Third-party reviews

Reviews last updated: July 2026 · How we calculate this

What customers like about Shark AV2820AE

  • Bagless self-emptying base saves money in the long term.
  • Excellent cleaning performance on hard floors and carpets, including pet hair.
  • EdgeDetect technology uses bursts of air to improve cleaning along edges and in corners.
  • DirtDetect automatically increases suction when dirt is found.
  • Strong LiDAR navigation and smart features.

What customers don't like about Shark AV2820AE

  • The mobile app can be glitchy and offers limited customization.
  • Mapping is not always as accurate as competing systems.
  • Air blown along edges can sometimes scatter dust instead of collecting it.
  • Limited options for scheduling multiple cleanings in a single day.
  • Advanced room-mapping features could be improved.

Verdict

The Shark PowerDetect Self-Empty Robot Vacuum (Model AV2820AE) is a cordless smart vacuum equipped with 360-degree LiDAR navigation, a 3D sensor for obstacle avoidance, and a 650-watt motor that runs for up to 100 to 110 minutes on a 6-hour charge. Main characteristics include a 0.23-litre on-board dust cup paired with a bagless self-emptying base that holds up to 60 days of debris, a self-cleaning brush roll featuring anti-hair wrap technology, and integrated LED lights. Key pros include its multi-sensor intelligence: DirtDetect which automatically increases suction in heavily soiled areas, EdgeDetect which uses air blasts to clear debris from corners, and NeverStuck technology that actively lifts the body over obstacles up to 20mm tall. The base also provides excellent health benefits through an Anti-Allergen Complete Seal trapping 99.9% of particles and an Anti-Odour cartridge to prevent foul smells. However, notable cons include lackluster battery life on high-power modes, below-average obstacle avoidance that occasionally struggles with smaller hazard recognition, slightly weak deep-cleaning performance on fine debris embedded in thick carpets, and limited customization options within a sometimes buggy companion app.
