The Mercury L-20E is a 20-inch single-speed Lo-Boy floor machine built for facility cleaning crews and contractors who need a workhorse buffer that can scrub, strip, spray-buff, shampoo, and bonnet clean without the noise and vibration of cheaper rebrands. Powered by a 1.5 HP A/C motor turning at 175 RPM through Mercury's triple-planetary high-torque transmission, the L-20E delivers steady torque under load while staying quiet enough for daytime cleaning in occupied buildings.
Built for
- Building service contractors covering schools, offices, healthcare, and retail
- In-house facility teams stripping and refinishing VCT and resilient floors
- Hospitality and hotel housekeeping running daily spray-buff routes
- Apartment turn crews bonneting carpet between tenants
Why the Lo-Boy design matters
Floor cleaners on commercial cleaning forums consistently pick the low-profile Lo-Boy chassis when they have to scrub under desks, beds, and conference tables without lifting the wires. The reduced motor housing height clears under most furniture, and the all-metal frame absorbs vibration so the operator's hands and arms stay comfortable on long runs. Once the pad starts spinning, the triple-planetary transmission keeps the brush turning at full RPM under heavy strip-pad load.

Frequently asked questions
What pad does the L-20E take?
A 20-inch floor pad on a compatible 20-inch pad driver. If you are using a pad driver with a riser block, confirm clearance with Mercury before ordering. We can match a pad driver and starter pad set when you order.
Can it strip wax?
Yes. At 175 RPM with a 1.5 HP motor, the L-20E is rated for chemical stripping with a black or brown strip pad. For best results pre-soak with stripping solution, work the floor in 4-foot by 4-foot sections, and pick up the slurry promptly with a wet vac.
Is this single speed or variable?
Single speed. 175 RPM is the workhorse speed for scrubbing, stripping, spray-buff, and bonnet cleaning. For high-speed burnishing you need a separate burnisher rated 1500-2500 RPM.
How loud is it?
Mercury markets the Lo-Boy as ultra-quiet for the 1.5 HP class. Real-world operators report it is noticeably quieter than equivalent imports, which is why many use it during daytime cleaning in offices and healthcare without disturbing occupants.
Does it come with a pad driver?
This SKU is the machine itself. Pad drivers and pads are typically purchased separately or as a starter package. Confirm at checkout if you want a complete bundle.
Discount Cleaning Products is an authorized Mercury Floor Machines dealer. US-based customer service can help match the L-20E to a pad driver, brush, and pad set, or step you up to the L-21E if you need a wider apron.
