My new Seauto Crab

I like this new Seauto Crab that I bought 2 weeks ago and it scans all area. However, the dirt is collected outside the basket. As you see in this video, the collected sands are not in the basket, so once the pool pump stops, the next day most dirt is still in the pool. I don't know if this vacuum is defect or it is the way how this vacuum behaves. I am going to contact the Temu where I bought and ask whether I should return for good or whether there is a way to correct this behavior.
