Excellent product

This is my first pressure washer and I decided to get this particular one because it offered commercial quality at a reasonable price. This is built so well, it will be the first and last pressure washer I will need to buy. It was very gratifying to clean the filthy sidewalk in my front yard with this machine.

I got this as a residential model for cleaning bare concrete. It’s beyond powerful enough. For the price, you will not find more cleaning power. If your looking for a washer to regularly use on a car, I would suggest something with less power, this has taken small bits of paint off of my car.

No problems after 20 hour run time.

Bought this unit 2 months ago. I’ve had no problems with it after 10 jobs. Plenty of power! A quick squirt of the wand releases line pressure to pull start. If it doesn’t start on first pull, release line pressure again. When starting, don’t put your foot on air stem of tire, it will break.
