I cleaned my red cedar fence with ease. No chemicals just power washer. My gas powered washer would not start after sitting up last winter. ( go figure). I am pleased with this unit.
This washer has enough power for my needs. I was able to remove several years of built up mold and mildew from the north side of my house. Did a good job cleaning my patio with the addition of the SPX-PCS10 patio attachment. My only negative is winging up the hose for the gun, there should be a reel or some easier way to hang the hose when not in use. I would recommend this washer to a friend
