Roborock Saros Z70
Tap a star to rate
The OmniGrip arm is unlike anything else in this guide: a foldable, five-axis mechanical arm with its own camera, LED light, and precision sensors, capable of judging an object's position and weight before gripping it and setting it aside. It genuinely picks things up, a stray sock, a phone charger cable, light clutter, rather than just steering around them the way every other robot in this roundup does.
Underneath the novelty is a serious cleaning machine: 22,000Pa suction, a dual all-rubber brush design that resists tangling, and StarSight 2.0 navigation building spatial awareness from more than 21,600 data points at high frequency. At 3.14 inches, it's also Roborock's thinnest robot to date. It's priced at the very top of the market and best suited to someone who has struggled with floor clutter interrupting cleaning runs and wants the most advanced obstacle handling available today, not someone shopping on value.
