Did it clean when it did work?
Seems a little odd to rely on water to rotate it.

Excellent question, Brian.

I have a similar unit for a different washer. My complaint is that the
jets do an excellent job of cleaning a very narrow circular strip. Moved
across the patio at any speed you create a *coiled spring* pattern.

I think the OP has a pump problem. Frost damage has always been a risk
with pressure washers stored in garden sheds.
