A Dyson vacuum with a green laser makes vacuuming easier. Thanks to the laser, you can clearly see dirt and dust. That way, you know for sure you vacuum thoroughly. You can find this laser on the Dyson V12, V15, and Gen5. Use the included fluffy brush for hard floors. The green laser illuminates the floor in a 1.5-degree angle and 7.3mm above the floor. This way, dust particles are visible up to 0.01mm.
