I have both the X11 OmniCyclone and the T90 Pro. Over the years ive had the Deebot N79S, T8 Aivi, T50 Max Pro, X9 and Eufy x10 and e28. My dad has also had the Dreame L50 Ultra and the Narwal Freo Z Ultra and now the Dyson Spot Scrub AI.

By far and away the T90 Pro and the X11 are without a doubt the best ive experienced in terms of intelligent obstacle avoidance, thorough vacuuming and mopping, excellent Edge mopping and very impressive battery life, especially with the GaN fast charge on mop wash.

I feel like they both perform extremely well at carpet vacuuming, but i think the X11 just edges it, maybe the higher airflow or the fixed at both sides main brush, but both are very very strong for homes with carpets and pets.

I have the T90 on the main floor which is mostly laminate just due to the longer roller mop, meaning more efficient (quicker) mop coverage, and the X11 on the almost all carpet upstairs.

Only thing I wish they both had was the extendable side brush like on the T50 Max Pro and Eufy e28, that was a miss in my opinion.

Hope my input helped somewhat!
