## At a glance

- DirtDetect is described as sensing hidden debris and automatically increasing suction, the listing also says it can increase cleaning passes.
- EdgeDetect is described as using air blasts to draw debris from edges and corners into the cleaning path.

- NeverStuck is described as lifting and lowering to move across thresholds and obstacles, including onto thick carpets.
- The listing describes a bagless self-empty base with a HEPA anti-allergen seal and claims a 30-day capacity.

## Pros

- The listed detection features target different cleaning situations: hidden debris, edges and corners, and changes in floor type.
- The claimed self-emptying base is bagless and described as having a HEPA anti-allergen seal, which may reduce routine bin-emptying and dust handling.
- The listing provides both button and app control, with Amazon Echo named as a compatible device.

## Before you buy

- The advertised pickup and edge-cleaning improvements are comparisons against specific Shark models and test conditions, so they do not establish results against other vacuums or in every home.
- Listing details are inconsistent: it specifies a corded-electric power source alongside a 110-minute battery life and lithium-ion battery, and gives dimensions of 20.08"L x 13.39"W x 11.81"H with a weight of 1.8 pounds, confirm these specifications for the AV2820S. The 30-day base capacity is a stated claim, not a guaranteed interval.

## In the box

- Side brush (Included): Listed as an included component.

## A good fit for

- Buyers seeking a robot vacuum whose listed features address carpets, hard floors, pet hair, and edge debris may find the detection-focused approach relevant.
- Households interested in reducing manual bin emptying may value the claimed bagless self-empty base.

## Less suited to

- Buyers who require clearly confirmed power and runtime specifications should resolve the corded-power and battery-life inconsistency before choosing this model.
- Those who need consistently precise mapping, uncomplicated app control, or reliably quiet operation should consider the reported mixed feedback on those areas.

## Customer feedback

Customer feedback highlights positive reports about cleaning floors and pet hair, as well as ease of setup and use. Experiences are mixed on value, mapping coverage, target areas, and noise, some report fast mapping while others say it misses parts of a floor or does not go under furniture, and noise is described as varying from relatively quiet to very loud on the max setting. App usability is also described negatively. These reports matter because the product's listed LiDAR and detection features do not guarantee complete coverage or a smooth app experience. The aggregate rating is 4.0 out of 5 from 610 global ratings, with 62% five-star and 15% one-star ratings, those figures show a spread of ratings but do not identify why individual customers rated it as they did.
- Positive themes: Customer feedback describes effective floor and pet-hair cleaning and says setup and use are easy.
- Negative themes: Customer feedback describes the app as clunky.
- Mixed feedback: Feedback varies on value, mapping and target-area coverage, and noise, reports range from easy mapping and relatively quiet operation to incomplete coverage, difficulty navigating under furniture, and loud noise on the max setting.
