I've used an
Rx20 and it is more pain than what its worth.
1. two hands to use
2. 2 hoses and one electrical cord to deal with
3. hard to tell the flow
4. can't use on all carpets
5. too many moving parts that might fail
6. a glided wand is easier to use...less fatigue
7. Too much space in van taken up
8. It's just an expensive tool to make it look easier to clean but really only makes things more difficult.
9. It's a money maker for the company that makes them...not for you.
With a light weight scrubber and a good prespray and an awesome glided wand with alot of flow and suction kicks ass in the nasty's.
