To stop the brush from rolling on a vacuum cleaner, you usually have two options:
Manual Control Switch: Many modern vacuum cleaners come with a manual control switch that allows you to turn off the brush roll. Look for a button or switch on the vacuum cleaner's head or handle that says "Brush Roll On/Off" or something similar. When you switch it off, the brush roll will stop rotating, making it easier to clean certain types of surfaces like hardwood floors or delicate carpets without causing damage.
Height Adjustment: Some vacuum cleaners have a height adjustment feature that allows you to raise or lower the vacuum cleaner's head. When you adjust the height to the highest setting, it automatically lifts the brush roll off the floor, preventing it from rolling and spinning. This is useful when you want to use the vacuum on hard floors or when you're vacuuming delicate rugs.
If your vacuum cleaner doesn't have either of these features, you can try using the vacuum on hard floors without engaging the brush roll, but be cautious as it may cause wear and tear on the brush roll over time. Additionally, if you find that your vacuum cleaner's brush roll is continuously rolling even when you don't want it to, it might be worth checking the user manual or contacting the manufacturer's customer support for assistance. Some models may have specific methods or troubleshooting tips for this issue.
