I am very please the results after I connected it to my pressure washer and used it to wash my front porch and driveway, even the siding along the front porch. It not only cleaned very well, but also efficient, i.e., much less time and water, compared to two years ago when I used only the pressure washer for the job.
This surface cleaner saved me hours in pressure washing pool deck, patio & walkways not to mention the back ache after just using a spray wand previous years. This surface cleaner also eliminates the streaking from just using a wand.
Works well on concrete driveway, tile patio floor and around texture pool decking floats well without catching on rough surfaces. I did have to go over a couple of stained areas with a 15 degree head to clean up spots and to wash dirty water down driveway or off patio. I have the Westinghouse 3000E, PW and the 14” wand is to short for me (6’1””) a 16” extension would be nice to have available to buy. However, my old P.W. had a 31” wand so I used that one
