You obviously very pleased with your Powerflite, I was too when I had a CFR500 3-4 years back.
but we must be careful to watch what we say.
for example
4 buckets in, 4 buckets out - that would mean the carpets would be 100% dry as your wand passed over them, and obviously they not. The recovery system is good and the recycling system does mean less bucketing, but even so, I had to top up, and even change, the dirty water that was being recycled.
also the water heating system is good, but to say no loss of heat....mmmm! Put your hand near the exhaust port - is it cold? If not then that means heat is wasted.
Yes I used to have a CFR500, now I have a Scorpion, a 3 vac machine that new doesnt cost much more then what you paid for your 2 vac, and the inline heater is separate so you can get the heat nearer to the wand when you are working on long hose lengths.
