What Is an Auto Scrubber Brush?
An auto scrubber (automatic floor scrubber) uses brushes or pads to scrub the floor while a squeegee recovers the water. The brush is the main wear item — it scrubs the dirt loose and must be replaced regularly to keep cleaning performance high. Auto scrubber brushes come in disc, roller, and cylindrical styles depending on the machine.
Disc Brush vs Roller Brush for Auto Scrubbers
Auto scrubbers use one of two brush systems:
| Type | Machine Example | Best For | Replacement Cost (Factory-Direct) |
|---|---|---|---|
| Disc brush | Most walk-behind auto scrubbers | Smooth floors, sealed concrete, tile | 45-75 USD |
| Roller brush | Tennant T7, Hako B90 style machines | Rough concrete, debris, one-pass cleaning | 55-95 USD |
Brand Compatibility
Most auto scrubber brushes use the NP-9200 2-lug standard, which fits Tennant, Nilfisk, Viper, Comac, Karcher (with adapter), and most Chinese OEM machines. Some machines need 3-lug or 4-lug mounts. Before ordering, send us your machine brand, model, and a photo of the current brush — we confirm compatibility within 24 hours.
Signs Your Brush Needs Replacing
Replace the brush when you notice:
- Streaks or a film left after cleaning.
- Bristles flattened or shorter than 12 mm.
- The machine vibrates more than usual.
- Cleaning time has increased for the same result.
- You can see the backing plate through the bristles.
