摘要： 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.

摘要： This invention relates to a bagless vacuum cleaner, and most preferably a battery-powered vacuum cleaner. The vacuum cleaner may be a cylinder vacuum cleaner, an upright vacuum cleaner or a hand-held vacuum cleaner. The bagless vacuum cleaner has a dirt-collection chamber with an inlet and an outlet and a filter at its outlet. According to the invention the vacuum cleaner has an agitator to agitate the filter and dislodge dirt and dust which has adhered to the filter, whereby to extend the period before the filter becomes blocked.

摘要： A suction head for a vacuum cleaner comprises a hollow body including a pair of arms (1, 3) which diverge from a predetermined region of the body at an angle less than 180 degrees relative to each other. Each arm is formed with a channel (14) for the passage of air, the channel extending from the free end of the arm to the region of the body from which the arms diverge. 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) from the free end of the arm to the region of the body from which the arms diverge. A second continuous ground-engaging barrier (21) extends along the region of an inner edge (19) of the other of the arms (3) from the free end of the arm to the region from which the arms diverge. A gap (23) is formed between the first and second barriers (21) in the region from which the arms diverge for the passage of relatively large particles of debris into the suction head. The first and second barriers (21) are adapted to engage a flat ground surface along the entire length of the first and second barriers.

摘要： A vacuum cleaner is described, and in particular a battery-powered vacuum cleaner including a rotatable brush. The vacuum cleaner has a suction head adapted to be moved across a surface to be cleaned, the suction head having a leading end and a trailing end, the suction head having: a rotatable brush, the rotatable brush being located in a brush chamber at the leading end of the suction head, the brush chamber having an opening through which a part of the rotatable brush projects, the opening and the rotatable brush spanning substantially the full width of the suction head; suction means adapted to create a flow of air into the suction head during use; a dirt-collection chamber; a filter located downstream of the dirt-collection chamber; a primary air flow duct connecting the brush chamber to the dirt-collection chamber and through which air can flow into the dirt collection chamber during use, a secondary air flow duct connected to the dirt-collection chamber and through which air can flow into the dirt collection chamber during use, the secondary air flow duct comprising a length of hose terminating in an inlet nozzle.
