I really like this power washer over the gas one I had. Too much messy oil and gas and difficult to start. It has about the same amount of power as the gas one. I don't mind transporting the electric washer because I don't worry about leaking fluids.
I bought this after going through two Karcher plastic surface cleaners, kept falling apart, this is screwed together socket head cap screws, only concern my cleaner spray bar has alot of Teflon tape around connection,hope a leak doesn't start here.
If you even occasionally pressure wash your concrete driveway, patio, or sidewalk, you need this. It just works. Just attach it to the end of your wand with the quick-connect and go. It is so much faster and easier than using the wand. It doesn't remove everything with just one pass, so you do have to move back and forth and overlap a little as you go, but this is to be expected. When you do this, it cleans well. I used the wand to go back over an area that I first did with the surface cleaner, and I couldn't tell much difference. Because of the round shape, it obviously can't get into corners, and it leaves a small patch uncleaned right next to walls, so you will need the wand for those areas, but you won't care. This thing is a time-saver and a back saver. I wish I had bought it years ago. 5 stars.
Finally got to use this on patio. What would normally take well over an hour probably only took about 15 minutes. And no streaks were left. Definitely one of the best purchases I have made.
