What was supposed to be an hour or two for testing turned into a successful 12-hour cleaning project with the Dewalt 20V MAX 550 PSI power cleaner kit.

The MAX 550 hooks up to a garden hose with a quick connect adapter, delivering 10 times the water pressure you'd get from the hose alone. Four quick-release nozzles are included; wider nozzles produce a gentler wash, while narrower ones produce greater pressure. An attachable soap bottle is included.

For power, a rechargeable 20V MAX XR DCB205 battery (5.0Ah) is included with a charger. Like any gadget that runs on batteries, it's a good idea to get a second one. The battery connects to the power washer in a plastic watertight compartment. A storage bag is included.

Initially, my thinking was this would be good for minor cleaning, but with the portability, there's so much more you can do without having to pull anything around besides a garden hose. My 12-hour mission took me from my back patio to window moldings, gutters, even taking spiderwebs off shrubs. There were small stops here and there on stuff I'd never put 2,400 PSI of water pressure, such as outdoor furniture and car bumpers.

A suction hose is included, which I used to connect with a 5-gallon bucket for some simple tasks. (dewalt.com, $199 for kit, $149 for washer alone)
