For just $399, below its 30-day average of $488.94. This price sits $100 below the 90-day average and nearly $100 under the 180-day trend. While not a record low, it's a meaningful drop from where this model has been selling for months.

What You're Getting

The Roomba Plus 405 combines vacuuming and mopping in one robot with an AutoWash dock that handles emptying, pad washing, and drying. It uses LiDAR navigation for precise mapping and cleaning in neat rows, even in dark rooms. The dual spinning mop pads provide deeper scrubbing with downward pressure, and they automatically lift when sensing carpet. The system offers 75 days of auto-emptying and 4 weeks of mopping between maintenance cycles.

You control everything through the Roomba Home app for custom cleaning routines and room-specific attention.

Who This Is For

Best for homeowners who want hands-off floor maintenance without separate vacuuming and mopping sessions. This works well for mixed flooring homes with both hard surfaces and carpets.

The Caveat

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

Those in small spaces might find the dock's footprint larger than expected.

Final Verdict

At $399, this combo robot delivers automated vacuuming and mopping for under $400. The price beats recent averages by nearly $100, making it a practical upgrade from basic robot vacuums.

Move now if you want to eliminate both sweeping and mopping chores this spring.
