Dreame L40 Ultra

The reviewers bought and tested it, found it an outstanding, feature-rich vacuum and mop that matches the pricier X40 for less money, ranks second on their top list, and has hair tangling as its main weakness, which the optional Tri-cut brush largely fixes.

A feature-rich, well-built premium robot vacuum with strong obstacle avoidance and a capable dock, but erratic pathing and weak agitation make its cleaning on carpet, fine debris, and pet hair mediocre, and it is outperformed by several rivals.

4.5/5

A highly capable self-cleaning robot vacuum and mop with excellent navigation, obstacle avoidance, pet hair handling and mopping, held back mainly by its bulky, unattractive dock and the existence of cheaper rivals, but still very good value for what it offers.

A powerful, flexible robot vacuum and mop that excels at deep mopping, suction and smart obstacle avoidance, with only minor quirks around carpet settings, edge cleaning and overly granular options.

9/10

The writer found the L40 Ultra to be one of the best robot vacuums they have used, with strong navigation, mopping and automation, and recommends it for nearly anyone who can afford the high price despite weaker suction than some rivals.

The writer sees the L40 Ultra as a top-tier robot vacuum and mop that performs almost as well as the flagship X40 Ultra for noticeably less money, though it is still expensive and slow to clean thoroughly.
