Dyson’s secret tips to increase battery life & suction power on your cordless vacuum

Cleaning the house can suck the life out of your vacuum cleaner’s battery (literally), eventually leading to a shorter runtime and leaving you with weaker suction power. But, did you know that little things like storage temperature and the type of surface you’re tackling with your machine could be at play?

We asked Dyson’s Quality Manager, James Shale, to explain how a vacuum battery works and got his top tips on making the most out of your cordless vac.

What can affect the battery life of a vacuum cleaner?

Can’t figure out why your vacuum cleaner isn’t working? A handful of vacuum owners (11%) we surveyed in our latest research said they’re often disappointed with their vacuum’s performance, with a similar number of consumers also wishing they had spent more money on a better vacuum cleaner (13%).

According to Mr Shale, there are multiple factors that can affect the battery life and overall performance of your cordless vacuum. Some include:

  • Cleaning mode used
  • Surface type
  • Temperature at which the vacuum is stored
  • Regularly charging the vacuum
  • Maintenance
  • Age of vacuum

How can you increase the battery life of a Dyson vacuum?

Increase battery life of a Dyson vacuum

There are several ways you can extend the lifespan of a battery on a Dyson vacuum, plus the runtime of a single battery charge. “Owners can help preserve the runtime and overall life of their machine’s battery by using the power mode best suited to the cleaning task, and only using ‘boost’ mode for intensive cleaning,” Mr Shale says.

Here are some steps to take to extend the battery life on Dyson vacuums:

  1. Make sure your vacuum has a full charge
  2. Use the right cleaning mode
  3. Consider the type of surface(s) you need to clean when choosing which stick vac to buy
  4. Store your vacuum at room temperature
  5. Regularly clean your vacuum filter

Make sure your vacuum has a full charge

Dyson’s Quality Manager says that no two vacuum batteries operate in the same way, but that fully charging your cordless vacuum cleaner before using it for the first time, and after every clean, can help the battery last longer.

Fully charging the battery before using your vacuum helps to kick-start what’s known as the ‘calibration process,’ which helps the appliance ‘learn’ how that individual battery behaves. Most vacuum batteries are self-calibrating these days, but it doesn’t hurt to keep up good practice. Most models can be left on charge throughout the day and when the battery is fully charged, the machine won’t use any more electricity.

Use the right cleaning mode

Adjusting the cleaning mode on your cordless appliance can add a few valuable minutes to your vacuuming time. If you’re just cleaning up cereal off the kitchen floor, you should only need to use a low power mode. You should only really boost your vacuum’s power when you need it, such as for getting pet hair out of the carpet, for example.

Consider the types of surfaces you need to clean

Not all vacuum cleaners are created equal. Some stick vacuums are designed to be suitable for carpets only, but others are made to clean a variety of surfaces like tiles, hardwood floors and furniture. “Runtime can be affected by the cleaning mode used and the different power draw on varied surfaces – long pile carpets will draw more power than short pile carpet for example,” Dyson’s Quality Manager says.

That’s why it’s important to consider the types of surfaces in your home when buying any vacuum cleaner. Barrel vacuums are still the best for cleaning a variety of surfaces like carpets, tiles and upholstery. But, if you’ve got mostly carpets throughout, upright vacuums also have the power capacity to lift out trodden-in dirt and stubborn pet hair.

Store your vacuum at room temperature

Rechargeable lithium batteries and extreme temperatures don’t mix, which is why it’s important to store your vacuum cleaner at room temperature.

“Any lithium-ion battery can be affected by extreme temperatures, so we recommend storing your machine at room temperature, away from boilers, heating appliances or even areas where temperatures get very low. This will ensure the longevity of your battery life,” Mr Shale says.

Regularly clean your vacuum filter

Dyson’s Quality Manager suggests that proper filter maintenance is quite often neglected by the average user. He says that filters should be unclogged, washed and dried regularly to keep them optimal and maximise your vacuum’s suction power. If you notice your machine still isn’t ‘sucking’ as much as it used to after filters have been cleaned, it may be time to upgrade.

How long do batteries last in cordless vacuums?

Not all vacuum batteries are created equal. To see which cordless vacuums offer the longest cleaning time, we have compared the expected average runtime and recharge time of a single battery from several major brands. Keep in mind runtimes will vary depending on specific models.

Brand Maximum runtime Recharge time
Dyson 30-60 minutes 3.5-5 hours
Electrolux 48-60 minutes 4 hours
Hoover 19-45 minutes 4-8 hours
Kmart 30-40 minutes 5 hours
Vax 20-45 minutes 3-4 hours

When should you replace your cordless vacuum cleaner?

According to Mr Shale, there are two main signs that suggest a vacuum needs maintenance, or should be replaced altogether.

  1. Reduced suction power
  2. Decreased runtime

The age of your appliance can also give you a good idea of whether it’s time to simply replace the battery or shop for another vacuum. Our latest research shows Aussies typically own their stick vacuum for about six years.

Reduced suction power

If you’ve noticed the suction power on your cordless vacuum has decreased, here are two things to check or do before sending it off to the scrappers:

  1. Look for blockages within the machine
  2. Wash the vacuum’s filters

Decreased runtime

Has your vacuum’s runtime shortened comparatively to when you first bought it? According to Mr Shale, lithium-ion batteries will degrade over time, so problems like decreased runtime might mean your battery needs to be replaced. The age of your vacuum can also give a good indication of whether you’re due for a replacement or an upgrade.

4 things to consider when buying a cordless vacuum cleaner

What to look for when buying a cordless vacuum cleaner

When shopping for a new cordless vacuum or comparing models from different brands, Mr Shale suggests the most important features to consider include:

  1. A fully-sealed filtration system that can capture up to 99.9% of fine particles
  2. A powerful motor to support suction power and capacity
  3. Enough runtime to clean your living space
  4. Bin capacity
