Product overview

Root cyclone technology is a unique system

that does not rely on ﬁlters or bags to separate

dirt from the air. Instead it uses powerful

centrifugal force to spin the dirt out of the air,

so there is no clogging and no loss of suction.

Combined with Dyson’s latest innovation - the

core separator - it’s more efﬁcient at

removing microscopic dust than any other

cyclonic system.

Motorised brush head

Powerful bristles remove dirt and pet

hair. Uses toothed belt that doesn’t

slip or need replacing.

(Motorhead variants only).

It uses the latest digital vacuum

technology, so it produces zero

carbon emissions. It’s also

smaller and lighter than

conventional motors and is

protected by an intergrated, on

-board self-diagnostic system.

(DDM variants only).

Trigger bin-emptying

Just push the button to empty the

bin. No need to touch the dirt.

Telescope Wrap system

Hose and wand compress and wrap for easy carrying and storage.

Root cyclone technology

Doesn’t clog and doesn’t lose suction.

Dyson core separator

Combined with Root cyclone technology for increased

cyclone efﬁciency.

Fingertip controls

Operate the machine without bending down to reach

the controls.

(RF models only).

Technical info.

Electrical safety testing

Ensure that at all times during the repair and testing of products

that customers, pets, children and you are not exposed to any

Live electrical supply.

Insulation test

The following tests must be performed

prior to and upon completion of all

repairs to Dyson ﬂoorcare products and

before any functional checks. You must

ensure that a full visual inspection

of the product is completed prior to

repair. These tests are vital to avoid any

possibility of personal injury to the end

user.

Test results

An insulation test reading of >2 MW

is acceptable.

A reading of below 2 MWis not considered

safe and further investigation, rectiﬁcation

and testing must be completed before the

product is used. The following component

must be visually inspected:

Satellite assembly antenna.•

If you cannot repair a product with an

insulation test reading of below 2MW

you must inform the customer that the

product is unsafe to use.

Please inform the customer of the

required actions to repair the product

(including the charge structure).

If the product is left un-repaired please

indicate on your paperwork/hand held

device that the product is electrically

unsafe and attach a ‘WARNING:

product electrically unsafe’ sticker in

a visable location on the product.

The Seaward Primetest 200 (or equivalent)

should be used to test the electrical

insulation of a Class 11 appliance; it

indicates any electrical leakage.

Insulation test points:

Test the ﬁve screws highlighted in the

post ﬁlter housing.

DDM on-board diagnostics

DDM variants of DC22 also include the following on-board diagnostics:

Green light: machine is healthy

Red light: machine is blocked. The machine should be

unplugged from the electrical outlet and checked for blockages.

Once the blockage is cleared the machine should be plugged

into the electrical outlet. The ON/OFF button will continue to

illuminate red. Once the machine is turned on the ON/OFF

button will change to green to indicate it is healthy.

Flashing Red/Green light: pre-ﬁlter is missing. If missing ﬁt a

ﬁlter. If the pre-ﬁlter was present check the actuation of the pre-

ﬁlter microswitch when locating the pre-ﬁlter into the chassis. If you

can’t hear an audible click when locating the pre-ﬁlter replace the

DDM assembly. If an audible click is heard check the ribbon cable

is attached to point J2 on the satellite assembly. If the problem is

still present replace the satellite assembly.

No light: LED failure. Replace the switch/PCB assembly and

retest. If there is no light after replacing the switch/PCB assembly

replace the satellite assembly and retest. If there is no light after

replacing the satellite assembly replace the DDM assembly.

Flashing Red light: brushbar jammed (Motorhead model only).

The machine should be unplugged from the electrical outlet

and the motorhead ﬂoor tool checked for blockages. Once the

blockage is cleared the machine should be plugged into the

electrical outlet. The ON/OFF button will continue to ﬂash red.

Once the machine is turned on the ON/OFF button will change

to green to indicate it is healthy.
