Shark vs Dyson cordless vacuums

Shark and Dyson models side by side

The table uses each maker's listing figures. Runtimes are maximums, usually measured in the lowest power mode with a non-motorised tool, so expect less with the main floor head fitted. Where a listing does not state a figure, we say so rather than guess.

Weight and handling

Weight matters most on stairs and when you lift the vacuum to clean high up. The Shark Stratos Pet Pro lists an in-use weight of 2.16 kg, which is light for a full-size stick with a motorised head. The Dyson V15 Detect Animal is listed at 3 kg and the V8 Origin at about 2.5 kg. Makers do not always measure weight the same way, so treat small gaps with caution, but the V15 is clearly the heavier machine.

Shark's Flexology wand, listed on the PowerDetect, bends in the middle so you can reach under sofas and beds without crouching, and lets the vacuum fold over to stand on its own. Dyson wands are straight and the machines are designed to hang on a wall dock. If you have no wall space for a dock, the Shark approach is easier to store. For more on handling, see our guide to the best lightweight cordless vacuums.

Floor heads and hair

Both brands now focus on stopping hair from wrapping around the brush. Shark's Anti Hair Wrap Plus on the PowerDetect uses a chevron brush-roll with internal combs that remove hair as you clean. The Stratos Pet Pro uses a DuoClean head with two motorised brush-rolls, which helps it move from carpet to hard floor without changing heads.

Dyson's V15 Detect Animal ships with a High Torque head whose de-tangling comb clears hair from the brush bar, plus a Hair screw tool with a conical brush bar for sofas and pet beds. The V8 Origin uses a De-tangling Motorbar head. Dyson's Detect range is also widely sold with a soft roller head with a light for hard floors, but check what is in the box for the exact bundle you buy, as the Animal listing here does not include one.

Sensors and smart features

The Dyson V15 Detect has a piezo sensor that sizes and counts dust particles and raises suction when it finds more, with an LCD screen that shows what has been picked up. In Auto mode, Dyson's DLS system monitors brush bar resistance 360 times a second to adapt power to the floor type.

Shark's PowerDetect bundles several sensors. DirtDetect raises suction when it senses dirt, FloorDetect changes brush-roll speed between carpet and hard floor, EdgeDetect doubles suction at edges and skirting boards, and DirectionDetect keeps suction up when you pull the vacuum backwards. The Stratos Pet Pro has Clean Sense IQ, which adjusts power to the dirt it senses. Neither brand's sensor makes up for a clogged filter, so maintenance still matters.

Batteries, runtime and docks

The Shark Stratos Pet Pro has a removable battery that charges on or off the vacuum, so you can charge it at any socket. Dyson's V8 Origin charges on its wall dock and takes up to 5 hours for a full charge. Dyson's V15 Detect is widely documented as having a click-in battery that can be swapped, but spares are sold separately, so check Dyson's current specification before relying on that.

Maker runtimes are best-case figures. With a motorised floor head and medium or boost power, most sticks run for a fraction of the headline time. Use our runtime planner to see whether one charge will cover your home, and read cordless vacuum runtime explained for how makers measure it.

Note:Use only the maker's charger or an approved replacement, never use a battery that is swollen or damaged, and take old lithium packs to a battery recycling point rather than household waste.

Spare parts, guarantees and running costs

Both brands sell replacement batteries, filters and floor heads through their own UK websites and through retailers, which helps a stick vacuum last longer. Dyson has sold V8, V10, V11 and V15 parts for many years, and third-party parts are common for older Dyson models. Shark parts are also widely available, though names vary between ranges, so check your model number before ordering.

Shark lists a 5-year guarantee on the Stratos Pet Pro when you register it, with 2 years on the battery. Dyson's guarantee length depends on the model and where you buy, so check Dyson's current terms. Running costs in electricity are small for both: a cordless battery stores well under a tenth of a kilowatt hour. Our battery energy calculator works it out from the voltage and capacity.

• Washable filters: both brands list washable filters on many models, which cuts replacement needs.
• Batteries: removable or click-in packs are easier to replace than fixed ones.
• Heads: buying a second head later is usually possible on both brands.

Which brand suits which home

Choose a Shark such as the Stratos Pet Pro or PowerDetect if you want a lighter stick, a bendable wand for low furniture, freestanding storage and a long registered guarantee. Choose a Dyson V15 Detect if you want a bigger bin, a dust sensor with on-screen counts and a wide choice of heads and tools. The Dyson V8 Origin is a simpler, lighter Dyson with a shorter runtime that suits flats and smaller homes.

Frequently asked questions

Is Shark cordless as good as Dyson? On paper, Shark's current sticks match Dyson on the features most people use: motorised anti-tangle heads, dirt sensing and removable batteries. Dyson's V15 Detect adds a particle sensor with a screen and a larger bin. Which is better depends on your floors, home size and how much weight you are happy to lift.

Which is lighter, Shark or Dyson? Among the models here, the Shark Stratos Pet Pro lists 2.16 kg in use, against 3 kg listed for the Dyson V15 Detect Animal and about 2.5 kg for the V8 Origin. Makers measure weight in different ways, so check the in-use figure on each listing.

Does the Dyson V15 beat Shark on suction? Dyson and Shark do not publish suction in the same unit, so a direct comparison from listings is not possible. Head design, brush speed and sealing affect pick-up as much as the number. Our air watts explainer covers why.

Can I swap batteries on Shark and Dyson sticks? The Shark Stratos Pet Pro has a removable battery that charges on or off the machine. Newer Dysons such as the V15 Detect are widely documented as having click-in batteries, while older V8 models use a screw-fixed pack. Check the maker's specification for your exact model.
