Product Description:
This is the base Hydroshot, but with a bigger battery, so you get twicethe runtime than the standard model. The 20V Power Share 4.0Ah HydroshotPortable Power Cleaner lets you wash more cars, bikes, or camping gearin one go. Its included 4.0Ah battery has 2x the capacity of the basic2.0Ah version. What’s more, the included bottle connector means you cantake this Hydroshot anywhere without the need for a freshwater source todip into. Just screw on any common 2L plastic soda bottle and take thispower washer on a road trip or to any place where having a large bucketfilled with water might be an inconvenience. Or, just use the Hydroshotthe 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 thefaucet or the spigot outside. The Hydroshot is also perfectly calibratedto deliver the right amount of pressure for moderate cleaning tasksaround the home or cabin. Too much pressure (like you get from apressure 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 apressure washer, it’s made for quick routine cleaning of things likepatio 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, andsidewalks. And it’s a blast to use (get it, blast?), so you’ll cleanmore often when you’ve got the Worx 20V 4.0Ah Hydroshot.
