  1. 3000 psi 2.5 gpi Electric Pressure Washer

    Posted by est0ehp - Pembroke Pines,Florida on 2nd Jun 2021

    This washer was easy to put together and worked
    flawlessly. I installed quick connects on garden hose for fast connect and disconnection. The addition of rotary nozzle was also added for removal of difficult sidewalk cleaning. So far, I'm very satisfied with this electric pressure washer and is strong enough for all cleaning jobs around the house exterior. Great washer for the price!

  2. Powerful, convenient - a great product

    Posted by Hanks - Hendersonville,NC on 2nd Jun 2021

    I have "gone through" 2 electric pressure washers in recent years - the home versions. When I decided to invest for the 3rd time, I decided a professional model was in order and I have no regrets. I had added a 230 volt circuit in my garage some time ago right at the doorway and placed the new pressure washer there. To add to the convenience, I ordered a pressure washer reel and an extra 100 feet of pressure washer hose. To use the unit, all I need to do is to turn on the water supply with a ball valve that I have installed to a 3/4 " line (flow is important), flip the switch on the pressure washer and reel out the hose I need - it;s simple and quick and the unit is amazingly powerful and effective - does a great job. I have used the unit for a year now with no problems - no motor to maintain and considerably quieter than a gasoline model. Absolutely no regrets with this purchase.
