I suspect that the matter is in the quality of the plastic and the "savings" of the manufacturer on this very plastic (the old Samsung, bought in 2022, there is no such problem. It's a pity that the pipes are not interchangeable, the diameter is different, but I'm already thinking about an adapter). Repair: I bought a two-component glue and stupidly closed up this misunderstanding from the manufacturer, then trimmed it with a knife. Everything is holding up, see photos. Time passed and my "stucco molding" fell off along with what I sculpted, with what was on the pipe . It's a shame, a good vacuum cleaner, but because of the greed of the manufacturers (or because of the stupidity of the designers) such a jamb . Well, why, everything is done through a "bottleneck" .
