But it is also newly released with no established track record of owner feedback yet, while the Dreame D30 Ultra CE has thousands of reviews behind its rating. The Dreame D30 Ultra CE also holds more water and more debris in both its onboard bin and dock, runs longer per charge, typically costs less, and carries a three-year warranty against one year on the Roborock Saros 20 Sonic. If raw suction and the newest smart home protocols matter most and you don't mind being an early adopter, the Roborock Saros 20 Sonic is the pick; for proven tank capacity, battery life and warranty coverage, the Dreame D30 Ultra CE wins.
