The Z60 Ultra has no shortage of standout features, but one thing I wanted to showcase is its StepMaster 2.0 system. This allows the robot to lift itself up and hurdle over small steps, door tracks, obstacles, and even U-shaped furniture legs. It can tackle single-layer thresholds up to 1.89 inches tall, or double-layer thresholds up to 3.15 inches, which is pretty impressive. In this test, I’m using a 1.5 inch plank and the Z60 Ultra clears it with ease!
