Adjusting the brushroll height. The Kirby brushroll is designed to adjust its height. You start it out on a low setting and as it gets worn from use instead of buying a new one you adjust it down so the brushes are closer to your carpet for years of use. Now most people have medium to high pile carpet that they are using. So when we clean them we adjust the brushroll accordingly. What happens though if you are using a low pile carpet? Then the brushroll would not be touching the carpet and your cleaning is not as good as it could be. So this is how we adjust the brushroll. First of all you take the powerhead off and put the arrows on green and then you remove the brushroll. Now on the end caps of the brushroll you will see notches and on some models different colors. Notch one for example would mean it is at its lowest setting ( for a new brushroll and high pile carpet). Then to move the brushroll closer to the carpet you would put it on 2 or 3 notches. This will make the brushes come in more contact with your carpet. Very important is to make sure that both sides are on the same notch setting. Otherwise your brushroll will be angled. Once you are done with all of that then put everything back and put your powerhead back on your vacuum.

That's really all the information that you need. You now understand how the system works, how to take the head on and off, how to adjust the brushroll and make sure that the brushroll is spinning for best results when vacuuming. Remember to check to see if the brushroll is spinning just turn the vacuum over while running to visually inspect the brushroll turning. Never stick your fingers in the brushroll to test the brushroll. I hope this has been a help and you have many years of happy use with your Kirby vacuum cleaner.
