Take a look at my new "toy"
Going to use this in the winter to get the underbody of my car good. I try and do it now at the do-it-yourself carwash, but I never have enough time to really get it good. I can now jack it up myself and give it a good cleanin' under there. 4 HP engine has plenty of power for anything I would want to do and it has 4 nozzles as well as a detergent pickup for soap and whatnot.
Of course this will not replace hand washing it in the summer, but it gives me a nice option in the winter when the temp. gets above freezing.
