Dyson Gen5 Detect vs V15 Detect

Gen5 Detect and V15 Detect side by side

The table below compares the two models on the points most buyers ask about. V15 figures come from the V15 Detect Animal listing we use in our guides, plus Dyson's widely published launch figure for suction. Gen5 figures are the ones Dyson has quoted at launch. Dyson revises editions and bundles often, so check the current specification on Dyson's site or the retailer listing before you buy.

Suction and cleaning power

Dyson quotes 280 air watts for the Gen5 Detect, against the 230 air watts it quoted for the V15 Detect at launch. Air watts combine airflow and suction, so a higher figure means more pulling power at the floor head in the highest mode. In practice you only use full power for short bursts on deep carpet or rugs, and both machines spend most of their time in Auto or Eco.

Both models use Auto mode with a motorised head that senses brush bar resistance and adjusts power to the floor type, and both use the piezo sensor to raise suction when it detects more dust. The V15 Detect Animal listing describes its High Torque head monitoring brush bar resistance 360 times a second. For most UK homes with a mix of carpet and hard floors, the V15 already has more than enough suction. The Gen5's extra headroom matters most on thick pile carpets and for owners of long-haired pets.

Runtime, battery and controls

Dyson quotes up to 70 minutes for the Gen5 Detect and up to 60 minutes for the V15 Detect. Those maximums apply in the lowest power mode, usually with a non-motorised tool. With the main motorised head in Auto, both run for considerably less, and in Boost both run for only a few minutes. Plan around Auto mode figures rather than the headline number. Our runtime planner helps you work out whether one charge covers your floor area.

Both machines use a click-in battery that you can remove without tools, so a spare battery is an option on either. The biggest day to day difference is the switch. The V15 has a trigger you hold while cleaning. The Gen5 Detect uses a push button, so the motor keeps running without a finger held down. Some people find this easier on the hand during a long clean; others like the trigger because the motor stops the moment you let go, which saves battery between rooms.

Note:Use only the Dyson charger or a compatible one made for your model. Do not use a battery that is damaged, swollen or has been dropped hard, and recycle old packs at a battery recycling point, never in household waste.

Filtration and bin

The V15 Detect Animal listing gives a HEPA filter type with a washable filter, and Dyson describes its machines as having whole-machine filtration. For the Gen5 Detect, Dyson describes fully sealed HEPA filtration. As specifications, both are designed to capture very small particles and keep them inside the machine rather than letting air leak past the filter. We describe filtration only as the maker states it; neither model should be bought on any promise beyond that.

The V15 Detect bin holds 0.76 litres. The Gen5 Detect bin is of a broadly similar size, so emptying frequency will feel much the same in a typical house. Both use Dyson's point and shoot style emptying, where you push a lever to slide the bin open over the dustbin. If bin size is your priority, look at the Outsize versions instead; our Gen5 Outsize vs Gen5 Detect comparison covers that.

Heads, tools and the Detect features

Both machines are built around Dyson's Detect features. The particle sensor counts and sizes dust as it passes through, and the LCD screen shows the counts, the power mode and the remaining runtime. A lit soft roller head shows fine dust on hard floors: on the V15 this is the Laser Slim Fluffy head on many editions, and on the Gen5 Detect it is the Fluffy Optic head. Our laser head and particle sensor explainer covers how these work.

The V15 Detect Animal listing includes a High Torque cleaner head with a de-tangling comb and a Hair screw tool with a conical brush bar. The Gen5 Detect comes with a motorised de-tangling floor head and the Fluffy Optic head in most UK bundles, and Dyson has described a tool built into the wand on some versions. Tool sets differ by edition, so compare the box contents rather than the model name alone. Our guide to Dyson cleaner heads explains what each head is for.

Weight and handling

The V15 Detect Animal listing gives 3 kg. The Gen5 Detect is a similar full-size machine, so neither is a lightweight stick. Both carry the motor and battery in the handle, which makes them feel top heavy when you lift the wand to clean cobwebs or curtains. If weight is your main concern, a slimmer model such as the V12 Detect Slim or a lighter rival will suit you better; see our lightweight cordless vacuum guide.

On the floor, both glide well because the motorised heads pull forward slightly. As handhelds for stairs and sofas, both are heavier than older V8 machines, but the extra power helps with hair on carpeted stairs.

Is the Gen5 worth it over a discounted V15?

For most households, a V15 Detect at a good discount is the better value. It has the particle sensor, the screen, a lit head on many editions, a removable battery and enough suction for carpets and pet hair. The Gen5 Detect adds more suction, a longer quoted runtime, the push button and sealed HEPA filtration as Dyson describes it.

Choose the Gen5 Detect if you have a larger home with lots of carpet, want the longest single battery runtime in a standard size Dyson, or prefer not to hold a trigger. Choose the V15 Detect if the price gap is large, your home is small to medium, or you already own V15 compatible accessories. Whichever you choose, buy from a seller that provides the full Dyson warranty, and register the machine with Dyson.

• Large home, lots of carpet, dislikes triggers: Gen5 Detect
• Small or medium home, value matters: discounted V15 Detect
• Want the lightest Detect model: look at the V12 Detect Slim instead

Frequently asked questions

Is the Gen5 Detect much more powerful than the V15? Dyson quotes 280 AW for the Gen5 Detect and quoted 230 AW for the V15 Detect at launch. That is a real increase at full power, but in everyday Auto and Eco use the difference is smaller than the headline numbers suggest.

Do V15 accessories fit the Gen5 Detect? Dyson has changed some connections over the years, and compatibility depends on the tool and edition. Check Dyson's compatibility information on its support pages before buying extra tools for either model.

Does the Gen5 Detect have a trigger? No. Dyson moved to a push button on the Gen5 Detect, so the motor keeps running without holding a trigger. The V15 Detect keeps the trigger.

Which has the longer runtime? Dyson quotes up to 70 minutes for the Gen5 Detect and up to 60 minutes for the V15 Detect, both in the lowest mode. Runtime with the motorised head in Auto is shorter on both.
