20-Inch vs 22-Inch Scrubber Specs
Cleaning Width
The Powr-Flite NM2000 features a 20-inch cleaning width, while the Purilitzs T381 offers a 22-inch cleaning width. The two-inch difference in the Purilitzs model allows for slightly wider coverage per pass. This can reduce the total number of passes needed to clean a large commercial area. The Powr-Flite is designed for standard polish coverage. The Purilitzs combines scrubbing and drying in one pass. You should measure your aisles to ensure the 22-inch width fits comfortably. Both machines are built for commercial hard-surface cleaning. The wider path on the Purilitzs may speed up routine maintenance in open warehouses or retail spaces.
Brush Speed
Brush speed is a critical spec for floor maintenance. The Powr-Flite NM2000 operates at 2,000 RPM. This high speed is typical for burnishers that polish and shine floor finishes. The Purilitzs T381 runs at a much slower 200 RPM. This speed is optimized for scrubbing and extracting water rather than polishing. High RPM burnishers are best for restoring gloss on epoxy or marble. Lower RPM scrubbers are better for removing dirt and grime. You need to choose based on your primary goal. If you need a high-gloss finish, the Powr-Flite is the clear choice. If you need deep cleaning, the Purilitzs is more appropriate.
Power Source
Power sources differ significantly between these two machines. The Powr-Flite NM2000 is a corded electric unit. It requires a power outlet and a power cord for operation. This limits your range to the length of the cord but provides continuous power. The Purilitzs T381 is a battery-powered walk-behind scrubber. It offers three to five hours of runtime on a single charge. It takes eight hours to fully charge. Cordless operation eliminates tripping hazards and allows you to move freely without dragging a cord. This makes the Purilitzs more convenient for large, open areas like warehouses or long corridors.
Tank Capacity
The Purilitzs T381 includes substantial tank capacities. It has a 15.9-gallon solution tank and an 18.5-gallon recovery tank. These large volumes allow for extended cleaning sessions without frequent refilling or emptying. The Powr-Flite NM2000 is a burnisher. It does not use water or cleaning solutions. Therefore, it has no tank capacity. It is designed for dry polishing or applying finish. You do not need to manage water tanks with the Powr-Flite. However, if you need to wash floors, you must use the Purilitzs. The tank sizes on the Purilitzs support continuous wet cleaning in large commercial facilities.
Motor Power
Motor specifications highlight the different functions of each machine. The Purilitzs T381 uses dual 550W brushless motors. One motor drives the brush at 200 RPM, and the other powers the suction system. Brushless motors offer stable suction, lower noise, and extended durability with less maintenance. The Powr-Flite NM2000 does not list specific wattage in the provided data. It is described as an electric burnisher with a power cord. The focus is on the 2,000 RPM output rather than wattage. The dual motor system on the Purilitzs ensures both scrubbing and water recovery work simultaneously and efficiently.
Choose based on your floor type
You need to polish existing floor finishes
The Powr-Flite NM2000 is an electric burnisher designed to polish hard surfaces. Its 2,000 RPM brush speed provides high-speed friction to bring out a shine on sealed floors. The 20-inch cleaning width covers standard areas efficiently. This machine is built for maintaining the appearance of finished surfaces rather than deep cleaning or washing.
You want to wash and dry floors at once
The Purilitzs T381 is a walk-behind scrubber that washes and extracts water simultaneously. Its 22-inch brush width and 33-inch squeegee clean and dry floors in a single pass. The 550W brushless motor provides strong suction to recover dirty water. This machine is ideal for removing dirt and grime from concrete, tile, or epoxy surfaces quickly.
You prefer cordless operation for large spaces
The Purilitzs T381 runs on a battery, offering 3 to 5 hours of runtime. This eliminates the need to manage power cords in large warehouses or retail stores. The 18.5-gallon recovery tank and 15.9-gallon solution tank allow for extended cleaning sessions without frequent refilling or emptying. You can move freely across aisles without tripping over cables.

Can a 20-inch burnisher replace a standard floor scrubber?
