able for 50Hz and 60Hz.
The mains electrical outlet must be fitted with an appropriate cir-
cuit breaker.
Check both the vacuum cleaner and all accessories supplied with
it for any visible signs of damage before use. Do not use a damaged
vacuum cleaner or damaged accessory.
The MieleMultiFloorelectrobrush and the MieleElectro Com-
pacthandheldbrush (depending on the model) are additional motor-
driven devices designed specially for this Miele vacuum cleaner. For
safety reasons, the vacuum cleaner must not be used with a different
Miele electrobrush/handheld brush or an electrobrush/handheld

Disposing of the packaging ma-
terial
The packaging material is used for hand-
ling and protects the appliance from
transport damage. The packaging ma-
terial used is selected from materials
which are environmentally friendly for
disposal and can generally be recycled.
Recycling the packaging material re-
duces the use of raw materials. Use ma-
terial-specific collection points for valu-
able materials and take advantage of re-
turn options.
We recommend you keep the packaging
material for transport purposes.
Disposing of your old appliance
Before disposing of your old appliance,
remove the fine dust filter and dispose
of it with your household waste.
Electrical and electronic appliances con-
tain many valuable materials. They also
contain certain materials, compounds,
and components which were essential
for their correct functioning and safety.
These could be hazardous to human
health and to the environment if dis-
posed of with household waste or if
handled incorrectly. Please do not,
therefore, dispose of your old appliance
with your household waste.
Please dispose of it at your local com-
munity waste collection/recycling
centre for electrical and electronic appli-
ances, or contact Miele. You should re-
move any old batteries which are not
securely enclosed by the appliance.
These must be taken to a suitable col-
lection point where they can be handed
in free of charge. Please ensure that
your old appliance poses no risk to chil-
dren while being stored for disposal.
Sustainability and environmental protection
15
Disposing of old batteries and
rechargeable batteries
In many cases, electrical and electronic
appliances contain batteries and re-
chargeable batteries which must not be
disposed of with household waste after
use. You should remove any removable
batteries or rechargeable batteries and
dispose of them immediately in a suit-
able recycling box for batteries. Insulate
the metal contacts with adhesive tape
to prevent short circuits.
Batteries and rechargeable bat-
teries contain substances which can
be harmful to human health and the
environment and should be kept out
of the reach of children. Even flat bat-
teries can still be dangerous. If you
suspect a child has swallowed a bat-
tery, seek medical advice immedi-
ately.
The labeling on the battery and re-
chargeable battery will provide further
information. A crossed out bin means
that the battery or rechargeable battery
must on no account be disposed of with
your household waste. We are also re-
quired to inform you that a crossed out
bin, which also has one or more chem-
ical symbols below it, indicates that the
battery or rechargeable battery contains
lead (Pb), cadmium (Cd) and/or mercury
(Hg).
3E&G+J
Old batteries and rechargeable batteries
contain important raw materials which
can be recycled. Disposing of batteries
and rechargeable batteries separately
makes them easier to handle and re-
cycle.

General battery information
The rechargeable battery is supplied not
fully charged.
Charge the battery completely before
using it for the first time. Allow approx-
imately 3.5hours for this.
Once the battery is fully charged, the
battery charging state indicator at the
top of the PowerUnit switches off to
conserve energy.
The maximum charging capacity is
only achieved once the battery has
been charged and run down approx.
five times.
A full charge provides enough power for
17minutes if the vacuum cleaner is used
in its fully assembled state.
However, if you use the PowerUnit solo
(see “Operation” – “Using the
PowerUnit solo”), you can vacuum for
up to 55minutes at a time.
The running time depends on the se-
lected power level, the flooring and
how the vacuum cleaner is used, as
well as on the degree of soiling of the
filter system.

Risk of damage caused by incor-
rect cleaning.
The fine dust filter can become dam-
aged and be less effective as a result.
Do not clean the fine dust filter with
water and avoid cleaning the inside.
Do not use pointed or sharp-edged
objects to clean the filter. Do not
brush the fine dust filter (not even
with the cleaning tool supplied).
Press both release buttons at the side
of the fine dust filter lid and remove
the fine dust filter by pulling it up-
wards.
Hold the fine dust filter over a bin.
Take hold of the black section of the
fine dust filter underneath the screw
cap and turn the screw cap 10times
through 180°.
When turning the cap, you will hear a
noise, which is a normal part of how the
ComfortClean self-cleaning function
works.
Empty the fine dust filter by carefully
tapping the lower edge.
Turn the fine dust filter slightly while
you do this to free the dirt from all of
the crevices.
Refit the cleaned fine dust filter into
the PowerUnit, making sure it clicks
into position.
To continue achieving the best pos-
sible cleaning results, replace the fine
dust filter (HX-FDF20) with a new one
after approx. 3years.
