Many Many thanks gentlemen for your replies here.
There is some good advice and although I have cleaned carpets for the last 20 years on and off, I have never used a T/M. On the point of mobile units, yup got some Prochem ones which will still be carried.
They are clearly a large investment especially when looking at multiple units so understanding the choices is very important and really only possible by talking to guys like yourselves in the field.
There are a lot of highlighted points here including type of vehicle, volume of work, ease of servicing and cost of parts which are all valid issues.
The concept is to make additional use of the kit in other trades (mainly out of fear) with one being particularly specialised which adds to the problem slightly in respect of pressure and carryable water but maybe solvable with an additional pump and small towed bowser.
So have contacted Prochem today (only 30 mins away) by way of making a start (and spoke about the everest which sounds like a bit of a beast along with the price)
Um embarrassingly "Preston" what’s there and when?
If its not too far away then Ill wait, otherwise ill have to get out there and see these other manufacturers wherever they are.
Once again guys Many Thanks.
