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.
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.
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.

The X50 Ultra had a lackluster showing on crevice pickup tests at max power, which the reviewer attributes to the new dual brush design creating a larger opening that diluted suction.

The Dreame X50 Ultra was significantly better than average in the 2.5-inch pet hair pickup test on carpet, achieving the best score the reviewer has seen for a combo robot. It also picked up 83% of deeply embedded sand in the carpet deep clean test, surpassing the 75% average.
The X50 Ultra features a new tapered duo brush system that channels hair to prevent tangles. In a 7-inch hair test, it achieved a perfect score with 0% of hair tangled, a somewhat rare feat for robot vacuums. The side brush is also newly redesigned to resist hair tangles.
In dried-on stain mopping tests, the X50 Ultra scored 80, consistent with other Dreamy flagships. Its water score was above average, showing good flow control without excessive streaking. It also boasts automatic mop pad lifting (over 10mm) to prevent carpets from getting wet and an automatically extending mop pad for improved edge coverage.
The X50 Ultra's charging dock is highly advanced, providing hot water washing and hot air drying for the mop pads, and automatically refilling the onboard water tank. It features a new ACE dry board self-cleaning system with a sprayer and filtration to prevent clogging, which is an upgrade from previous models.
The X50 Ultra can cross thresholds up to 36mm, a first for tested robots, using retractable legs. Additionally, its lidar sensor retracts to 89mm, enabling it to clean under low-lying furniture that other robots might miss.
In bench tests, the X50 Ultra showed average suction and airflow, along with a lackluster performance in crevice pickup. The reviewer theorizes this might be due to the dual brush design creating a wider housing opening, but emphasizes these weaknesses did not impact its excellent performance on hard floors, carpets, or deep cleaning.
85/100 source quality
