Easy to attach, rolls smoothly over asphalt, dislodges most but not all mud and dirt with 2500 PSI pressure washer. After using this over the entire surface, the dirt may be loosened, but it is still on the surface. You need to redo with a regular pressure washer nozzle to push all dirty water, loosened sand, and dirt off the surface - but I expected that. The design of this unit means that it needs to be used carefully, as the wand extensions are not suitable for pushing this attachment side to side with anything other than a very small force. They are fine for pushing straight away from you, then pulling back towards you. We'll see how the surface looks in two days after it has dried completely.
I’m very happy with this pressure washer surface cleaner. It's great quality, works exactly as expected, and does an excellent job cleaning driveways, sidewalks, and patios. It was very easy to set up and use right out of the box. The cleaner moves smoothly and provides consistent, even cleaning without leaving streaks. It has definitely made pressure washing faster and easier. Highly recommend!
This unit works like a champ! I have used it to clean my pavers and am using it to clean my concrete driveway. It does an awesome job! It is so much easier to use than just the hand wand alone, and debris and water isn't splattering all over the place when you use it. I'm very happy with my purchase.
