ATTENTION
In the case of heavy contamination or if parts such as
stones or splinters get into the suction head, it will need
to be cleaned. While the appliance is working, these
parts will cause a rattling noise or will block up the suc-
tion ducts, diminishing suction performance.
ATTENTION
Regularly clean the waste water tank to prevent block-
age to the separator with dust and dirt or to prevent dirt
from building up in the tank.
ATTENTION
The use of unsuitable cleaning and disinfecting agents
can damage the appliance and will void the warranty.
