I would recommend that you stay with your, hopefully functioning, Luba 1. I've owned a Luba 2 for 2 months and will probably have to write it off completely --> take a look here: https://www.roboter-forum.com/threads...
I used to be delighted with my robot, but now I'm just totally frustrated

Unfortunately, the LUBA 3,000 and 5,000 models were sold out within a very short space of time, and the 1,000 model is now also sold out, and no more supplies are planned for this year as the robotic mower season is slowly coming to an end. We hope that we may still receive a small quantity of replenishments, but we can't say anything more specific at the moment.
We are working on making the complete line-up available in larger quantities for 2025.
The YUKA models are still available at the moment.

We have not yet been offered the desired model. However, we will add the item to the shop as soon as possible.
