Idivayisi ehlanganisa ukuguquguquka okuguquguqukayo kwesithuthuthu solwandle nemisebenzi yobungcweti yokususa iqhwa. Ingakwazi ukuzulazula ezindaweni eziyinkimbinkimbi njengesithuthuthu esingekho emgwaqeni kuyilapho isusa kahle iqhwa, ukulinganisa ukuhamba namandla okususa iqhwa.

Yakhelwe endaweni yesilayishi, lesi sisetshenziswa esinzima sokususa iqhwa singakhweza kalula okunamathiselwe okuhlukahlukene okuhlanganisa abajikijeli beqhwa, amarola eqhwa, neziphepheli zeqhwa. Ihlanganisa umthamo oqinile wokuthwala umthwalo nokuphuma kwamandla aphezulu, isingatha kahle izimo zokunqwabelana kweqhwa, okuyenza ibe yisixazululo esiyinhloko sokususwa kweqhwa elikhulu. Inikwa amandla yizinjini zikadizili, iletha ukusebenza okumangazayo.
