Our pick: Shark Stratos IZ400UK
Average price in the past six months: £315
Cheapest price in the past six months: £209*
- Bagless and cordless stick vacuum cleaner
- 0.9 litre dust capacity
- Weighs 4.1kg
We like: Its filters retain allergens well
We don't like: Fairly noisy
Shark says that the enhanced brush-roll design on the Stratos IZ400UKT delivers its best ever hair pick-up, which will be a relief if you spend half your life cutting pet hair and your family's tresses off your brush head's roller.
Although it has a LED lamp in the floorhead to help illuminate dust and pet hair the 'Clean Sense IQ' feature automatically senses invisible dirt and adjusts the cleaning power so you don't have to be that vigilant.
In the box you’ll find a crevice tool, multi-surface tool, pet tool, accessory bag, lithium-Ion battery and a charger.

Cordless vacuum cleaner deals
Miele Triflex HX2
Average price in the past six months: £561
Cheapest price in the past six months: £450*
- Bagless and cordless stick vacuum cleaner
- 0.6 litre dust capacity
- Weighs 3.8kg
We like: Its quiet
We don't like: Fairly slow at charging
Although the Triflex HX2 has been around for a few years it has some unique features and a stylish look, we can see why you’d be tempted. Unusually you can attach the power unit to the top or bottom of the vacuum depending on whether you will be crouching or reaching to clean today's dust trap. It can also be removed from the main body and used as a handheld vacuum, handy for vacuuming furniture or even the interior of your car.
It comes with an electro brush, upholstery nozzle, crevice tool, a carpet brush bar and a separate nozzle holder for storing all accessories and tools. If you have a dedicated space for your vacuum, the unit stand can be mounted on a wall.
Is the power unit's movable position a help or a hindrance? Our full Miele Triflex HX2 review reveals all.

We like: Long run time
We don't like: Not the quietest

There's a detachable handheld unit and a host of nozzles and heads, including a motorised floor bar, an anti-tangle head for removing pet hair, a furniture and upholstery nozzle, plus a crevice tool. You’ll also find a charging cable that can be used with or without the wall dock.

Corded vacuum cleaner deals
Shark NZ780UKT
Average price in the past six months: £234.66
Cheapest price in the past six months: £170*
- Bagless and upright, corded vacuum cleaner
- 3.8 litre dust capacity
- Weighs 6.6kg
We like: A fab choice for pet owners
We don't like: It's a bit messy to empty
You can't beat a corded vacuum cleaner for sustained cleaning power, without the faff of charging the battery and emptying the dust collector all the time. This upright model combines a decent-sized dust canister with an anti-hair wrap roller to have you cleaning up after your pets speedily.
The floor head has two modes – carpet and hard floors – and it comes with a mini turbo brush for pet hair, an upholstery nozzle and a crevice tool. It also has a removable unit that can be used on stairs and other situations that are too awkward for upright mode.

Cheapest price in the past six months: £299*
- Bagged and corded cylinder vacuum cleaner

This is an aesthetically pleasing corded and bagged vacuum cleaner from the Miele Guard L1 series. All models come with a universal floor head, dusting brush and a combi upholstery and crevice tool.
It has an impressively long reach of almost 12 metres, so you’ll have no problems cleaning even large areas in your home. This allergy version uses a HEPA AirClean filter to keep nasty allergens locked away.

Robot vacuum cleaner deals
Shark Matrix Plus 2-in-1 Self-Empty Robot Vacuum & Mop RV2620WAUK
Average price in the past six months: £422.10
Cheapest price in the past six months: £330*
- Robot vacuum cleaner
- 0.23 litre dust capacity
We like: Easy to use
We don't like: Bulky
If you're in the market for a robot vacuum cleaner, Shark's Matrix Plus 2-in-1 Self-Empty Robot Vacuum & Mop RV2620WAUK is currently on offer.
It comes with charging and self-empty station, two side brushes and a couple of washable mopping pads. It doesn't take up much space – the unit itself is 9 x 34cm, though the 230ml dust tank will need emptying fairly regularly.
Plus, you can set up virtual barriers in the easy-to-use SharkClean app to help it navigate furniture and other obstacles.

Dyson 360 Vis Nav Robot Vacuum
Average price in the past six months: £970.90
Cheapest price in the past six months: £599.99*
- Robot vacuum cleaner
- 0.5 litre dust capacity
We like: Very easy to use
We don't like: Not the quietest
The Dyson 360 Vis Nav Robot Vacuum doesn't come cheap, so it's great to see this one on offer.
It comes with a charging station, and is controlled with MyDyson app (note that you can't set it up without a wi-fi connection).
The dust container has a sliding button that makes it easy to empty. However, because the bottom of the dust container opens when you slide the button, the dirt drops out very rapidly and causes a cloud of fine dust. We'd recommend dropping any dirt, particularly fine dirt, into a deep bin to stop the dust cloud getting everywhere.

Eufy Clean X8 Pro with Self-Empty Station
Average price in the past six months: £456.11
Cheapest price in the past six months: £309*
- Robot vacuum cleaner
- 2.5 litre dust capacity
We like: Very easy to use and clean
We don't like: Struggles to climb high ledges
Eufy specialises in home security systems and robot vacuum cleaners, with the X8 Pro one of its more affordable vacs. In addition to the vacuum cleaning, it also has a mop function.
It's able to dock into its self-empty station without the user having to intervene, and it cleans the roller brushes every time it does so. You can adjust the frequency of emptying into the charging station via the app if you don't want this after every clean.

How to spot a good deal on a vacuum cleaner
Andrew Laughlin, Which? vacuum cleaner expert, says:
With some vacuums almost perennially on 'special offer', it can be hard to know which deals are genuine money savers.
Stick to these golden rules to help get the best value with your next purchase.
- Don't fall for features and accessories Some models come with impressive-sounding features. Think Flexology (a flexible cleaning tube), or Lift-Away (a removable handheld unit), or Vax's QuickClean (also a removable unit). While useful, you'll most likely find similar features across many other brands, just with more conventional names. Models in the same range (eg the Samsung Jet range) usually have the same core machine – the only difference is the accessories and supplied floor heads. An entry-level model typically costs about £100 less than a premium model with all the accessories.
- Check the price of similar models Many vacs have a basic package and a more expensive pet variant, which comes with a mini-tool for cleaning up after your furry friends. In some circumstances, you'd be better off buying the basic model and the pet tool separately. However, always check the prices of variants, as you might find the pet version on offer for less than the basic model.
- Check out the latest price data If a deal seems too good to be true, you can use price comparison sites such as PriceRunner and PriceSpy to check historical price data. The data should reveal how regularly a vacuum goes on sale (if it's on 'special offer' for most of the year, the offer isn't all that special) and whether the 'before' price is accurate. It's worth doing a quick Google search too, as not all retailers' price feeds are picked up by these sites.
Dyson vacuum deals
Based on historical pricing data, we think these prices represent genuinely good savings on some of Dyson's most popular cordless models:
- Dyson Gen5detect Cordless – anything less than £699
- Dyson V15 Detect Absolute – anything less than £550 (£499 for the Animal model)
- Dyson V12 Detect Slim Absolute – anything less than £449
- Dyson Outsize Absolute – anything less than £699
- Dyson V11 Absolute – anything less than £599 (£499 for the Animal model)
- Dyson Cyclone V10Absolute – anything less than £399 (£349 for the Animal model)
- Dyson V8 Animal – anything less than £329
- Dyson V7 Animal – anything less than £249
We've noticed that prices can rise in the months before big sales events such as Black Friday, Christmas sales or Cyber Monday, creating the illusion of huge savings on the day.
Always check PriceRunner or PriceSpy to compare historical prices to find out of the model you're after is actually being sold at a low price.
Shark vacuum deals
Based on historical data, we think these prices represent genuinely good savings on some of Shark's most popular models:
- Shark HZ3000UKT – anything under £249
- Shark IZ300UK – anything under £299
- Shark ICZ160UK – anything under £299
- Shark IZ201UK – anything under £249
- Shark NV702UK – anything under £189
- Shark NV602UK – anything under £169
- Shark HZ500UK – anything under £179
Also keep in mind that cordless Sharks are sold with one, two or sometimes even three batteries.
If you opt for a package with extra batteries, bear in mind that you can buy spare batteries from the Shark website for around £70, so the deal only makes sense if the package is a similar price to the single-battery model.
If you live in a smaller property, you probably don't need extra batteries, as a single charge will last long enough to vacuum your home in one go. Any battery faults should be covered by the manufacturer's guarantee for the first two years.
Samsung vacuum deals
If you're looking to replace your old Samsung with a new model, don't forget to check the Samsung website for trade-in deals for your old appliance. They'll take your old vacuum, price it and then you'll be able to put the money towards a new model.
How to recycle your old vacuum cleaner
Some retailers will offer to recycle your old vacuum cleaner, although they can sometimes charge a fee for doing so.
Our guide on how to recycle electrical items will help you asses your options.
