Pet owner questions about it
Does it scatter hair on hard floors?
A fast brush roll on tile throws light fur ahead of the nozzle. Soft rollers and scatter-free settings exist to stop that. The Bissell lists a scatter-free mode; Dyson's fluffy head does the same job by running a soft roll instead of a stiff one.

Will a robot vacuum run over pet accidents?
Supervise the first week of runs. Once you have watched it steer around a few obstacles, running it with the house empty stops feeling like a gamble.
