Thanks all. That discussion alerted me into checking out a type of vacuum cleaner I've not used before and so I checked out the Miele cylinder ones and landed up eventually getting a Bosch cylinder one. Fingers crossed it'll do the trick (it was the lightest wired-up one I could find of any) and fingers crossed that buying a Bosch specifically means that's the last one I ever have to buy (motor guarantee of 10 years - I estimate that's about how long I'll need it). Crosses fingers re the usual reason I have for Bosch applying (ie I've just swopped a Bosch washing machine I figure must have been at least 20 years old and was still working for another Bosch one). Tries to forget my last kettle (Bosch again) only lasted 3 years 8 months - so I did buy a different make of that and hope for a reasonable lifespan from that one.
He has done it! The toolmakers son has resigned!
