iRobot Roomba 505X vs MOVA E40 Ultra

Price, rating and a three-year warranty all favor the MOVA E40 Ultra over the iRobot Roomba 505X, and it also runs longer per charge, about 260 minutes against 120. Suction is published on the MOVA E40 Ultra at 19,000Pa (iRobot does not publish a figure for the 505X), and its MaxiReach mop extends up to 4cm into corners other robots miss. The iRobot Roomba 505X answers with wider smart-home reach, adding Apple HomeKit, Samsung SmartThings, Home Assistant and Matter plus 5GHz WiFi and dedicated cliff detection, a safety feature the MOVA's spec sheet does not list; both robots otherwise self-empty, wash and dry their mop pads automatically and share the same LiDAR mapping and no-go zones. Worth knowing before buying the MOVA E40 Ultra: several owners report mop pads detaching mid-run and a handful describe side-brush or motor failures within the first year, issues the iRobot Roomba 505X's own feedback does not raise. Buyers chasing the lowest price, the longest runtime and the longest warranty should pick the MOVA E40 Ultra; buyers who want the broadest smart-home support and cliff detection should pick the iRobot Roomba 505X instead.
