We had a Hoover Power Scrub Deluxe Carpet Washer, FH50150
carpet cleaner and ended up going through two in a year. It did the job well enough but was kinda meh. We saw on plenty of websites that it was highly rated so my wife and I figured it was as good as it gets. Well, after the second one (just returned it tonight) we got the Hoover Power Path Pro Advanced. The difference was immediate. The Power Path Pro is quieter than the Power Scrub. They both have separate soap/water compartments but I like this one's better. The Power Scrub always seemed to get some soap in the water container and then it bubbled like mad and the rinse part ended up getting the carpet soapy too. This one seemed to do a better job at keeping the two separate.
Carpet cleaning was much better with the Power Path Pro. The brushes move way faster and seem to keep the carpet fibers separate to suck out more water. The carpet was barely damp after sucking it up.
The dirty water container is much better designed too. The Power Scrub had several spots that never got clean. Dirt and grime built up and looked gross and smelled. Time will tell with the Power Path Pro but so far, the dirty water bin cleaned up much nicer. If it stays like that, it'll be a huge bonus for me.
Negatives about the Power Path Pro. Its much harder to clean up after using. Yes, the dual V suction part comes off and cleans up easily, but the roller brush compartment is very dirty. It kicks up pet hair, dirt and whatever else is on the carpet. It sticks to the clear acrylic and that part doesn't come off without dissembling the entire thing. I ended up having to use cups of hot water and pour it over the roller brush to clean that area out, turn the brush by hand to pick off any pet hair and do it more. All in all, it did come clean but it was a mess and a pain. I'll probably use my kitchen sink next time with our faucet hose. That however was the worst part and IMO, its not a deal breaker for me. Considering that I vacuumed yesterday, it may be a deal breaker for me to ever thing about buying another Dyson.
