The Mercury L-21E Lo-Boy Super Heavy-Duty floor machine has a 1.5 horsepower electric motor that provides a brush speed of 175 RPM for stripping, scrubbing, and polishing floors. This machine has a metal bell housing apron that measures 21 inches in diameter for wide floor coverage, with a nonmarking bumper to protect walls and baseboards. The 48-inch handle is adjustable for users of different heights, and can be locked into position during use or transport. The two triggers on the handle are nonconductive to reduce the potential for shocks. A safety interlock switch prevents accidental startups. This machine has a "B"/ "92" style brush drive plug for mounting rotary brushes and pad drivers (sold separately). A 50-foot, 14/3-gauge power cord enables the machine to cover a larger area without changing outlets than those with shorter cords. The unit has two 6-inch, nonmarking wheels for transport. The gearbox is located under the apron to reduce the operating sound level.

Floor machines use an electric motor to rotate a brush or pad against a floor to strip wax, scrub dirt, apply finish, polish, or buff a floor surface. Brushes and pad holders (also called pad drivers) are mounted to a clutch plate on the bottom of the machine, with different kinds of brushes and pads for different applications. When used with appropriate brushes or pads, floor machines can be used for cleaning wood, vinyl, tile, and other hard floors and for dry-cleaning and loosening dirt from carpeted floors. Some floor machines use an oscillating motion in addition to rotation, to enable brushes to reach more angles of rough floors or grout lines, and to reduce swirl patterns in floor finish. Floor machines for residential and commercial use have a handle for manual control and wheels for transport between work sites.
Mercury Floor Machines manufactures floor and carpet care equipment such as floor machines, burnishers, and vacuums. The company, founded in 1959, is headquartered in Englewood, NJ.
