Robot vacuums can easily clean flat surfaces without much fixing and monitoring needed from a user's end. However, can robot vacuums still complete a cleaning cycle when there are different threshold heights and uneven floors?

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.
