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.
