The Mercury 15-inch Lo-Boy Floor Machine is a low-speed (175 RPM) commercial rotary built for facility managers, custodial crews, and floor-care contractors who need one machine to strip, scrub, buff, and bonnet-clean hard floors and carpet. Its low-profile chassis slides under counters, toe-kicks, and fixtures where taller buffers cannot reach, and the heavy all-metal frame adds the down-pressure that makes stripping old finish and deep scrubbing faster.
Built for these jobs
- Stripping wax and finish - the slow 175 RPM speed and high-torque transmission drive black strip pads through built-up floor finish on VCT, terrazzo, and concrete.
- Daily and restorative scrubbing - run a green or blue pad (or a 13-inch rotary brush) to lift embedded soil from tile, grout, and sealed concrete.
- Spray buffing and burnishing prep - restore gloss between recoats on maintained finishes.
- Carpet shampooing and bonnet cleaning - fit a pad driver and bonnet for interim carpet maintenance in offices, hallways, and lobbies.
- Tight, low-clearance areas - the Lo-Boy profile reaches under restroom partitions, lab benches, and retail fixtures.
Why the low-speed design works
At 175 RPM the brush or pad stays in firm, sustained contact with the floor, so the machine does aggressive work (stripping, heavy scrubbing) that high-speed burnishers cannot. The precision-balanced 1.5 HP 66-frame motor and triple-planetary high-torque transmission handle demanding jobs without bogging down, and the all-metal polished chassis adds weight for a faster, brighter result. Match your accessory to the floor: use a rotary brush 2 inches smaller than the machine, or a pad with pad driver and riser 1 inch smaller than the machine.

Frequently Asked Questions
Is the Mercury L-15E a low-speed or high-speed floor machine?
It is a low-speed machine running at 175 RPM. Low-speed rotaries are the right tool for stripping floor finish, heavy scrubbing, spray buffing, and bonnet cleaning, because the slow speed keeps the pad in firm contact with the floor. High-speed burnishers (1,000+ RPM) are used only for polishing maintained finishes.
Do I need a brush or a pad driver?
It depends on the job. Use a 13-inch rotary brush for scrubbing tile, grout, and concrete. Use a pad driver with riser and a floor pad for stripping, buffing, and bonnet cleaning - black pads for stripping, green or blue for scrubbing, and white or red for polishing. The brush, pad driver, and riser are ordered separately.
What size pad and brush fit the 15-inch machine?
Choose a rotary brush 2 inches smaller than the machine size (13-inch) or a pad with pad driver and riser 1 inch smaller (14-inch). Do not use a brush with riser at the same time as a pad driver with riser.
Can the Lo-Boy strip wax and old floor finish?
Yes. The combination of 175 RPM, the high-torque triple-planetary transmission, and the heavy all-metal chassis lets the L-15E drive black strip pads through built-up finish on VCT, terrazzo, and similar hard floors. Pair it with a wet/dry vacuum or auto-scrubber to recover the slurry.
Why is it called a Lo-Boy?
The Lo-Boy has a low-profile body that fits under counters, restroom partitions, lab benches, and retail fixtures that block taller floor machines, so you can clean right up to and under those obstructions.
