Vacuum cleaners buying guide


Vacuum cleaners vary from models that pick up dog hairs to ones that aid allergy sufferers. To help you choose the right cleaner, here are a few pointers you might like to consider. View our range of vacuum cleaners.

Should I buy a cylinder or upright cleaner?

It's often a matter of taste but each type has its own advantages.


How do they work?

In upright cleaners the motor is situated in the head of the cleaner. It drives a fan which sucks up air and dust into the dust bag via a tube. The dirt is retained in the bag, and filtered air passes over the motor before it is pushed out of the cleaner. As well as suction power, upright cleaners have revolving, belt-driven brushes and sometimes an agitator beater bar that help to loosen and sweep up ingrained dirt from the carpet.

In cylinder cleaners the motor turns a fan that in turn sucks up dust and dirt from the cleaning head, through the hose and into the dust bag. Cylinder cleaners rely entirely on suction to draw the dust in, so they tend to be more powerful (that is, of a higher wattage) than uprights.     

Bag or bagless?

This is a highly debatable point between certain manufacturers. Bagged cleaners are usually cheaper than bagless models, but you have the added expense of purchasing additional bags. Some have self-sealing bags, making disposal less messy – a boon for allergy sufferers.


With bagless there’s no fuss with inserting fresh bags, and though the technology makes the initial outlay expensive, in the long run they can be cheaper.

Some bagless models are easier and cleaner to empty, and come with anti-bacterial protection which substantially reduces house dust mite and cat allergen content. These models carry the British Allergy Association seal of approval.

Type of flooring

The main type of flooring your home has should dictate the type of cleaner you buy:

  • Wooden, tiled or vinyl: cylinder cleaners are best.

  • Loop pile carpet: either, but make sure you turn any turbo roller attachment off as it may flatten or damage the pile.
  • Cut pile carpet: upright, or cylinder with a turbo brush attachment. 


All cleaners have some form of filtration system but there are some models that have more sophisticated filters or ones suitable for those with either allergies or pets.

  • Stage filters: usually vary between 3 and 7 stages. A typical 4-stage filter would comprise a double-skinned bag (2 stages), a filter between the dust bag and motor chambers, and a final filter.
  • Lifetime filters: no need to change the filter during the lifetime of the machine – normally 7-10 years. 

  • HEPA (High Efficiency Particulate Air): also known as S-Class, these retain even the smallest of allergy-causing particles. Look out for those machines that have been given the British Allergy Foundation’s seal of approval.
  • Charcoal filter: with a charcoal layer that removes any nasty smells. Particularly suitable if you have pets. 

Power and wattage

The higher the wattage the more powerful the cleaner, but this is more important on cylinder machines as the dust has further to travel up the tube. It’s not just the wattage though: airflow and the design of the machine help improve the suction power as well. 

On upright cleaners it’s the type of brush that makes more of a difference. Many models have variable power – useful on upholstery, curtains or rugs.


Most cleaners come with three attachments: crevice tool, upholstery and dusting brushes. Some machines have an additional turbo brush, often powered separately, for extra suction. They’re good on cut pile carpets and for picking up pet hairs. For wooden or tiled floors consider a horsehair/parquet brush. For hard-to-reach areas look to see if the cleaner has an extendable tube.

Other points to consider

  • Bag capacity: these vary enormously. Opt for a larger capacity if you have a big area to vacuum.
  • Cable length: if you have a large house then look at the length of cable supplied. 

  • Weight: important for less abled people or if there are stairs involved.
