Not necessarily: if you have a small apartment with open floors and no pets, a basic robot may suffice, but if you have kids, pets, many corners, or visible baseboards, strong edge cleaning saves you from chasing dust bunnies.What are the alternatives to a side brush for edge cleaning?

Some cheaper models rely only on the main roller and suction, often leaving a gap; a few high-end robots use cameras or lasers to drive closer but still miss the last half inch without a brush.
