[Source](https://www.techradar.com/home/robot-vacuums/dreame-aqua10-ultra-review)
- Expert Reviews: Tested the UK Aqua10 Ultra Roller Complete: excellent vacuuming and mopping, but it took almost twice as long as a Eufy E25 to clean the same 21 m2 floors, used 75% battery on a four room run and got stuck more than the reviewer liked.
