A tough cleaner when you need it. (Amazon/)Pressure washers use high-powered jets of water to blast away dirt and grime, and make quick work of tough cleaning situations like dingy furniture, dirt-caked driveways, and mildewy patios. If your car is a mess, a pressure washer is like having a personal car wash—and it can get into all those crevices for professional-level detailing.

And while the units aren’t light, they’re often attached to frames with whiles for easy mobility.When looking at pressure washers, you want to pay attention to water pressure (PSI) and water flow rate (GPM). Higher PSI machines can knock loose more dirt and grime, while GPM determines how fast you can complete a...
