Leaving a vacuum cleaner plugged in, even if it's turned off, is generally safe and shouldn't cause any immediate issues. However, it's a good practice to unplug electrical appliances when they're not in use for an extended period. Here are a few reasons why:
Energy consumption: When an appliance is plugged in, it can still draw a small amount of standby power, sometimes referred to as "phantom" or "vampire" power. Although the power consumption is minimal, it can add up over time and contribute to unnecessary energy waste.
Safety concerns: While the risk is generally low, there's a small chance of electrical issues such as power surges or short circuits occurring when an appliance is left plugged in. These incidents are rare, but by unplugging the vacuum, you eliminate any potential electrical hazards.
Convenience and longevity: Unplugging the vacuum after use helps avoid accidentally turning it on or tripping over the cord. Additionally, unplugging appliances when not in use can contribute to their longevity by reducing wear and tear on internal components.
It's a good habit to get into the practice of unplugging electrical appliances when they're not in use, especially if they won't be used for an extended period or when you're leaving your home for an extended time. By doing so, you can save energy, reduce potential hazards, and extend the lifespan of your appliances.
