Mid Plus model: spinning mop pads and a heated AutoWash dock, but plain ClearView LiDAR without PrecisionVision AI or Dirt Detect, so it maps well and identifies clutter far less reliably.
The iRobot Roomba Plus 515 Combo scores 88/100 on the Robot Autonomy Index (RAI), RobotSniper's 0–100 measure of how little human help a robot needs across navigation, obstacle avoidance, automation, and self-maintenance. That puts it in the Highly autonomous tier — excellent everyday autonomy with a capable dock. Occasional human input, but rarely. The sweet spot for most buyers.
