Robot vacuums can self-clean and self-navigate, which is why they are often unsupervised while on the job. Should they be left alone in a bedroom, would they still be able to clean underneath the bed without dust ruffles stopping them?

Given that robot vacuums come in different sizes, so do their dustbin capacities and how much dirt they can hold. Although often left unnoticed, the dustbin capacity of a robot vacuum is an important feature that needs to be considered before making a purchase.
