    Abstract: A hand vacuum cleaner may have a first stage cyclone having a first stage cyclone chamber and a second stage cyclone downstream from the first stage cyclone and at least substantially nested in the first stage cyclone. A screen is positioned laterally outwardly from the second stage cyclone and defines a passage positioned between an inner side of the screen and the outer wall of the second stage cyclone. A directing member is located in the passage, the directing member having, in the rotational direction, a directing surface facing towards the flow of air in the passage, the directing surface extending from an upstream end located in the passage and a downstream end located proximate the second stage cyclone air inlet port wherein the directing surface extends generally linearly.

    Abstract: A hand vacuum cleaner may have a first stage cyclone having a first stage cyclone chamber, a first stage cyclone air inlet, a first stage cyclone air outlet and a first stage longitudinal cyclone axis about which the air rotates in the first stage cyclone chamber. A second stage cyclone may be downstream from the first stage cyclone and may be at least substantially nested in the first stage cyclone. The second stage cyclone may have a second stage cyclone chamber, a plurality of second stage cyclone air inlets, a second stage cyclone air outlet and a second stage longitudinal cyclone axis about which the air rotates in the second stage cyclone chamber. A length of the second stage cyclone chamber may be shorter than a length of the first stage cyclone chamber.

    Abstract: A cyclone assembly includes a first cyclonic cleaning stage. The first cyclonic cleaning stage includes at least one first stage cyclone having a first stage cyclone chamber. Each first stage cyclone chamber has a height extending between a first stage cyclone chamber air inlet and a first stage cyclone dirt outlet. The cyclone assembly also includes a second cyclonic cleaning stage downstream from the first cyclonic cleaning stage. The second cyclonic cleaning stage includes a plurality of second stage cyclones in parallel. Each of the plurality of second stage cyclones has a height extending between a second stage cyclone chamber air inlet and a second stage cyclone dirt outlet. The second cyclonic cleaning stage has a larger number of second stage cyclones than the first cyclonic cleaning stage, and the height of each second stage cyclone chamber is greater than the height of each first stage cyclone chamber.
