Can I use any detergent with a Kärcher Hard Floor Cleaner?
We strongly suggest only using the Kärcher floor cleaning detergents with our Hard Floor Cleaners. These have drying agents in them to enable the super-fast 2 minute drying time. They also have foam stop chemical to limit foam and streaks being left on the floor.
To add to this, we have not tested the use of external detergents being used with our Hard Floor Cleaners so we can not guarantee that there won't be complications with the machine if other detergents are used.
