Debris illumination

The V15’s green laser fluffy head is widely praised for revealing dust and hair that other vacuums leave unseen, helping users spot exactly where more cleaning is needed on hard floors.

The laser fluffy head effectively highlights dust and crumbs on hard floors, making hidden debris easier to see while cleaning.

The V12’s laser cleaner head shines a green beam across hard floors to reveal dust and pet hair that would otherwise be hard to see, helping users target dirt more precisely.

The Outsize+ includes Dyson’s laser slim fluffy head, whose green beam highlights fine dust on hard floors so you can see where more cleaning is needed even in larger rooms.

Laser illumination along the cleaner head highlights fine dust on floors, helping users see what they are picking up and making cleaning passes feel more thorough.

The Fluffy Optic green laser illumination is one of the most consistently praised features, with reviewers noting it reveals dust better than standard LEDs and can make floors look cleaner than expected. Some warn it can be obsessive-inducing for detail-focused cleaners because it highlights so much fine debris.

Dyson’s Fluffy Optic-style laser head on the Gen5 Detect is repeatedly described as extremely bright and effective at revealing otherwise invisible dust (often even in well-lit rooms), encouraging more thorough cleaning and sometimes making users realize their floors were dirtier than expected.

At least one review notes LED lighting on the floor nozzle in the Combo Complete configuration, helping visibility for dust under furniture. This benefit applies primarily to the stick/handheld floor head rather than the robot itself.

Blue illumination/laser-style dust detection is helpful for spotting dirt, especially in dim light, but it’s often considered less effective than Dyson’s green laser and some reviewers dislike that only one main head has a light/detection feature.

A sensor light on the powerhead turns on when it detects dirt, giving visual feedback so you can see when an area still needs more passes.

The V11 Animal generally lacks laser or dust-illumination features found on Dyson Detect models or some newer floorheads, so visibility aids are limited to ambient light.
