Dyson is one of the most respected appliance brands around, and has a reputation for invention. In my role as a TechRadar Homes Editor, I've had a chance to try out almost all of this brand's gadgets and appliances (as well as plenty of competitor products, for added context). I'm consistently impressed with Dyson's creativity and innovation... but not all of its inventions are quite as good as others.

Below, I've listed Dyson's big innovations, ranked from best to worst. To narrow things down a bit, I've focused on the brand's vacuum cleaners and haircare gadgets, though, of course, it also has significant stakes in the air purifier and fan markets. Read on for the Dyson features that truly blew me away, and those that turned out to be downgrades in disguise.

#1. A teeny tiny motor

Any handheld gadget typically benefits from being as compact and light as possible. For its Supersonic r hair dryer, Dyson shrunk the motor right down and put it in an incredibly compact shell. It looks weird, but it's a dream to use, with the pipe-like shape directing air with precision – plus, it blasts out air with serious force for such a small gadget.

Perhaps even more impressive is the new Dyson PencilVac. This is a cordless stick vacuum, except all the internal mechanics have been shrunk down and tucked into the handle, which is 1.5 inches / under 4cm in diameter.

It looks like a broom handle, except inside there's a tiny little motor, alongside filters, a battery, and even a dust cup. It almost defies belief. I've been busy testing this gadget at home, and it's ultra-nimble and light.

#2. Lasers on vacuums

Want to be disgusted by exactly how dusty your floors are? Now you can! Dyson was the brand that first put dirt-illuminating laser headlamps on its vacuum floorheads. They're ultra-bright and positioned at precisely the right angle to cast big shadows on the tiniest particles and finest hairs on your hard flooring.

They're genuinely useful in making sure you get every last speck of dust cleared away. They're also just generally really satisfying to use and helpful in highlighting (literally) the dirt-hotspots that are getting neglected.
