## 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)

### iRobot Roomba 105 Vac + AutoEmpty Dock

- Vacuum Wars (1.41 Vacuum Wars stars): Removed 82% of embedded sand, above the 75% average, but picked up only 29% of flattened pet hair and 79% of long hair wrapped the brush. Coverage was about 630 sq ft per charge and it has no obstacle avoidance. [Source](https://vacuumwars.com/roomba-105-vac-review-irobots-cheapest-self-emptying-robot-vacuum-in-2025/)
- RTINGS: Named the Roomba 105 its best cheap robot vacuum for smart navigation, long battery life and an optional self empty dock, but called vacuuming only adequate and obstacle avoidance weak. [Source](https://www.rtings.com/robot-vacuum/reviews/best/budget)
