Bagless vacuum cleaners

Bagless vacuum cleaners
It's been more than three decades since Sir James Dyson first introduced his cyclonic bagless vacuum to the world, and today, many competing major manufacturers such as Vax and Bosch have produced their own bagless vacuums. Below, you'll find the pros and cons of choosing a bagless model over traditional bagged versions.
Regardless of what you end up buying, make sure it's a vacuum cleaner that will suck up dust and not skip over it. Our independent reviews reveal the best on the market, and we've tested more than 150 models.

Bagless versus bagged vacuums
Bagless vacuum cleaners trap all the dust and dirt from your floors inside a canister that you then empty into a bin. This saves you having to replace bags, which can be costly and fiddly.
The big advantage of a bagless vacuum is the reduced running cost. The ongoing cost of replacement bags for a bagged vacuum cleaner can mount up as the years go on.
On the downside, bagless vacuums tend to have smaller dust capacities than bagged models. The average upright bagged vacuum will hold around 4.2 litres of dust, but bagless upright vacuums hold an average of 2.6 litres – considerably less.
Emptying a bagless vacuum cleaner can also be a messy job, potentially making them a bad choice for those with allergies. You need to be careful not to spill anything as you remove and tip out the dust canister into your bin. Alternatively, you could empty the canister into an outside bin so that the fine dust and allergens don't escape into your home.
We test every vac to see how well it retains the dust particles and allergens that you vacuum up – as the last thing you want is a vacuum cleaner that leaks.
But it’s not just how hygienic it is to empty that needs to be considered by people with allergies.
Our tests show that, on average, bagged vacuums tend to be slightly better at retaining allergens and dust than their bagless counterparts. There are bagless models that buck this trend, however, so if you're intent on having a bagless model and demand excellent allergen retention, you will still be able to find a worthy model using our vacuum cleaner reviews.
Hepa and S-class filters can help a vacuum retain dust and allergens, but they aren't always a guarantee of good performance. To make sure you get a vacuum that keeps everything in, search our expert reviews for vacuum cleaners with four or more stars for allergen retention.
