Manufacturer's Description
Anti-jam brushbarTo prevent belt breakage, the brushbar automatically disengages and makes a ratchet noise to warn when it is obstructed.
Brush control
Dyson's brush control system allows you to switch the brushbar off when vacuuming delicate flooring, and ensures that it automatically disengages when in the upright position.
Suction release button
Engineered into the ready-to-go hose, the suction release button enables immediate suction control when vacuuming curtains or upholstery.
Dyson Dual Cyclone
The Dual Cyclone took James Dyson 15 years and 5,127 prototypes to develop, and achieves what other 'bagless' cleaners can't: constant suction room after room.
Dyson lifetime filters
Unlike other vacuum cleaners, Dyson lifetime filters mean:
No filters to buy
Constant suction and high filtration
Particles as small as cigarette smoke (0.1 micron) filtered.Ready-to-go hose
No attachments to fit. Just press the yellow catch and the hose and wand are ready to use faster than on any other upright, and will reach to the top of the average staircase.
Auto-adjusting head
Adjusts automatically to the right height setting for the floor. No need to bend down to change it. Prevents carpet wear from cleaners with manual settings if you forget to adjust the dials and switches.
B.A.F. Seal of Approval
The British Allergy Foundation aims to improve awareness of and treatment of allergies and advises people of allergy-friendly products to buy. DCO4 uses Dyson Cyclone technology to maintain constant suction and to remove even the smallest particles of dust, which is why it has been endorsed by BAF.
High efficiency airways
DCO4's constant diameter airways maximise airflow and minimise the potential for blockages by eliminating the sharp corners and bottlenecks common in other cleaners.
Edge cleaning
Suction is channelled right to the edge of the cleaner head. The brushes mounted to the outside of the cleaner can therefore flick dust directly into the airflow.
Clear binThis has 4 clear advantages: (1) You can see how well the Dyson works; (2) You can enjoy watching it; (3) You can always tell when it's full; and (4) It's easy to empty
Suction release valve
If the end of the hose is obstructed, the valve momentarily releases to prevent anyone or anything becoming helplessly attached to the cleaner.
On-board tools
The crevice, stair and brush tools are stored on the body of DCO4. Always at hand, they fit directly to both wand and hose for cleaning hard-to-reach and confined spaces eg. car.
Blockage removal port
Easy access to airways ensures that you can quickly remove any blockage.
Robust construction
The body of the Dyson DCO4 is made from ABS and polycarbonate, two of the strongest materials available.
Motorised brushbar
All Dyson uprights have a motorised brushbar. This improves pick-up on carpets by sweeping the dust and fibres trapped in the carpet pile into the constant Dyson airflow.
