Powr-Flite NM171HD Millennium Floor Machine – 175 RPM, 17", 1.5 HP
Powr-Flite NM171HD 17" Millennium Floor Machine: 175 RPM, 1.5 HP, Triple Planetary Drive
The NM171HD is Powr-Flite's 17" single-speed Millennium Edition floor machine — 175 RPM, 1.5 HP, all-steel triple planetary gearbox, rotationally molded polyethylene housing, and 109 lbs assembled in Texas. The 17" pad size fits tight corridors, restrooms, and building sections where a 20" machine cannot maneuver.

Tight-Space Scrubbing and Floor Restoration in Commercial Buildings
The NM171HD's 17" footprint navigates corridors, restrooms, and small office areas where a 20" machine sits too wide to turn comfortably. Despite the smaller pad, the 1.5 HP motor delivers the same torque as the NM201HD — the larger-pad 20" version — meaning the NM171HD handles the same range of tasks: stripping, scrubbing, sanding, grinding, shampooing, encapsulation, and bonnet cleaning. The triple planetary gearbox provides the sustained high-torque output required for stripping without the gear wear that direct-drive transmissions accumulate under continuous load. Rotationally molded polyethylene housing minimizes vibration transmission to the handle, reducing hand-arm fatigue during extended low-speed stripping runs.
NM171HD vs. NM201HD — 17" vs. 20" Millennium Single-Speed Machine
The NM171HD and NM201HD share the same motor (X8980-TI at 1.5 HP), transmission (triple planetary), housing material, and 175 RPM single speed. The NM171HD's 17" pad is 1 lb lighter (109 vs. 110 lbs) and fits tighter spaces. The NM201HD's 20" pad covers 38% more floor area per pass, making it more productive on open floors. The right choice is the 17" for buildings with narrow corridors and restroom access constraints, and the 20" for open commercial floors where productivity per pass matters most.
