The iRobot Roomba Plus 505 Combo is the better choice for users seeking advanced performance and minimal intervention. Its PrecisionVision AI enhances obstacle avoidance (20/24 vs. 16/24), and the PerfectEdge mopping system provides superior edge cleaning, while the heated dock drying prevents odors, making it ideal for busy or pet-heavy homes. The slightly higher suction (~7,500Pa) and future AI updates further justify its ~$799 price.
The Roomba Plus 405 Combo, at ~$699, offers strong value with similar core features—LiDAR navigation, dual spinning mops, and an AutoWash dock—but its lack of camera-based obstacle detection and heated drying leads to more manual oversight and less precise cleaning. Its carpet performance (72%) lags behind the 505’s (78%).
For budget-conscious buyers with simpler layouts, the 405 Combo is sufficient, but the 505 Combo’s advanced navigation, mopping, and dock features make it the smarter investment for long-term convenience and efficiency.
