Hunhu hwemvura huchakanganisa muchina wekupisa mvura unotonhodza muchina wekuisa chiratidzo chelaser wemidziyo yedhijitari. Kana hunhu hwemvura husina kunaka uye huzere netsvina, zvinogona kukonzera kuvharika izvo zvinokanganisa mashandiro ekutonhodza kwemuchina wekupisa mvura. Zvinokurudzirwa kushandisa mvura yakacheneswa kana mvura yakachena yakasanganiswa semvura inotenderera kudzivirira kuvharika.
