Every night, before we go to bed, we walk through the house and make sure things are secure.
You know, the doors are locked, the lights are off, and the dog's toys and bones are put away so we don't trip over them in the middle of the night.
There's something else to add to the list now... your robot vacuum!
Yana Sydnor of Sacramento heard “boom boom booms” over her meditation music at 1 in the morning.
The sound was coming from downstairs, so she called police.
They busted down the door, expecting to find a burglar.
What they found was Yana's robot vacuum, cleaning the floor. She hadn't used it in 2 years!
No, it's not a ghost in the machine... her son had decided to turn it on, because he didn't want to do his chores before he left for the weekend!
