Our verdict
The V15 Detect is the cordless vacuum that finally outclasses most corded uprights — laser-revealed dust, smart suction and the strongest motor Dyson puts in a stick. Expensive, but it's the one cordless that earns the price by being the only vacuum you'll need.
The short version
The V15 Detect is the cordless vacuum that crossed the line — for most floors, in most homes, it cleans as well as or better than a full-size plug-in. The green laser on the head literally lights up dust you couldn't see, the LCD counts what you suck up and switches to the right power mode automatically, and the suction handles pet hair, hardwood, area rugs and carpet without flinching. Add the snap-on accessories for ceiling corners, car interiors and mattresses, and one vacuum covers the whole house.

Why people love it
Light up the dust
The green laser angles light across hard floors so you can see microscopic dust the human eye misses.
Suction adjusts automatically
The piezo sensor counts particles in real time and dials power up or down based on what it finds — saving battery on clean floors and ramping for dirty ones.
Empty in one motion
Hold the bin over the trash and pull the lever — the bottom opens and the dirt drops out without you touching it.
Who it's for
- Pet households with hair everywhere

Is the Dyson V15 Detect worth the price? (Honest review)
At a price that buys two of most cordless competitors, the V15 Detect is a genuine investment — and for some households it's the wrong purchase. If you have a small apartment, hard floors only, and no pets, you don't need this much vacuum and a $200-range cordless will serve you well. Where the V15 earns its money is in larger homes, on mixed flooring, and in pet households. The combination of raw suction (Dyson's most powerful motor in the cordless line), the auto-adjusting piezo sensor, and the multiple cleaning heads tackles every surface in one tool. Many owners donate their old upright after a month with the V15.
The laser is the single feature that's surprised the most owners. It looks like a gimmick on paper, but seeing a beam of green light reveal a layer of fine dust on a floor that looked clean is what gets people to keep using the vacuum more often, and that's the most important thing a vacuum can do. The real-time particle LCD is similarly motivating — watching the count drop as you pass over an area is oddly satisfying. The price stings, but if it's the difference between vacuuming once a week and vacuuming twice, it pays for itself in floor cleanliness.
Dyson V15 Detect vs V12 Detect Slim vs V8: which cordless to buy
The V15 Detect is the full-power flagship. The V12 Detect Slim is the lighter, smaller, more maneuverable version with the same laser and LCD tech but a smaller motor and bin. The V8 is the no-laser, no-LCD older platform that Dyson still sells as the entry point. Suction goes V15 (highest) > V12 > V8. Weight goes V12 (lightest) < V15 < V8.
For pet households with multi-floor homes, the V15 is the right buy — more battery, more suction, more anti-tangle attachments. For small homes or anyone with wrist issues who wants the lightest cordless that still has the modern tech, the V12 Detect Slim is the underrated pick. For tight budgets and basic use, the V8 still vacuums well and costs a fraction of the V15. Avoid the middle V10/V11 unless on a deep sale — the V15 and V12 are the meaningfully newer platforms.
How to use the Dyson V15 to actually replace a corded vacuum
The trick to making a cordless your primary vacuum is using the right head for the surface. On hardwood, the Fluffy Optic head with the laser is dramatically better than the standard head — turn the lights down once and you'll see why. On carpet and rugs, swap to the High Torque cleaner head. For stairs, switch to handheld mode and use the Hair Screw Tool or combination tool. For ceilings, baseboards and shelves, the included extension and crevice tools turn the V15 into a long-reach duster.
Keep the wall-mounted charging dock in a high-traffic spot like a hall closet or laundry area, not buried in a basement, so it actually gets used between sessions. Empty the bin after every full session, especially with pets, and tap the filter clean once a month. For the canister itself, give it a deeper clean every few months by rinsing the filter under cold water and letting it air-dry 24 hours. Treated this way, the V15 stays at peak suction and the battery health holds up for years.

Does the Dyson V15 Detect work on carpet as well as hardwood?
Yes. The included High Torque cleaner head is built for carpet and area rugs, and the Fluffy Optic head with the green laser is built for hard floors. Both come with the V15 Detect Absolute and Complete variants. Swap heads with a button press depending on the room — there's no settings menu to dig through.
How long does the battery actually last?
Up to 60 minutes in Eco mode with a non-motorized tool, around 40 minutes with the standard cleaner head in Auto mode, and about 10–12 minutes in Boost mode for ground-in messes. Real-world cleaning of a 1,500–2,000 sq ft house typically falls well within the full charge. Some models include a swappable second battery for true unlimited cleaning.
Is the Dyson V15 worth it over the V12 or V8?
The V15 is the best cordless Dyson makes — the strongest suction, the longest runtime, the bin-clearing piezo sensor, and the laser. The V12 Detect Slim is the lighter, more maneuverable version with most of the same tech minus raw power. The V8 is the older, much cheaper budget option without the laser or LCD. For pet households, large homes or anyone replacing a corded vacuum, the V15 is the right one. For small apartments without pets, the V12 or V8 can be enough.
How often do I need to empty the bin?
Most owners empty it after every full cleaning session of a typical room or two, especially in pet households. The bin isn't enormous — it's the trade-off for the cordless stick form factor. Emptying takes about three seconds and is hygienic (the lever-release means your hand never touches the dirt).
Is the Dyson V15 Detect HEPA-filtered? Is it good for allergies?
Yes. The V15 uses a fully sealed HEPA filtration system that captures 99.99% of particles down to 0.3 microns, including dust mites, pollen and pet dander. The expelled air is cleaner than the room air going in. For households with allergies, asthma or pets, the sealed HEPA system is one of the genuine reasons to choose Dyson over cheaper cordless competitors.
Does the Dyson V15 Detect tangle with long hair?
The Hair Screw Tool (included on most V15 variants) uses a tapered anti-tangle brush specifically engineered for long human hair and pet hair — it's the single best accessory in the Dyson cordless lineup for pet households. The High Torque head also has anti-tangle features. If you have a long-haired person and a long-haired pet in the house, the Hair Screw Tool earns its keep.
