Shark PowerDetect Self-Emptying Robot Vacuum (AV2820S) review

The PowerDetect AV2820S brings Shark's detect-and-react features to a vacuum-only robot. Four technologies work together to target hidden dirt, boost cleaning along edges, adjust to each floor type and keep the robot from getting stuck, and NeverStuck Technology physically lifts and lowers the robot to cross thresholds and obstacles. When the battery runs low it returns to the base, recharges and resumes where it stopped. Each run ends with a self-empty into a bagless base that holds 30 days of debris, and the base's HEPA filtration traps 99.97% of dust and allergens down to 0.3 microns, per Shark, with Odor Neutralizer technology for pet smells. The problem is price: at $549.99 with no discount shown, it costs as much as the mop-washing NeverTouch Pro's sale price and $220 more than the Matrix RV2310AE. Its base is also the smallest here, and Shark's page showed no customer reviews yet. We compared documented features and published prices.
