iRobot Roomba Combo i5 vs Shark Navigator Robot Vacuum

Pick the Roomba Combo i5 if you need one machine to vacuum and mop hard floors, and you want a low-profile robot that fits under furniture. Pick the Shark Navigator if you have carpets and pets and want stronger suction, a self-cleaning brushroll and better owner ratings. The Roomba's mopping is a swap-in bin, not a lift-and-drop system, and its 3.4 rating from 74 owners is weaker than the Shark's 4.1 from 281. The Shark does not mop despite some listings saying so, and its taller body limits where it fits.

• Choose the Roomba Combo i5 if you want vacuum and mop in one robot and need it to slide under low furniture.
• Choose the Shark Navigator if your home is mostly carpet with pet hair and you want stronger suction and a tangle-resistant brushroll.
