I am going to try MR's pool of knowledge for something peculiar...

I'm looking for a portable (NOT HAND HELD) fully electric steam machine. It's for a very specific cleaning requirement (masonry actually). There can't be a boiler using any flame.

Must be capable of heating to up to 150celcius the water/steam, have adjustable pressure gauge, can be fitted with a variety of fan tip nozzles.

Something in the range of size of the larger Simoniz but for steam.

I need product suggestions. Fire away!
