Simpson 60869 PowerShot 4000 PSI 3.5 GPM Professional Gas Pressure Washer with AAA Triplex Pump (CARB)

We previously owned two pressure washers, one of them more powerful than the other, but neither of them prepared us for the cleaning power of this machine. It starts on the first pull, and the pump puts out a powerful stream of water at a good flow rate. We have a home with a long concrete drive and a large concrete patio. In Florida, this means mildew and algae. This pressure washer puts out enough water and a high enough pressure to effective clean even the worst areas. We bought a commercial grade surface cleaner and this machine puts out enough water at enough pressure to use this effectively. This is a powerful machine that makes cleaning so much easier. We love it.
