The Mueller Model O-92 is available with CRS (Circulation cleaning) or VRS cleaning system (rapid cleaning).
CRS cleaning system
The circulation cleaning system was developed in the early 1990’s. This fully-automated cleaning system (based on circulation cleaning) is mounted on the front side of the O-model.
VRS cleaning system
The cleaning system was further developed into a quick-wash cleaning system at the end of the 1990’s. This quick wash or displacement cleaning system has major advantages compared to the circulation cleaning system:
- More economical (about 35% water saving)
- Quicker (about 50% less cleaning time)
- Environmentally friendly (less water and electricity consumption)
