The 13 most useful smart home devices I’ve seen at CES 2026 (and would buy if I could)

The Navimow X4 is Segway’s newest flagship robot mower, announced at CES 2026. This powerful robot mower requires no RTK antenna or boundary wire; instead, it uses advanced technology that combines sensors, cameras, and LiDAR to navigate. The X4 also has an all-wheel drive (AWD) system that can handle inclines as steep as 84% or 40 degrees. 

The X4 robot mower features an entirely different design from its predecessor, departing from what had almost become Navimow’s signature rounded design. Instead, the Navimow X4 features the same racecar look that was popularized with the Mammotion Luba 2, a design that other brands, including Roborock, have since adopted. The X4 is beginning pre-orders on January 16, starting at $2,499 for the X430, which covers up to 1 acre, and $2,999 for the X450, which covers up to 1.5 acres.
