20-Inch Floor Buffers for Large Commercial Facilities

What 20-Inch Floor Buffers Are Used For

The 20-inch single-disc floor buffer handles the same four tasks as smaller machines — spray buffing, scrubbing, stripping, and pad cleaning — but with a 17% larger cleaning path that translates to meaningfully faster production in open-floor commercial spaces. Gymnasiums, warehouse aisles, large dining areas, hospital corridors, and school hallways are standard applications where the additional 3 inches of path width reduces the number of passes required per square foot. Running at 175 RPM, 20-inch buffers are compatible with standard 20-inch pads and brushes available from all major floor care supply distributors.

20-Inch Buffers vs. Larger Walk-Behind Scrubbers

A 20-inch floor buffer requires manual solution application — a mop-and-solution step before the buffer passes — making it a two-step process for scrubbing compared to a walk-behind scrubber that dispenses solution automatically. In exchange, a buffer costs a fraction of a walk-behind scrubber, requires no solution or recovery tank maintenance, and handles multiple tasks (buffing, burnishing, stripping) that a dedicated scrubber cannot. Facilities with large budgets and high daily scrubbing requirements justify a walk-behind scrubber; facilities doing weekly or biweekly maintenance buffing and periodic stripping get better return from a 20-inch buffer machine.

Related collections: 17-inch floor buffers, 13-inch buffers, floor scrubbers, Namco Manufacturing, Mercury floor machines

Selecting a 20-Inch Buffer for Your Facility

Motor amperage determines stripping capability: larger motors maintain speed under load when stripping heavily coated floors or driving thick scrubbing brushes, while minimum-spec motors bog down and generate excess heat. For spray buffing and light scrubbing, any 20-inch machine handles the task. For stripping aged floor finish in high-traffic areas, select machines with 1.5-amp or higher motor ratings and ball-bearing construction to support the extended run times that stripping requires. Confirm pad-driver compatibility before purchase — most 20-inch machines use a standard 20-inch driver, but some budget models use non-standard attachment systems.
