To be fair, the only advantage a robot vacuum has is that's it's unattended - it's pretty much a worse vacuum in every way than a regular one; limited range/time, poor suction, gets stuck, etc. The idea is that it will do a mediocre job of cleaning often enough that dirt doesn't build up. Even with the issues, I feel like my Roomba is still a net gain, but it's not a slam-dunk.
