US Patent 7378026 Drill motor operated portable water-tolerant suction cleaner

The present invention describes an apparatus and teaches a method for removing particulate matter from a plurality of vessels. Examples of these vessels include aquariums, spas, fountains and pools. An ordinary hand held power drill motor is connected via a drill motor pump to a pick-up head containing a pair of hoses. Upon activation, a first hose applies suction to the pick-up head drawing both water and particulate into a chamber. The water continues through to a pump mounted in a housing, through the pump and out the discharge hose while the particulate is trapped within the chamber by a filter for later removal.
