Roborock S8 MaxV vs Dreame L20 Ultra — honest comparison from an owner of both

I've owned the Roborock S8 MaxV Ultra for 8 months and just got the Dreame L20 Ultra two months ago. Both are flagship robot vacuums with similar features, but there are key differences most reviews miss. Here's my real-world comparison.

Suction: Dreame wins marginally on carpet, Roborock better on hard floors.

Navigation: Roborock is noticeably smarter with obstacle detection. The Dreame bumps into things more.

Mopping: Roborock's VibraRise 2.0 is better at deep cleaning. Dreame's mop lifts higher though.

App: Roborock's app is more polished. Dreame's has more features but feels cluttered.

Dock: Both work well but Roborock's self-cleaning is quieter.

Reliability: Roborock has been rock-solid. Dreame needed a firmware update to fix a mapping bug.

Overall, I'd give the edge to Roborock for most people, but the Dreame is better value at its lower price point.
