Frequently asked questions

Should I run a 17-inch or 20-inch apron?

A 17-inch pad is the most versatile - it tracks well in occupied spaces, around restroom partitions and tight aisles. A 20-inch or 21-inch pad covers more square footage per pass and is a better choice for open showrooms, gym floors and large warehouse breakrooms.

What is the difference between 175 RPM and 300 RPM?

A 175 RPM single-speed machine like this BOSS is the standard for stripping and scrubbing - the slower head speed lets aggressive pads bite into floor finish and embedded soil. A 300 RPM or dual-speed machine is meant for spray buffing and bonnet polishing to bring up a faster shine on already maintained finish.

Can I use this machine wet for floor stripping?

Yes. Apply stripping solution to the floor with a mop or pump-up sprayer, let it dwell for 10 to 15 minutes, then agitate with an aggressive black or brown stripping pad. Pick the residue up with a wet/dry vacuum or auto-scrubber before applying new finish.

Do I need the Unicorn weight kit?

The Unicorn weight kit is optional - it adds extra downforce for heavy strip jobs on thick wax buildup or aggressive scrubbing. For routine maintenance scrubbing and bonnet buffing, the machine has enough head weight on its own.
