摘要： The invention relates to dirt separator module comprising a dirt-separation housing having an inlet and an outlet opening and defining a cyclonic airflow separator, and a suction source fluidly connected with the dirt-separation housing. A separator plate and a cylindrical wall of the dirt-separation housing form a toroidal cyclonic airflow chamber in the dirt-separator for aiding in the separation of dirt from a suction airstream developed by the suction source. The separator plate has an outer diameter smaller than the inner diameter of the cylindrical wall of the dirt-separation housing, creating a gap between the outer edge of the separator plate and the inner wall of the dirt tank. A further embodiment includes dual cyclonic separators fluidly connected through a filter assembly. A further embodiment includes a cyclonic separator in the form of a tangential helical ramp.

摘要： The invention relates to a cyclonic dirt separator comprising a dirt-collection assembly including a dirt tank having an inlet aperture and an outlet aperture, a cyclonic separator, at least one filter element, and a suction source fluidly connected with the dirt collection assembly. In one embodiment, the cyclonic dirt separator includes a separator plate cooperating with the housing to form a toroidal region of the dirt tank for aiding in the separation of dirt from a suction airstream developed by the suction source. The separator plate has an outer diameter smaller than the inner diameter of the dirt tank, creating a gap between the outer edge of the separator plate and the inner wall of the dirt tank. A further embodiment includes fins projecting from a sidewall of the dirt tank, and fingers projecting from a bottom wall of the dirt tank, to reduce re-entrainment of dirt particles.

摘要： A multi-use vacuum cleaner has a central body which houses a motor, air impeller, battery and a dirt collection chamber. One end of the central body has a face inclined to the longitudinal axis of the central body with a rectangular inlet orifice into which the coupling nozzle of a floor and carpet pickup head can be frictionally inserted. The other end of the body has an integral, axially protruding extension providing a primary handle for manipulating the body as a hand held cushion and upholstery cleaner. The primary handle has means for detachably mounting an extension handle permitting the unit to be used as a standard upright vacuum cleaner or for vacuuming overhead and other areas which would be otherwise inaccessible.

摘要： A floor sweeper has a pair of brush rollers, each sweeping into its own dust pan. Each brush roller has different debris pickup characteristics, with one brush roller tending to be more efficient in picking up large debris and the other roller tending to be more efficient in picking up smaller debris. The illustrated embodiment discloses a front brush roller of the off-center tufted type which rotates continuously toward its respective pan during reciprocal sweeper translation, with a relatively high free-wheeling rotation in one direction of sweeper translation. The rear brush roller is of the wire twist type and also rotates continuously toward its pan during reciprocal sweeper translation, but with relatively low rolling rotation in one direction of sweeper movement.
