Roborock has come a long way from its first generation of clunky robot vacuums that got stuck in corners or blindly bumped into furniture. One of their latest innovations is the Saros Z70, which CNET calls an “AI-powered housekeeper.” It has a robotic arm that allows the device to tidy while it cleans, picking up items like socks and slippers and moving them to designated areas. Right now, the Roborock Saros Z70 robot vacuum and mop is half off, at an all-time low price of $999.99 (originally $1,999).

While the star of the show is the robotic appendage on this AI-powered robot vacuum-and-mop hybrid, it also offers a range of other features, including 3D navigation, a self-emptying bin, automatic mop washing and drying, and built-in voice control. The Omnigrip arm finds, marks, and lifts obstacles to clear once-blocked areas: First, it cleans the rest of the room, then returns to move obstacles and clean the now-uncovered spot. Plus, it has a weight limit, so it won’t accidentally try to pick up pets or heavier, permanently placed items.

The Saros Z70 has 22,000Pa of suction power and hot-water mopping, and 30 adjustable water flow levels. It has dual cameras to enhance navigation and precision sensors to lift itself (climbing thresholds up to about 1.5 inches). Its 3.14-inch profile helps it fit under low-profile furniture. The battery life is around two hours and 15 minutes without the arm; Roborock says it can clean around 150 square meters with the arm enabled, moving up to 10 items.
