A strange odour is coming from the vacuum cleaner.
The smell is noticed within 3 months of its initial use.
The cleaner may emit a smell of rubber for about 3 months after its initial use. This is normal.
The dust bin is full of dust.
The dust in the bin may cause some odour. Empty the bin and clean it.
Foreign substances are on the filter.
The filter may emit an odour if it has not been cleaned for a long time. Clean the pre-filter or exhaust filter regularly.
The pre-filter or exhaust filter was assembled while damp or wet.
Wash the pre-filter or exhaust filter with running water. To avoid odour, allow the pre-filter or exhaust filter to dry completely in a well-ventilated area out of direct sunlight for at least 24 hours before reassembling.
