I have always had gasoline powered pressure washers, my current one is a 3400 PSI 2.4GPM unit. When I couldn't get it started after refilling the gas in the middle of the job, I bought this one. It does an amazing job given its specifications. No, it isn't enough to run my commercial floor cleaner, but it came with one that does a great job. It also came with a foam cannon, but I haven't tried that yet. The best part is I can set it up and my wife can run the thing on her own. Much quieter than a gas unit, and starts on demand. The gas units may be more powerful, but if it won't start it doesn't matter.
