Genius!
A vacuum cleaner that learns your house and goes out each day to pick up small bits and pieces it finds on the ground.
Set this machine up and let it do it thing.
It will trace around his house without needing anything from him. When its batteries are low it goes back to its little home and props itself onto its charger. When charged up it gets out there and does its thing again.
