Shark Matrix Self-Empty Robot Vacuum vs LiDAR Robot Vacuum and Mop Combo

The Shark Matrix is the stronger pick for carpeted homes and pet hair. It self-empties for about a month, uses LiDAR mapping with object detection, and has a self-cleaning brushroll that resists hair wrap. The generic robot vacuum and mop combo adds mopping, which the Shark lacks, but it gives up the self-empty base and the documented navigation and brushroll features. Owners rate the Shark well on suction and hair pickup; the combo's sparse listing leaves its build and reliability unproven.

• Choose the Shark Matrix if you have carpets, pets, or a lot of hair to pick up and want a base that holds debris for weeks.
• Choose the robot vacuum and mop combo if hard floors dominate your home and you want one machine to vacuum and mop.
