Roborock Saros Z70 review: If you think you need the robot vacuum with an arm, no you dont

There has been one pressing question about the Roborock Saros Z70 since it was announced at CES 2025: Could a robot vacuum with a robotic arm possibly be a practical purchase for a normal person? The Saros Z70 takes the "robot" in robot vacuum to a whole new level. Past referring to the brains of the automated cleaning operation, "robot" also refers to a whole ass robotic arm that unfolds from the vacuum to move pesky obstacles out of the way. This is cool in theory for anyone whose home has random stuff lying around on the floor at any given time, but the practicality bubble is quickly burst when you realize that the Saros Z70 costs 2,599. That's a full 1,000 more than Roborock's other two CES flagship releases, the Saros 10 and 10R, that I also happen to have at home right now. Multiple friends who have come over recently have literally laughed in my face when I told them that one of those three costs 2,599.
