The award-winning Hyrdoshot has changed the game. Cleaning the exterior of your home and your vehicles has never been easier, or more fun. But we wanted to kick it up a notch and see if we could make one that runs longer and is even stronger. So, our Worx engineers packed 725 psi into the Hydroshot ULTRA—and doubled its runtime. That’s more than twice the water pressure of the standard Hydroshot, and a full 275 psi stronger than the next most powerful model. And with two Power Share batteries supplying the juice, it lasts much longer than its 20V siblings before needing a recharge. Yet it’s still ultra-portable, at only 9.1 lbs, so almost anyone can spray down the siding on the house, then bring it around front to the driveway to blast the mud off the SUV. The brushless motor and new pressure hose with pump and cable combine for a hyper-efficient stream that draws just 1.1 gpm (gallons per minute) of water. The Hydroshot ULTRA boasts 797.5 total CU (Cleaning Units), as a matter of fact. What are those? That’s how the pressure washing industry rates the effectiveness of its products. And 797 is an awfully high score, especially when it’s coming from something that’s as portable and easy to carry as the Hydroshot. This version of the Hyrdoshot ULTRA comes with two 20V Power Share batteries and a 4-Amp dual charger. So, you’ll have the power you need to run this tool and every tool on the Power Share platform. Every Worx 20V Power Share battery is interchangeable with every other Power Share tool, saving you a bunch of money in the long run as you grow your tool collection.
