iRobot Roomba 505X vs MOVA E40 Ultra

Full Robot Vacuums comparison in 2026

Updated September 2026
Data from Amazon and official iRobot and MOVA sites.
2026 verdict
A self-washing mop dock is what both promise, and only one backs it with stronger suction and a longer warranty.
The MOVA E40 Ultra is the stronger robot vacuum and mop overall, better reviewed and running 19000Pa of suction against the iRobot Roomba 505X's 7000Pa, with a three year warranty against the iRobot Roomba 505X's one. The iRobot Roomba 505X answers with Matter support that reaches Apple Home and SmartThings, something the MOVA E40 Ultra does not offer, and its own owners praise precise LiDAR mapping and pet-hair pickup, but a recurring complaint is a loud cleaning cycle. Both empty, wash and dry their own mop pads at the dock. Choose the MOVA E40 Ultra for stronger suction and a longer warranty, and the iRobot Roomba 505X for Apple Home or SmartThings support.

What the differences mean

Suction power

19000Pa against 7000Pa gives the MOVA E40 Ultra a real edge on carpet and pet hair, though its own owners say it still needs turbo mode for tougher debris.

Smart home integrations

The iRobot Roomba 505X reaches Apple HomeKit and SmartThings through Matter on top of Alexa and Google Home; the MOVA E40 Ultra answers only to Alexa and Google Home.

Warranty

The MOVA E40 Ultra carries a three year warranty against the iRobot Roomba 505X's one year, which matters given the mop-pad and motor issues some owners report.

Battery life

260 minutes against 180 gives the MOVA E40 Ultra more runtime before it has to return and recharge.

What owners say

Owners of both robots like how little they have to do once the dock takes over the mop cleaning, though each brand has its own recurring hiccup. iRobot Roomba 505X owners praise precise LiDAR mapping and how well it handles pet hair on hardwood, tile and everyday carpet, but a recurring group finds the cleaning cycle loud enough to schedule runs for when they are out, and a few hit fiddly WiFi pairing or a mapping reset on setup. MOVA E40 Ultra owners are won over by fast, accurate mapping, quiet running and a station routine that empties, washes and dries with little input, and several mention support replacing units without an argument, but multiple owners report the mop pads detaching mid-run, and a smaller group has seen side-brush or motor failures within the first year.
