We are so happy that our parents bought us a Kirby for our wedding present 36 years ago. It was an absolutely amazing wedding present. We used it for many, many, many years. When it finally gave up the ghost, what did we replace it with? That's right another Kirby vacuum cleaner. Need I say more? We are completely in love with our Kirby vacuums. If it breaks there are wonderful repair shops ready with the replacement part hubby needs to fix it. Yep, every time hubby has been able to fix them. They are machines that just keep on sucking up the trash, no matter what we throw at them. Maneuverability Okay I will admit that are big, but they have so much power to get the job done. Ease of Maintenance Biggest thing that we have to do is cut off the long hair of our three daughters from around the brush. and replace the belt every so often. Suction Performance Suction is great. Even works on old shag carpets!! Yep we still have them. Versatility Love that we are able to use it on hardwoods as well as carpets. Design Like I said they are a bit cumbersome. But we love it. Durability Lasts and lasts and lasts. We have only had two Kirby's during our 36 years of marriage.
