Based on a conversation with another very lovely NDMNer... 
So I have finally (albeit following through on a particularly nasty meltdown) managed to kill our much-hated Dyson.
Can I ask for thoughts on good vacuums for pet (cat) owners? We live in quite a wee tenement flat with lots of hard floor / carpet / rug crossover, so I don't think a robovac would be worth it, but I have been looking at Shark uprights?
I hear they make a nice noise, too: everybody wins.
