The DirtSpotter concept was arrived upon by considering what the vacuum cleaner would be like in 20 years time.
DirtSpotter
Group project The DirtSpotter lightbulb functions as both a source of light and a cleaning aid. It scans the room for the areas most in need of cleaning, and at the changing of the switch, projects onto the surfaces of the room which areas are the priority for cleaning. A speculative project, aimed first at hospitals and labs, but it could also be of use in a domestic setting.
