Dyson V11 vs V15 Detect: Is the V15 Worth It?
We may earn a commission when you buy through links on this page, at no extra cost to you. How this works.
The Dyson V15 Detect and V11 share the same basic body, bin size and 60-minute claimed runtime. What the V15 adds is a laser head that reveals dust on hard floors, a particle sensor that counts what you pick up, an anti-tangle floor head, a Hair Screw tool, more suction and fully sealed HEPA filtration. Whether that is worth roughly £150 more depends on your floors, pets and allergies.
Quick answer: Pick the V11 if you want strong all-round cleaning at the lowest price and do not have long-haired pets or allergies. Pick the V15 Detect if you have hard floors (the laser genuinely helps), long hair in the house, or allergy sufferers who benefit from the HEPA-sealed system.

Exact tools vary by bundle; V15 bundles almost always include the laser head and Hair Screw tool, while V11 bundles vary widely.
Round 1: suction and cleaning
The V15's motor produces around 230–240AW against the V11's 185AW. Independent reviews find both clean carpets very well; the V15 has an edge on deep pile, and its auto mode reacts to the amount of dust detected rather than just floor resistance.
The biggest real-world difference is the laser on the V15's soft roller head. It projects a line of green light across the floor that makes fine dust and pet hair visible on hard floors. Owners commonly say it changes how thoroughly they clean, because they can see what they are missing. On carpet the laser is less useful. Read more in our V15 Detect review.
Winner: V15, especially on hard floors.
Round 2: hair and pets
The V11's High Torque head is effective, but long hair still wraps round the brush and needs cutting off. The V15's Digital Motorbar has a comb that de-tangles the roller as it spins, and the Hair Screw tool's conical brush pushes hair into the bin rather than wrapping it. For homes with long-haired pets or people, this is the most practical upgrade. See best cordless hoover for long hair.
Winner: V15.
Round 3: battery and runtime
Both claim up to 60 minutes and both have click-in batteries you can swap for a spare. Real-world runtime with the floor head is similar, at roughly 35–45 minutes in auto or medium mode. The V15's more powerful motor can drain the pack slightly faster in boost. Both show remaining runtime on the LCD. See cordless hoover battery life.
Winner: Draw.
Round 4: bin and filtration
Bins are the same size. Filtration is the difference: the V15 is HEPA-sealed, meaning the whole machine is sealed so air cannot bypass the filter, and Dyson claims it captures 99.99% of particles down to 0.1 microns. The V11 has sealed whole-machine filtration but Dyson positions the V15 as the allergy choice. If anyone in the house has asthma or hay fever, the V15 is the safer pick; our HEPA filters explained guide covers why sealing matters.
Winner: V15.
Round 5: ergonomics and screen
Weight and balance are almost identical, at around 3kg. Both use a trigger. The V15's LCD adds a particle count by size, which some people find motivating and others ignore. Neither model stands on its own. If weight matters more than anything, look at the V12 Detect Slim, compared in V12 vs V15.
Winner: Draw.
Round 6: price and value
The V11 typically costs around £150 less, and the gap is often wider in sales. The V15 regularly drops toward £450–£500 around Black Friday and when newer models launch, and refurbished V15s from Dyson's outlet can approach new V11 prices. See Dyson cordless hoover sale for typical patterns.
Winner: V11 on price.
Which is better for your home?
| Your situation | Better choice | Why |
|---|---|---|
| Mostly carpets, no pets | V11 | Excellent on carpet for less money |
| Mostly hard floors | V15 | Laser reveals fine dust |
| Long-haired pets or people | V15 | Anti-tangle Motorbar and Hair Screw tool |
| Allergy sufferer at home | V15 | HEPA-sealed whole machine |
| Tight budget | V11 | Typically around £150 cheaper |
| Want data on what you pick up | V15 | Particle counts on the LCD |
Long-term ownership and running costs
Ownership costs are similar. Both use washable filters, both have click-in batteries on current versions, and both share Dyson's tool connector, so accessories bought for one generally fit the other. A spare battery is the most useful accessory for a large home with either model.
The V11 is the older design, which means mature parts supply and lots of discounted stock and refurbished units. The V15 has also been on sale for several years now, so it is no longer a cutting-edge launch price; newer Dyson flagships have pushed it down the range. If you are buying refurbished, check the warranty length and battery condition; our refurbished cordless hoover guide explains what to look for.
One practical note: the V15's laser and particle sensor add complexity. Owners rarely report problems with them, but if the sensor display stops updating, cleaning the bin and filter usually resolves it. See Dyson troubleshooting.
Final recommendation
- Pick the Dyson V11 if you mainly have carpets, no long-haired pets, no allergy sufferers, and you want strong Dyson cleaning for the least money. Check price on Amazon
- Pick the Dyson V15 Detect if you have hard floors, long hair in the house, pets, or allergies, or you will simply clean more thoroughly when you can see the dust. Check price on Amazon

FAQs
Is the laser on the V15 a gimmick?
On hard floors, no: it makes fine dust and hair visible at a low angle in a way room lighting does not. On carpet it adds very little.
Can I add the laser head to a V11?
Dyson sells laser and Fluffy heads as accessories, and many owners report they fit V11s via the shared click-in connection. Check compatibility on Dyson's site before buying, as head and motor combinations vary.
Is the V15 heavier than the V11?
Not meaningfully. Both weigh around 3kg in stick form.
Which is better for pet hair?
The V15, thanks to the anti-tangle Motorbar and Hair Screw tool. See our pet hair picks for other options.
Is the V11 still on sale in 2026?
Availability varies by bundle and retailer. The V11 has been gradually replaced in Dyson's own range but remains common at retailers and on Dyson's outlet. Check the exact bundle before buying.
Do the V11 and V15 use the same batteries?
Current V11 and V15 models both use click-in batteries, but check the part number before buying a spare, as Dyson's batteries are model-specific.
