so i bought the wpx3400e and was able to buy the surface cleaner as well. i would say its very hand and light weight. my daughter was able to clean the drive way before mom got home and she was very happy with her freshly cleaned parking space. i am definetly going to have to clean the back drive way this weekend to go ahead and try it my self if my daughter doesnt beat me to it. but yes recommend buy this with your new pressure washer .
