The vacuum cleaner doesn't need a lot of attention, but a little simple maintenance will keep it running and cleaning the best of it capability.
1. Empty the dust container after every cleaning. After every 2-3 cleaning you can do complete clean the container by wash, rinse and let it air dry before you attach it back to the vacuum.
2. Clean the brush row, aka beater bar. Especially if you have long hair, more than likely hair will wrap tight around the row. If there are a lot of hair, the brush will not be able to catch the dirt that on the carpet (check the bottom of your vacuum and you will see what exactly, I'm talking about.)
It's a lot easier if unattached the row and cut out all the hair. Check you manual book, most of the vacuum you could just pop out the cover and remove the row. When you put the row back, make sure you put the belt the right way. If you put the belt wrong it will burnt and can leave the melted plastic on your carpet.
3. Change the filter every so often. Remember keep it white or light gray. Clean air filters are important for air movement on bagless vacuum; even a modestly dirty filter can cut a vacuum cleaner’s suction in half.
