In the years since Dyson released its first vacuum cleaner in the early 1990s, the company has had a lot of time to perfect its cyclone machines — and it's come a long way, as evidenced by the DC40 Allergy.


Like pretty much anything that comes out of Dyson, the upright DC40 is a futuristic-looking beast of a machine. Naturally, it sports the clear dust chamber that Dyson pioneered, with colour highlights in red, gunmetal grey and metallic blue — resembling, for all the world, some kind of homage to the art of house cleaning.

The hero feature, according to Dyson, is the massive ball above the cleaner's head, which allows it to rotate in difficult directions to clean hard-to-reach areas.

The box also comes with a selection of heads that attach to the hose, which is tucked away in the cleaner's handle for an alternative to the ball head.

Putting the machine together wasn't difficult, but there are a lot of pieces involved — you will find that you probably need to use the instruction manual initially.


If you're used to a 15-year-old Electrolux dinosaur that your mum picked up for you from Godfrey's, then a Dyson vacuum cleaner is a bit of a culture shock. For starters, the DC40 is a lot heavier than it looks — so the handle on the cyclone chamber came in handy when it came to hauling it from room to room when using the hose.

As it turns out, the ball does allow the head a good degree of manoeuvrability, which is great for getting into poky, out-of-the-way corners, and the suction is strong and steady enough for picking up all but the most stuffed-into-the-skirting dirt.
