Rated 5 out of 5 by from Easy to Use I just bought this as a replacement for one I bought over two years ago. We use it at work to spray disinfectant as a covid precaution. It works great and lasted 2.5 years of daily use.

Rated 2 out of 5 by from Air in Sprayer expanded and Broke! I filled the container up with wet it and forget it and used it for spraying my roof to get rid of the moss and algae. It's not a pressure washer, so it's not a powerful spray. The spray is comparable to a hand sprayer and saves having to pump it up. Finished with the roof spraying, I climbed down the ladder and set the sprayer on the ground. If I were to stop here, I would give it a 5. The problem: When cleaning up, I went to pick up the sprayer, and the tank fell off. I then notice that the cap was broken into a number of pieces, and one of the plastic clips on the motor part of the sprayer that holds it to the tank broke. It was hot that day, and the sprayer was in the sun. So I think what happened is that the air in the tank expanded, broke the lid, and shattered the cap. They are made of hard plastic, not rubbery plastic. Again, it was hot but certainly not as hot as if I had set it down on the roof or asphalt driveway. I would think there should be a relief valve built into the tank to limit the pressure and release any excess amount of pressure that could build up due to the air in the tank expanding. I could get a new cap and bungee cord the tank to the motor part, but I think I will return it to Home Depot. If I do get another one, I will be sure to unscrew the top to release the pressure before setting it down, and when I store it, I will be sure to leave the cap loose.
