Wanted: Wet Carpet Cleaner with no brush bar

Lady-Purr

Can anybody recommend a "non-rotating brush bar" wet carpet cleaner! Bit of a mouth full but we have a very expensive cream wool carpet that we are not to use a rotating brush bar on, the pile in the carpet is looped and the rotating bar makes the carpet fuzzy.
I have spend ages on the internet trying to locate such a cleaner but everyone seems to have this rotating bar! I have tried professional cleaners but would now like to purchase a good carpet cleaner to have at my disposal.

Any suggestions greatfully appreciated!!
