Awesome until it stopped working
First, this thing was huge.  The pictures don't really depict how big they are.  Super strong motor but stopped spraying after 1 week.  Used Virex.  When it worked it was great; heavy, definitely needs a single shoulder strap.  Louder than I thought it would be.  I really wanted these to work but tried everything to see what was blocking the flow but found nothing.  Sent both back.  One was more than enough for our 15,000 sq ft fitness center.  Definitely hard on the hand and wrist especially if trying to spray higher level areas / awkward to lift
