ʻO ka hiʻohiʻona o kahi pulupulu wai DC brushless ʻaʻole ia he mau pulupulu uila a hoʻohana i nā mea uila e hoʻoulu ai i ka commutation, me ke ola lawelawe lōʻihi a hiki i 200000-30000 hola.He haʻahaʻa haʻahaʻa a ua hoʻopaʻa paʻa ʻia, kūpono ia no ka hoʻohana ʻana ma ke ʻano he pamu submersible me ka hoʻohana haʻahaʻa haʻahaʻa.Hoʻohana ka paila wai kaʻa uila i ka uila.Ke hoʻohuli ʻia ka mīkini, pau nā pulupulu.Ma hope o ka holo mau ʻana ma kahi o 2000 mau hola, e pau nā pulupulu, e alakaʻi ana i ka hana paʻa ʻole.ʻO ka hiʻohiʻona o ka pauma wai kaʻa kaʻa kaʻa kona ola pōkole.ʻO ka leo kiʻekiʻe, maʻalahi e hoʻohaumia i ka toner, a me ka hana ʻino ʻole o ka wai.

ʻAʻole like me nā ʻume wai mīkini kuʻuna, ʻo ke koena ikaika o nā ʻōpala wai uila uila e loaʻa nui ʻia ma o nā ʻōnaehana mana uila.E hana ka ʻōnaehana i ka nānā ponoʻī ma mua o ka holo ʻana o ka mīkini pahū wai e nānā i ke koena ikaika o ka rotor kaʻa.Inā ʻike ʻia ka imbalance, e hoʻokō ka ʻōnaehana i ka mana adaptive ma o ka wikiwiki a me ka deceleration a i ʻole ka hoʻoponopono ʻana i ka mana mana e loaʻa ai ke koena ikaika o ka mīkini pahū.
