Mercury Hercules, BOSS, and Lo-Boy Floor Machines

The Low-Speed Machine Lines at 175 RPM

Mercury's low-speed floor machines run at 175 RPM, the range that gives you torque for scrubbing, stripping, and spray buffing on VCT, terrazzo, and sealed concrete. The lines differ in build. Hercules floor machines (H-17E, H-19E, H-20E, H-21E) are the heavy end at roughly 106 to 108 pounds, where machine weight does the work on stripping. Lo-Boy machines (L-15E through L-21E) sit lower and lighter at 96 to 105 pounds for clearance under fixtures and easier handling. BOSS covers dual-speed work: the BOSS-1 runs 175 RPM, while the BOSS-2 switches between 175 and 300 RPM with aprons from 13 to 21 inches, and the BMT Multi-Tasker offers the same two speeds. The Corsair rounds out the range as a 3-speed machine.

Ultra D.C. Burnishers and Hercules Floor Sanders

Burnishing is a separate job from buffing, and Mercury's Ultra D.C. line handles it across three speeds: 1,170 RPM, 1,500 RPM, and 2,000 RPM, in 19, 20, and 21-inch widths. Higher speed produces more gloss but demands a finish that can take the heat, so match the RPM to your coating rather than defaulting to the fastest machine. Mercury also builds Hercules sealed-motor floor sanders (H-17S, H-19S, H-20S, H-21S) at 175 RPM on a 1.5 HP sealed motor, a third category people often miss when shopping the brand. Sanding kits, dust skirts, and sandpaper drivers are made for them.

Pads, Drivers, and What Mercury Does Not Make

Mercury machines take standard 17, 20, and 21-inch pads and pad drivers. Pad color signals aggressiveness: black strips, red and brown scrub heavy, blue maintains, and white polishes. Natural hair pads suit finish work on sensitive surfaces. One clarification worth making before you buy: these are buffers, burnishers, and sanders. They do not scrub and recover dirty water in one pass. If that is what you need, you are shopping for a walk-behind floor scrubber, which is a different machine entirely.

Frequently Asked Questions

What is the difference between a Mercury buffer and a burnisher?
A Mercury low-speed buffer runs at 175 RPM for scrubbing, stripping, and spray-buff on VCT, terrazzo, and sealed concrete. A high-speed Ultra D.C. burnisher runs at 1,170 to 2,000 RPM to bring VCT and stone to a high-gloss finish. Use the buffer for cleaning and prep, the burnisher for final shine on maintained floors.
What cleaning-path width do Mercury machines offer?
Mercury low-speed floor machines take aprons from 13 to 21 inches, so the Hercules, BOSS, and Lo-Boy lines cover everything from tight restrooms to open commercial floors. Ultra D.C. burnishers come in 19, 20, and 21-inch widths. Pick the width by your largest routine floor area.
Which floor pad do I use with a Mercury machine?
Pad color indicates aggressiveness: black for stripping, red or brown for heavy scrubbing, blue for maintenance scrubbing, and white for polishing and spray-buff. Mercury machines use standard 17, 20, and 21-inch pads and pad drivers, so generic pads from any maker fit.
Do Mercury machines scrub and recover water?
No. Mercury builds buffers and burnishers that work on dry or lightly dampened floors to strip, polish, or maintain finish. If you need to scrub and vacuum up dirty water in one pass, that is a walk-behind floor scrubber, a separate category.
