Source verdict

The reviewer concludes that the Dreame X50 Ultra is "easily one of the best robot vacuums we've ever tested" and a strong contender for the best robot vacuum of the year. It ranked number three on their top 20 robot vacuum list at the time of the video, with potential to reach number one if its price decreases.

About this source

This review evaluates the Dreame X50 Ultra, a new flagship robot vacuum and mop combo, detailing its features and performance across various tests. It covers basic vacuuming, mopping capabilities, navigation, obstacle avoidance, and battery life, culminating in its ranking on a curated list of robot vacuums.

Review notes

The Dreame X50 Ultra is an outstanding flagship robot vacuum that excels in cleaning performance and innovative features, making it a strong contender for best robot vacuum of the year. Its new duo brush system delivered perfect scores in pet hair pickup and significantly improved deep cleaning on carpets, extracting 83% of embedded sand, well above the 75% average. The robot also showcased superior threshold crossing, clearing a 36mm board, and boasts a smart retractable lidar for improved navigation under low furniture. Despite its strengths, its suction and airflow bench test results were merely average, though this did not impact real-world cleaning performance. If you prioritize cutting-edge cleaning technology, advanced navigation, and comprehensive mopping with dock self-cleaning, this vacuum is an excellent choice. However, if raw suction power for specific crevice cleaning is your primary concern, you might want to consider alternatives.

What the reviewer liked

  • New duo brush system excels at hair pickup (0% tangle) and deep cleaning (83% sand removal)
  • Superior threshold crossing ability, clearing up to 36mm (and rated for 42mm)
  • Retractable lidar sensor allows it to get under low furniture (89mm clearance)
  • Automatically extending mop pad for improved edge coverage
  • Mop pads automatically lift over 10mm when sensing carpets or can be left at base
  • Dock features hot water mop washing, hot air drying, and auto water refill
  • Newly designed ACE dry board self-cleaning system in the dock prevents clogging
  • Above-average obstacle avoidance using camera-based and 3D structured light system
  • Excellent mapping and navigation efficiency with perfect coverage
  • Above-average battery life (6,400 mAh)
  • Feature-rich app with voice assistant, Matter support, smartwatch compatibility, and granular control

What the reviewer criticised

  • Average suction and airflow in bench tests
  • Lackluster performance in crevice pickup test on max power
  • Higher-end price point
