Abstract
A docking station for a robotic surface cleaning apparatus has a momentum separator. The momentum separator has an upper wall, a lower wall and a first sidewall extending between the upper and lower walls. The first sidewall comprises a side screen and an end wall is spaced from and faces the side screen whereby an up flow chamber is positioned between the end wall and the side screen. The upper wall also comprises an upper screen and an upper end wall is spaced from and faces the upper screen wherein an upper air flow chamber is positioned between the upper end wall and the upper screen.
Claims19
A vacuum cleaner or a docking station for a vacuum cleaner comprising:
- a) an air flow path extending from an air inlet of the vacuum cleaner or a docking station for a vacuum cleaner to an air outlet of the vacuum cleaner or a docking station for a vacuum cleaner;
- and,
- b) a momentum separator positioned in the air flow path wherein, when the vacuum cleaner or a docking station for a vacuum cleaner is positioned on a horizontal surface in an in use position, the momentum separator has an upper wall, a lower wall and a first sidewall extending between the upper and lower walls,
- wherein the first sidewall comprises a side screen and an end wall is spaced from and faces the side screen whereby an up flow chamber is positioned between the end wall and the side screen, and
- wherein the upper wall also comprises an upper screen and an upper end wall is spaced from and faces the upper screen wherein an side-flow chamber is positioned between the upper end wall and the upper screen
- wherein the side-flow chamber is isolated from the up flow chamber along a length of the up flow chamber.
