I actually have that exact “power” washer. It just hooks up to a garden hose, not very powerful. I used it to rinse off the siding before I painted the house. It was on sale for $5 at Rite Aid, of all places.
Yeah, the “power” in that washer is just water pressure squeezed down into a very small tube. The only way water is going to get inside that house is if they left the windows open.
I suppose it might give someone the idea to try that with a real power washer, but that’s nothing to do with this product.

This final week is for Shark Week 2013, on Animal Planet. Possibly the funniest commerical I ever saw.
