When I steam clean and vacuum floors at the same time, streaks of water are left behind. Is this normal?

The Polti Vaporetto Lecoaspira brush has been designed to wash and dry floors in one stroke. On some particularly “rough” or “uneven” floors (or where they have not been laid perfectly) you may, however, see a few streaks of water at the end. In these cases, you can clean and dry more evenly by using the supplied cloth, thereby preventing the formation of streaks.
