Yes , Giant rug doctors .
There is nothing intrinsically wrong with the RD design , its just as a whole a bit Micky mouse for Pro CC .
The Prochems are aimed at maintenance cleaning more so and the design can limit the results you can achieve , they dont need lots of vac power because there is no hose run to deplete airflow or vacuum and the powerbrush design does not need lots of psi to be effective .
The steamin demon is rated by Pro CC although it also has just one low power vac close to the cleaning head . It relies on high flow from a tap instead of a powerbrush . Its suppose to be a Pain to setup and use though in general .
