Shark Navigator 2-in-1 Robot Vacuum and Mop vs iRobot Roomba Plus 515 Combo

The Roomba Plus 515 Combo is the stronger pick for most homes because its AutoWash dock handles mop pad washing and its self-emptying base cuts daily hands-on work. The Shark Navigator 2-in-1 is the better fit if you want a simpler, lighter robot that vacuums and mops without a bulky dock. Both carry a 4.8 rating, but the Roomba has more owner reviews behind it, and its voice assistant support with Google, Alexa and Siri is a real convenience edge.

• Choose the Shark Navigator 2-in-1 if you want a straightforward vacuum-and-mop robot without a large self-washing dock taking up floor space.
• Choose the iRobot Roomba Plus 515 Combo if you want a self-emptying, self-washing dock and hands-free control through Alexa, Google Assistant or Siri.
