While my Kirby wasn't sucking, it made a loud squeak/whoosh that got incredibly annoying. I've noticed that the fan is sometimes clogged with hair and the blades are badly chipped and dented. I did a quick web search and from the information I gathered realized that the fan blades needed replacing. The product arrived on time, all parts were in stock. NOW the replacement process would have been a lot easier if a more informative video explained exactly where to put the wrench on the motor to keep the spindle from moving until I tapped it. mine was too tight. When it was sorted everything was fine. Replaced fan and WOW mega suction and no howling noise. Great buying experience. I'm sure I know who to contact if additional details are needed.
