Frequently Asked Questions
CRB (Contra-Rotating Brush) machines primarily use specialized low-moisture encapsulation cleaning solutions that contain polymers designed to crystallize around dirt particles as they dry, preventing resoiling and allowing easy removal by post-vacuuming.
While some standard detergents can be used, it is highly recommended to use solutions specifically formulated for CRB and very low moisture (VLM) cleaning methods, as traditional carpet shampoos often leave a sticky residue that attracts more dirt and can lead to wicking or overwetting issues not typically associated with encapsulation solutions.
Benefits include faster drying times (often under an hour), significantly less water usage, prevention of sticky residues and wicking issues, extended carpet lifespan, and the ability to keep carpets cleaner for longer, which reduces downtime in commercial settings.
Many modern encapsulation solutions are designed to be environmentally friendly, with features like low VOC content, pH-neutral formulas, and biodegradable ingredients; some specific products are even certified by organizations like the Carpet and Rug Institute (CRI) or meet DfE (Design for the Environment) standards.
Spotting solutions are typically more concentrated formulas used for pre-treating specific heavy stains with a trigger sprayer and manual agitation, and while they use similar chemistry, the main encapsulation solution is a diluted, ready-to-use product designed for application across the entire carpet via the CRB machine's sprayer or a separate pump sprayer.
Yes, many CRB machines are versatile and can be used to clean various hard surfaces like wood, tile and grout, and profiled floors, provided the correct brushes and a suitable, often pH-neutral, hard floor cleaning solution is used according to manufacturer instructions.
