Both models are excellent cleaning devices, too, and each uses an extendable roller mop that can apply up to 4,000Pa of pressure and reach hard-to-clean areas (including corners). The biggest differences between the two models come down to how they handle suction and airflow while vacuuming. For instance, the last-gen X8 Pro Omni offers slightly more powerful suction at 18,000Pa, compared to 16,600Pa on the X9. The X9 Pro Omni, meanwhile, leverages Ecovacs’ Boosted Large-Airflow Suction Technology, which moves more air through the vacuum, allowing dust and debris to be pulled in more easily for a deeper clean.
