Black & Decker Dustbuster Flexi

WINNER

To get the kind of performance you would expect from a household cleaner in a handheld vac, you need to pay for it, so our winner was one of the most expensive on test.

But the Dustbuster Flexi is a unique design that's somewhere between a cylinder cleaner and a handheld.

It works well, with a powerful 18-volt lithium battery providing a smooth motor.

Plus, it comes with a good range of accessories, including a long crevice tool ideal for getting down the side of seats.
