Hi
I might be missing something here but if you do have a steameasy and your client is on the top floor, say 5 flights of steps, how would you keep it outside . I take it from your post you mean out in the street?
Truckmounts maybe, although a lot of hose would be required, if you had a portable then you would still need to fill it up i.e. at the customers tap.
Or are you suggesting to lug it up say 5 flights, then back down with heaps of hose, clean the flat in question, lug it back up to empty it and then back down so you can go to the next job and maybe do it all again.
I would have to disagree here in that not ALL CC keep their machines outside. It is not practical or feasible.
Your thoughts
Regards
Martin
