There are many ways in which you can maintain your vacuum cleaners. You should change your vacuum bag at least once a month. The dust cup must be emptied when it is two-thirds full. If you have a larger home and a number of pets are around, you must change your bag more frequently. You can use the line printed on the bag as a simple reminder. If the dirt is above this line, then you know it’s time to empty the bag.

You also have to replace the belts on the vacuum when needed. These belts are made of rubber and are constantly stretch. After some time, they also wear out. A newer and tighter belt will aid in better performance of the vacuum cleaner. You can check the agitator belt for signs of wearing out. In general, it should be replaced in a period of six months. You can also check the manual for instructions on belt replacement.
