There are plenty of other good things about them, but before we dive in let’s consider the biggest trade-offs: less power, less capacity and less flexibility. Those first two go hand in hand; robot vacuum cleaners are much smaller than upright vacuums, which leads to less powerful suction. They also hold less dirt because their built-in bins are a fraction of the size of a standard vacuum canister or bag. Fortunately, some models include features like an auto-empty station, which helps with dirt capacity, especially in homes with pet hair.
