Quick Verdict
A 0.9-point gap makes the Shark PowerDetect Self-Empty Robot Vacuum (AV2820AE) the straightforward choice here. Bagless base, no mop, no camera and no Pascal claim — and it still out-vacuums most of them.
The Shark PowerDetect Self-Empty Robot Vacuum (AV2820AE) and eufy RoboVac 11S MAX (T2126) are both closely matched robot Vacuum models, and the eufy RoboVac 11S MAX (T2126) is $190 cheaper than the Shark PowerDetect Self-Empty Robot Vacuum (AV2820AE) ($139.99 vs $329.99). On Dock Automation, the Shark PowerDetect Self-Empty Robot Vacuum (AV2820AE) leads (5.5 vs 1.0/10) — how much the dock genuinely does unattended: self-empty, hot-water mop wash, hot-air dry, solution dosing, plumbed refill and drain — minus the jobs it still leaves you.. On Privacy & Control, the eufy RoboVac 11S MAX (T2126) leads (9.0 vs 5.5/10) — whether an account and cloud are required, where the maps live, whether there is a camera and where its frames are processed, and the brand's actual privacy and security record.. On Carpet Cleaning, the Shark PowerDetect Self-Empty Robot Vacuum (AV2820AE) leads (8.0 vs 5.5/10) — embedded-debris and pet-hair pickup from carpet in independent bench tests, plus anti-tangle brush design — not the manufacturer's Pascal claim..

Side-by-Side Comparison
| Spec | Shark PowerDetect Self-Empty Robot Vacuum (AV2820AE) | eufy RoboVac 11S MAX (T2126) |
|---|---|---|
| Price | $329.99 | $139.99 |
| Release Year | 2024 | 2019 |
| Claimed Suction (Pa) | Shark publishes no Pascal figure for this robot at all. It markets DirtDetect and NeverStuck instead, which means nothing on this row is comparable to the five-digit Pa claims from the Chinese brands — and Shark still out-cleans several of them | 2,000 Pa claimed by eufy. Sources conflict: TechGearLab's spec table for this same model lists 1,300 Pa, which is the figure for the older non-MAX 11S. Either way the number is a marketing figure, not a measurement you can compare across brands |
| Independent Test Result | Vacuum Wars placed it in the top 10 of 100+ robots tested for crevice pickup and well above average on carpet deep clean, but kept it out of the Top 20 purely because it does not mop | TechGearLab: 90% hard-floor debris pickup, 6.8/10 carpet, but 3.4/10 for navigation and obstacle avoidance. Overall 55/100, 18th of 23 robots tested |
| Navigation & Obstacle Avoidance | Spinning LiDAR turret, maps in roughly 10 minutes. Front obstacle detection is a 3D sensor plus dual lasers; Vacuum Wars rates it at roughly half the effectiveness of flagship camera systems | Bump-and-turn random navigation. Front bumper and infrared cliff sensors only — no LiDAR, no camera, no map, no no-go zones |
| What the Maker Promises About Pet Waste | Shark makes no pet-waste avoidance claim for this model | eufy makes no pet-waste claim for this model and it has no camera, so it cannot see waste at all |
| Mop System | None. Vacuum only | None. Vacuum only |
| Mop Lift Over Carpet (mm) | Not applicable — no mop | Not applicable — no mop |
| Dock Type & Plumbing | Bagless XL self-empty base with HEPA filtration and odour neutralisation. No water, no plumbing | Charging base only. No self-empty, no water, no plumbing |
| Dock Mop Wash & Dry | Not applicable | Not applicable |
| Dock Bags & Running Cost | $0 a year in bags — the base separates into a removable tray you tip into the bin. The only recurring parts are the base HEPA filter (rinse every 1-2 months, replace every 6-12) and side brushes, against roughly $26-32/yr in bags for the Roborock and iRobot docks | No bags at all, so $0/yr in dock consumables. Recurring parts are a washable filter, a rolling brush and side brushes; eufy and third parties both sell refill kits for the 11S/15C/30 family |
| Robot Bin Capacity (ml) | 227 ml (0.24 qt) onboard — among the smallest here, because the base is meant to do the work | 600 ml, emptied by hand every 2-3 runs |
| Rated Runtime (and at what setting) (min) | About 100-110 minutes from a 3,200 mAh cell. Vacuum Wars flags the small battery as the main limitation in large homes: it will need multiple charge-and-resume cycles | Up to 100 minutes — eufy's figure is Standard mode on hard floor. BoostIQ on carpet cuts it |
| Account, Cloud & Camera Privacy | SharkClean account and app required and maps are cloud-stored. No camera on the robot. Vacuum Wars calls the app buggy and notes it still lacks room-specific scheduling | No account, no cloud, no camera, nothing leaves the house. The price is no map, no zones and no scheduling beyond the remote's daily timer |
| Warranty | 12 months | 12 months |
| Colors | Black | Black, White |

Pros & Cons
Shark PowerDetect Self-Empty Robot Vacuum (AV2820AE)
Pros
- +The bagless base is the single biggest running-cost saving in this category — no bag ever, for the life of the robot
- +Top-10-of-100 crevice pickup and above-average carpet deep clean in Vacuum Wars' bench tests, at around $330
- +No camera and no water tank: nothing to spy with, nothing to go mouldy
- +NeverStuck chassis genuinely reduces the rescue-the-robot calls that plague cheap LiDAR machines
Cons
- −No mopping at all — if you want wet cleaning this is the wrong robot
- −Obstacle avoidance is sensor-based and Vacuum Wars measured it at about half the standard of camera-based flagships
- −3,200 mAh battery and ~110 minutes is short for a big house
- −SharkNinja publishes no suction figure, no airflow figure and no dock noise figure, so paper comparison is impossible
- −Retail SKUs are confusing: AV2820S ships a 30-day base and AV2820AE a 60-day XL base at similar money — check which one you are buying
eufy RoboVac 11S MAX (T2126)
Pros
- +Under $150 street with no app, no account and no Wi-Fi — there is genuinely nothing to sign up for
- +90% hard-floor pickup in TechGearLab's test, better than the price suggests
- +72 mm tall, so it clears kick-boards and bed frames every dock-equipped robot here is too fat for
- +Zero proprietary consumables: no bags, no pads, no detergent — the cheapest robot here to keep running
Cons
- −A 2019 design still on sale in 2026 — bump navigation means no map, no no-go zones and no memory of where it has been
- −TechGearLab scored navigation and obstacle avoidance 3.4/10; it eats cables and strands itself
- −eufy's 2,000 Pa claim is unverifiable and TechGearLab's own spec table records 1,300 Pa for the same robot
- −No mop and no self-empty base — you empty a 600 ml bin by hand every two or three runs
- −Street price swings between roughly $140 and the $279.99 list, so buying at list is a bad deal
