Kärcher SC 3 Deluxe vs Kärcher SC 2 Deluxe

Is refillable, thirty-second steam worth the price difference?

These two machines cover the same 75 m (246 ft)² per tank. Everything that separates them is about waiting.

A tick marks the better answer on that line only. Counting ticks does not decide the page — the two verdicts below do, because these machines answer different questions.

Which of the two, for which job

Buy the SC 3 Deluxe

Prefer the SC 3 Deluxe if your cleaning is opportunistic — ten minutes on a hob, a shower screen before guests. It is ready before you have found the cloth.

SC 2 Deluxe

No amazon.com listing was found for this one. We hold references for other markets but none for the United States, so it may not be buyable here — which is the first thing to weigh against anything below.

Buy the SC 2 Deluxe if you clean in planned sessions, where six minutes of heat-up is irrelevant because you were going to be there an hour anyway.

The questions we hear

Does 3.2 versus 3.5 bar matter?

No. That difference is not identifiable in use. The refilling and the heat-up time are what change the experience of owning the machine.
