The Dreame L40 Ultra offers acceptable performance in a multi-surface household. It does a passable job on bare floors, effectively handling larger debris but missing fine and medium particles as well as patches of floor due to its inconsistent pathing. It's a little better on carpet, though it leaves debris along edges and in corners. Its brushroll doesn't provide enough agitation to deal with fine material in carpet, which also shows in its poor pet hair cleaning performance. Thankfully, its obstacle handling is good despite its odd pathing behavior—it does avoid almost every object it encounters. The full-featured station is pretty good, too, handling most daily maintenance tasks. Its mopping results are acceptable, and it would be better if the pathing were more efficient.
