Abstract:
1. A pool cleaning apparatus comprising: a housing; a baseplate extending along a bottom portion of the housing and adapted for interfacing with an underwater surface; at least one intake port formed in the baseplate; pump means for drawing water from beneath the baseplate and through the at least one intake port; a plurality of directional cleaning water jet outlets located beneath the baseplate, said plurality of directional cleaning water jet outlets being orientated in a direction toward said surface and the at least one intake port for discharging a pressurized water jet stream beneath the baseplate, said pump means further providing said pressurized water jet streams to said directional cleaning water jet outlets; a filter coupled between said at least one intake port and pump means for filtering said dirt and debris from said drawn water; and switching means coupled to said cleaning water jet outlets for selectively activating and deactivating each water jet outlet in response to a change in direction of movement of said cleaning apparatus, such that the directional orientation of the active water jet outlets discharging water at the surface is at least partially upstream of the at least one intake port admitting water, wherein said at least one intake port draws in dirt and debris lifted from the surface that is contacted by the discharging water jet streams.
