Shark AV2501S AI Ultra Robot Vacuum — A Thoughtful, Balanced Review
First Impressions and Design
Right out of the box, the Shark AV2501S exudes a modern aesthetic: a dark-grey body with minimalist clean lines, crowned by a compact LiDAR turret—hinting at its keen navigation capabilities. Setup couldn’t be simpler: snap on the two side brushes, plug in the self-emptying base, and you’re ready to map and clean your floors.
The low profile (about 4.1″ tall) lets it glide under beds and sofas with ease. The build feels solid, though the LiDAR housing’s glossy surface may scratch more easily than I’d like.

Intelligent Navigation & Mapping
Equipped with 360° LiDAR vision, the Shark AI Ultra creates precise maps of your home that support room-based scheduling and targeted cleaning—even in low light or complete darkness.
Matrix Clean Navigation enhances this further by breaking rooms into grids and making multiple passes to ensure no area is left untouched—no more missed corners or random zig-zagging.
Power, Runtime & Auto-Empty Convenience
Under the shell sits powerful Shark suction that tackles dirt, debris, and pet hair on both hard floors and carpets with confidence. Voice control through Alexa and Google Assistant, as well as the SharkClean app, adds modern convenience.
Most striking is the bagless, self-emptying base—no messy dustbags to swap out. It holds up to 30 days of debris (some variants even offer 60-day capacity). A built-in True HEPA filter locks in 99.97% of dust and allergens, keeping the air clean while emptying.
Battery life extends up to 120 minutes, with intelligent Recharge & Resume for long cleaning sessions, enabling whole-home coverage.
Real-World Performance: Wins and Woes
Wins:
-
Hard Floors & High-Pile Carpets: Excellent suction. Picks up cereal, dirt, and light debris with minimal fuss.
-
Upside for Allergies & Pet Owners: HEPA filtration and sealed disposal make this model stand out for capturing fine dust and pet dander.
-
Quiet and Efficient: Runs smoothly and distributes cleaning intelligently without loud disruptions.
-
Happy Users: Many customers love the mapping accuracy, self-emptying, and minimal maintenance. On Best Buy, it holds a solid 4.4 out of 5 from over a thousand reviews.
“It does everything it promises. Unlike my first vacuum, the Shark rarely gets stuck. It makes a perfect mapping … schedule when to run it automatically.”
Challenges:
-
Struggles with Low-Pile Carpet & Pet Hair: Multiple reviews noted that the vacuum tends to push hair deeper into low-pile fibers instead of lifting it out—leading to repeated runs.
-
No Mop Option: Unlike 2-in-1 models with mopping, this variant is vacuum-only.
-
Dock Capacity & Hygiene: While convenient, the bagless base can be messier to clean compared to bagged models, and demands occasional manual clearance—especially if pressed daily.
Comparison Snapshot
Compared to Shark’s own Matrix Robot, the AI Ultra holds its own for pet-hair sealing and runtime—but the Matrix model recharges faster and does better on low-pile carpets and app integration.
Reviewers outside Shark’s ecosystem emphasize that while the AI Ultra is feature-rich, more polished experiences from Roborock or Yeedi may offer smoother navigation and overall performance—though often at higher prices or with the trade-off of less effective allergen sealing.
Final Thoughts: Is It Worth It?
If you’re shopping for a smart, low-maintenance vacuum that handles everyday debris, supports voice/app control, keeps allergens locked down, and rarely needs emptying—the Shark AV2501S AI Ultra is a compelling option. Its thoughtful design minimises effort, and its mapping/navigation is on point.
However, if your home features a lot of low-pile carpet or you’re chasing every bit of pet hair, you may need to run it multiple times or consider models optimized for that (e.g., with stronger agitation or mop options). Still, for what it is—a highly capable vacuum that lets you automate routine cleaning—it’s a strong performer in its mid-tier class.
Summary Table
| Feature | Strengths | Considerations |
|---|---|---|
| Suction & Coverage | Excellent on hard floors & high-pile carpets | Low-pile carpets & pet hair require repeat runs |
| Navigation & Mapping | Precise LiDAR, Matrix grid cleaning | None notable |
| Self-Empty Base | Bagless, 30-day, HEPA-filtered | Slight mess when emptying; capacity less than bagged models |
| Runtime & Resume | 120 min with recharge & resume | — |
| Allergen Control | HEPA-based system sealed during disposal | — |
| App & Voice Control | Smart scheduling, room targeting, voice enabled | Some users report occasional connectivity hiccups |
| Design & Maintenance | Sleek build, easy-access parts | LiDAR surface prone to scratches, maintenance for brushes |

Final Verdict
The Shark AV2501S AI Ultra Robot Vacuum is a smart, reliable cleaning companion tailored for those who value convenience and cleaner air. Its LiDAR-based Matrix Clean navigation is methodical and thoughtful—ensuring full-room cleaning, even in the dark. The real hero, though, is its self-emptying, bagless base with True HEPA filtration—a rarity that significantly reduces maintenance and locks down allergens your family breaths in.
Performance is very strong on hard floors and high-pile carpets. Pet hair and low-pile carpet performance is adequate, but not stellar—expect to run extra cycles. If expert-level carpet fiber extraction is your top priority, you might consider specialized models or hybrid units, but many households still find the AI Ultra’s automation and allergy control make up for the occasional extra pass.
Compared to other Shark models, it stands out in runtime and sealing capability; versus competitors like Roborock and Yeedi, it balances performance and value—especially for homes focused on cleaner air and less maintenance.
In sum: for busy homes, pet owners, allergy sufferers, or anyone who wants to set it, forget it, and come back to clean floors with healthier air—this Shark model is a worthwhile, genuinely convenient robot vacuum. Just don’t expect it to be a mop or a low-pile carpet specialist.
Hope this deep dive helps you—or anyone else—make an informed choice.
