The review does not address the tendency for all upright electric pressure washers to fall over and break the (usually) plastic hose fittings. The little footie in the front is not enough. The lay-out of the Karcher here looks like a big improvement. I have a very nice Karcher upright model after the front foot was added and the foot itself broke off right away. Then I had to stock hand-fulls of the fittings. Now I strap the washer to an actual hand truck just to keep it upright. My next pressure washer will have four wheels or metal hose fittings.
