Let me tell you…

Not having power cords in the way while cleaning definitely helps clean faster and prevent accidents!

I was recently gifted with a cordless vacuum cleaner and it’s been great! But can you use a cordless vacuum when it’s charging?

Can You Use A Cordless Vacuum While Charging?

No, you cannot use a cordless vacuum while it’s charging. Most cordless vacuums come with very short power cables. Furthermore, using the vacuum while charging will damage the battery’s power storage function. It is recommended you only use the vacuum after full charge to extend battery life. If you do need to use your cordless vacuum for longer, you may purchase a spare lithium battery that you can interchange with the main one.

Cordless vacuums come with very powerful motors, which require a substantial amount of power to function correctly.

The charger that comes with these types of vacuums are simply not powerful enough to supply current for continuous, high-suction use.

What Are The Disadvantages Of Using A Cordless Vacuum?

In my opinion, cordless vacuums should only be used for quick, every day cleaning.

In fact, I own both a cordless vacuum and a corded one.

I use the cordless vacuum to vacuum around the house to keep the floor clean on a daily basis.

However, if I need to clean carpets or do a spring clean, I use my corded vacuum.


For many reasons, including:

1. Cordless vacuums are less powerful than their corded counterparts

2. The battery does not last long enough to deep clean the entire house

3. The battery will drain even quicker if you use your cordless vacuum at full suction power

4. Swapping batteries around for the sake of making the vacuum last longer throughout the day can be a pain

How To Make Your Cordless Vacuum Battery Last Longer

As I mentioned earlier, using a cordless vacuum while it’s charging can damage the battery.

But what else should you avoid/do to make the battery last longer?

1. Only use the vacuum once the battery has reached full charge

2. If possible, try to use your cordless vacuum in short bursts rather than extended periods of time. This will help preserve the battery life.

3. Make sure to clean the vacuum’s filter regularly. A clogged filter can cause the vacuum to work harder and use more battery power.

4. Store your cordless vacuum in a cool, dry place when not in use. Extreme temperatures can damage the battery and reduce its lifespan.

5. Avoid leaving your cordless vacuum unused for long periods of time. If you do not use your vacuum regularly, the battery will become discharged and may eventually become damaged.

6. When not in use, disconnect the battery from the charger to prevent overcharging.

7. Avoid using generic or aftermarket batteries, as these may not be compatible with your cordless vacuum and could damage it.

Should You Buy a Spare Battery For Your Cordless Vacuum?

Having a spare battery for your cordless vacuum can be extremely convenient.

If your primary battery dies while you’re in the middle of cleaning, you can simply swap it out for the spare and continue on with your chores. This can save you a lot of time and frustration.

However, if you’re on a tight budget, you may not be able to justify the cost of an extra battery.

The same applies if you only use your cordless vacuum occasionally!

Ultimately, whether or not you should buy a spare battery for your cordless vacuum depends on your individual needs and circumstances.

If you think having a backup would be useful for you, then it’s probably worth the investment. Otherwise, you may want to skip it and save yourself some money.

Again, I personally recommend you only use your cordless vacuum for light cleaning and purchase a corded vacuum for deep cleaning.

The process will slightly vary depending on the vacuum you have, but the video will be helpful regardless:


It is never a good idea to use a cordless vacuum while it is charging. Doing so can damage the battery and shorten the lifespan of the vacuum.

If you need to vacuum for extended periods of time, consider buying a spare battery or a corded vacuum cleaner you can use for deep and spring cleaning.
