Out of all the pressure washers on the market today, the Karcher K5 Premium Pressure Washer is one of the best pressure washers from the Karcher lineup. 

Living in Seattle, moss buildup is inevitable during the rainy season. And let’s face it: it rains in Seattle almost year-round. It’s almost always rainy season. Moss made my front porch and driveway look unclean and messy. 

I used many products and many ways to remove moss, dirt, and grime from my driveway and other areas around the house. If I could go back in time, I would have used the Karcher K5 pressure washer. There are so many uses for a pressure washer that I didn’t realize that would help homeowners keep their homes looking clean and sharp. Here is the Karcher K5 Premium Pressure Washer review.
