iRobot Roomba Max 705 vs Shark PowerDetect ThermaCharged RV2920XE

Here the mop tips the scales: the Shark PowerDetect ThermaCharged RV2920XE is the stronger robot vacuum in this comparison, largely because it mops with a self-washing, self-drying dock, something the iRobot Roomba Max 705 does not do at all, and it backs that up with a longer two year warranty and the more consistently positive owner rating of the two. Where the Roomba Max 705 pulls back ahead is smart home breadth: it adds Apple HomeKit, Home Assistant, IFTTT, Matter and 5GHz Wi-Fi to its list, none of which the Shark offers, since the Shark tops out at Alexa, Google Home and 2.4GHz Wi-Fi only, and its 210 minute runtime edges out the Shark's 180 minutes. Both use LiDAR navigation with no-go zones and multi-room mapping, so the real decision is mopping versus platform breadth and a longer single charge. If hard floors need washing as well as vacuuming and platform breadth is not a priority, the Shark PowerDetect ThermaCharged RV2920XE is the stronger choice; if your home runs on Apple HomeKit or Matter, or you want the longest possible single-charge runtime and never plan to mop, the iRobot Roomba Max 705 is the better fit.
