Hard start

Would Not Recommend

It’s hard to start when cold. Someone has to hold the handle. When it is hot, it’s hard to start. Wish I never bought it.

Seems like a good pressure washer.

Would Recommend

I have only used a couple times but has worked great. The only issue is the nozzle hose is to close to the hot stuff. Put a hole in the hose the 2nd use. Started using wire ties to keep the new hose away from the heat. There needs to be a 90 degree fitting coming out of the supply pump.

DO NOT BUY

Would Not Recommend

This pressure washer never worked out of the box. It will crank and run but never builds up water pressure. I received it on a Wednesday and didn’t use it until Saturday and Lowe’s wouldn’t take it back because they have a “48 hr return policy”. So I’ve had to deal with Westinghouse to try and fix it and it’s been a nightmare. They won’t let me return it and insist that I need to tear it apart to diagnose the issue. I’ve been dealing with it for over a month now! Buyer Beware!
