Shark Detect Pro Robot Vacuum vs iRobot Roomba Plus 515 Combo
Buy the Roomba Plus 515 Combo if you want one machine to vacuum and mop, and you have pets or a mix of carpet and hard floors. Its AutoWash dock washes and hot-air dries the mop pads, lifts them 10 mm over rugs, and its LiDAR mapping avoids clutter. The Shark Detect Pro is a vacuum-only robot with a bagless self-empty base, HEPA filtration and a longer claimed runtime, but no mopping. Owners rate the Roomba higher, though from far fewer reviews.
- Choose the Shark Detect Pro if you only need vacuuming, want HEPA filtration for allergies, and prefer a bagless base.
- Choose the Roomba Plus 515 Combo if you want vacuuming and mopping in one run, with a dock that washes and dries the mop pads.
