Bestbuy offers WORX - Hydroshot 40V Electric Pressure Washer up to 585 PSI at 0.9 GPM (2 x 4.0 Ah Batteries and 1 x Charger) - Black for $139.99 (orig. $229.99) with free shipping.

Product Description:
The 450 PSI – 40V Hydroshot Portable Power Cleaner is the beefier version of the popular standard Hydroshot model. With 130 more PSI (Pounds per Square Inch) and twice the battery, you get a stronger, high-performance, power washing machine. If you get your SUV or RV really dirty, this is the tool for you. If storm season leaves loads of mud and grime on your decks and driveways, this is the power washing wand for you. If you’ve seen or have the standard Hydroshot and thought, “this is pretty cool, but I want it to be stronger,” this is the Hydroshot for you. Even with all those PSIs, it only pulls 0.90 GPM (Gallons Per Minute). And it only weighs 5.1 lbs, so it’s easy to hold up for long stretches. This model comes with: two 20V 2.0Ah Power Share batteries, 2-Amp Dual-Port Charger, Long Cleaning Lance with 4-in-1 Nozzle, 20-foot Draw Hose, and a Quick-Connect Adapter. There are stronger pressure washers out there, there are even Hydroshots that pack a more powerful punch, but this is the right-sized version for the right jobs. Traditional pressure washers have a separate power source attached that you have to lug around. Not this Hydroshot. Power cleaners that are more powerful than this one can damage a vehicle’s finish or strip the paint on the deck. For routine, moderate to tough cleaning of cars, trucks, boats, and around the house, you’ll want this 450 PSI – 40V Hyrdoshot Portable Power Cleaner.
