How many capet cleaning machines are you going to buy and sell before you settle down?
Well done mate. I think it's the best system on the market. In fact if anything, now that you realise that vacuum power is not the essential ingredient the 750 psi single vac ozone is the one to go for.
By the way I have designed an ozone system for the Ninja! I'm not releasing the details just yet but suffice to say that the componentry involved FAR surpasses what the CFR version does. Not that the CFR doesn't work - It's brilliant. It's just that their system relies on the water continually recirculating to sufficiently Ozonate the water. Their system WILL NOT work in any other extraction machine because it CANNOT produce sufficient Ozone quickly enough.
I've done a lot of research on the subject and put together what I consider to be a bombproof 'One Box' design incorporating CFR's perfect heat coils 'inline' before the V2 heat exchanger OR the whole system can be 'shoehorned' into the Ninja while still retaining the twin vacuum system. It's more than the CFR version, but it works differently and has the hallmark of being more reliable. NO-one else out there makes it.
I'll post how I get on with it once I've got it up and running.
But yes, buy CFR. I believe it's the future of carpet cleaning, although I feel more so in the commercial market .
All the best - Is the 'fiver' in the post ?
