The Clarke FM40 is one of the best machines when it comes to rectangular floor buffers. The FM40 allows you to get cleaner floors with fewer passes thanks to a heavy duty 1.5 horsepower motor, 160 pounds of down pressure and a 3,540 RPM pad driver. The floor buffer comes with 63 pounds worth of weights (3 weights at 21 lbs). Add this to the 98 lb machine, and you get a full 161 pounds of down pressure to maximize scrubbing and stripping.

This Clarke machine comes standard with a 14 inch x 20 inch pad deck and can use 14 x 20 inch scrubbing, polishing, and stripping pads, the FM40 floor machine can even be used to clean grout in bathrooms, prep gym floors for recoats, bonnet clean carpet, and burnish terrazzo, marble, and concrete.

Deluxe Version

Baseboard cleaning

The FM40 LX comes standard with an innovative baseboard cleaner attachment and easily attaches to the front of the machine to provide a convenient alternative for cleaning baseboards.


Switchable Modes

Easily switch between operating modes with the wheels up or on the floor. When the wheels are up, the FM40 LX provides the high fully directional maneuverability of traditional floor machines. When the wheels are down, it delivers high productivity forward-and-backward motion like a burnisher—with control so balanced that it enables single-handed operation and no fatigue.


Full Modularity for Easy Transport

The FM40 LX easily disassembles without tools to maximize the convenience of transportation. Each of its modular attachment components is painted bright yellow for easy identification. This allows BSCs and other operators who frequently lift and transport their equipment between job sites to separate it into easily manageable pieces.



  • Seamless chrome-plated handle tube resists rust and increased durability.
  • Operates in any direction very easily because there is no side torque.
  • Low noise levels allow for cleaning in the most noise-sensitive areas.
  • Totally enclosed, fan-cooled, motor for protection against overheating.
  • Heavy cast iron main frame supplies weight for aggressive cleaning.
  • Comes with a 3 year warranty on parts, 2 years on labor & 180 days for travel.
