Dreame X50 Ultra

The reviewers bought and tested it, and call it one of the best robot vacuums they have evaluated, with standout pet-hair pickup, strong obstacle avoidance and a highly automated dock, held back only by average suction and a flagship price.

A pricey but standout robot vacuum-mop that excels at obstacles, pet hair and object avoidance thanks to its climbing arms and tangle-free roller, though it is not the best pure vacuum on carpet and is only a strong value at a discount.

A premium, very capable robot vacuum with standout edge cleaning, mopping and low maintenance, held back by short real-world battery life, imperfect object avoidance and a high list price.

A top-tier flagship robot vacuum and mop that handles pet hair and navigation very well, with only minor issues like occasional snags and mopping streaks, and not worth upgrading to if you already own the X40 Ultra.

A pricey but outstanding flagship robot vacuum whose strong vacuuming, mopping and automation make it one of the best available, though it is slow, drains its battery and still needs floors kept tidy.

A powerful, highly flexible robot vacuum and mop that can climb thresholds up to 6cm and slip under low furniture, delivering excellent cleaning and navigation for challenging homes, though it is expensive and has overly many mop wetness settings.
