Y'know, now that I think if it, the last one I rented hooked to a kitchen sink faucet (unscrew the aerator and screw hose on). Maybe they all do that and I am wrong about a hose bib?
That kitchen one came with a hose long enough to go out the window and to the machine on the driveway.
Might have been $30 to rent for the day?
The water does not go very deeo. Seats were dry the next morning, after a 90 degree low humidity day. I think I put a fan in the van overnight.
If your butt is wet you will be cool but you might get a rash :(.
When I was a kid we used a foam carpet cleaning goo that came in a spray can. You wipe it in with a wet rag, let dry, then dry-vacuum. But I could not for the life of me find stuff like that when I looked a few years ago. Must have turned out to be toxic ;). Anyway, I think the machine works better.
3/4 timing in a DIY van conversion. Backroads, mountains, boondocking, sometimes big cities for a change of pace.
