We use our Edge Grimebusters these machines whilst being old are great as they require no power or water and carry up to 900 litres, although that only lasts 45 minutes but if connected with a hose you can have an operative work continually uninterrupted with hot pressure up to 160 degrees, and on red diesel this costs about £40 a day.
They are trailer mounted and can often be anywhere in the UK from day to day the difficulty is explaining to the general public the difference between our machine and one there friend has bought from B & Q which is cold feed only, once you have diesel machines often win hands down.
For us we would prefer 1/2 or full day work as opposed to continually doing small path ways but I guess that is what everyone in the market requires.
If you want to have a look at the machines feel free to view our website on
