New NSS MUSTANG 300DS 20" Floor Machine
Our Take (from the SES Sales Team)
“For open hallways, cafeterias, gyms and retail sales floors, the Mustang 300DS 20 in puts more pad on the floor with every pass. NSS rates the 20 in at 3,600 sq ft per hour scrubbing and 10,000 sq ft per hour polishing, compared with 2,700 and 7,000 for the 17 in. The dual speed motor is what makes it so useful. Run it at 180 rpm to scrub or strip, then flip the switch to 300 rpm to spray buff, polish or bonnet clean carpet. That is most routine floor care from one machine. The 1.5 hp motor drives the pad through a 3-idler planetary gearbox, the steel skirt is powder coated, and a safety-yellow vinyl bumper protects baseboards and fixtures. A mechanical lock-out switch keeps it from starting by accident, and the handle height adjusts for each operator. It plugs into standard 115 V power with a 50 ft cord, and it comes with a pad driver. If most of your rooms are small or full of furniture, the 17 in Mustang 300DS may be the easier machine to handle.”
A 20 in dual speed floor machine
The NSS Mustang 300DS 20 in is a heavy-duty rotary floor machine that scrubs, strips, spray buffs, polishes and shampoos. A switch on the motor changes the pad speed from 180 rpm to 300 rpm, so one machine handles low-speed scrubbing and high-speed polishing.
This unit has the 1.5 hp, 115 V motor, a 50 ft cord and a pad driver, ready for your pads.
Condition: New.

Choosing a size
Mustang 300DS 20 in vs. 17 in
| Task | 20 in (this unit) | 17 in |
|---|---|---|
| Polish | 10,000 sq ft/hr (929 m²/hr) | 7,000 sq ft/hr (650 m²/hr) |
| Scrub | 3,600 sq ft/hr (334 m²/hr) | 2,700 sq ft/hr (251 m²/hr) |
| Spray buff | 3,100 sq ft/hr (288 m²/hr) | 2,700 sq ft/hr (251 m²/hr) |
| Shampoo | 1,430 sq ft/hr (133 m²/hr) | 1,200 sq ft/hr (111 m²/hr) |
The 20 in covers more floor per hour in open areas. The 17 in machine is easier to handle in smaller rooms, restrooms and around furniture.
