Only worth it if you have very low beds or sofas that other robots cannot reach, since the 3.23 in body has no LiDAR turret. Tech Advisor found it fine for upkeep but weaker on carpet, and it costs more than newer slim Roborocks with stronger suction. Most buyers should look at the Qrevo Edge 2 or CurvX first.

What reviewers found
Dreame X50 Ultra
- Vacuum Wars (3.60 Vacuum Wars stars): Removed 83% of embedded sand and 98% of pet hair with 0% hair wrap and avoided 20 of 24 obstacles. Dried stain score was 80 against a 94 average. Estimated coverage was about 1,130 sq ft per charge. Source
Roborock Qrevo Slim
- Tech Advisor: Mostly good on vinyl but missed oats and flour, and left flour and oats on mid pile carpet even after a second max run. It bumped a low hearth and swallowed a large feather, but docked reliably and hair did not wrap the brushes. Source
- TechRadar: Measured noise from about 60 dB on Quiet to 70 dB on Max+, and 44 to 58 dB when mopping. Turbo picked up all the flour and nearly all the oats, while Quiet missed many oats. Hot sauce came off after two passes. It handled thick rugs and raised thresholds but missed edges in zone mode and the area in front of the dock. Source
- Vacuum Wars (3.21 Vacuum Wars stars): Picked up 80% of 2.5 inch pet hair on carpet against a 78% LiDAR robot average and scored 76% on carpet deep cleaning, the best among its peers. Scored 110 on the dried stain test and covered about 1,244 sq ft per charge. It mapped the test home in about 5 min. Raw suction and airflow readings were below average. Source
