iRobot Roomba 105 Combo vs Shark Navigator Robot Vacuum

The Roomba 105 Combo is the more versatile machine: it vacuums and mops, lifts its mop on carpet, and maps with LiDAR. The Shark Navigator is the simpler, stronger vacuum-first pick, with HEPA filtration, a self-cleaning brushroll and a bagless base rated for about 60 days of debris. Owners rate the Shark slightly higher, but on far fewer reviews. Buy the Roomba for mixed hard floor and rug homes that want mopping; buy the Shark for carpet-heavy homes that only need vacuuming.

• Choose the Roomba 105 Combo if you want one robot to vacuum and mop, and you have a mix of hard floors and rugs it must tell apart.
• Choose the Shark Navigator if your home is mostly carpet and you want stronger suction, HEPA filtration and a brushroll that resists hair wrap.
