The brush is the workhorse — it's the part actually digging into the soil while the rest of the machine plays a supporting role. Everything else is expensive infrastructure so the brush can do its job. When bristles wear short, the machine's still doing all its work, but the brush isn't reaching the floor properly. That's a lot of watts turning into disappointment.
This is the genuine Nilfisk Advance OEM 4 inch Polypropylene Cylindrical Brush, part number 30231A, brand new in the box. Bristles have a working length — once they're worn down past it, the machine is dragging them, not scrubbing with them. Check bristle length once a month and you'll never be surprised.
polypropylene brush perfect for every day interim cleaning, such as concrete floors and tile floors with grout lines. One brush is included with your purchase, and all machines require two brushes to operate.
Genuine OEM means the correct bristle grade, correct block dimensions, and correct drive engagement. Aftermarket brushes that are "close" wobble on the drive and wear out early.
