Abstract
A hand held extendable wand containing a battery power supply and electric motor is controllable and directable by a pistol grip with switches for on-off and speed on one end. A shaft from the motor extends beyond the wand on the other end. Cleaning brushes attach to the motor shaft in one case and a reciprocating motion conversion block containing a shaped brush is attached to the wand housing and motor shaft in another case. The wand contains an adjustable extension to vary the length of reach of the brush.
Claims6
A battery powered tile cleaning apparatus comprising:
- a tubular wand having two ends;
- a means for grasping and directing on one of said ends of said wand;
- said means for grasping and directing comprising a pistol grip;
- an opening on the other of said ends of the wand;
- a tubular wand extension having two ends and being concentrically located within and telescopingly connected to the wand;
- the wand extension being axially translatable through the opening of the wand into extended and retracted positions;
- motor means, comprising a direct current electric motor, positioned within the wand extension at the end of the wand extension distal from the means for grasping and directing;
- a shaft means, attached to the motor means, extending beyond the end of the wand extension distal from the means for grasping and directing;
- means for activating said motor means, said means for activating positioned in the wand and comprising at least one battery;
- means for connecting the activating means and the motor means, said motor means comprising:
- an on-off switch;
- and
- a slow-fast switch connected to the on-off switch;
- means for cleaning operatively attached to the shaft means;
- means for releasably locking the wand extension in the extended and retracted positions;
- means, engaging said shaft means, for causing reciprocating motion of the means for cleaning;
- a spring biased ball mounted in the shaft means for operatively connecting the means for causing reciprocating motion to the shaft means.
