iRobot Roomba 675 vs Shark Matrix Robot Vacuum RV2300

The Shark Matrix is the stronger pick for most homes: LiDAR mapping, room targeting, object avoidance and Matrix Clean's multi-pass grid put it well ahead of the Roomba 675 on navigation and coverage. The Roomba 675 is simpler and lighter, with a larger bin and a long track record, but it cleans in random patterns with no map and no room selection. Both sit at 4.1 stars, and owners of each report the usual robot-vacuum gripes: hair tangling brushes and occasional app or connectivity hiccups.

• Choose the Roomba 675 if you want a light, proven random-navigation vacuum with a bigger bin and you don't need maps or room targeting.
• Choose the Shark Matrix if you want mapped cleaning, room and spot targeting, object avoidance and a pet-hair brushroll.
