Dreame L40 Ultra — where it shines
The L40 Ultra is a near-top-tier system: strong suction, dual spinning mops that extend outward to scrub baseboards and corners, hot-water mop washing, and a fully automated dock that empties, washes, dries, and refills. It cleans edges better than most rivals. The downsides are the steep price, a large dock, and an app that can feel overloaded with settings.
