The eufy is a vacuum and mop whose dock empties the bin, washes and dries the roller mop and doses detergent, it reaches every major smart home platform through Matter, and it is rated for 179 minutes against 110 on the Shark PowerDetect Self-Empty. What the Shark owns is simplicity and price: it is the more affordable of the pair, it skips water altogether, and its NeverStuck lifting and bagless HEPA base keep a pet home clean with nothing to leak. Pick the eufy Omni S2 for hands-off vacuuming and mopping in one machine, and the Shark PowerDetect Self-Empty if you want a cheaper, fuss-free vacuum-only robot.

What the differences mean

Mopping

The eufy Omni S2 vacuums and mops, and its dock washes, dries and doses the roller mop. The Shark PowerDetect Self-Empty has no mopping hardware at all, which is the whole reason to choose it only if your floors never need water.

Dock and emptying

The eufy Omni S2 self-empties into a 2.5 L dock bin and handles the mop for you. The Shark uses a bagless HEPA base rated for up to 30 days of debris, so it asks for less maintenance but also does less.

Battery

The eufy Omni S2 is rated at 179 minutes per charge and the Shark PowerDetect Self-Empty at 110. On a large floor plan that gap is real, since the Shark needs a top-up sooner.

Smart home reach

The eufy Omni S2 works with Alexa, Google Home, Apple Home, SmartThings, Home Assistant and Matter. The Shark PowerDetect Self-Empty stops at Alexa, Google Home and Home Assistant, with no Apple Home or Matter.

Suction

The eufy Omni S2 is rated at 30,000 Pa. Shark does not publish a Pascal figure for the PowerDetect Self-Empty, so the specs cannot settle the comparison on suction.

Warranty

The eufy Omni S2 carries two years and the Shark PowerDetect Self-Empty one. Given both rely on a dock and moving parts, the longer cover favors the eufy.

What owners say

Owners of both robots are happiest about the same job: keeping ahead of pet hair and daily dust. eufy Omni S2 owners add that the roller mop lifts ingrained mud and that the dock empties, washes, dries and doses on its own, but several report navigation and app trouble on complex layouts, a tall 98 mm body that misses low furniture and occasional unit errors. Shark PowerDetect Self-Empty owners stress a different point, that it almost never strands itself and that its taller body no longer wedges under furniture, while their complaints settle on a basic SharkClean app, awkward Wi-Fi pairing and missed patches. What the Shark group does not discuss is mopping, because there is none.
