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 105 Vac Robot Vacuum with AutoEmpty Dock and the iRobot Roomba 205 DustCompactor Vac made our Top 5 Robot Vacuum Cleaners, at #1 (best overall) and #2 (best value). eufy discontinued the L60 in October 2025 with no restocks planned, so the Roomba 105 Vac takes the top spot as the new suction leader: 7,000 Pa published suction, ClearView spinning-LiDAR navigation, and a 2.5 L AutoEmpty dock lasting ~75 days, the longest self-empty interval in the dry-only class. 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.
