Idivaysi ye-elektromagnetic esetshenziselwa ukuguqula amandla emishini abe ngamandla kagesi we-wiper motor iqhutshwa yimoto, futhi ukunyakaza kwemoto kuguqulwe kube yisikhathi sokubuyisa impahla ye-wiper ngokusebenzisa indlela yokuxhuma ye-wiper, ukuze uqaphele isenzo se-wiper. Ngokuvamile, imoto ingaxhunywa ukwenza umsebenzi we-wiper. Ngokukhetha isivinini esiphezulu nesivinini esiphansi, okwamanje kwemoto kungashintshwa, ukuze kulawulwe isivinini sezimoto bese ulawula ijubane lensimbi ye-wiper.
I-WIPER yemoto iqhutshwa yi-Wiper motor, nge-Potentiometer yokulawula ijubane lemoto yamagiya ambalwa.
Ngasekupheleni kwangemuva kwe-Wiper motor ukuhanjiswa kwamagiya amancane okuvalelwe ezindlini ezifanayo, okunciphisa ijubane lokukhipha kwijubane elidingekayo. Le divayisi yaziwa kakhulu ngokuthi umhlangano we-wiper drive. Umsetha womhlangano uxhumene nedivaysi yemishini yokuphela kwe-wiper, ebona ukujikiswa okubuyisanayo kwe-wiper ngemfoloko drive kanye nokubuya kwentwasahlobo.
