Appearance and Design

Split image of the Shark NV702UK

The Shark NV702UK looks a little clunky, but is sturdy and robust in its plastic construction. We’re impressed by the 5.25kg weight, which is on the lighter side for an upright. In comparison, the Shark NZ801UKT is a heftier 6.5kg.

However, the 1.1 litre capacity isn’t overly large. It’s more than you get on most cordless vacs, but other uprights offer more. For example, the Dyson Ball Animal 2 has 1.8 litres, and the Vax Air Lift Steerable Advance also pips it with 1.5 litres.

Like most recent Shark vacuums, the NV702UK has a soft roller and bristle brush in the same floorhead (DuoClean) to cover different floor types. This removes the hassle of needing to swap floorheads when switching from carpets to hard floors.

The second useful feature is the Lift-Away technology, which allows you to convert it to a portable cleaner. The dirt canister and hose pull away, reducing the weight further to 3.4kg and adding to the versatility of this upright vac.

Shark has enough confidence in this product to offer a 5-year guarantee when you register your product. It’s longer than you’d often find with a vacuum cleaner, so it’s worth taking advantage of.

Manoeuvrability and Ease of Use

For an upright, the Shark DuoClean is easy enough to use in a furnished home. It’s not as agile as a cordless, as you’d expect, but we don’t have any major complaints. The main bonus is that the DuoClean floorhead keeps it simple to clean a range of surfaces.

The power switch has options for hard floors or carpets, which changes the brush bar settings accordingly. You can also adjust the suction power via another control on the handle. It’s all very intuitive and user-friendly.

We also like the weight distribution. Most of it is at the bottom of the vacuum, so it doesn’t feel too heavy for covering large areas. Coupled with the swivel steering, it makes for a pleasant cleaning experience.

Although we should note it can be tricky to get it to go where you want to when using the higher setting. The strong suction can cause resistance, but swapping to the “min” mode will aid manoeuvrability.

Of course, the Lift-Away feature is a useful extra. You can remove the hose and main body of the vacuum to convert it into a portable cleaner. It’s much easier for accessing awkward or high-up areas, especially as the weight drops to 3.4kg in this setup. But you do still have to hold the canister and the hose while working around the power cord, too.

We should also note this model doesn’t use powered Lift-Away technology. When used as a portable cleaner the motorised tools won’t have any power, which means the brush rolls won’t spin. But with powered Lift-Away (found on more expensive Shark models,) the motorised tools will still work as they do in the main setup.

Finally, at 8m the cable is an average length. You will find you need to swap plug sockets between rooms, and the manual cord rewind isn’t as convenient as automatic alternatives.


The Shark DuoClean NV702UK has a foam and felt filter kit with an exceptional anti-allergen seal. It claims to trap 99.9% of dust and allergens to stop them from being released back into the air you breathe.

It’s a good option if you have dust allergies, but we’d still recommend a bagged model with a HEPA filter for allergy sufferers.

Still, the Shark’s washable filters are effective while being low maintenance. They need rinsing with cold water once a month, and the post-motor filter requires an annual clean.

Emptying and Cleaning

The emptying process is straightforward for the Shark DuoClean, but not the most hygienic.

There’s one button to release the dust cup from the machine, and another to open it for emptying. Unfortunately, there’s no internal collar to push dirt out, so you may have to tap the canister or pull clumps by hand.

The lint screen will also need cleaning by hand, and keep an eye on the brush roll as it doesn’t have anti-wrap technology. In all honesty, it’s not our favourite method for emptying a vacuum.

Tools and Accessories

The Shark NV702UK has a limited range of accessories, letting the DuoClean floorhead take centre stage instead. But you still get an additional crevice tool and multi-surface tool with detachable bristles.


There’s no doubt the DuoClean is an excellent floorhead. The two rotating brushes are a soft velvet-like brush for hard floors and a stiff bristle brush for carpets. The idea being this versatile floorhead can manage all surfaces, removing the need for multiple brush heads.

The soft brush sits at the front, allowing direct contact with the floor so it pulls particles in rather than pushing them away. And the generous 30.5cm width ensures it covers a large cleaning path while headlights make it easier to see dust and dirt.

For maintenance, there’s a brush roll indicator light to warn of problems, such as blockages or overheating. The two brush rolls are accessible for cleaning by removing the covers.

Other Tools and Accessories

Also included with the Shark DuoClean NV702UK is a standard crevice tool and the multi-surface tool. The latter is an upholstery tool with detachable stiff bristles, so you can add them on for removing stubborn dirt.

It’s not the best range of accessories, but they both come in useful on various surfaces around the home. Particularly as they can both attach to the wand, or straight onto the handle.

We should note there isn’t a pet tool included with this model. If you’ve got pets, we recommend opting for the True Pet Version, the NV702UKT, as this includes an extra attachment. You may also want to look at our guide to the best pet vacuum cleaners.

Suction Power and Cleaning Performance

The Shark DuoClean NV702UK offers decent overall cleaning without being exceptional. While it’s solid on most hard floors, it struggles more on carpets. Even so, the Shark manages to clean most messes without problems.

The DuoClean floorhead makes a good seal on carpet areas, aiding performance but hindering movement. It’s worse when you pull the cleaner back towards you or change direction.

There’s a Min or Max mode to choose from for the suction power, and the Min mode is the only real option for carpets. Otherwise, it’s too difficult to control the movement of the vacuum. It’s a shame to lose the extra cleaning power that carpets often need. Max mode is best reserved for hard floors to ensure debris gets sucked up and contained.

Then there’s an extra option to change the settings to suit hard floors or carpets. The brush roll spins in both modes, but it’s faster in the carpet setting. This somewhat makes up for needing to use Min mode. The brush roll is slower in the hard floor setting to avoid sending debris scattering across the room.

Unlike some other upright models, the Shark is quiet in both modes. We also like how this vacuum maintains consistent cleaning performance when the dirt container is getting full. You can make most of the 1.1 litre capacity without needing to empty it to maintain power.


Carpets aren’t a strong point for this Shark vacuum cleaner – particularly if you need to reduce suction power to push it.

Even with the increased speed of the brush roll in carpet mode, it doesn’t manage effective deep cleaning. It also feels cumbersome to manoeuvre, which could be tiring after a few rooms.

It copes better with larger debris pick up on carpets, but stumbles on fine particles. It will get there if you keep trying, but other uprights can manage it with less effort. Take a look at our list of the best carpet vacuums for some examples.

Hard Floors

The Shark comes into its own on hardwood and tile flooring. It feels lightweight and glides seamlessly across the surface while still being ruthless on dirt. The DuoClean floorhead picks up larger debris from its wide cleaning path in a single sweep. It also excels at pulling out dust from between floorboards.

It’s not as capable on laminate floors and will need an extra sweep or two. With that said, if you’ve got lots of hard floors in your home this model is a strong contender.


The Lift-Away technology is the star of the show for stairs. With just the pod section to manoeuvre, it’s lighter and smaller to manage on steps. And the carry handle is convenient for lifting.

However, there isn’t a small motorised floorhead, which creates an issue. The main floorhead is quite wide, rendering it bulky and awkward for cleaning stairs. You could use the multi-surface tool, but the lack of a rotating brush bar means it’s a less effective clean.

Pet Hair

The suction power of the Shark DuoClean NC702UK does a fair job with pet hair. And the multi-surface tool has stiff bristles for cleaning stubborn pet mess, like muddy paw prints.

But that’s as far as the pet hair capabilities go. Without the motorised pet tool, we can’t recommend this model to pet owners. The True Pet model (NV702UKT) includes the tool as standard, so it’s a better choice for anyone with animals in their home.

Price and Value for Money

The Shark DuoClean NV702UK is a relatively inexpensive upright option that manages mess on hard floors without breaking a sweat, particularly if you can find it on offer.

Although it does lack attachments and has movability issues on carpets, so you could find cheaper alternatives that offer better all-round cleaning. For example, the Shark NV602UKT brings more versatility with its enhanced attachments.

Even so, the NV702UK still offers a decent amount of cleaning power for the money. It’s an upright cleaner with the bonus of having a portable mode and a few accessories thrown in. And with some basic maintenance, you shouldn’t have any recurring costs. We also think the long 5-year warranty adds to the value of this vacuum.

Comparison With Other Vacuums

Shark NV702UK vs Shark NZ801UK

Both of these Shark vacuum cleaners have the same 8m power cord and 750w motor, along with a similar design. At 5.25kg, the original NV702UK is over a kilo lighter while offering a larger 1.1 litre capacity compared to 0.83 litres.

The main difference is the NZ801UK’s upgraded floorhead with anti-hair wrap technology. And, unlike the NV702UK, it has powered Lift-Away. This means you still get brush bar power when using the pod on its own. Yet in this setup, it’s lighter than the NV702UK, weighing just 2.5kg vs 3.4kg.

The lower price, larger capacity, and lighter overall weight make the NV702UK an appealing prospect. But without the Shark anti hair wrap technology, you’d need to keep an eye on any tangles forming on the brush bar. The extra features on the NZ801UK are welcome additions, so it comes down to what you’re looking for in a vacuum cleaner.

Shark NV702UK vs Dyson Ball Animal 2

The Dyson Ball Animal 2 is similarly priced to the Shark and is another strong contender in the upright market. It has a bigger 900w motor, a longer 10.8m power cord, and a larger 1.8 litre capacity. The trade-off is a smaller 25.5cm floorhead, and an extra couple of kilos in weight.

We rate the cleaning performance of the Dyson higher than the Shark, although it does struggle with fine dust. It has a better range of attachments, which would have been nice to see with the Shark. The turbo pet tool is the biggest bonus, as it makes the Dyson more suited to people with pets.

Overall, we think the Dyson Ball Animal 2 offers more cleaning power for the money. But the Lift-Away feature with the Shark is something that many people will find useful.

With hundreds of upright vacuum cleaners to choose from, we have to admit that the Shark NV702UK doesn’t blow us away. It offers solid cleaning performance, but there are some issues that are hard to overlook.

The struggles on carpets and lack of accessories are our biggest gripes, along with the somewhat messy emptying process. The large DuoClean floorhead is a fantastic feature, but even the extra width won’t speed up having to do extra sweeps for finer debris. That said, it can handle a range of surfaces without too much hassle.

It’s one to consider if you want a solid all-rounder for a reasonable price and don’t want a cordless vacuum cleaner. But if you’ve got a home with pets or large areas of carpet, it’s probably not the best choice.
