Abstract
Multiple floor treatment operations, such as burnishing, polishing, and scrubbing, may be performed using a single floor treatment machine having a motor, the speed of which is governed by a controller that responses to sensor signals indicative of the type of floor treatments pad or pads operatively coupled to the motor.
Claims10
A floor treating machine comprising:
- a. a chassis adapted to be moved along the floor;
- b. a first variable speed motor affixed to the chassis and adapted to be coupled to and rotate a first disk in a first direction, said first disk including a first predetermined number of magnets, said first predetermined number of magnets identifying the type of disk coupled to the first motor;
- c. a first Hall sensor adapted to generate a first voltage signal based on the first predetermined number of magnets of the first disk coupled to the first variable speed motor;
- and
- d. a controller coupled to the first Hall sensor and the first variable speed motor, said controller adapted to control the speed of the first variable speed motor based on said first voltage signal generated by the first Hall sensor.
