My son in law has one of those exact models, I used it to clean our driveway removing the clear polyurethane sealant but leaving behind the stencilling. Worked very well indeed, fast and very good pressure, select the right nozzle for the application and away you go. Gets about 5 hours to a tank full of fuel.
DO NOT use it whilst wearing thongs, its strong enough to slice the skin off your feet before you feel it. i shaved the side off my little toe and that pass removed part of the thong too. Did not feel a thing until i saw the red on the driveway, but that could be the intelligence of the user.
Son in law also has a 5000 psi job......wouldn't have a clue what he would use that for??? It would expose 30 year old concrete to a pebble finish for sure.
