Product Details
Overview
Austrian CRB Brush Sets are premium replacement brushes for professional Counter Rotating Brush (CRB) machines. Each set includes a matched pair of brushes designed to fit genuine Austrian TM3, TM4, TM5, Pro 35, and Pro 45 machines. With multiple stiffness levels to choose from, you can match the brush exactly to the carpet type, soil level, and job requirements for consistent, high-quality results.
The right brushes are critical to performance. Soft brushes protect delicate fibers and fine rugs, while standard and stiff brushes deliver the aggressive agitation needed for commercial carpet or restoration work. Our color-coded system makes selection simple, so your team can grab the right set quickly and clean with confidence.
Brush Types and Recommended Use
- White (Extra Soft) – For very delicate carpets and area rugs. Ideal for fine fibers, high-end Saxony, and sensitive textiles where gentle agitation is required.
- Grey (Soft) – For wool and soft residential carpet. Great for wool Berber, plush cut pile, and any situation where you want effective cleaning with a softer touch.
- Blue (Standard) – The everyday brush for most residential and light commercial carpet. Use on typical cut pile, cut loop, and level loop carpets with normal soil levels.
- Brown (Stiff) – For heavy soil and commercial-grade carpet. Ideal for restaurants, offices, and high-traffic facilities where you need stronger agitation. Requires proper break-in before use.
- Black (Extra Stiff – Hard Surfaces Only) – For tile, concrete, and hard surfaces with a Pro-series machine. Not for use on carpet, as it will damage fibers.

Best Practices and Important Notes
- Always match brush stiffness to carpet type. Using a brush that is too stiff can damage fibers or void carpet warranties.
- Stiff brown brushes should be broken in before use on carpet. Run them on a wet concrete surface for a few minutes to round off the tips.
- Black extra stiff brushes are for hard surfaces only. Do not use on any carpet, rugs, or soft flooring.
- Inspect brushes regularly for wear. When bristles become noticeably short, uneven, or performance drops, replace the set.
- Store brushes clean and dry between jobs to extend service life and prevent odor or contamination.
Frequently Asked Questions
How do I choose the right brush for the job?
Start by identifying the carpet type and soil level. Use White or Grey for delicate or wool carpets, Blue for most everyday residential and light commercial carpets, Brown for heavy soil or commercial-grade carpet, and Black strictly for hard-surface cleaning. When unsure, choose a softer brush and increase stiffness only if needed.
Will these brushes fit my CRB machine?
These brush sets are designed for genuine Austrian TM3, TM4, TM5, Pro 35, and Pro 45 machines. Select the correct size and stiffness for your model. If you’re unsure, check the model plate on your machine before ordering.
Can I use stiff brushes on residential carpet?
Stiff Brown brushes are intended for commercial-grade carpet and heavy soil conditions. For most residential carpets, Standard Blue or Soft Grey brushes are a safer choice. If you must use stiff brushes, always test in an inconspicuous area first.
How often should I replace my CRB brushes?
Brush life depends on usage, soil load, and the types of surfaces cleaned. Commercial accounts will wear brushes faster than residential jobs. Replace the brushes as a pair when the bristles become noticeably worn, uneven, or when cleaning performance decreases.
