An Overview On Cordless Vacuums

Cleaning the house can be a real drag, especially because you’ve likely got much better things to do with your free time. But gone are the frustrating days of tripping over your vacuum cord or trying to maneuver the vacuum in one hand while keeping ahold of the cord in another. Thanks to a little ingenuity, you can now buy a cordless vacuum, which means you never have to worry about the cord getting tangled or sucked into the vacuum again (nor do you have to worry about your new puppy pretending the vacuum cord is a chew toy!).

Cordless vacuums also make it so that you never have to stop cleaning to unplug the cord, then replug it into a closer wall outlet, which can be super frustrating if you’re short on time and just need to get the job done in a flash. Most cordless vacuum models attach to a docking station for charging. Then, when you’re ready to clean your floors, you simply remove the vacuum from the docking station and start vacuuming. The Shark Ionflex Duoclean, for example, has a removable and rechargeable lithium-ion battery that lasts about 30 minutes before you’ll need to recharge it again, which many people say is enough time to vacuum several rooms in your home, depending on their size.

If you’ve never seen a cordless vacuum up close, you’ll notice that they look a bit different than a standard vacuum. Many of these vacuums, like the Dyson V8 model, for example, are long and slender with a dirt bin and a motorhead on top. Others, like the Shark Navigator Freestyle, look very similar to a traditional vacuum cleaner with a cord. Some cordless vacuums can also easily become handheld vacuums by simply removing the motorhead from the vacuum stick, which makes for a quick and painless transition. Some cordless vacuums, like the Shark Ionflex Duoclean, have a rotating or swivel head that makes it easy to clean tough corners or get into tight spots, such as under the couch or the bed.

Cordless vacuums tend to be lighter and smaller than other vacuums, which makes them super useful if you’re short on time and just need to zip around to clean before guests arrive. They’re also helpful if you can’t lift heavy objects or your home has lots of stairs — no more lugging a heavy vacuum around.  Cordless vacuums also tend to take up less space than other vacuums, so they’re perfect for smaller spaces such as apartments and condos.

DYWM Fun Fact

You can thank NASA for your cordless vacuum — yes, NASA. The reason we have cordless vacuums in our homes today is because NASA needed a company to design a special drill so that Apollo astronauts could extract core samples from the moon in the early 1960s. Since they were on the moon with no power source, the drill had to be cordless, lightweight and small. NASA asked The Black & Decker Manufacturing Company to design something and the company pulled through by developing a battery-powered technology, which was the precursor to today’s modern cordless power tools and vacuums. Thanks NASA!

The Cordless Vacuum Buying Guide

  • One of the key factors you’ll want to consider when purchasing a cordless vacuum is battery life, since this will determine how long you can run your cordless vacuum before it needs to be charged. Cordless vacuums can run, on average, between 15 and 45 minutes between charges, depending on the type of vacuum and the setting you select. You won’t be able to use your cordless vacuum for very long if you select the highest-power mode, so keep that in mind when you start cleaning. The Dyson V8, for example, can run for eight to 40 minutes, depending on which mode you’re using to clean your house.
  • Cordless vacuums typically use one of three types of batteries: lithium-ion, nickel-metal hydride and nickel-cadmium. Each battery type has its own pros and cons, and they all have varying levels of power, shelf life, replacement cost and charge capacity. Lithium-ion batteries, for instance, tend to be more expensive than nickel-cadmium batteries and you may have to be careful not to overcharge them. Generally speaking, nickel-cadmium batteries tend to need to be replaced more often than the other types, while nickel-metal hydride batteries are more expensive but they hold a lot of power from each charge. Typically, your battery will not be covered under a limited warranty if it fails because of normal wear and tear. Over time, you can likely expect to have to replace the battery for your cordless vacuum.
  • You’ll also want to consider the weight of the vacuum. If being lightweight is important to you, you’ll want to take a look at the product specs for each cordless vacuum. They typically range from 2 to 7 pounds. The Hoover Linx, for example, weighs 7.3 pounds, while the Shark Navigator Freestyle weighs 7.5 pounds. Even so, this may be a lot lighter than the regular vacuum you’re used to.
  • Most cordless vacuums come with washable filters, which means you’ll need to keep an eye on how dirty this filter becomes and clean it periodically to keep the vacuum running properly.
  • Another factor when purchasing a cordless vacuum is whether it comes with a warranty, as well as what types of situations are covered by the warranty. The Shark Navigator Freestyle comes with a one-year limited warranty that covers defects in material and workmanship during normal household use. The Dyson V8 comes with a two-year limited warranty for defects in material and workmanship for normal household use. These types of limited warranties typically do not cover damage caused by normal wear and tear, misuse or aging batteries.
  • Cordless vacuums come with an array of accessories and attachments. Some of the most common accessories are crevice cleaners, mini brushes and extension heads. The Shark Ionflex Duoclean, for examples, comes with a duster crevice tool, a dusting brush, a wide upholstery tool, an anti-allergen dust brush, a battery and a charger.
