Excellent cleaning power ; Advanced air filtration ; That laser REALLY shows up dirt ; Light weight ; Battery-preserving auto mode

'Dust detect' feature seems a little pointless

It's not a huge step up from the V11 but, okay, Dyson V15 Detect now officially supplants it as the world's best cordless vac. The previously invisible dirt revealed by its laser is truly grotesque, but there's no faulting its light weight, impressive...

Very powerful suction ; Auto suction mode is useful ; Laser highlights dust on hard floors ; Well-designed and high quality

Premium pricing ; Some features perhaps superfluous ; Long recharge times

It's no longer the newest model out, but the Dyson V15 Detect is still a superb cordless vacuum with a spree of innovative features. It debuted laser light on the Fluffy Optic tool to illuminate dirt on the floor, showed us an ingenious way to measure...

The best cordless cleaning around ; Anti-tangle hair screw is brilliant ; Laser Detect works well in darker spaces ; Excellent accessories ; Wall-mount included

So very costly ; Laser Detect can seem gimmicky ; V10/V11 almost as good for less money

Outstanding cleaning ; Replaceable battery ; Laser lets you see dirt

Expensive ; Short battery life for carpets ; Full charge takes 4.5 hours

Highly impressive cleaning power and versatile enough to clean hard floors, carpets, stairs and even your car. The V15 Detect's laser shows you where dirt is and the brushes don't get tangled up with hair.

Excellent ergonomic design ; Easy plug-and-play attachments and conversion from floor to hand-vac use ; Remarkable suction power ; Fun LCD display and green laser floor illuminator ; Point-and-shoot dustbin emptier keeps your hands clean

Power heads can damage hand-woven rugs ; No rug-cleaning attachment that is not equipped with a beater bar ; Steep price tag

My seasoned, Iranian-born almost had a heart attack when I bragged about testing a powerful new Dyson vac with an always-on motorized roller head. “Stop that!” he declared. “It’s pulling out threads, destroying your rugs! Only use a vacuum cleaner with...

Cordless. Easy to use. Lots of useful accessories.

Too heavy! Cleaning the dust bin could have been easier
