At a high level, the Ecovacs Deebot X11 OmniCyclone and the Yeedi S20 Infinity share the same core feature set: both carry a HEPA and allergy filter, integrate with Google Assistant and Alexa, and come with a 1-year warranty. Their physical footprints are nearly identical — differing by just 2 mm across width, height, and thickness — and their operational noise levels are effectively a wash at 65.7 dB vs. 65 dB, a difference imperceptible to the human ear in a real home environment.
Where the two diverge meaningfully is in weight, docking station size, and dust bin autonomy. The Yeedi S20 Infinity is notably lighter at 4100 g versus the X11's 5000 g — a 900 g difference that matters when manually moving the robot between floors or lifting it for maintenance. On the other hand, the X11's docking station is substantially larger (87113 cm³ vs. 59400 cm³), which translates to a significantly bigger footprint in your living space. The Yeedi's more compact dock is a genuine advantage for users with limited floor space near a wall outlet.
The most impactful differentiator in this group is the estimated empty time: the X11 claims 150 days between dust bag changes compared to the Yeedi's 90 days — a 67% advantage. For users who prioritize a ″set it and forget it″ experience, this is a significant practical benefit. Overall, the X11 edges ahead on long-term maintenance convenience, while the Yeedi counters with a lighter body and a smaller dock — making it the better fit for space-conscious households.
