Problem
The vacuum cleaner
does not start when it is
switched on.
The cleaning perfor-
mance is poor.
The vacuum cleaner
keeps falling over.
Possible cause and solution
There is no battery inserted or the battery is inserted
incorrectly.
Insert the battery or check how the battery is posi-
tioned (see "Installation and connection" – "Insert-
ing the battery").
The rechargeable battery is not sufficiently charged.
Charge the battery exactly as described in these op-
erating instructions (see "Installation and connec-
tion" – "General battery information" and "Charging
the battery").
An original Miele battery has not been inserted.
Insert an original Miele AP01/AP02/AP03 lithium-
ion rechargeable battery (HX LA).
The battery was not placed in the PowerUnit when
charging it for the first time.
To activate the battery, it must be placed in the
PowerUnit the first time it is charged (see "Installa-
tion and connection" – "General battery informa-
tion" and "Charging the battery").
The charger is still plugged in.
Pull the plug out of the charging socket on the bot-
tom of the battery.
The dust container is full.
Empty and clean the dust container (see "Mainte-
nance").
The Electrobrush is dirty/blocked.
Clean the Electrobrush (see "Maintenance" –
"Cleaning the Electrobrush" and "Removing the
roller brush from the Electrobrush").
You have configured the vacuum cleaner with the
PowerUnit at the top.
Reassemble the vacuum cleaner so that it is config-
ured with the PowerUnit at the bottom (see "Instal-
lation and connection" – "Assembling the vacuum
cleaner").
