The most powerful, intelligent cordless vacuum, with 240AW. A laser makes invisible dust visible on hard floors. A piezo sensor continuously sizes and counts dust particles – automatically increasing suction power when needed. LCD shows what's been sucked up in real time.

While lighting has been a feature on vacuum cleaners for many years, the Dyson V15 Detect sets itself apart using focused light - in the form of a precisely-angled laser - to detect microscopic dust particles usually invisible to the naked eye.

Our latest vacuums use adapted laser technology to reveal hidden dust[4], integrating a diode laser into the cleaner head that is precisely positioned at a 1.5 degree angle, 7.3mm off the ground to create the best contrast between dust and floor.

The screen shows the particle count, which is an accumulation of the dust picked up during a clean, and the bars on the LCD screen represents size examples of debris that could be found in your home: Greater than 10 microns – allergens and pollen. Greater than 60 microns – microscopic dust and skin flakes.

The laser head I expected to be a gimmick, but it really shows the dirt and hair on the floor. Compared to previous corded models the anti tangle head is amazing! No more cutting hair off the head! It's clean after every run.

It makes night vacuuming a thing - the darker it is, the more visible the laser. An attachment for carpet includes a cutter to slice up hair, which reduces the need to do maintenance on the head.

V15 Detect™ Which Dyson vacuum cleaner has the illumination? The Dyson Gen5™, V15 Detect™, and Dyson V12 Detect Slim™ have a illumination cleaner head.

And is showing the results in real time. Now let's see what the meaning is of each of those four bars. The yellow bar represents particles which are of the size of elegance.

The V15 Detect+ model includes all of the previously mentioned accessories, plus a low-reach adapter to help you clean under furniture. It also comes with a multi-purpose combi-crevice tool, instead of the standard crevice tool you get with the V15 Detect.

While traveling through the vacuum of space, laser beams are invisible unless shot directly into your eye. The experience you know of as vision consists of light entering your eyes and being detecting by cells on your retinas. You can't see any light that never enters your eyes.

After testing, the latest cordless vacuum from the company, the Dyson V15 Detect (available at Amazon for $677.99) , emerged as the best Dyson vacuum for its battery life, suction power, and a laser that illuminates the tiniest speck of dust.
