That doesnt exist lol. If you can get access to a water valve somewhere in the complex then i suppose you could buy a hose and then do your thing. However, Imo your best bet is buy a bucket, microfiber wash mit and some microfiber towels. Then go to a car wash stall and bring the bucket ect, use the power washer to fill bucket and wash it by hand and then rinse it off. Dont forget to bring lots of quarters too. Hope that helps good luck.
