Abstract
A remote surface preparation device for preparing a remote surface, such as cleaning the inside surface of an aquarium tank from the outside is provided. The device includes a remotely actuated surface preparation assembly having a body with at least one magnetic element for coupling it for remote actuation to complimentary magnetic elements in a moving drive head disposed at some distance therefrom. The device includes an adjustment mechanism which can vary the magnitude of the magnetic forces coupling the remote surface preparation assembly to the device, even during device operation.

A surface preparation device for preparing material having a remote surface and a spaced apart proximate surface comprising:
- a remote surface preparation assembly having a body with a coupling element and a first end for contacting the remote surface for preparing the first surface;
- a base having one or more support surfaces for contacting the proximate surface and a view-through portion;
- a drive head including an elongated member having opposite ends and a centrally disposed motor connection point, the elongated member having a coupling element at each of the opposite ends providing a magnetic attractive force for attracting the remote surface preparation assembly coupling element thereby coupling the remote surface preparation assembly to the drive head for remote actuation, wherein at least one of the drive head coupling element and the remote surface preparation assembly coupling element is a magnet;
- a body housing movably connected to the base and having a handle portion for gripping the surface preparation device during operation;
- and
- a motor disposed within the body housing and connected to the motor connection point rotating the elongated drive head within the base thereby enabling a user to see at least one of the proximate surface and the remote surface through the view-through portion and the rotating elongated drive head during operation.
A power operated surface preparation tool for preparing material having a remote surface and an oppositely disposed proximate surface spaced apart from the remote surface comprising:
- a remote surface preparation assembly having an application surface, for preparing the remote surface, the assembly having at least one magnetic element;
- a body having a drive head disposed at a first end, the drive head having at least one drive head magnetic element providing a magnetic coupling force for attracting the surface cleaning assembly magnetic element to couple the surface cleaning assembly to the drive head for remote actuation, and the body housing having a handle portion for gripping the device during operation;
- a motor mounted within the body housing and connected to the drive head for moving the at least one drive head magnetic element along a drive plane thereby moving the remote surface preparation assembly via the magnetic coupling force;
- and
- a base having one or more support surfaces disposed in a support plane for contacting the proximate surface and an aperture receiving the body housing therethrough, the base movably connected to the body housing for movement relative thereto for varying the distance between the drive plane and the support plane.
A power tool for cleaning an interior surface of an aquarium comprising:
- a remote surface cleaning assembly having a body with at least one magnetic element connected thereto and a first end for contacting the interior surface of the aquarium;
- a body housing having a drive head including an elongated member with opposite ends and a centrally disposed motor connection point disposed at a first end of the housing, the drive head having a magnetic element disposed at the opposite ends providing a magnetic coupling force for attracting the surface cleaning assembly magnetic element to couple the surface cleaning assembly to the drive head for remote actuation;
- a motor mounted within the body housing and removably connected to the drive head for rotating the drive head and drive head magnetic element thereby moving the remote surface cleaning assembly via the magnetic coupling force;
- and
- a base connected to the body housing, the base having a support end for contacting an exterior surface of the aquarium and a view-through portion enabling a user to see the interior surface through the view-through portion and the rotating elongated drive head member during operation, the base further comprising an adjustment surface cooperating with the body housing for fixing the base to the body housing at a plurality of different positions, each position providing a different distance between the base support end and the drive head magnetic element.
