最后，我们将视线拉回联想的主战场。上世纪八十年代，第一台翻盖式笔记本电脑奠定了现代 PC 的基础形态：一块屏幕，一块键盘，中间用转轴连在一起。在随后的四十多年里，整个行业都在这个框架里打转，把屏幕做得更清晰、把键盘做得更薄、把处理器塞得更满。
UV stain detection is a first for the mainstream robot vacuum industry — the other best robot vacuum and mop combos of 2026 use some combination of LED light sensors and AI camera systems to detect stains. While LEDs are helpful when scoping out wet spills and tiny dry particles, a plain LED bulb won't make an invisible stain glow like it's under a black light (even if it does have the same indigo glow, like the Dreame X60 Max Ultra Complete's blue light). AI mess detection via cameras, like the before-and-after shots that Dyson Spot+Scrub Ai+ takes, can also only go so far if there's nothing visible to take a picture of. Good ol' homegrown UV proof feels much less subjective, much like the reason that I'm so obsessed with Dyson's stick vacuum laser.
