Mercury Floor Machines BOSS-1 Floor Machine – 1.5 HP, 175 RPM, Aprons 13"–21"

BOSS-1 Floor Machine — Single-Machine Coverage Across Five Pad Sizes with Triple-Planetary Transmission

The Mercury BOSS-1 replaces the need for multiple floor machines by accepting five apron sizes — 13", 15", 17", 19", and 21" — via a thumb-screw mount that swaps in under a minute. The 1.5 HP AC rectified motor and triple-planetary transmission deliver consistent torque at 175 RPM whether the operator is stripping a 21" apron on a heavily waxed VCT floor or buffing with a 13" pad in a tight restroom. At 90–107 lbs depending on apron selection, it stays planted without operator effort and handles the load variation between pad sizes without gear chatter or speed drop.

BOSS-1 Motor, Transmission, and Apron System

The triple-planetary gearbox and interchangeable apron system are the two features that determine whether this machine earns a permanent place in a cleaning contractor's trailer or gets replaced by a dedicated machine for each pad size.

• Five interchangeable apron sizes (13" to 21") on thumb-screw mount — swap pad size in under a minute; no tools, no separate machines for corridor scrubbing vs. open-floor buffing
• 1.5 HP AC rectified motor at 175 RPM — enough torque for strip jobs on heavy wax buildup without bogging down; consistent speed across all five apron sizes via the planetary gearbox
• Triple-planetary transmission — distributes load across three gear sets, reducing wear per gear and extending transmission life under heavy daily use in commercial environments
• Polished aluminum chassis with universal clutch brush drive — aluminum resists rust in wet scrubbing applications; the universal clutch engages and disengages the pad without stopping the motor
• 50 ft, 14/3-gauge safety power cord — reaches from a single outlet across most commercial restrooms, corridors, and classrooms without extension cords; 14/3 gauge handles the 1.5 HP motor draw safely
• Non-conductive dual triggers and adjustable 48" handle — interlock switch prevents accidental starts; 48" handle height suits operators from 5'2" to 6'4" without stooping

BOSS-1 Applications and Environments

Commercial cleaning contractors working across multiple account types — schools, offices, hospitals, and retail — rely on the BOSS-1's apron swap capability to run one machine across every job without bringing separate equipment for each floor finish specification. Facility maintenance departments in municipal buildings and universities with mixed floor types (VCT corridors, terrazzo lobbies, sealed concrete utility areas) use it to consolidate equipment inventory without sacrificing pad size flexibility. The 5-year motor, gearbox, and chassis warranty matters most to in-house maintenance teams amortizing equipment cost over multi-year service schedules rather than leasing on annual contracts.

BOSS-1 RPM, Pad Pressure, and Compatible Pads

The BOSS-1 runs at 175 RPM — the standard low-speed range for spray buffing, scrubbing, and stripping on VCT, terrazzo, resilient flooring, and sealed concrete. At this speed and weight (90–107 lbs depending on apron), pad pressure is approximately 40–55 lbs depending on apron size selected. Compatible with standard round floor pads in each apron diameter: use black or brown pads for stripping, green for scrubbing, red for spray buffing, and white or tan for polishing. Pads are sold separately. For burnishing applications requiring 1,000+ RPM, the BOSS-1 is not the appropriate machine — see Mercury's high-speed burnisher line. Optional Unicorn Weight Kit (5 × 10 lb weights, model UWK) adds downward pad pressure for heavy-strip applications. Optional 4-gallon polyethylene solution tank (model SST-4) with chemical-resistant hose enables wet scrubbing without a separate dispenser.
