The top three pressure washers for 2015 are the Generac 6598, AR Blue Clean AR383, AR Blue Clean AGR118, as stated by ConsumerSearch. The models are judged based on cleaning adjust-ability and ease of use.
The Generac 6598 features a 3,100 psi pump and gas powered engine. It has an array of tips available, which allow for different levels of pressure to be used, according to ConsumerSearch.
The AR Blue Clean series are both electric. These units are not as powerful as the Generac, however they do contain pumps that are capable of producing up to 1,900 PSI. Each unit has several different tips that can be fitted to the hose end, which limit the amount of exit pressure.
