Your floors may look clean, but that's only half the story. This Dyson V15 Detect Absolute's Fluffy Optic cleaner head lights up hidden dust and dirt on your hard floors so nothing gets missed. With up to 60 minutes of run time on a single charge, you can blitz the whole house in one go without being tethered to a plug socket. Its 5-stage filtration system traps up to 99.99% of particles as small as 0.3 microns. And the piezo sensor counts and measures the dirt as you clean, so you'll see the proof of the deep cleaning on the LCD display.
