The Roomba Max 705 Combo still wins on connectivity and integrations, adding 5GHz Wi-Fi, Apple HomeKit, Home Assistant, IFTTT and Matter support that the Omni C28 does not list, and its extending self-cleaning roller mop and AutoWash dock are strong ideas when the unit performs as intended, though it has a documented history of reliability complaints. Both are self-emptying combos with LiDAR navigation, multi-room mapping and no-go zones, so the day-to-day cleaning routine looks similar on paper. Buyers deep in the Apple or Matter ecosystem who are comfortable troubleshooting occasional issues may still want the Roomba Max 705 Combo's feature list, but anyone who wants a more consistently dependable combo with stronger battery life and suction should choose the Eufy Omni C28.
