Deputies in Portland, Oregon responded to a possible home invasion, but the intruder they found wasn't alive or a person.
It was a robotic vacuum cleaner.
A house sitter called 911, saying someone was inside the bathroom.
Deputies opened the bathroom door with guns drawn and discovered the automatic vacuum cleaner.
Sgt. Danny DiPietro says this encounter was his first "Roomba burglar" in 13 years on the job.
