Great to work, but difficult to clean and likely to have short life due to design - since all carpets cleaned a few times How to buy this nozzle with a vacuum cleaner. This head is great in action and sucked up all the dirt and hair but to clean it I had to completely disassemble it every time after cleaning and decided to take a picture after the last cleaning - see attachment. Dust was all over the reading, it should have had better seals. The metal gear on the motor, which is connected to the plastic gear on the brush roller by a small rubber toothed belt, causes problems due to the design. There is no way to control the belt tension. I have no doubt it will fail after a few cleaning cycles.
