I bought this elective washer since I will only use it close to the house and didn't want to mess with gas. It has worked great for cleaning the patio after the winter muck and cast washing. In a couple more years I am sure it will work well for siding cleaning as well.
I had a gas-powered pressure washer for years before buying this electric washer. I love this machine - no gas motor maintenance - plug in and go. I like that the motor stops automatically when not spraying. It easily takes care of all of my pressure-washing jobs.
