## What reviewers found

### Dreame Matrix10 Ultra

- Vacuum Wars (3.65/5): Lab tests found 80% sand removal from carpet, 92% flattened pet hair pickup, 0% hair wrap, 19 of 24 obstacles avoided and a combined mopping score of 29 against a 22 average; coverage was about 757 sq ft per charge against a 1,117 sq ft average and crevice pickup was weak. [Source](https://vacuumwars.com/dreame-matrix10-ultra-review/)
- TechRadar: Mapped a large village hall and open plan home accurately and mopped hard floors with no streaks; carpet results were good but left more debris than expected in a heavy debris test, and the app was slow and overwhelming. [Source](https://www.techradar.com/home/robot-vacuums/dreame-matrix10-ultra-review)

### Roborock Saros Z70

- Vacuum Wars (3.17/5): Lab tests found top tier mopping with a combined score of 269 against a 171 average and 22 of 24 obstacles avoided, but only 67% sand removal from carpet and 83% pet hair pickup; the arm worked about half the time. [Source](https://vacuumwars.com/roborock-saros-z70-review/)
- TechRadar: Vacuuming was excellent on carpet and lino and mopping strong at edges, but the arm had no fully successful autonomous pickup and the review unit rattled while cleaning. [Source](https://www.techradar.com/home/robot-vacuums/roborock-saros-z70-review)
- Android Authority: Called it Roborock's best robot vacuum so far for navigation and cleaning, but the arm set socks and paper beside the bin rather than in it and does not justify the price over the Saros 10R. [Source](https://androidauthority.com/roborock-saros-z70-review-3558359)
