  • Patent number: 10499779
    Abstract: A vacuum cleaner comprising: a housing; a motor fan assembly arranged to generate an air flow; a dirt container in fluid communication with a dirty air inlet and the motor fan assembly; a moveable dirt compactor mounted in the dirt container and moveable between a stowed position and a dirt compacting position wherein the moveable dirt compactor is closer to one end of the dirt container in the dirt compacting position than in the stowed position, wherein the movable dirt compactor is shaped so as to allow dirt within the dirt container located on one side of the dirt compactor to pass to the other side of the dirt compactor; and a detector switch coupled to the moveable dirt compactor, the detector switch configured to open an electrical circuit and interrupt power supplied to the motor fan assembly when the moveable dirt compactor moves towards the dirt compacting position and urges dirt towards the one end of the dirt container.

  • Patent number: 8756905
    Abstract: A mower comprising an edge guide located adjacent an outer surface of a side wall and at least partially surrounding an opening. The edge guide comprises an inlet and is arranged to guide vegetation towards the opening. The edge guide defines a channel having at least one direction change between the inlet and the opening such that there is no line of sight between the inlet and the cutter element. By providing an edge guide having a convoluted path or channel, an opening in the side wall of the cutter housing can extend vertically up to the plane of the cutter element while still providing a radially-enclosed cutter element as required by safety regulations. Therefore, edge-located vegetation can be fed to the cutter in a more upright configuration for improved cutting.
