    Powerful power, washer, does a great job.

    [This review was collected as part of a promotion.] I put it together the day. I got it and tried it out, I was very impressed by the power of this pressure washer. The pressure washer cleans driveways very very well. I would recommend this machine to anyone who has to clean regularly such as driveways, siding, equipment. This power washer does a wonderful job.

    Excellent pressure washer!

    [This review was collected as part of a promotion.] This is a great pressure washer. I was tired of smaller, less powerful pressure washers with an unreliable engine. This pressure washer with a Honda engine starts on the first pull every time, and runs until it is out of gas.
