## Abstract

A method for treating flooring not designed for sanding and having a multi-layer wax finish reduces the frequency of stripping the wax layers down to the flooring and recoating the flooring in carrying out periodic maintenance on the flooring. A mobile floor treating machine includes at least one rotating brush which is driven at a first circular speed x for cleaning the flooring and is driven at a second circular speed y for removing the two uppermost layers of wax, where y≧2x. The top remaining wax layer is then cleaned with the brush operating at the original circular speed x. Two layers of wax are then sequentially applied to the top remaining wax layer in replacing the two removed layers of wax on the floor and restoring the flooring to its original finish. The brush may be operated at 800-1500 RPM for burnishing and polishing.

## Claims

### Claim 1

A method for treating floors having a finish of plural layers of wax deposited thereon, where the floor is cleaned by a mobile floor treating machine having at least one rotating brush or a rotating pad driven at a first circular speed x for cleaning the floor, said method comprising the steps of:
removing the uppermost layers of wax from the floor by means of the rotating brush or pad operating at a second circular speed of y, where y≧2x;
cleaning the top remaining layer of wax by means of the rotating brush or pad operating at the first circular speed of x; and
sequentially depositing layers of wax on the top remaining layer of wax in restoring the layers of wax on the floor to the original number of layers and restoring the floor to its original finish.

### Claim 2 (depends on 1)

The method of claim 1 wherein the floor is comprised of vinyl.

### Claim 3 (depends on 1)

The method of claim 1 wherein the step of cleaning the top remaining layer of wax includes applying water to the top remaining layer while moving the rotating brush or pad over the top remaining layer at a circular speed of 180 RPM and rinsing the water from the top remaining layer of wax.

### Claim 4 (depends on 1)

The method of claim 1 wherein the original finish comprises approximately seven layers of wax.

### Claim 5

A method for treating floors having a finish of plural layers of wax deposited thereon, where the floor is cleaned by a mobile floor treating machine having at least one rotating brush or a rotating pad driven at a first circular speed x for cleaning the floor, said method comprising the steps of:
removing the uppermost layers of wax from the floor by means of the rotating brush or pad operating at a second circular speed of y, where y≧2x;
cleaning the top remaining layer of wax by means of the rotating brush or pad operating at the first circular speed of x; and
sequentially depositing layers on the top remaining layer of wax in restoring the layers of wax on the floor to the original number of layers and restoring the floor to its original finish;
wherein x is approximately 180 RPM and y is approximately 400 RPM.
