Roborock Q5 Max+ vs. Shark AI Ultra: Two Self-Emptying LiDAR Robots, One Slim Edge
In the $400 range, the Roborock Q5 Max+ and Shark AI Ultra are almost the same robot on paper: LiDAR mapping, a self-emptying dock, and no mop. Both scored identically across our four axes, so anyone shopping this bracket ends up comparing them head to head. The gaps between them are narrow — but they matter, and they sit in less obvious places than the spec sheet suggests.
The short answer
Pick the Roborock Q5 Max+ if you find it cheaper on the day: the engine scores them level on every dimension.
Pick the Shark AI Ultra (AV2501S) if the budget is the constraint — it does the same job for $30 less.

Suction on paper vs. cleaning on the floor
The Shark lists more suction, and it is easy to read that as more cleaning power. It is not. Pascal ratings climb fast and deliver little past a point; a few hundred Pascals between two mid-tier robots is marketing margin, not a performance gap. Our engine agrees: both land at the same cleaning score. Expect competent pickup on hard floors and low-pile carpet from either, with the usual LiDAR-robot struggles in corners and along baseboards. Neither is a deep-carpet specialist.
Navigation: same score, two different philosophies
Both use LiDAR to map and route logically, and both earn the same navigation score, so neither gets lost or bumps its way around the room. The flavor differs. Roborock leans on mapping precision and a mature app — flexible no-go zones, room-by-room routines, and reliable multi-floor maps. Shark counters with Matrix Clean, a back-and-forth grid pattern that re-covers a zone for a more thorough single pass. One prioritizes control; the other prioritizes coverage on the spots you point it at.
Dock, mop, and where the value tips
Here the two are twins: each empties itself into a base, and neither mops, so wet-cleaning buyers should look elsewhere. That leaves the ecosystem and the price. The Shark undercuts the Roborock by a small margin — real money at this tier. The Roborock asks a little more and returns it in software maturity: a more flexible app and a longer track record of firmware support and mapping reliability. Whether that premium pays off depends on how much you plan to live in the app.
Choose the Roborock Q5 Max+ if…
- Nothing in the scored data favors it — the Shark AI Ultra (AV2501S) matches or beats it on every dimension and does not cost more
Choose the Shark AI Ultra (AV2501S) if…
- Costs $30 less: $400 against $430
Verdict
This is close, and the scorecard calls it a tie — but most buyers should take the Roborock Q5 Max+ for its more mature app, mapping flexibility, and support track record, especially if you will lean on multi-room or multi-floor routines. Choose the Shark AI Ultra if you want to save the difference and like its Matrix Clean zone pattern, and you are fine with a slightly less refined app. Neither mops and both empty themselves, so if you need wet cleaning, neither belongs on your list.
Still not sure?
Answer a few questions about your space and how you will use it, and the engine narrows the whole catalog down to the robot vacuum that fits.
