Okay, you got us. The main reason why we had to upload this picture is because of the cute doggo. Just look at that proud grin on his face, as if he cleaned the backyard all by himself. Apparently, the OP’s previous washer broke, so he went out and bought a new one and managed to clean his entire backyard.
It was probably the combination of a powerful new washer along with his determination to clean that yielded such amazing results. Who knew there was even a dog under all that muck? Seriously, though, that look of approval on his face is everything.
