ABSTRACT:
An induction liquid pump includes a power unit and a circulation unit that are oppositely mountable to a tank with a plurality of fixation units. The liquid pump power unit includes a power induction unit to produce a variable magnetic field. The submersible liquid pump circulation unit includes an impeller unit to agitate or induce liquid flow in response to the variable magnetic field. A magnetic scrubber includes a power unit and a pad unit. The scrubber power unit produces a variable magnetic field in response to supplied power. When the scrubber power unit is held against a first surface of a tank, the scrubber pad unit is held oppositely against a second surface of the tank. The scrubber pad unit moves in response to the variable magnetic field to scrub the second surface of the tank.
