    摘要： A portable vacuum cleaner has an air treatment chamber, a pre-motor filter positioned downstream from the air treatment chamber, a body including a suction motor, the suction motor is positioned in the air flow passage downstream from the pre-motor filter. A handle is provided on the body. The pre-motor filter has a first end, an axially spaced apart second end, a sidewall extends between the first end of the pre-motor filter and the axially spaced apart second end, wherein the sidewall comprises a filter material surrounding an open interior providing a filtered air flow path, the axially spaced apart second end is open whereby, after passing through the sidewall, air enters the filtered air flow path and passes through the open axially spaced apart second end. The longitudinal air treatment chamber axis and the motor axis extend in the same direction and each extend through the open interior.

    摘要： A vacuuming broom assembly includes a vacuum pack that is wearable on a user's back. The vacuum pack has an intake for urging air inwardly therein when the vacuum pack is turned on and a suction hose is fluidly coupled to the intake. A broom is provided that has a head and a handle. A suction manifold is coupled to the broom and the suction manifold has a pair of inlet ports and an exhaust port. The suction hose is fluidly coupled to the exhaust port such that the suction manifold is in fluid communication with the vacuum unit. Each of the inlet ports is aligned with the head of the broom for sucking up debris that is produced from sweeping. In this way the vacuum unit reduces airborne particles produced from sweeping.
