My wife bought one of those on line power washers. It worked great for cleaning about 1/2 of the siding on our house, then the water started coming out of the handle. I got the job done, but towards the end, there was more water running down my arm then was coming out of the pressure end.

The next one my wife bought was a cheap one from HF, it did the house, and still works, and was cheaper then the online washer was.

The online washer had a much nicer soap dispenser and also had a longer wand which made cleaning the higher places much easier, too bad it died so soon.

If there is a HF store near you, I'd buy one from there before I'd buy one on line, at least when the HF one dies, you have someplace to take it to and get another one "just like it". Gene
