Curious about your amendments to the Ninja. can you expand a little............like you, I've always tried to improve on any tools I've ever used and got some interesting results.
Daves idea of a " cleen off " is to get a carpet thats been dragged around a bus station or similar and have various systems compete..............but not sure if they all have to use the same products, etc
I read a report some time ago, where a particular product, used with a rotary, got a better result than a t/m, so there really is no black and white.
Great to see real life debate, excluding one contributor. No apologies Damian and I don't drink, but can't resist adding to peoples knowledge when I perceive a gap !
