Question about Dreame Matrix10 Ultra

Good day, I have found two different articles in your catalogue: Dreame Matrix10 Ultra Robot Vacuum Cleaner (item no. 61347404) - price CHF 1'530.- Dreame Matrix10 Ultra Robot Vacuum Cleaner (Art.-No. 61347411) - Price CHF 1'299.- Could you please explain to me what exactly the difference is between these two models (e.g. functions, accessories, station)? I am particularly interested in why the "vacuum robot" version is more expensive, although according to the description it should have fewer functions than the "vacuum mopping robot" version. Thank you very much for your feedback!
