How they differ in real use
Built from our robot vacuum cleaners scoring, each product's published specifications, and verified owner feedback — not hands-on testing.
Both the iRobot Roomba 205 DustCompactor Vac and the Shark UR2500SR AI Ultra Robot Vacuum made our Top 5 Robot Vacuum Cleaners, at #2 (best value) and #4. The eufy C10 that previously held this spot is now out of stock everywhere, so a newer, cheaper stablemate of the Roomba 105 Vac above takes over: the Roomba 205 Vac skips a separate dock entirely, compacting debris inside the robot itself for up to 60 days of hands-free cleaning. It matches the 105's 7,000 Pa published suction at a lower price, though independent reviews found its navigation less dependable and its compactor mechanism messier in homes with heavy pet shedding. LiDAR navigation with bagless self-empty base (30-day capacity, no consumable bags). Pa suction not disclosed, penalized under the scoring rubric.
