  • Patent number: 9901229
    Abstract: An all in the head surface cleaning apparatus includes a surface cleaning head having a lower surface having a dirty air inlet. The surface cleaning head may include a brush motor drivingly connected to a movable brushing member having a brush motor axis. The surface cleaning head may include a cyclone comprising a cyclone chamber having a longitudinal cyclone axis. The surface cleaning head may include a suction motor having a first end, a second end and a suction motor axis extending between the first and second ends. The surface cleaning head may include a bleed valve having an inlet end, an outlet end and a body extending between the inlet and outlet ends. The body may have a bleed valve axis. The bleed valve axis may be generally parallel to at least one of the cyclone chamber axis, the suction motor axis and the brush motor axis.

  • Patent number: 9883781
    Abstract: An all in the head surface cleaning apparatus may have a surface cleaning head including a front end, a rear end, first and second laterally opposed sidewalls. The surface cleaning head may include a cyclone assembly comprising a cyclone chamber and a dirt collection chamber. The cyclone chamber may have a longitudinal cyclone axis, a cyclone assembly air inlet port and a cyclone assembly air outlet port. The cyclone assembly may be moveable from a cleaning position to a cyclone assembly removal position. The surface cleaning head may include a biasing member biasing the cyclone assembly away from the cleaning position, and a suction motor having a suction motor air inlet and a suction motor axis. The apparatus may include an upper portion moveably mounted to the surface cleaning head between a storage position and a floor cleaning position, the upper portion comprising a drive handle.

  • Patent number: 9795264
    Abstract: A surface cleaning head has a cyclone assembly with a cyclone assembly air inlet port and a cyclone assembly air outlet port, a first air flow path extending from a dirty air inlet to the cyclone assembly air inlet port, and a second air flow path extending from the cyclone assembly air outlet port to a suction motor air inlet. The cyclone assembly moveable from a cleaning position in which the cyclone assembly air inlet port is in communication with an outlet port of the first air flow path and cyclone assembly air outlet port is in communication with an inlet port of the second air flow path to a removal position in which the cyclone assembly air inlet port is spaced from the outlet port of the first air flow path and cyclone assembly air outlet port is spaced from the inlet port of the second air flow path.
