Not what I expected but... [SEP] When I ordered this, I thought it was a regular ol' hose nozzle.  It's not -- you can actually attach it to a pressure washer as well.  I was not overly impressed with this at first.  The pressure washer attachment came connected to the hose nozzle and it was an absolute pain to remove (my husband had to use pliers to get it out).  It was easy enough to attach to the hose but somewhat a pain to take off.  It also only seems to have 2 spray patterns, not 4 like advertised (a hard "line" spray and a softer line spray).<br /><br />I was not comfortable spraying my flowers with this because it seemed to spray fairly hard, even when I turned the nozzle to reduce the spray.  So, I started spraying off the mold on my sidewalk.  Our house faces north and is fairly shaded in the front and, since it rains a lot in Florida, tends to get mold build-up on the front sidewalks.  As you can see from the picture I posted, this nozzle does actually help spray off mold.  It's not quite a pressure washer but it was able to remove the heavy stuff (but, remember, it does come with the pressure washer attachment).  I am giving this four stars because it's not quite what I expected but it does help remove mold from cement, which makes it worth having.
