Vaccum cleaner for 2 bed flat

Hi, Mostly carpets a 2 bed flat.

I have tried to look and get confused with choices.

Not interested in cordless one either - prefer just wiring to socket (old fashioned way and no worrying about battery/charging etc).

Need something that will last me 8-10 years! Budget wise guessing £200 will suffice? I can stretch more as long you think its worth to spend on a vaccum cleaner that meets the spec above.
