Shark Matrix Plus 2-in-1 Robot Vacuum & Mop vs iRobot Roomba Plus 515 Combo

The Roomba Plus 515 Combo is the stronger pick for most homes. It self-empties, washes and hot-air dries its mop pads, refills its own water tank, lifts pads 10 mm over carpet, and maps with LiDAR, so it runs for months with little handling. The Shark Matrix Plus 2-in-1 is a simpler, lighter-duty machine: it vacuums and mops, has a HEPA filter and a removable battery, but it lacks a self-cleaning dock and LiDAR mapping. Owners of the Roomba line praise the hands-free dock and tangle-resistant brushes; the Shark suits smaller spaces and buyers who want HEPA filtration and a swappable battery.

• Choose the Shark Matrix Plus 2-in-1 if you want HEPA filtration, a removable battery you can swap or replace, and a lighter robot for a smaller home with mostly carpet.
• Choose the Roomba Plus 515 Combo if you want a dock that empties, washes and dries the mop pads and refills water, plus LiDAR mapping and pad lift for mixed carpet and hard floors.
