I just had the exact same situation a couple of months ago. But my wife and I were not very upset because the vacuum cleaner was already old and we would soon throw it out. Since you also have a dog, I advise you to take a sufficiently powerful vacuum cleaner that can suck up all the dog's fur. Our family friend advised us to watch the Shark Ionflex Review and my wife and I realized that this was what we needed. Now the dog's fur does not bother us anymore because this model of a vacuum cleaner can clean even in the most inaccessible places in the house. I wish you good luck I hope I was able to help you and you will be satisfied.
