- Gizmodo (3.5/5): Cleaned a 750 sq ft apartment in just under two hours with over 50% battery left.

- 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)
