Vacuum umukanda wumye ni ibikoresho byumye kandi bisohora ibikoresho byumye. Ibicuruzwa byamazi bigezwa mumubiri wumye na pompe yanduye, bikwirakwizwa ku mukandara hakoreshejwe ibikoresho. Munsi ya vacuum, ingingo itetse y'amazi iramanurwa; amazi mu bikoresho byamazi arahumuka. Umukandara ugenda hejuru yamasahani ashyushye. Amazi, amazi ashyushye, amavuta ashyushye arashobora gukoreshwa nkibikoresho byo gushyushya. Hamwe no kugenda kwimikandara, ibicuruzwa binyura mubitangira guhinduka, gukama, gukonja kugeza gusohora amaherezo. Ubushyuhe buragabanuka muriyi nzira, kandi burashobora guhinduka kubicuruzwa bitandukanye. Imashini idasanzwe ya vacuum ifite ibikoresho byo gusohora kugirango itange ibicuruzwa bitandukanye byanyuma. Ifu yumye cyangwa granule ibicuruzwa birashobora guhita bipakirwa cyangwa bigakomeza inzira ikurikira.
