I had an older model shark navigator that I absolutely loved and used over a decade. The hose split mulitple times. The vacuum kept on running until duct tape no longer stopped the air leaks. Unfortunately, I could find a replacement part. Time for new! My new Navigator is as good as the last, even better. It is so easy to go from carpet to floor with the click of a button. So easy to remove the hose attachment for cleaning the tops of curtain rods or my dogs' bed. I didn't think Shark Navigator could get better. I am happy to say I was wrong!  Love it!
