Mercury BMT-175-Y BOSS Multi-Tasker – Single-Speed Floor Machine with Weight Kit and Solution Tank
The BMT-175-Y is Mercury's fully loaded single-speed floor machine. It runs at 175 RPM — the same scrubbing speed used on the BOSS-2 — but ships with the Unicorn Weight Kit (five 10-lb. weights) and a 4-gallon solution tank already included, eliminating the need to purchase accessories separately. The 1.5 HP A/C rectified motor drives three interchangeable apron sizes (13", 17", 21") via B/92-style clutch-plate pad drivers (12", 16", 20"), and the polished aluminum chassis adds structural mass that improves pad-to-floor contact.
BMT-175-Y Motor, Weight System, and Apron Configuration
Motor: 1.5 HP A/C rectified — runs cool and eliminates startup torque common in DC designs
Brush speed: 175 RPM — suited for scrubbing, stripping, and stone/marble restoration work
Unicorn Weight Kit: five 10-lb. weights (50 lbs. total) on a central mounting shaft — adds downward pad pressure for diamond and aggressive pads
Solution tank: 4-gallon polyethylene tank with chemical-resistant hose delivers solution directly through the apron to the floor
Apron sizes: 13", 17", and 21" with thumb-screw mount; pad drivers in 12", 16", and 20"
Power cord: 50-ft. 14/3-gauge safety cord — sufficient reach for large floor areas without moving the outlet
Warranty: 5 years on motor, gearbox, and chassis
Where the BMT-175-Y Gets Used
The combination of the weight kit and solution tank makes this machine particularly effective for stone, terrazzo, and marble restoration. Contractors running diamond crystallization programs or multi-step stone polishing programs use the weight kit to apply the 30–50 lbs. of additional downward force those processes require. The 4-gallon tank handles extended wet-scrubbing runs on VCT, epoxy, and sealed concrete without stopping to manually apply solution. The 21" apron covers roughly 3,000–4,000 sq. ft. per hour at a walking pace, which suits hotel lobbies, hospital corridors, and retail floors where size matters.
Pro Application Details for the BMT-175-Y
At 175 RPM, pad selection determines the result. Black stripping pads remove finish at this speed; green and blue pads scrub without stripping; red spray-buff pads restore gloss between full burnish cycles. With the Unicorn Weight Kit installed, aggressive diamond pads for stone honing seat correctly — without enough downward pressure, diamond pads skate rather than cut. The B/92-style universal clutch plate accepts most aftermarket pad drivers. The machine weighs 175 lbs. fully loaded with the weight kit, so it stays planted and tracks straight without operator effort.

Mercury BMT-175-Y BOSS Multi-Tasker Floor Machine – 175 R...
What apron sizes does the Mercury BMT-175-Y accept?
The BMT-175-Y accepts three interchangeable apron sizes: 13", 17", and 21", all mounted via thumb-screw. Corresponding pad driver sizes are 12", 16", and 20", with B/92-style universal clutch plates.
How much extra downward pressure does the Unicorn Weight Kit add?
The Unicorn Weight Kit includes five 10-lb. weights on a central mounting shaft, adding up to 50 lbs. of downward pad pressure. This is particularly useful for stone and marble restoration work that requires aggressive diamond or crystallization pads.
What is the RPM of the BMT-175-Y and what tasks is it suited for?
The BMT-175-Y runs at a single speed of 175 RPM, which is the standard scrubbing range. At this speed, black pads strip finish, green/blue pads scrub, and red pads spray-buff. For burnishing to a high gloss, you would need a separate high-speed burnisher (1,000+ RPM).
Is the 4-gallon solution tank included with the BMT-175-Y?
Yes. The 4-gallon polyethylene molded tank with a chemical-resistant hose is included in the box. It delivers solution directly through the apron to the floor during wet-scrubbing operations.
What warranty comes with the Mercury BMT-175-Y?
Mercury covers the BMT-175-Y with a 5-year warranty on the motor, gearbox, and chassis.
How heavy is the BMT-175-Y with the weight kit installed?
The BMT-175-Y weighs 175 lbs. when fully loaded with the Unicorn Weight Kit. This mass keeps the machine planted and tracking straight without significant operator effort.

Located in the Twin Cities in Minnesota, we acquired our Brio Air Filter in mid-late Spring of this year (2023) when pollen count was high and we were beginning to experience the effects of Poor Air Quality Index as a result of smoke particulates from fires in Canada that caused the air in much of Minnesota to become hazy and simply dirty.
It is so easy to share our experience with the Brio Air Filter given how quickly and efficiently it removed pollen, dust, and smoke particles from the environment inside our home. Two people in our home who suffer from pollen-related allergies during the spring immediately experienced easier breathing and elimination of symptoms within the house. With respect to smoke particulates from Canada drifting into our environment, EVERYONE in our home experienced directly improved breathing and smell of the air when entering from outside.
An additional piece of information to account for is that we have always employed high grade furnace filters in our home’s central HVAC system. With that high grade filtration in place both prior to and after acquiring a Brio home air filter, we all quickly agreed that deploying the Brio in our home made an easily noticeable positive difference in breathing inside our home. Additionally, those of us who clean our home have observed that dust builds up slower on our floors and furniture than before we deployed the Brio unit.
We did note that the Brio is not as quiet as a few other brands/models on the market that we have tried in our home but the efficiency and quality of the filtration, along with the air turnover rate it provides,allows us to locate the Brio unit in central rooms away from the bedrooms. Since we made that change there has been no noise-related effect on our sleep, while the unit maintains the same level of air cleanliness throughout our home.
A last key point to make is how easy the Brio unit is to maintain. The simplicity of the modular construction of the Brio unit makes it very quick and easy to keep the filtration sections clean. We have not yet reached a point of filter replacement but it is obvious to us that the replacement will take a matter of seconds and can be executed by anyone in our home, including our 10-year-old son.
It seems to help reduce my allergy issues. We're glad we bought it. The only problem I had was not seeing any cubic footage recommendations in the online description when purchasing the unit. Bedrooms vary widely in size!!
