Inner cylinder filter
Move the inner cylinder tip in the direction of the arrow and wash with water.
Note
Gently remove any attached dust and debris from the filters before washing them with water.
Drain the water attached to the inner cylinder filter thoroughly after washing.
Do not shake the dust case hard while the dust case lid is open.
Doing so may result in damage.
3
Air dry the filter.
After washing the filter with water, allow it to thoroughly air dry in the shade before you reassemble it.
Do not use it without drying. Doing so might clog the filters soon and cause weak suction power or abnormal
odor. (P.E-26)
Also, do not dry it with hot air such as that from a hair dryer.
Doing so might cause a performance degrade, damage, or deformation.
4
Attach the inner cylinder filter. (P.E-19)
Risk of damage to the vacuum cleaner
Attach the dust case and filters before operation.
CAUTION
If any dust and debris enters the motor, the filter inside the vacuum cleaner might be clogged
and strange sounds might come from the vacuum cleaner.
In this case, please consult a Hitachi authorized service agent.
If the suction power is weak even after washing the filters with water, the clean filter, sponge filter, etc.
Note
might be worn.
To request replacement, please contact a Hitachi authorized service agent.

running water.
Dust case lid
Cleaning the power head
Perform maintenance when suction power is weak or when dirt becomes a concern.
We recommend periodic maintenance (about once a month).
Dust and debris stuck to the safety switch, rotary brush, brushes, wheels, air inlet, and rotating sections might
cause damage to the floor, reductions in suction power, or malfunctions.
Using the vacuum cleaner while there is dust or lint tangled around the rotary brush or its axle may lead to a malfunction or failure.
CAUTION
Remove attached dust and debris
Use the two-way crevice nozzle or a similar tool to remove any attached dust.

Remove dust and

the rotary brush by
using scissors or
other tools.
Risk of malfunction or damage to the floor
If dust and debris get tangled in the wheels, the wheels cannot rotate, which might cause
malfunction, wear, or floor damage.
After extended use, the brushes, wheels, and rotary brush might wear down.
Using the power head while they are worn out might damage the floor.
You cannot replace the brushes or wheels by yourself. Please contact a Hitachi authorized
service agent to have the brushes, wheels, and rotary brush replaced as a set.
The rotary brush can be purchased as a replacement part. (P.E-30)
