I've had my Kirby since 1975 and it's like an axe. (An ax will last forever if you keep changing handles and heads.) This powerful household workhorse has stood the test of time and I was delighted to find these excellent quality parts to replace one that finally broke after 45 years of service is. When I have two of these, I finally can't bend over when using the hard floor tool. Hooray! It's time.
