The Mercury Hercules H-15E is a 15-inch commercial floor machine built for daily janitorial prep work - stripping, scrubbing, bonnet cleaning, and pad-driver finish refresh on VCT, hard surface, and low-pile commercial carpet. 175 RPM, 1.5 HP A/C motor, all-metal construction, and Mercury's 5-year motor/transmission/chassis warranty - the 'Best Warranty on the Planet' that defines the Hercules line.
Why a 175 RPM Hercules is the workhorse of a floor program
Working floor-care contractors and building service managers consistently recommend the 175 RPM / 15-inch class as the right first machine for a commercial floor program. The reason: this speed and footprint covers strip, scrub, bonnet, and pad-driver work without compromise. Higher-speed burnishers put the gloss on, but they do not strip or scrub. The Hercules does the heavy work; a burnisher finishes the shine. Building service contractors in r/janitorial regularly call this combination the right two-machine investment for taking on commercial floor maintenance contracts.
Use cases
- VCT strip-and-recoat - 175 RPM at 15 inches lets aggressive stripper do the work without scorching the floor.
- Daily auto-scrub maintenance - paired with the right pad, runs neutral cleaner over corridor traffic to refresh finish before burnishing.
- Bonnet cleaning of low-pile commercial carpet - 14-inch pad driver with bonnet pad refreshes hospitality and corporate carpet between hot-water extractions.
- Concrete densifier and polishing prep - aggressive brushes with diamond-impregnated pads for concrete polishing programs.
- Restoration and grout-line scrubbing - swap to a 13-inch brush for tile and grout deep-clean work.

Frequently asked questions
What is a 15-inch 175 RPM floor machine used for?
The 175 RPM / 15-inch class is the all-around janitorial floor machine - stripping, scrubbing, bonnet cleaning, and pad-driver work on VCT, hard surface, and low-pile commercial carpet. 175 RPM is the speed that lets aggressive chemicals strip a finish without burning the floor, and the 15-inch pad covers ground fast enough for daily building maintenance routes.
What is the difference between a 175 RPM machine and a higher-speed burnisher?
175 RPM is the workhorse speed for prep work - strip, scrub, deep-clean. Burnishers spin at 1500-3000 RPM and are used to put the gloss on after a finish has been applied and cured. You need both for a complete floor program: the H-15E for prep and scrub, a burnisher for the finish shine.
How heavy is the H-15E?
Approximately 105 pounds in the 15-inch chassis - heavy enough that the machine does the work and you guide it. Weight is a feature, not a bug, on a floor machine: it puts the chemistry and pad into the floor instead of skipping across the top. Plan on training new operators on weight handling and counterbalance technique before turning them loose on customer floors.
What size pad driver and brush does it use?
The H-15E uses a 14-inch pad driver with riser and a 13-inch rotary brush. Standard 14-inch floor pads (strip, scrub, polish, white) all fit. Pad drivers and brushes for this machine are widely available; we stock them in-house.
What is the warranty?
Mercury calls it 'Best Warranty on the Planet' - 5 years on motor, transmission, and chassis. That is the core sales pitch for the Hercules line and what sets it apart from the entry-level commercial floor machines that come with 1-year warranties and aluminum housings.
