Used it to pressure wash my 700 sqft pavers patio, that probably was never washed by the previous owner. There was build-up of moss, algae, etc. that it was looking dark grey. I was able to get rid of it mostly using the 25 and 15 deg nozzles. The machine had enough power to get it cleaned where now I can see the actual beige color pavers, shining. Really happy with the purchase. It took me about 5 hours, and the machine was able to handle the load. Would easily recommend. Also, it is very light to handle/lift, but at the same time the 4 wheels that fan out make it very stable, never feared it tilting. The only cons I can find (1) the soap dispenser is very small so have to refill it often. (2) the location of the soap dispenser opening makes it hard to pour the soap/cleaner in it. Have to remove the pressure hose hanging attachment, which is an east step, but an extra step, nevertheless. Since I was doing in small sections at a time, didnt bother me as much.
Everything just works! I love that is is booth portable (doesn't take up much room in the garage) but is stable enough with the 4 wheel base for me to pull it around on my paver driveway and I have yet to tip it over. This is really great when you have a long hose and it's not always by your side. I also think the design is well thought out with the way the nozzles attach to the base, which makes swapping tips a breeze. Much better than a previous electric power washer I owned. Highly recommended!
