Abstract
A hand vacuum cleaner is provided with a wand mounted to the dirty fluid inlet of the hand vacuum cleaner and the wand has a distal inlet that is mounted on a surface cleaning head. The hand vacuum cleaner has a cyclonic cleaning stage. The dirty fluid inlet has a passage with a passage axis and the cyclonic cleaning stage has a longitudinal axis. The fluid flow motor is displaced from the passage axis in a direction parallel to the longitudinal axis.
Claims21
-27. (canceled)
A hand vacuum cleaner comprising:
- a) a first cyclonic cleaning stage comprising a first cyclone having an openable bottom;
- b) a second cyclonic cleaning stage located downstream from the first cyclonic cleaning stage and comprising a plurality of cyclones in parallel, a central longitudinal axis and an outer perimeter extending around the central longitudinal axis, each of the plurality of cyclones having a cyclone chamber;
- c) a pre-motor filter positioned downstream from the second cyclonic cleaning stage and having filter material located within the outer perimeter of the second cyclonic cleaning stage;
- d) a manifold positioned upstream of the pre-motor filter and downstream of the second cyclonic cleaning stage, the manifold is located within the outer perimeter of the second cyclonic cleaning stage;
- and,
- e) a fluid flow motor that is downstream from the pre-motor filter.
