Cutting the cord and having the freedom to move through all levels of the house is one of the main reasons to buy one of the best cordless vacuums. We’re big fans of these types of vacuums, not only because we don’t like being held back, but also because we love how versatile, lightweight, and easy to use they are.
Cordless vacuums and Black Friday
Just for your information, if you are looking to buy a cordless vacuum cleaner, now might be the ideal time to start shopping. The Black Friday deals are just a few weeks away, and we expect to see some fabulous Black Friday deals rolling out soon. You might even see some Black Friday Dyson vacuum deals if you’re willing to splurge. For more affordable options, we’re also anticipating plenty of Black Friday Shark vacuum deals. Both brands have highly sought-after cordless vacuums that are worth keeping an eye on.
While cordless vacuums are great, one of the main things we’ve tested – and one of the first things we’ve looked at in every vacuum’s spec – is the runtime. Runtime is how long the battery will last before needing another charge. There’s nothing more irritating than a vacuum cleaner stopping dead while you’re in the middle of vacuuming the rugs upstairs, or when you’re almost done banishing crumbs to the dustbin in the car that’s parked down the road. These are trivial problems compared to some, of course, but when a vacuum that isn’t plugged into the mains dies on you during a cleanup mission, it’s a problem all the same.
There are some vacuum cleaner brands that sell separate batteries, which means you can buy an additional battery pack and get twice the power available. Some even include a spare battery as standard, effectively turning a 60-minute runtime into 120 minutes.
This sounds like a dream: an answer to a vacuum cleaning problem. But what is the reality of this? Well let me share…
Ah, the cordless vacuum. They come in vastly different shapes, sizes, and colors, with some models much more technical than others that are simpler, but just as effective. Those with the most premium price tag usually come with more features, which makes sense, and some have more battery and/or more battery options.
Take the Dyson V15 Detect, for example. There’s a lot going on with it, as we discovered when testing it for our Dyson V15 Detect review. For example, it has a high torque cleaning head, which when used in Auto mode will adjust the power to suit the type of floor you are cleaning; intelligent. It also features a Laser Slim Fluffy cleaning head, which has a soft brush bar to ensure hard floors are not damaged. In addition, it has a class 1 laser diode (so it is safe for humans and pets) mounted at a 1.5 degree angle and 7.2 mm from the ground, which projects a beam of green light in front of the head. cleaning tool to highlight microscopic dust particles. There’s also a color LCD screen, which shows the level of dust collected and remaining runtime.
In short, it’s a feature-packed device – and therefore one that needs a lot of power. Dyson claims the battery will last up to 60 minutes on the lowest power setting, Eco, and that’s what we found in our testing: it goes on for 59 minutes before needing to be recharged.
While 60 minutes may seem like a lot, some people may need more. And while the battery can be swapped out to double its runtime, it will cost more – making an already very expensive vacuum even more expensive.
Of course, if you end up getting a second battery, you’ll need to make sure you keep it charged at all times, so you can quickly change it if your vacuum dies mid-clean. You will also need to figure out how to take out the dead battery and replace it with the new battery. This may or may not be a big deal for you, but it’s always worth doing some preparation.
I also recently tested the Miele Triflex HX2 Pro cordless vacuum. This one has a slightly lower spec than the Dyson above, but it’s a really robust, versatile and powerful model that deftly handles any small debris in its path.
Unlike the Dyson, this one comes with two batteries as standard. Miele claims that each offers a runtime of 60 minutes, so two batteries will obviously give you 120 minutes. That sounds mega, and if you don’t compare the Miele HX2 range beforehand, you’ll probably feel like you’re getting a good deal.
However, it’s not that simple. In a nutshell, you’re paying an extra £200 for that extra battery when compared to the Miele HX2 Cat&Dog, which only has one but is cheaper at that price. You might find it a reasonable compromise because you won’t have to find and buy an additional battery.
I found that on the HX2 Pro I didn’t get anywhere close to 60 minutes running time when switching between the ‘Eco’ and ‘Max’ settings; I was lucky to get 35 minutes in this case. You’ll be closer to hitting max runtime on the ‘Min’ setting, but that won’t help much if you have some really heavy cleaning to do.
That’s where the second battery can come in handy, then, but unfortunately when I went to change the new one, I found it wasn’t charged; not ideal because it meant I had to reschedule the vacuum cleaning task until this was done.
And don’t think it’s a quick process either. Miele HX2 models normally need 4 hours to accelerate; Dyson V15 Detect takes 5 hours. If you find the second battery empty midway through cleaning, like I did, you’re in for a long wait.
Of course, this is just user error on my part, but it’s something you should be aware of if you want to see the benefit of the dual battery vacuum cleaner approach. It’s a great option in theory, but you’ll need to plan ahead – and have deep pockets – for it to be worth it.
