## What reviewers found

### Dreame D20 Air Plus

- Android Authority: Tested at home over several runs: cleaned about 400 sq ft in 48 min on 80% battery, then about 463 sq ft in 57 min on 73%. Navigation was good, but it shoved angled leg items and folded a small mat. Mop works only as a damp touch up. Given the AA Recommended badge, no numeric score. [Source](https://androidauthority.com/dreame-d20-air-plus-review-3705125)
- PCWorld: Tested in a split level home on hard floors and rugs: good vacuuming for the price, picked up greyhound hair, cleaned under a low entertainment center and finished a downstairs area in about 33 min with 77% battery left. It repeatedly nudged a mat and the mop is basic. [Source](https://www.pcworld.com/article/3191770/dreame-d20-air-plus-review.html)

### eufy 11S Max

- TechHive: The jump to 2,000 Pa lifted more crumbs and pet hair, especially on carpet, and it crossed carpet to hardwood smoothly. It navigates by driving straight and turning on contact, so cables should be tidied. [Source](https://www.techhive.com/article/583831/eufy-robovac-11s-max-review.html)
- The Ambient: Removed most of the dirt in its runs and was very quiet in standard mode, but with no app or mapping it bounced around at random, choked on cables and got wedged between chairs. [Source](https://www.the-ambient.com/?p=11324)
- Mighty Gadget (87%): Left a full bin after each room and rarely caught on cables; the reviewer did not run formal suction tests. [Source](https://mightygadget.co.uk/?p=24993)
