Both the Ecovacs Deebot T80 Omni and the Deebot X8 Pro Omni share a solid foundation of filtration quality, each equipped with a HEPA and allergy filter, making either a reasonable choice for households sensitive to dust and allergens. They also share identical robot unit volumes and nearly the same footprint, so neither will feel meaningfully more or less intrusive on the floor itself.
The more telling differences emerge in noise output, smart home compatibility, and physical weight. The T80 Omni operates at 63.4 dB versus the X8 Pro Omni's 65 dB — a gap that, while small in absolute terms, is perceptible to the human ear in a quiet room, giving the T80 Omni a slight acoustic edge for daytime or light-sleep-hour cleaning. On smart home integration, the T80 Omni supports both Google Assistant and Alexa, while the X8 Pro Omni is limited to Alexa only — a meaningful drawback if your home ecosystem is Google-based. Flipping the advantage, the X8 Pro Omni's robot unit is notably lighter at 4100 g compared to the T80 Omni's 4950 g, which matters when manually carrying or repositioning the robot. The X8 Pro Omni also has a larger docking station footprint (88984 cm³ vs 77571 cm³), so it demands more dedicated floor space.
Overall, the T80 Omni holds the edge in this general spec group: it runs quieter, supports a broader range of voice assistants, and has a more compact dock — with the X8 Pro Omni's only compensating advantage being its lighter robot body.
