Homes & Gardens Verdict

Scary, wild, unbelievable, but in all the right ways. The ability to see what the naked eye can't detect, game-changing, and a scientific Piezo sensor giving a physical number to what's being collected, perhaps a little unsettling. But, if you're a person who loves data or looking to accept the cold, hard truth to what's on your floors, you will seriously be blown away.

Some choose to lead their lives according to the ideal of ignorance is bliss. If they can't see it, it must be clean, but for the other half of the population, you'll want to consider the Dyson V15 Detect cordless vacuum. Dyson's floorcare innovation brings never-before-seen technology to its floorcare lineup of the best Dyson vacuums, with the addition of a built-in green laser that illuminates dust particles invisible to the eye on hard floors and a scientific Piezo sensor that counts dust particles down to a microscopic 10 microns. into its signature Fluffy cleaner head for physical proof of a deep and effective clean.

Is it gimmicky to know the precise number of particles on your floors? Perhaps. Is it reassuring to know your floors are cleaner than they were before? Absolutely. 

I've been using the Dyson regularly since it launched in March 2021, and it remains one of my favorite vacuums to date.  Not only are my floors visibly cleaner, but I also enjoy slinging the V15 Detect around my hardwoods to spot-check every last surface, with a generous long-lasting battery that gets me through all my cleaning routines. 

The Dyson V15 has truly been put to the test, and now, I'm sharing my thoughts and experiences with this premium cordless vacuum. By the time you're finished reading, you'll see why it's one of the best cordless vacuums we've seen.

Who will love the Dyson V15 Detect?

Dyson fans looking for the next best thing in floor care will want to run toward the new Dyson V15 Detect.

But specifically, the V15 Detect is specifically for those who love physical reassurance that their home is getting clean. According to Dyson, their goal was to provide owners with a scientifically proven clean that you can actually SEE and give assurance that any missed spots are revealed while cutting down the time you’d spend going over the same spot that might actually be totally clean! 

To get the most out of the V15 Detect's laser technology, we think the Dyson V15 Detect is ideal for homes with a lot of hard floors, as while the vacuum takes carpet dust to task, the green laser only works on hard floors. However, the built-in Piezo sensor still displays data on both hard floors and carpets.

Dyson V15 Detect: design

The Dyson V15 Detect follows similar body stylings of pre-existing Dyson stick vacuums. 

The motor, .2 gallon dustbin, and battery are located at the top of the vacuum, and the V15 continues to make use of Dyson's signature trigger operation. Each accessory piece clicks in and out with ease. 

The major changes, you'll see under the hood, with the addition of a Piezo sensor, and a diode laser added to the Fluffy floorhead. 

The Dyson V15's Dyson Hyperdymium motor spins at up to 125,000rpm and generates 230 air watts of suction, which is 24% more suction power than the V11 range. The  5-stage filtration captures 99.99% of dust particles down to 0.3 microns for a powerful deep clean. 

The Dyson V15 Detect is actually very automatic, with very few features that you have to decide between. Just press the trigger ( there's no continuous mode) and if you want the vacuum to work harder, you have the option to also go into Boost mode, but it shortens the battery time. We found that Eco and Auto modes were plenty sufficient

Dyson V15 Detect: features and functions

Laser Dust Detection
Most vacuums have LED floor lights to light up the path in front of you, but the V15 Detect introduces a green laser onto its Fluffy cleaner head that makes hidden dust visible on hard floors. The idea came about when a Dyson Engineer noticed that airborne particles in their home glistened in the sun. They began to research how they could take this notion and apply it to the fine dust we cannot see in our home. It was determined that the color green provides the best contrast to what the naked eye can't see and is precisely positioned at a 1.5-degree angle, 7.2mm off the ground. Particles are most visible in low-lit areas, and even the dark, as bright sunlight can wash out the laser.

PIEZO Sensor
For those who want real-time proof and insights into the dirt on their floors, Dyson integrated an acoustic Piezo sensor into the design that continuously sizes and counts dust particles and shows how much has been picked up in a graph on the LCD screen. Essentially, once you notice the numbers start to slow, you can assume that the Dyson has suctioned everything there is to pick up.  Plus it will automatically increase suction power across different floor types based on the amount of dust and other particles present on the surface.

So, how does this work? Carbon fiber filaments in the cleaner head pick up microscopic particles which are sized and counted up to 15,000 times a second. When dust enters the vacuum and hits the acoustic piezo sensor, the tiny vibrations are converted to electrical signals. 

The Piezo sensor counts pieces smaller than 10 µm, like allergens and pollens, less than 60 µm,  particles the size of microscopic dust and skin flakes, 180 µm Particles the size of dust mites and fine sand, and 500µm particles the size of sugar and fleas. 

I personally ran into an issue where my Piezo sensor was switched off, and it's not a feature that I missed or affected the cleaning performance of my machine. Dyson was quick to remedy me with a replacement unit, but I do wish that it was something that could have been repaired without requiring an entirely new device.

Anti-Tangle Hair Tech
Keeping our pets and long-haired users in mind, Dyson has reworked how hair interacts with its technology by developing an anti-tangle conical brush bar that spirals hair off and into the bin to prevent hair wrap on the brushbar.  The tech is available on a smaller and full-size High Torque Cleanerhead, which has polycarbonate teeth that look like a comb and prevent tangling around the bristles when you are cleaning, and automatically clear hair from the brush bar. 

LCD Screen
The LCD displays will show a real-time count of the collected particles from the PIEZO sensor, a run-time countdown clock, the power mode in use, and maintenance alerts, such as when an air channel is clogged, or the bin needs emptying. 

You'll only find the best with Dyson. The V15 Detect offers Dyson’s 5-stage advanced filtration technologies, capturing 99.97% of particles as small as 0.1microns, to expel cleaner air.
