The vacuum cleaner is a very practical tool when it comes to cleaning. It was in 1901 that Hubert Cecil Booth, a British engineer, developed the first motorized machine capable of vacuuming dust. The invention was quick to revolutionize the daily lives of many households.

Today, vacuum cleaners on the market compete in efficiency and technical prowess. Cordless, bagless, economical and powerful… Clearing the floor has never been easier!

But if you use this device almost every day, there is a hidden function that many are unaware of the usefulness.

You have surely already noticed it: most vacuum cleaners have a hole on their hose, which can be blocked or uncovered thanks to a sliding hatch on the handle.

This is not a fantasy or a construction defect: this cavity has a very specific function.

When you open the door, first of all, the suction power of your device will tend to decrease. This can be useful when you clean, for example, the folds of your sofa, so that the motor avoids racing, confined in a small space, as aufeminin indicates. But that’s not all. This hole also has an essential security function.

“The manufacturers of the device have designed this hole in the event that the vacuum cleaner is clogged and thanks to it, the motor does not overheat”, Health explains to us.

Indeed, if the hose of your vacuum cleaner is blocked, you must clear the sliding hatch: the hole will thus release the pressure, without you having to turn off your vacuum cleaner beforehand, specifies aufeminin. You can then calmly unclog your tube, and avoid overheating.

Like the rest of your device, this cavity must therefore be maintained regularly to maintain these essential functions.
