iRobot Roomba 105X vs MOVA E40 Ultra comparison

Updated July 2026

Data from Amazon and official iRobot and MOVA sites.

2026 verdict

Cliff detection and a lower price are genuine wins for the iRobot Roomba 105X, but they are also its only wins against the MOVA E40 Ultra in this robot vacuum comparison, which pulls ahead on rating, warranty, battery life, smart-home integrations and mopping thanks to a station that empties, washes and hot-air dries its own mop pads. Both use laser navigation with obstacle detection, multi-room mapping and no-go zones, so day-to-day coverage is close; the real gap is maintenance, since the Roomba 105X has no mopping, no self-emptying and needs its bin emptied by hand. The MOVA E40 Ultra also runs longer between charges and backs its extra automation with a 3-year warranty. Buyers who want a hands-off, all-in-one station that vacuums and mops in the same run should pick the MOVA E40 Ultra; anyone who mainly needs simple, mapped vacuuming with dependable cliff detection at a lower price can stick with the iRobot Roomba 105X.

Frequently Asked Questions

Which is better overall: the iRobot Roomba 105X or the MOVA E40 Ultra?
