Great save!
Yes, it is absolutely shameful the way some people abuse those machines but a testament to the quality of their construction that they take the abuse and just keep going. Kirbys are just plain hard to kill!
I can kind of see the scenario of this one: They'd had the thing for so long they'd kind of forgotten exactly when they bought it and, well, it was getting kind of old and the bag was getting pretty full so it had to be worn out, right? And besides, it's getting kind of nasty so let's just put it out by the curb and grab a new bagless plasticrap vac the next time we're at Wally World, you know, one of those new ones that has the hose built in. They're so much lighter weight and it'll be so much better... Nevermind the fact that plasticrap vacs are a false economy.
Idiots! They don't deserve a Kirby but you do. Thanks for saving that one!
