Alan,
As a t/m owner who does 3 to 5 mainly domestic jobs daily (and who also has a Ninja) I do not consider myself a bit short up there. I used my ninja to pay for my truck mount, but I would now rather watch day time tv than use it.
A t/m is not the be all and end all, but for me it its the best solution. If I worked in london or other city then it would probably be a pain, but I dont.
Its quicker on most jobs, hotter and leaves carpets drier. I dont have to constantly fill and empty, and its more reliable. I also dont consider myself superior to other cc's whatever equipment they use.
PS I used to use upto 75 foot of hose on my Ninja, and did curtains with it aswell, the van knew its way to Dartford VERY well, I have had a couple of problems with my t/m none of which stopped it from cleaning, all were sorted over the phone promptly. I suggest you engage brain, before operating mouth in future.
