## 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)

### Roborock Q7 M5+

- Tom's Guide: Tested the Q7 M5 robot without the dock: 93.3% overall pickup on tile and 85% on carpet, with 70% of pet and human hair on carpet. Human hair caught on the brush roll and the mop only handled light dirt. [Source](https://www.tomsguide.com/home/smart-home/roborock-q7-m5-robot-vacuum-review)
- TechRadar: Called the Q7 M5 a brilliant budget bot with accurate mapping and strong pet hair pickup, but it hit every test object, long hair still wrapped the brush and the app had several glitches. Subscores: Value 4/5, Performance 4/5, App 3.5/5. [Source](https://www.techradar.com/home/robot-vacuums/roborock-q7-m5-robot-vacuum-review)
- Vacuum Wars (2.01 Vacuum Wars stars): Above average suction and navigation speed, but average results on embedded sand (75%) and flattened pet hair (79%), 43% hair wrap, and heavy water use when mopping. [Source](https://vacuumwars.com/roborock-q7-m5-and-m5-review/)
