iRobot Roomba Plus 505 vs MOVA E40 Ultra

Cheaper, better rated, longer warrantied and stronger on both battery and suction: the MOVA E40 Ultra beats the iRobot Roomba Plus 505 across nearly every measured spec in this robot vacuum comparison, running 260 minutes per charge against 120 and pulling 19000Pa against 7000Pa, backed by a 3-year warranty against 1. It is not a clean sweep, though, and the gap that's left matters: the MOVA E40 Ultra's cliff detection is not documented, while the iRobot Roomba Plus 505 confirms it, worth knowing if you have stairs, a raised hearth, or open landings the robot needs to stay away from. The Roomba Plus 505 also keeps a real edge in smart home reach, connecting to Apple HomeKit, Samsung SmartThings, Home Assistant and Matter, all of which the MOVA E40 Ultra lacks, and its 5GHz Wi-Fi support is confirmed where the MOVA's is not. Both wash and dry their own mop pads and empty their own bin, and both use Laser (LiDAR) navigation with multi-room mapping and no-go zones, so day-to-day cleaning automation is close between them. Buyers focused on runtime, suction and price should lean toward the MOVA E40 Ultra, but anyone with stairs or drop-offs to protect, or who wants Apple HomeKit and Matter support, should stick with the iRobot Roomba Plus 505.
