It would be nice if the EU or someone introduced an energy star type system for reliability and repairability so that consumers could have some kind of idea what the quality is likely to be.
All parts still available and when I bought new hose few years ago from service I asked if they still are willing to fix it if it went broke answer was.

Third party dust bags are available and very cheap.
