I have used a less expensive brand surface cleaner put because it was made of plastic it was hard to keep down on the ground. This unit has a good weight that makes it easier to control with less fatigue. I’am using a 3000 PSI unit. The attached wheels allow easy control and if you get to close to the edge of a step the stiff brush will not allow the nozzles to bottom out and damage them. I do wish that the quick disconnect pipe was a bit larger diameter it just feels a little light duty for the weight of the cleaner. All that said have not had any problems.
