Our Verdict
Dreame L10s Ultra
Dreame L40 Ultra
While the Dreame L40 Ultra is the higher-end offering to the Dreame L10s Ultra, the L10s Ultra offers superior performance on every surface type. This upset in performance is attributable to the L40 Ultra's pathing, which yields inconsistent results and adversely impacts debris clearing by dragging debris around and insufficiently covering surfaces. That said, if you want a robot vacuum that offers all the bells and whistles and granular customization options, the L40 Ultra is the vacuum for you.
