Please use exclusively KÄRCHER deter-
gents and care products to carry out the re-
spective cleaning task, as these were
specifically developed for your appliance.
The use of other detergents and care prod-
ucts may lead to premature wear and can
invalidate your warranty claims. Please ob-
tain information at your local dealer or re-
quest information directly from KÄRCHER.
Notes regarding the detergent : The most
commonly use detergents can be purchased
ready to use in their detergent reservoirs with
locking lids. This will make the pesky refilling
and filling processes redundant.
