- 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.

- Tom's Guide: Picked up 100% of cereal and kitty litter on carpet and 70% of pet hair on carpet, but mopping left floors streaky and patchy and the pads fell off once crossing a cable. [Source](https://www.tomsguide.com/home/home-appliances/roborock-saros-20-review)
