I could have bought a larger truck mount if i wanted but i didn't see the point for the work i do. I carry 150ft of hose and have found that enough, i have done houses with loft conversions, town houses etc. and 3 storey flats. Other tm owners will say how resourceful you get running hoses! On domestics the prowler will do all that you need without a problem. All the commercial work i do is bonneting. I don't clean upholstery. If i had a large contract that required a 2 or 3 man HWE i would bring in other TM owners.
What attracted me to the prowler was the knowledge of John at restormate when i was phoning round looking at options and their reputation. A great plus point is the simplicity of the machine, Honda engine, easy to get at and service. Coupling that can be changed easy. Hoses that can be changed easy. I have not had any down time with the prowler.Costs pennies to run in relation to money earned, good machine for me. Obviously if you have contracts like Simon then you need more power but for me and my type of work it is plenty powerful enough.
Its very simple to flush solution hoses, Restormate supply a bypass wand with machine, open to flush, that's it.
