When a terrified Oregon woman heard weird noises and saw shadows coming from her locked bathroom, armed officers were called in and they prepared to break down the door to neutralize the suspect. Deputies surrounded the house, brought in a canine unit and shouted to the suspect to exit the bathroom or face the consequences. The cops heard “rustling” noises, USA Today reports, which became more frequent as they continued to shout instructions to their suspect. But when the door remained closed for 15 minutes, they burst in with their guns drawn—and found a Roomba. The Washington County Sheriff's Office said in Facebook post Tuesday that officers discovered a “very thorough vacuuming job being done by a Roomba Robotic Vacuum cleaner.” Good job, everyone.
