Buy the Roborock Q10 S5+ Robot Vacuum.

It does everything the Shark does, plus the one thing the Shark can't do at all: mop.

What was compared

1. It mops. The Shark just vacuums.
The Shark AV2501S is vacuum-only, no mopping function exists on this model. The Q10 S5+ adds Sonic Mopping with auto mop lift, so spills and daily grime get handled without you touching a mop. Unless you genuinely never want mopping done, the Shark leaves half the floor-cleaning job to you.
2. Empty it once a season, not every month
70-day self-empty capacity against the Shark's 30-day bin means less than half the runway before you're back doing bag duty. For a pet-hair household this is the difference between a quarterly chore and a monthly one.
3. No hair jams choking the brush mid-clean
Roborock built the Q10 S5+ with a Dual Anti-Tangle brush specifically to stop pet hair wrap. Owner reviews of the Shark repeatedly flag clogging and a dust canister that's a pain to clear, exactly the failure mode this design avoids.
4. Fewer repeat passes on carpet and pet hair
Roborock rates the Q10 S5+ at 10,000Pa suction; Shark doesn't publish a comparable number for the AV2501S, and reviews describe it as merely adequate rather than powerful. On carpet and embedded fur, that gap means the Roborock finishes in one pass where the Shark needs two.
5. Yes, it costs more. Buy it anyway.
The Shark undercuts by about $121, but that saving buys a machine that can't mop, empties itself twice as often, and draws clogging complaints in reviews. The extra spend on the Q10 S5+ goes toward capability and lower long-term hassle, not just a bigger price tag.
