Disappointed

3 days ago
This is my second PowerShot, and I am disappointed. First, the carriage has been redesigned to eliminate the shelf behind the motor. Second, the fuel filter and gasket were missing. Third, the soap dispenser is not working so I will have to take it apart to see if the ball is stuck.

Great Pressure Washer

3 days ago
I bought this pressure washer and couple months ago and am glad I did. It's easy to start, powerful, and comes with everything you need to get started. It's already tackled several large cleaning jobs around my property. I would recommend it to anyone.

Great Powerwasher!

3 days ago
I’ve been very happy with my Simpson power washer. It starts easily, has plenty of power for cleaning decks, siding, driveways, and equipment, and feels well-built. The pressure is strong enough to tackle tough dirt and grime, yet it’s easy to operate. Overall, it’s a reliable machine that gets the job done and has been a great investment for home and outdoor cleaning projects.
