Robot Vacuums / Shark
Shark PowerDetect Self-Empty Robot Vacuum (AV2820AE)
Bagless base, no mop, no camera and no Pascal claim — and it still out-vacuums most of them.
Overall score 6.2/10
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
Shark PowerDetect Self-Empty Robot Vacuum (AV2820AE) review: what the specs say
Bagless base, no mop, no camera and no Pascal claim — and it still out-vacuums most of them. At $329.99, Shark's 2024 model sits in the middle of the range — the robot Vacuums we compare run from $139.99 to $1,399.99. It scores 6.2/10 overall, calculated from published specifications across 8 categories rather than from a subjective impression.
Its strongest showing is Running Cost at 9.5/10 — the trap dimension. What the machine costs to feed each year in proprietary bags, mop pads, filters and detergent, and whether a bagless dock lets you spend nothing at all. 10 means it costs nothing to keep running.. The weakest is Mopping at 0.0/10, which is the trade-off to weigh before buying: if that is the specification you care about most, one of the alternatives below will serve you better.
Worth knowing before you buy: no mopping at all — if you want wet cleaning this is the wrong robot; and obstacle avoidance is sensor-based and Vacuum Wars measured it at about half the standard of camera-based flagships. Every specification on this page comes from Shark's own documentation or a verified retail listing — where a figure is not published, the table says so rather than estimating it.

Full Specifications
| 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 |
| 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 |
| 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 |
| What the Maker Promises About Pet Waste | Shark makes no pet-waste avoidance claim for this model |
| Mop System | None. Vacuum only |
| Mop Lift Over Carpet | Not applicable — no mop mm |
| Dock Type & Plumbing | Bagless XL self-empty base with HEPA filtration and odour neutralisation. No water, no plumbing |
| Dock Mop Wash & Dry | 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 |
| Robot Bin Capacity | 227 ml (0.24 qt) onboard — among the smallest here, because the base is meant to do the work ml |
| Rated Runtime (and at what setting) | 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 min |
| 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 |
| Connectivity | Wi-Fi (SharkClean app), Alexa, Google Assistant |
| Material | Plastic; SharkNinja publishes no housing material |
| Warranty | 12 months |
