Question about Roborock S6

No, the Roborock S6 needs a WLAN and an internet connection. The vacuum cleaner is controlled entirely via an app. This then talks to Roborock's server, which then talks to the S6. When your household goes offline, the Roborock returns to the charging station and charges, but does not continue cleaning.

Or to put it another way, does Digitec also offer robot hoovers that work without the internet?
