Samsung patents vacuum cleaner with built-in motor cooling system

Samsung has been granted a patent for a vacuum cleaner design that keeps the internal motor cool during use. The system uses a spinning brush to pull outside air directly through the motor, then channels that warm air out through the main suction pipe to help remove dust.

Why it mattersThis design aims to improve the durability of the vacuum's motor by preventing overheating, which is a common issue in high-power cleaning devices.
