We've seen some amazing timelapses from Sunchaser Pictures before: Death Valley Dreamlapse.
But here, they take that same technical prowess and turn it on to a Roomba. Awesome.
Gavin Heffernan of Sunchaser Pictures:
'I recently purchased an awesome IRobot roomba vacuum cleaner (as part of my neverending quest to make household chores tolerable). After watching the cute little circular robot zoom across our floors with endless gusto, I decided to try and attach different lights to the top and shoot some timelapses."
