Bounties attract serious brainpower to the challenge.
You may have watched the movie, iRobot which stares Will Smith where robots literally planned to wipe off human race. That is scary but, we can't stop this moving train.
Robot vacuums never get bored or distracted, and they don’t mind working every day. In most homes, they keep the floors tidy with barely any effort—pet hair and crumbs disappear before you even notice a mess.
These robot vacuum are great and they have solved the problem of cleaning for humanity... Well, not too much.
I say this because we still need to shift obstacles and rearrange them. If we still need to help the vacuum in this regard, then, there is need for a solution.
I think there should be an innovation that gives robot vacuum the ability to lift and shift obstacles to allow for total vacuuming of an area with a robotic arm without human assistance.
There should be a camera and sensor system that gives the robot the ability to assimilate the arrangement of a room. There could be a way whereby a choice arrangement may be saved to the robot's setting by the purchaser.
This memory would allow the robot to re-arrange a room after thorough cleaning.
However, this would mean that robot vacuums will be large in size and I can therefore not help but imagine a situation where there is a system malfunction.
This would be nightmarish or at best like a chaotic scene in a Sci-fi movie.
