(Portland, OR)  --  Sheriff's deputies in Oregon are celebrating a clean sweep in a burglary investigation.  Deputies in a Portland suburb got a call Tuesday from a woman who said someone was locked in her bathroom.  When officers got to the house, they heard what they say were "rustling" noises coming from the bathroom.  The noises became more frequent as they gave commands to surrender.  Officers drew their guns and burst into the bathroom where they found a Roomba robotic vacuum cleaner working away.
