Thank you for your question. The robot also works without GPS for a short time, but there may be deviations when mowing.
If the reception fails for a longer period of time, the robot stops and does not continue. As we do not know how big the tree is and how strong the signal is, it is difficult to make a final judgement.
Best regards,

The robot lawnmower also works without a boundary wire and uses precise positioning technology that does not rely on GPS alone. It creates a virtual map of the garden and recognises obstacles such as trees using AI vision, allowing it to avoid them even if GPS reception is impaired by the tree. This eliminates the need for a wired robot lawnmower, even if there is a large tree in the centre of the plot.
