Power washers are a handy thing to have, especially here in the south where mildew seems to grow on everything. I mostly use mine for washing the car and cleaning the concrete driveway and patio.
I have a Karcher electric pressure washer that works pretty good. You have to be somewhat careful pressure washing siding and brick, to prevent damage and leaks through the walls.
I have a small one like that. Use it to wash our sailboat since it gets yucky sitting in the harbor. Have hit my toe with it a few times and even it will cut skin. lol
I’m in the market to buy my second Karcher electric. First one has lasted over 12 years.
