iRobot Roomba 105 Combo vs iRobot Roomba Max 705

Here the direction flips from what you might expect: the iRobot Roomba Max 705 is vacuum-only with no mopping at all, yet it still wins this robot vacuum comparison over the mopping-capable iRobot Roomba 105 Combo, on the strength of a self-emptying dock, a much longer roughly 210-minute runtime versus the Combo's 100, dual-band Wi-Fi with Bluetooth, and support for Apple HomeKit, Home Assistant and Matter. The Roomba 105 Combo's one clear edge is mopping, using a water-only pass on hard floors that the Max 705 simply cannot do, alongside a lower price for buyers who want that basic combined function. Neither model dispenses detergent or washes its mop automatically, so the Combo's mopping is the more meaningful differentiator despite its shorter runtime. Buyers who want a self-emptying vacuum-only robot with strong battery life and broad integrations should pick the iRobot Roomba Max 705; those who specifically want mopping alongside vacuuming should choose the iRobot Roomba 105 Combo.
