Ciatronic BS 1307 floor nozzle rotates badly - how to fix it

If your vacuum cleaner Ciatronic BS 1307a become less efficient and slow in rotating a floor nozzle, probably you should to disassemble brush roller. There you should to clean around the motor, most likely there solid bunch of hair, the tip is to cut them, for example with scissors. I had spent 30 minutes to cut hair, that's why there was such problem with vacuum cleaner performance. After that seems like it becomes work better. I have been using this household appliance for 1 year.
