iRobot Roomba Max 705 Combo vs MOVA E40 Ultra

The MOVA E40 Ultra rates better overall, winning on price, owner ratings, warranty, battery life and suction power. The iRobot Roomba Max 705 Combo wins on connectivity, integrations and cliff detection, and has premium hardware like an AutoWash dock, but owner feedback flags frequent reliability issues that hurt the real-world experience.

Real-world reliability versus platform breadth. The MOVA E40 Ultra runs longer per charge (about 260 minutes versus roughly 75) and pulls more suction (19,000Pa versus 13,000Pa), while the iRobot Roomba Max 705 Combo supports more smart-home platforms, including Apple HomeKit, SmartThings, Home Assistant, IFTTT and Matter, but owners report it failing with errors and leaks more often.

The MOVA E40 Ultra runs far longer, rated for about 260 minutes per charge compared with the iRobot Roomba Max 705 Combo's roughly 75 minutes, meaning the MOVA can cover a much larger area before needing to recharge.

Owner feedback is mixed. Many report frequent issues within weeks, including false bin and water-tank errors, leaking docks, mopping streaks and a buggy scheduling app. When a unit works well, owners praise its LiDAR mapping and AutoWash dock, but reliability complaints are common enough to weigh heavily in any purchase decision.

Apple HomeKit or existing iRobot ecosystem households who want the widest smart-home platform support, including SmartThings, Home Assistant, IFTTT and Matter, and who are willing to tolerate some troubleshooting for its premium self-cleaning roller mop and AutoWash dock.

Buyers who want stronger suction, a much longer runtime per charge and a smoother overall ownership experience, backed by a three-year warranty, even if it means a narrower list of supported smart-home platforms.
