If your vacuum cleaner isn't spinning the brush roll but still makes noise when turned on, there could be a few possible reasons for this issue. Here are some troubleshooting steps you can follow to try and fix the problem:
Check for obstructions: Turn off and unplug the vacuum cleaner. Inspect the brush roll and surrounding area for any debris, hair, or other objects that may be blocking its movement. Clear any obstructions you find.
Inspect the brush roll: Remove the brush roll (refer to your vacuum cleaner's manual for instructions) and examine it for any damage or excessive wear. If the brush bristles are worn down or tangled with hair, consider cleaning or replacing the brush roll.
Examine the drive belt: The drive belt connects the motor to the brush roll, enabling it to spin. Over time, belts can stretch, break, or slip off the track. Carefully check the belt for signs of damage or wear. If it appears loose or worn, you may need to replace it.
Check the motor: The noise you hear could be the motor running, but if the brush roll isn't spinning, it might indicate an issue with the motor's connection to the brush roll. You may need to open up the vacuum cleaner (if you're comfortable doing so) to check for loose or broken connections between the motor and the brush roll.
Inspect the brush roll's bearings: Some vacuum cleaners have bearings at the ends of the brush roll that allow it to rotate smoothly. If these bearings are clogged with dirt or hair, they might prevent the brush roll from spinning. Clean or replace the bearings if necessary.
Check the height adjustment setting: Some vacuum cleaners have a height adjustment feature that allows you to change the brush roll's height according to the type of flooring you're cleaning. If the height is set too low on a high-pile carpet or if the setting is incorrect for your flooring type, the brush roll might not spin correctly.
Look for broken parts: Inspect the vacuum cleaner for any broken or damaged parts that might be hindering the brush roll's movement. If you find any broken components, they will need to be repaired or replaced.
If you're unsure about performing any of these troubleshooting steps or if the problem persists after attempting to fix it, it's best to take your vacuum cleaner to a qualified technician or an authorized service center for further diagnosis and repair. They have the expertise and tools to identify and resolve more complex issues with your vacuum cleaner.
