The Kärcher SC 2 does not escape our test protocol: it too must wash the floor of our laboratory under our trained eyes. As usual, the evening before our test, we spread lipstick, oil, soda and a mixture of water and carbon black (to simulate soot).

The next morning, we fill the sled with a liter of water and wait nearly 4 min 48 s before spurting out the steam. The Kärcher becomes, by far, the slowest device of our comparative. For comparison, the Vileda Steam Plus takes less than 20 seconds to be operational.

That is ! SC 2 is now getting down to its task: to make the lab shine. We set its steam output to maximum intensity and start the test. The device is very handy, unlike the SC 3 Upright EasyFix, whose wipe clung to the floor. We go back and forth on soda and oil twice before these stains disappear. But it is a failure against the two most resistant substances. The three specks of carbon black quickly fade into large streaks; same for the lipstick. After 20 round trips, the result remains the same.

We also measured the autonomy of action with a full tank. With a minimum steam output, the Kärcher can clean for 22 minutes, against 21 minutes with a maximum steam output. This very similar time may be due to the amount of water the floor cleaner throws off. Indeed, we were surprised by the humidity, even the small puddles that the Kärcher created in its path. It is then necessary to be vigilant with fragile soils, so as not to soak them.
