Very simple to put together. Used it for a few hours right away, on our Lannon Stone wall, and very impressed with the power. Easy to use, lightweight, and powerful!
I had a gas washer that worked really well, but the intake valve broke and rattled around enough to destroy the piston and cylinder. I was hesitant about buying an electric washer, but borrowed a smaller unit from my neighbor, and it worked out well. Purchased this washer and has done well so far with no issues. My only complaint is with the cord wrap holder. It should have legs extended on the bottom so that the cord doesn't want to slip off when your wrapping it up.
