What the differences mean

Suction

The MOVA E40 Ultra is rated at 19000 Pa, nearly three times the 7000 Pa of the iRobot Roomba Plus 505. On carpet and pet hair that is the gap you would notice first.

Battery

The MOVA E40 Ultra runs 260 minutes and the iRobot Roomba Plus 505 180. In a large home the MOVA is more likely to finish without stopping to recharge.

Smart home

The iRobot Roomba Plus 505 supports Matter, Apple Home and SmartThings as well as Alexa, Google Home and Home Assistant. The MOVA E40 Ultra stops at Alexa, Google Home and Home Assistant.

Warranty

Three years for the MOVA E40 Ultra, one for the iRobot Roomba Plus 505. Owners of both report failures after a few months, which makes the longer cover worth having.

What owners say

Owners of both robots credit fast LiDAR mapping and strong pet hair pickup, and both groups name the station's washing and emptying routine as the reason they bought it. MOVA E40 Ultra owners add quiet running and value, especially on sale, but report mop pads falling off mid-run, side-brush and motor failures within months and slow support escalation. iRobot Roomba Plus 505 owners like running vacuum and mop together or apart on a schedule, and warn about a dock self-cleaning cycle that sounds like a washing machine, bumper-stuck or docking errors a few months in and warranty trouble when the robot was bought from a third-party seller.
