The AQUA Sprayer is used to inject water which has previously been filled into the dirty water collection container to the air flow sucked into the coarse collection section while the vacuum cleaner is in operation.
Dust, sand and other debris continuously get into this water, so inevitably some of the finest debris will end up in the AQUA spray. Thus, when the aqua filter system is in operation, dirt progressively accumulates in the AQUA sprayer.
Periodically, about once a month (after 3 or 4 cleanings), this part should be carefully removed and washed in warm water.
