Portable, Practical, Useful & Effective Now, that's a nice bunch of adjectives, but what can the Ivation Multi Purpose Washer really do for you? In a line, it turns four and a half gallons of water into a truly portable washing system that you can take literally anywhere. It is rated at pressure levels of up to 130.5 PSI. This means that you won't get an aggressive pressure-washer, but rather enjoy a nice, gentle stream that is actually manageable and exceptionally useful in real life. From washing your vehicle to showering on a hike to watering your garden to washing your pets - the list of possible uses and applications for this washer on wheels is quite endless. All-in-One Design Makes It One for All Let's add another few adjectives to the previous list, shall we? Clever. Self-sufficient. Versatile. You get the picture. The Ivation Multi Purpose Washer is designed to function as a standalone, lightweight, all-inclusive portable washing system. A built-in large-capacity rechargeable battery enables you to generate a water spray even were a power cord or water hose is not available. The Multi Purpose Washer also readily accepts juice from your vehicle's cigarette lighter. All in all, you'll be amazed at how this washer is such a viable helper - from Sunday car washing to Saturday night party cleanup. Is Convenient Yet Another Adjective? You don't say! Everything you need to get washing on the go is included in the box (ok, not the water): 1 removable water tank, 1 hose, 1 spray gun, 1 power cord, 1 charger, 1 brush head, 1 shower head, 1 adjustable shoulder strap, 4 sealing rings, and 1 manual. But what makes it really convenient is the ergonomic continuous trigger nozzle. When the spray gun is attached, there is no need to pump or crank anything. You simply press the trigger to produce a steady spray, and let go to stop the flow automatically.
