In principle, the answers are correct, but all Roborock hoovers can also be used without the app, because it is sufficient to simply press the Clean button on the device. The robot hoover then starts cleaning the home and then returns to the docking station.

However, you need the app for firmware updates and also to edit the maps or to programme the hoover so that it not only cleans the flat but can also do this every day, for example.

Roborock s7 does not connect to the network. WLAN strength, password, correct device ..... all checked exactly and several times. However, the connection always fails. What could be the cause?

To Stettlermarcel and GüntherB39 - a big thank you for the complete answers. It has helped me a lot.
