Bestbuy offers WORX - Hydroshot 20V Electric Pressure Washer up to 415 PSI at 0.53 GPM (1 x 4.0Ah Battery and 1 x Charger) - Black for $79.99 (orig. $139.99) free shipping.

Product Description:
This is the base Hydroshot, but with a bigger battery, so you get twice the runtime than the standard model. The 20V Power Share 4.0Ah Hydroshot Portable Power Cleaner lets you wash more cars, bikes, or camping gear in one go. Its included 4.0Ah battery has 2x the capacity of the basic 2.0Ah version. What’s more, the included bottle connector means you can take this Hydroshot anywhere without the need for a freshwater source to dip into. Just screw on any common 2L plastic soda bottle and take this power washer on a road trip or to any place where having a large bucket filled with water might be an inconvenience. Or, just use the Hydroshot the tried-and-true way and drop the included 20-ft. hose into the lake, marina, or any freshwater source. And you can always hook it up to the faucet or the spigot outside. The Hydroshot is also perfectly calibrated to deliver the right amount of pressure for moderate cleaning tasks around the home or cabin. Too much pressure (like you get from a pressure washer), and you’ll strip the paint off the deck, not enough, and you won’t get the mud out of those tires. The Hyrdoshot isn’t a pressure washer, it’s made for quick routine cleaning of things like patio furniture, grills, window screens, beach gear, bicycles, stairs, SUVs and boats. It’s great for spot cleaning, delicate surfaces, boots, kayaks and canoes, outdoor equipment, garage floors, fencing, and sidewalks. And it’s a blast to use (get it, blast?), so you’ll clean more often when you’ve got the Worx 20V 4.0Ah Hydroshot.
