Rated 4.7 out of 5 by 11 reviewers.
Rated 5.0 out of 5.0 by grate product had an earlier model worked good. this one a little better, more comfortable. September 16, 2015
Rated 4.0 out of 5.0 INCOMPLETE ASSEMBLY In order to make it work, the $49.99 part becames $100. You have have to buy an extention\ adapter and a pack of 4 nozzles in order to have a complete and working unit that is ready to install and go to work. Don't expect much knowledge from the associates in order to help you figure out the hardware needed to get it done. April 28, 2013
Rated 5.0 out of 5.0 by Love my pressure washer My pressure washer was so easy to connect, works fabulous. I am looking for things to clean! It is so easy to use. June 16, 2015
Rated 5.0 out of 5.0 by i bought this as a replacement to one that an employee lost, i have since replaced all of the guns i use in my company with this one, i and my employees no longer get what we call "claw hand" since the switch. very comfortable to use October 11, 2010
Rated 5.0 out of 5.0 by Pricey but Good This replaced a cheaper gun that broke. Used it several times and it's a nice gun.Comfortable to use and seems to be well constructed. Time will tell. As mentioned in a previous review, if you don't have a wand and tips, add another 40-50 bucks tom the cost for a complete gun ready o use September 2, 2013
Rated 5.0 out of 5.0 by It's the Cadillac A little heavier than your average wand but that good construction yields a great feeling tool that saves you from that " I'm beat up" sensation when used an extended amount of time. September 9, 2011
Rated 5.0 out of 5.0 by This sprayer is well built. The sprayer is for heavy duty use. The side handle provides extra control for the force created by this sprayer. I bought a short extension and it makes this easier to control and not as wobbly when longer extenmsions are used. December 6, 2011
Rated 5.0 out of 5.0 by Cat Pumps Pressure Washer Gun Needed quality replacement handle for pressure washer and tried this one based on other reviews. This is a very high quality handle and is nice to use, plus it is made by a quality company. I guess hot water capability is nice, but not sure I'll ever own a hot water pressure washer. May 14, 2012
