  • Patent number: 11297988
    Abstract: This invention relates to a bagged vacuum cleaner, i.e. to a vacuum cleaner in which dirt and debris is collected in a disposable bag. The vacuum cleaner (10) has a body (12), the body having a dirt-collection chamber (26), a motor (14) and an impeller (16). The body also has an inlet duct (30) upstream of the dirt-collection chamber, the inlet duct being connected to an inlet tube (36) adapted to fit to an opening of the disposable bag. A wall (40) of the inlet duct adjacent to the inlet tube (36) is transparent so that a user can look through the wall and into the inlet tube to observe whether or not the bag is full.

  • Publication number: 20210307572
    Abstract: Battery-powered vacuum cleaner (10), in particular having multiple modes of operation. The battery-powered vacuum cleaner has a body (12) with a battery (14), a motor (16), an impeller (18) and a dirt-collection chamber (20). The body has a bottom wall with an opening (34) through which air can pass into the body. A rotatable brush (36) is mounted adjacent to the opening (34). The body has a first side (44) and a second side (46), the opening spanning a large proportion of the body between the first and second sides. The battery (14) is located at the first side (44) and the motor (16) is located at the second side (46), with the dirt-collection chamber (20) between the battery and the motor.

  • Publication number: 20210298242
    Abstract: The invention relates to a branch cutter (10), namely a motor-powered tool having a circular saw blade used for cutting tree branches and the like. The periphery of the saw blade is at least partially covered by a protective housing (24), the housing having a first opening (52) to expose a first portion of the periphery of the saw blade, and a second opening (54) to expose a second portion of the periphery of the saw blade. The provision of two housing openings exposing two portions of the periphery of the saw blade increases the utility and ease of use of the branch cutter.

  • Patent number: 9943199
    Abstract: This invention relates to a hand-held vacuum cleaner (10). The vacuum cleaner is expected to have particular utility for cleaning locations which are difficult to reach with a conventional vacuum cleaner. The vacuum cleaner (10) has a body (12) with a substantially planar base (22) upon which the vacuum cleaner can rest when not in use, the body having a carrying handle (20), a motor (14) and an impeller (16) located within the body, the vacuum cleaner also having a collector (26, 126) and a battery pack (18), the battery pack providing at least a part of the base (22). The motor and the battery pack are located between the base and the collector so as to lower the center of gravity and make the vacuum cleaner more comfortable for use, especially over long periods. Ideally, the center of gravity is close to the carrying handle, and between the carrying handle and the nozzle so that the vacuum cleaner is slightly “nose heavy”.

  • Patent number: 9560944
    Abstract: This invention relates to a vacuum cleaner (10), and in particular a vacuum cleaner (10) having a rotatable brush (24). The vacuum cleaner (10) has a travelling head (12) adapted to be moved across a surface to be cleaned, the travelling head (12) having a leading end (28) and a trailing end. The travelling head (12) has a rotatable brush (24), the rotatable brush (34) being located in a brush chamber (23) at the leading end of the travelling head (12), the brush chamber (34) having an opening (26) through which a part of the rotatable brush (24) projects, the opening (26) and the rotatable brush (24) spanning substantially the full width of the travelling head (12). The travelling head (12) also has an impeller (46), and a motor (34) for driving the rotatable brush (34) and the impeller (46).

  • Patent number: 7802343
    Abstract: A suction head for a vacuum cleaner comprises a hollow body including a pair of arms (1, 3) which diverge from predetermined region of the body at an acute angle. Each arm is formed with a channel (14) for the passage of air. An outlet opening (5) is located in the region of the body from which the arms diverge for the passage of air to a vacuum cleaner. A first continuous ground-engaging barrier (21) extends along the region of an inner edge (19) of one of the arms (1). A second continuous ground-engaging barrier (21) extends along the region of an inner edge (19) of the other of the arms (3). A gap (23) is formed between the first and second barriers (21) for the passage of relatively large particles of debris into the suction head.

  • Publication number: 20090300873
    Abstract: A surface cleaning apparatus comprises a debris retrieval body (3), and a first collection means (47) and a second collection means (13) provided within the debris retrieval body for accumulating debris from a surface to be cleaned. A rotatable elongate brush arrangement (27) is provided within the debris retrieval body and is adapted to retrieve a first portion of debris from the surface to be cleaned and to direct the first portion of the debris along a first pathway (311) into the first collection means (47). A first inlet aperture (75) is provided in the debris retrieval body for the passage along a second pathway (315), independent of the first pathway, of a second portion of debris from the surface to be cleaned to the second collection means, the first inlet aperture communicating with a first means for creating suction (17).
