3 Things to Know Before Buying a Robot Vacuum

Reliability matters more than features A robot vacuum that actually runs daily is better than a $1,500 flagship that you have to troubleshoot.

Self-emptying is a game-changer If you don’t want to empty the bin every day, get a model that empties itself. Otherwise, a basic model is fine.

Avoid models that get stuck on rugs Look for a vacuum that handles rug tassels and thresholds without getting stuck. The entry-level 600 series does this well.
