Shark Detect Pro Self-Empty Robot Vacuum vs iRobot Roomba Combo j7+

Pick the Shark Detect Pro if you want the strongest vacuuming and the cleanest air: HEPA filtration, a bagless base that holds about 60 days of debris, LiDAR mapping, and three sensors that boost suction and clean edges. Pick the Roomba Combo j7+ if you want one machine to vacuum and mop, and you have carpets next to hard floors, because its mop pad lifts up onto the robot so carpet stays dry. The Shark rates higher with owners (4.5 vs 4.1) and runs longer per charge, but it is heavier and does not mop. The Roomba is lighter and simpler to lift, but its filter is not HEPA and its battery lasts about 90 minutes.

• Choose the Shark Detect Pro if you have pets or allergies and want HEPA filtration, self-emptying, and the deepest clean on carpet and edges.
• Choose the Roomba Combo j7+ if you want to mop hard floors and vacuum in one pass without wetting the carpet.
