The automated diverter valve causes the air intake of the vacuum to be drawn from either the beater bar (floor) air input or the attachment input depending upon the position of the vacuum handle.

  • Patent number: 8042224
    Abstract: A cleaning appliance includes a main body, a handle assembly and a hose. The handle assembly includes a tube and a gripping portion fixedly attached thereto. The hose has one end attached to the main body. The tube is movable relative to the main body between a stored position in which at least a part of the tube lies within the hose and an extended position in which the gripping portion can be used to manipulate the cleaning appliance in use. By providing such an arrangement, the handle assembly and the hose can be stored compactly. When the user wishes to store the cleaning appliance, the tube can be retracted inside the hose for storage. When the tube is extended, the gripping portion is at a convenient height to be manipulated by a user.

  • Patent number: 8037570
    Abstract: A vacuum can include a housing having an inlet adapted to receive debris being vacuumed. A mounting bar can be fixedly coupled to the housing. A floor collector assembly can be rotatably disposed about a first axis defined by the mounting bar. The floor collector assembly can include a first debris-passing member coupled to the mounting bar, a second debris-passing member rotatably coupled to the first debris-passing member and a third debris-passing member removably coupled to the second debris-passing member. The first debris-passing member can define an opening. The floor collector assembly can be operable in a plurality of modes. In a first mode, the opening can be substantially perpendicular relative to a vacuumed surface. In a second mode, the second debris-passing member can be rotated relative to the first debris-passing member about a second axis such that the opening is at an acute angle relative to the vacuumed surface.

  • Patent number: 8032982
    Abstract: An upright vacuum cleaner having a suction path switching unit is provided that includes a cleaner body having and a body frame; a suction inlet body hinged to the body frame; a hose in fluid communication with the body frame and an extension pipe; and a suction path switching unit disposed on the body frame. The suction path has an operating duct elastically arranged on a suction path to be able to slide up and down. As the extension pipe is inserted into or withdrawn from a socket disposed on the body frame, the operating duct selectively diverts the suction path to a first suction path flowing from the suction inlet body to the dust collecting unit or a second suction path flowing from the extension pipe to the dust collecting unit.
