Dyson V15 Detect Review: Brilliant on Hard Floors, Beaten by Deep Carpet
One lab measured 99 percent pickup on hardwood and 49 percent on high-pile carpet with the same machine. Which of those numbers matters depends entirely on your floors.

Good · researched from 5 sources
On hard floors and low-pile carpet it is as good as cordless vacuums get, and the laser is not a gimmick. On deep carpet one lab measured it clearing under half the debris, so if your home is mostly thick rugs this is the wrong expensive vacuum.
- Buy if
- Homes that are mostly hard floors, tile or low-pile carpet · Pet owners, where all three sources rated it well · Anyone who wants to see the dust rather than trust the machine
- Skip if
- Homes dominated by thick high-pile carpet · Anyone who finds holding a trigger for twenty minutes uncomfortable · People who want to empty a bin once and be done

The number that decides this purchase
TechGearLab ran the same vacuum across three surfaces and got 99 percent pickup on hardwood, 94 percent on low-pile carpet and 49 percent on high-pile.
That is not a small spread. It is the difference between the best cordless machine in their group and one that leaves half the debris behind, and the only variable is what is on your floor.
VacuumWars reached a more flattering conclusion, scoring its carpet deep clean a perfect 100 on their scale. Both labs are credible and they load the carpet test differently, which is exactly why a single headline score is less useful than knowing which surface it was measured on.
If your home is hard floors, tile or thin carpet, this is close to as good as cordless gets. If it is deep pile throughout, spend the money somewhere else.
The laser is the surprise
Feature lights on vacuums are usually marketing. This one is not, and the unanimity across the reviews is what makes that convincing.
A green laser sits at a low angle on the hard-floor head and throws long shadows off particles that are invisible under normal light. Bob Vila's reaction after two weeks was to describe being stunned and slightly embarrassed at how much dust was there on floors that looked clean.
It only works on hard floors, and it only works in reasonably low light. Within those limits everyone who tried it kept it on.
Where it gets tiring
TechGearLab scored ease of use 7.1, their second lowest category for the machine, and the reasons are physical rather than technical.
The trigger has to be held down for the entire time you are vacuuming. On a ten minute tidy that is nothing. On a whole house it becomes the thing you notice.
Then there is the suction working against you. Both TechGearLab and VacuumWars found it hard to push across carpet at full power, because a well-sealed head pulling hard is also a head gripping the floor. Dropping a mode fixes it and costs some pickup.
And Bob Vila emptied the 0.76 litre bin three or four times getting round one house. It does not stand up on its own either, so it lives leaning against something between rooms.
What nobody disputes
Filtration. The system is sealed HEPA and TechGearLab rated the resulting air quality excellent. For an allergy household that is the second reason to buy it, after the hard floor result.
Pet hair came in at 74 percent in TechGearLab's test, which was good enough for them to keep it in third place out of twenty-one machines and hand it an Editors' Choice despite the price and the trigger.
How it scored
The overall 7.3 is the weighted average of these five criteria — we never adjust it by hand.
Cleaning performance
TechGearLab measured 99 percent on hardwood and 94 percent on low-pile carpet, then only 49 percent on high-pile. VacuumWars scored its carpet deep clean a perfect 100 on their own scale.
Value
Every source raises the price. TechGearLab still ranked it third of twenty-one and gave it an Editors' Choice, so the performance is real, just expensive.
Build quality
No durability failures reported across the three reviews. Bob Vila's practical complaint is that it will not stand up on its own and has to lean somewhere.
Ease of use
TechGearLab scored ease of use 7.1 and flagged trigger fatigue from having to hold it on. Both they and VacuumWars found it hard to push on carpet at full power.
Filtration and dust detection
Sealed HEPA filtration, and the green laser head convinced every reviewer. Bob Vila described being embarrassed by how much dust it revealed.
Pros and cons
What we liked
- TechGearLab measured 99 percent debris pickup on hardwood, the best in their group
- The laser head genuinely shows dust you cannot otherwise see, which all three sources confirmed
- Sealed HEPA filtration that TechGearLab rated excellent for air quality
- Ranked third of twenty-one cordless vacuums by TechGearLab, with an Editors' Choice
What we didn’t
- TechGearLab measured only 49 percent pickup on high-pile carpet
- The trigger must be held down the whole time, which TechGearLab found tiring
- Suction is strong enough that both TechGearLab and VacuumWars found it hard to push on carpet
- Bob Vila emptied the small bin three or four times cleaning one house
- It will not stand up on its own
- Runtime claims and measurements vary widely across sources

How we researched this
We have not had this unit on the bench. This review synthesises the manufacturer’s published specifications, independent measurements and owner reports listed below. Every figure on this page comes from one of those sources rather than our own measurement.

sources reviewed
TechGearLab and VacuumWars both run standardised debris tests and supply the pickup percentages, suction figures and noise readings, which is where the useful disagreement lives: their carpet results point in different directions because they load the test differently. Bob Vila contributed two weeks of ordinary use in a house with five pets, which is where the bin-emptying and runtime observations come from. Consumer Reports has also tested this vacuum but their review is behind a membership wall, so we have not cited results we could not read. Where the sources give different runtimes we report the mode each was measured in rather than averaging them.

The bottom line on the Dyson V15 Detect
On hard floors and low-pile carpet it is as good as cordless vacuums get, and the laser is not a gimmick. On deep carpet one lab measured it clearing under half the debris, so if your home is mostly thick rugs this is the wrong expensive vacuum.

Cleaning
Bissell CrossWave Cordless Max
Gadget Review measured suction at 0.34 kPa, which is very low. On sealed hard floors that barely matters, and on carpet it is the whole story.

Cleaning
Bissell Little Green
Blood, cat sick and coffee all came out in one session. A set-in chain oil stain lightened by about half and stayed there, which is the honest boundary of what this machine does.

Cleaning
Bissell SpotClean Pro
A mud stain came out in under a minute. Set-in coffee needed a pre-treatment and still left a mark. That boundary is the most useful thing to know about it.
