Key differences between Narwal Flow 2 and Narwal Freo X Ultra

A summary of selected recorded differences between these robot vacuums. Check the full specification table below for details and conditions.

Feature differences among your selected devices

Self Emptying (features): Narwal Flow 2 — Yes (2.5 L dust bag, up to 120 days maintenance free); Narwal Freo X Ultra — No (The base station has no dust collection. Narwal contrasts the Freo X Ultra with robots that empty into their station, describing a built-in system that compresses dust into the robot's own disposable bag instead).
Apple Home (integrations): Narwal Flow 2 — Yes (Matter certified in the CSA product database, plus Siri voice control); Narwal Freo X Ultra — No (Narwal names only Alexa, Google and Siri for this model, Siri running through the Narwal app rather than the Home app, and the robot carries no Matter certification that would open an Apple Home path).
Home Assistant (integrations): Narwal Flow 2 — Yes; Narwal Freo X Ultra — No (The community Narwal integration, the only one that exists, lists the Freo X Ultra as not compatible: this model talks ZeroMQ on port 6789 plus the Tuya cloud instead of the WebSocket protocol the integration drives).
Matter (integrations): Narwal Flow 2 — Yes (Listed as Flow 2 in the CSA Matter certified product database); Narwal Freo X Ultra — No (A search of the CSA certified product database returns only the Narwal Flow and Flow 2, not this model).
