Today, the company announced that on May 27th, it will reveal when its Cyber X bionic quad-track stair-climbing system will launch and, presumably, how much it will cost. The robot that can transport a robot vacuum up a flight of stairs will arrive alongside three new X60 Pro series robots, the most intriguing of which features Dreame’s first dual-joint bionic robotic arm that can extend a mop pad into tight corners and under furniture.
