With new Ball technology, the DC40 houses more components inside the ball, reducing clutter around it €“ steers right up to edges and into difficult places. Weighing only 14.5 lbs, it€s lightweight and durable, engineered materials are selected for their strengths and durability. Instant release wand stretches up to 5 times in length for stairs and hard to reach places. Motorized brush bar is powered by an independent motor for better cleaning performance and has fingertip controls to instantly turn the motorized brush bar off for hard floors, delicate floors and rugs.

Washable lifetime filter captures allergens and microscopic particles such as pollen, mold and bacteria and expels cleaner air. Clear bin is made from tough polycarbonate, letting you see when it€s full and empties at the push of a button. No need to buy replacement bags, belts and filters means no extra costs and less impact on the environment.

DC40 Multi Floor comes with a combination tool that has soft bristles for gentle dusting and a stair tool for removing dirt and dust from corners and vertical edges of stairs. DC40 also includes a 6 month warranty, parts and labor guaranteed by Dyson.

Patented Dyson Technology

Dyson engineers are constantly testing and inventing, trying to find new ways to make their technology better. As they work, they file patent applications to protect their inventions from copycat manufacturers. That€s why the only place you€ll find Dyson technology is inside a Dyson machine.

New Radial Root Cyclone technology
Ordinary vacuum cleaners rely on bags to trap dust and dirt. As you use them, the tiny holes in the bag clog up with particles of dust. This restricts the flow of air, so the vacuum cleaner loses suction. Dyson vacuum cleaners don€t rely on bags to trap dust and dirt. They use cyclone technology, which spins the air at incredibly high speeds. The cyclones inside a Dyson vacuum cleaner generate centrifugal forces many thousands of times the force of gravity. Dust, dirt and pet hair are flung out of the airflow and straight into the bin. No bag. No loss of suction.

Dyson has been continually refining cyclone technology since inventing it more than 20 years ago. DC40 Multi floor has new Radial Root Cyclone technology. Reconfigured air channels and improved flow efficiency reduce turbulence and preserve air pressure, so that the inner cyclones can extract more microscopic particles. These refinements help remove more dirt, dust, allergens and pet hair for the airflow.

Ball technology to help you steer with ease
Dyson Ball upright vacuum cleaners use patented Ball technology to overcome the steering limitations of fixed wheels. They ride on a ball, which turns on the spot so you can steer with ease, changing direction with just a turn of the wrist.

The ball itself is made of glass-reinforced polypropylene- the same material used in the manufacture of car dashboards. It combines high impact strength with the resistance to distortion. The ball also holds the heaviest component, (the motor), positioned towards the base for a lower center of gravity and greater stability.

About Dyson Refurbished Vacuums

Fully Restored and Functional
Dyson refurbished vacuums have been stripped down, cleaned out, reassembled and thoroughly tested. They€re restored to a fully functional condition. In short, they are everything a Dyson machine should be- they work properly and don€t lose suction.

Dyson refurbishes vacuums that are returned to us by retailers or consumers. Refurbishing these machines, rather than disposing of them, means that the parts and materials are re-used instead of wasted.

Refurbishing the Vacuum
When a machine comes to us to be refurbished, it is first stripped down as far as necessary. Components removed from the machine that meet our high standards of quality are kept and cleaned. Most damaged or broken components are sent away for recycling. The core of the machine is thoroughly cleaned and new parts are added to replace damaged or cosmetically unacceptable parts discovered during the stripping down process.

Just like our brand new machines, the rebuilt machine then undergoes a comprehensive series of electrical and performance tests to ensure that it works as it should. For our vacuums, one of the tests carried out is a suction test. All refurbished vacuums are electrically tested in compliance with electrical and safety requirements.

6 Month Parts and Labor Warranty
One of the primary differences between a new Dyson machine and a refurbished Dyson machine is its appearance€“ a scratch here or there or a slightly clouded bin may provide a clue that it has been previously used. After it has passed all of the tests, the machine is then packaged and sent out. All Dyson refurbished vacuums come with a 6 month parts and labor warranty.
