Purchased a wilks 550i pressure washer in December. Opened it up today. It's so easy to assemble and it has alot of attachments for different jobs from the car paths and guttering. My first impression of the power is its the same as a garage car wash. Fantastic power output did the car in no time. The car wheels had alot of dirt and grime and the machine made short work and brought them up like new. I then turned the gun to the drive way it blasted all the moss and dirt away instantly. It comes with an attachment for every job as well as one for the underneath of the car and it works for the guttering around the house. Great product highly recommended.
