For just $399.99, below its 30-day average of $461.61. The Roomba Plus 405 has been averaging around $482 over the past 90 days, making this current price a meaningful reduction. While not an all-time low. This is one of the better prices we've seen for this model since its introduction.

What You're Getting

The iRobot Roomba Plus 405 Combo delivers both vacuuming and mopping in one device. It features 70x more suction power compared to older Roomba 600 series models, plus spinning DualClean mop pads with SmartScrub technology for deeper cleaning. The AutoWash dock handles emptying, pad washing, and drying automatically for up to 75 days between maintenance. ClearView LiDAR navigation provides precise mapping and obstacle avoidance, while the Roomba Home app lets you customize cleaning routines and monitor progress.

Who This Is For

Best for: Households with mixed hard floors and carpets that want hands-off cleaning. The combo functionality makes sense for kitchens, bathrooms, and living areas where both vacuuming and mopping are needed regularly.

Skip this if you only need vacuuming or already have a dedicated mopping solution.

The Caveat

The AutoWash dock requires regular cleaning solution refills and maintenance. While it reduces manual work, it's not completely maintenance-free.

Those with very large homes might find the battery life limiting for single-session whole-house cleaning.

Final Verdict

At $399.99, the Roomba Plus 405 Combo delivers meaningful value for households wanting both vacuuming and mopping automation. The price undercuts the 30-day average by over $60, making this a practical time to upgrade from basic robot vacuums.

Wait if you need more advanced features like room-specific cleaning schedules or prefer separate vacuum and mop units.
