I've had my powrflite 500 for just over 2 weeks now.
My first thought when it arrived was, what the f**k have i done.
It's big and heavy but does load easily thanks to the dolly wheels on the handles.
with tap hot water in the 55 litre tank, and the perfect heat valve open, it pumps it out very hot. Suction is on a par with my Ninja, cleaning carpets at 4 - 500 Psi, gets through the solution quickly, but the wonder wand leaves 80/20 virtually dry.
I think perhaps seperate lines instead of the hide a hose would increase CFM even more.
The drain hose is a bit of a dogs dinner, but a waste gate would stop the easy loading.
There is a Knack to filling it as the solution tank opening is very small. The pigtail leads take some getting used to. but i have used a Ninja for 6 years so anything is going to be different. The body is not as well made as a Ninja, but overall in performance it's very impressive. A cotton suite i did the other day was dry before i'd finished 3 carpets, and i do not blow dry suites and never have, my customers are happy with 12 hours drying times, for the prices i charge.
Customers are impressed with it and know you mean business. It makes the NInja look like a toy. With 60 feet of hose i can honestly see no difference at all to 30 feet, time will tell if it's reliable.
I don't know what pump is on it, as although 500 PSI, the other day i inadvertantly wound it up to 700 PSI.
I've experimented with pressures, and today cleaned some factory offices low profile carpet, out in the sticks so very dirty, 200 PSI did a fabulous job, and used water at about same rate as 100 Psi Ninja, just wound it up to 400 Psi to finish the worst areas near the door in from the farm yard.
