Cleaning the Washable Filters
To maintain optimum cleaning performance regularly remove the filters and tap against the side
of the bin to release dust. The filters should be washed by hand in warm water when the filter has
reached an excessive dust level. Do not use hot water or detergents.
IMPORTANT: All bagless cleaners require regular filter cleaning. Failure to clean your filters may
result in air blockage, overheating and product failure. This may invalidate your guarantee.
*Certain models only
IMPORTANT: Always ensure the filters are fully dry before use. Do not use the product without
the filter fitted.
UV-C Lamp Cleaning
To remove the UV-C Lamp cover plate, remove the 2 screws [12] and remove the UV-C cover
plate. Use a dry soft cloth or cotton swab to gently wipe clean the lamp [12].
After cleaning replace the UV-C Lamp cover plate and secure the cover in place using the 2
screws.
IMPORTANT:
The penetrability of the UV-C lamp is weak, any paper, lead, glass or plastic may greatly reduce
the intensity of UV-C irradiation. Any dust or oil on the UV-C lamp will directly affect the
penetrability. The UV-C lamp should be cleaned regularly.
Do not touch the UV-C lamp with your bare finger, the stain you leave on it will affect the
penetration of sterilization light.
Regularly check and maintain the filters.
If the appliance will not be used for a long time, please store the appliance in a cool dry place, do
