Hi Paul,
That was probably my post you read. I have been using the Rx 20 along with my powerfilte for about 2 years now and find it absolutely brilliant along with the powerflite. I have never had a problem recovering water and as a matter of fact, have practically retired my wonderwand as a result of its performance. Admittedly there is quite a bit of emptying and refillling but i feel its worth it because of the end results. Along with that I know its a heck of a lot faster than using traditional wand even with the emptying and refilling. I must admit the model I have is the HE model and it has 3 Jets and 5 vac slots.
Best investment ever IMO.
Buy one you'll never look back.
Regards Bren.
