How do I use a handheld steamer?

[Evvy543]

I've been giving a small handheld steam cleaner.
Do I just put water in it and steam clean for e.g a work surface? Or do I put water + detergent.
Also can I use it on clothes?

Nevermind everyone!!
It's a HANDHELD VACUUM 🙈😂

Got told it was a steamer, went to get it out to have a look and its manual was in there sayinf vacuum.

In that case, probably don't put water in it.
