Izihlukanisi zangaphambili zenzelwe ukunciphisa kakhulu inani lothuli olufinyelela isicoci sakho se-vacuum, ukusivumela ukuthi sisebenze ngokusebenza okuphezulu kakhulu isikhathi eside. Ngothuli oluncane oluvale izihlungi ze-vacuum, ukugeleza komoya kuhlala kungavimbekile, kuqinisekisa amandla afanele okumunca kuyo yonke inqubo yokuhlanza.
Ngokunciphisa umthwalo wokusebenza kuzihlungi ze-vacuum yakho, izihlukanisi zangaphambili zandisa ngempumelelo impilo yesicoci sakho se-vacuum. Lokhu kusho izinkinga ezimbalwa zokunakekela kanye nohambo olumbalwa oluya esitolo ukuze uthole izihlungi ezishintshayo. Tshala imali kusihlukanisi sangaphambili namuhla futhi ujabulele isixazululo esihlala isikhathi eside, esithembeke kakhudlwana.
