I have a powerful gas-operated pressure washer. It takes some time to get set up. THIS TAKES VERY LITTLE TIME TO SET UP — IT IS SO CONVENIENT!!!
I have used it on my vinyl fence, and my patio made of pavers. It worked well enough on both of them. On the vinyl, I desired more pressure since I had not cleaned it in some time. The patio had not been cleaned in some time either, but the pressure was adequate and kept me from damaging them (which my other washer could do).
I also used it with a special hose to clean out a clogged kitchen drain that had been getting clogged repeatedly. After scoping it with a borescope, I saw that it really needed to be cleaned due to some hardened blockages that had bonded to the sides of my PVC piping. I was able to quickly set up the power washer, connect it to the hose and I was quickly in business – this is such a convenient unit.

The unit quickly stores away and takes up very little space. It is lightweight and the handle compresses downward to take up even less space.
