The BRC 45/45 C offers two functions in one machine. As well as giving superb deep cleaning results in a single pass, the 45/45 can be used for interim two-stage cleaning - providing fast, efficient cleaning of carpets with very short drying times. Using Karcher's fast drying carpet cleaner RM 768 detergent, medium-larged area carpets can be cleaned and are ready for vacuuming within 20 minutes.
