If you want a robot vacuum that’s all about vacuuming performance (and not a mop combo), the iRobot Roomba Max 705 is my top pick. It pulled up a surprising amount of dirt, crumbs, hair, and fine rug fibers, and the self-empty base can hold up to 75 days of debris in a sealed bag.
Pros
+Auto-empties into a sealed bag that can hold up to 75 days of debris
+Strong suction and excellent pickup on hard floors and carpets/rugs
+Learns room layouts quickly and navigates around furniture and obstacles well
+Smooth transitions from hard floors to rugs
+Sleek, high-end look with more natural-sounding voice announcements
