The base plate of a robotic or manually propelled tank or pool cleaning apparatus includes a transverse conduit positioned on the interior surface of the base plate and is in fluid communication with a source of pressurized water that is also located within the pool cleaner's housing, which pressurized water is discharged from the bottom or lower portion of the transverse conduit through a plurality of openings that extend along a line that is transverse to the longitudinal axis of the pool cleaner's direction of travel, to produce downwardly-directed water jets that are discharged through and below the base plate towards the surface of the pool or tank over which the pool cleaning apparatus is moving to dislodge and suspend dirt and debris that is then drawn into and retained by the pool cleaner's filter.
A base plate for a pool or tank cleaner, the cleaner including a housing, movable support means for contacting a surface of the pool or tank, a filter for capturing debris from water passing through the housing, a source of pressurized water and a pressurized water delivery conduit extending from the source of pressurized water, the base plate comprising:
The base plate of claim in which the longitudinal axes of at least a portion of the plurality of openings are angularly displaced from a vertical plane extending through the longitudinal axis of the transverse conduit.
A method of removing dirt and debris from the bottom surface of a pool or tank which comprises passing a self-propelled pool or tank cleaner over the bottom surface and discharging a plurality of water jets from a plurality of openings that are arrayed along a line that is generally transverse to the longitudinal axis of the pool or tank cleaner as defined by its direction of travel, wherein the dirt and debris is put into suspension in the water beneath a base plate the cleaner and drawn into a filter within the interior of the cleaner through at least one opening in the base plate.
