Great balance of performance/ quality and price!

This is the third power washer I have owned in the past 25 years. I always bought what I felt was a good value at one of the big box stores —but after the last one gave out, I decided to see if the more powerful power washers could fit within my budget / quality /performance ‘sweet spot” . The Westinghouse WPX 4400 pressure washer is very well made with quality parts. The larger engine, controls, and up to 4000 PSI means it can clean in one to three passes - which used to need 5 to 8 times of going over the same spots. I am happy I have this well designed and manufactured Westinghouse product!
