Sometimes it's necessary to take apart a vacuum roller brush. You may need to take one apart to remove hair build-up, or to find a small item you've inadvertently vacuumed up. Occasionally you may need to disassemble a vacuum roller brush to fix it. These steps will show you how to take apart a vacuum roller brush.
Step 1 - Prepare the Vacuum Cleaner
Turn the switch to OFF on your vacuum cleaner and unplug it from the outlet. Leave the cord loose since wrapping it around the vacuum can occasionally get in the way of taking apart the roller brush. If you know for sure the cord won't get in the way, feel free to wrap it around the unit. The benefit to doing this is you reduce the chance of tripping over it or damaging the plug by accidentally stepping on it.
Lock the brush unit in place if you're working on an upright so it doesn't move as you work on the unit. (Usually, you'll be able to unlock and lock the brush section to clean under furniture.) Lay the vacuum on the floor with the flat back of the unit on the floor surface. If taking apart a vacuum roller brush on a canister vacuum, simply turn the hose over so that the brush of the head is facing up.
Step 2 - Access the Brush
Remove the top and bottom hood covering the brush of your vacuum cleaner by locating the screws and removing them with the appropriate screwdriver. These screws tend to be small and may not be able to be reused once removed due to wear or rust. Make sure you have extra screws before beginning to disassemble it. If the screws are still reusable, set them aside for when you're ready to put the unit together again. Carefully remove the hood after removing the screws. Set the hood aside so it doesn't fall and crack.
Step 3 - Look for the Belt
Look for a firm but flexible rubber-like strap that looks like a wristband. This is the vacuum cleaner belt and most vacuums have one. Sometimes the belt is connected to the brush. Carefully remove the belt to access the brush. Remember the position of it. If the belt is cracked or damaged, replace it after you've taken apart the brush and are ready to reassemble the vacuum.
Step 4 - Remove the Brush
Unsnap the brush from its brackets. Sometimes the brush will be held in place with screws. Carefully remove those screws with the appropriate screwdriver and set the screws aside. Be careful not to misplace them because these screws will not be easy to replace and will likely need to be ordered from the manufacturer if they're lost. Pull off any hair or other debris wrapped around the roller brush. Check the bristles for wear. Put the vacuum roller brush together again if the brush isn't damaged. If the bristles are too worn, contact the manufacturer or a specialty vacuum store for a replacement brush.
