iRobot Roomba Combo i5 vs Shark Matrix 2-in-1 Robot Vacuum & Mop

The Shark Matrix is the better pick for most homes. It vacuums and sonic-mops in one pass, maps with 360 LiDAR, has a self-cleaning brushroll and a HEPA filter, and its 4.0 rating from over 1,600 owners is far stronger than the i5's 3.4 from 74. The Roomba Combo i5 is lighter and shorter, runs up to 180 minutes, and works with Siri as well as Alexa and Google, but you swap in a separate Combo Bin to mop, and owners report weaker pickup and mapping. Buy the i5 only if you want a low-profile robot under furniture and long runtime on mostly hard floors.

• Choose the Roomba Combo i5 if you need a slim 3.6-inch robot that fits under low furniture, want up to 180 minutes of runtime, and use Siri alongside Alexa or Google.
• Choose the Shark Matrix if you want true simultaneous vacuum-and-mop, LiDAR mapping with object avoidance, a self-cleaning brushroll for pet hair, and a HEPA filter.
