（1）對洗車機器各部(bu)(bu)分性(xing)能穩(wen)定性(xing)進行(xing)考察洗車機器由(you)電(dian)(dian)(dian)控部(bu)(bu)分、電(dian)(dian)(dian)動(dong)部(bu)(bu)分、機械(xie)部(bu)(bu)分、扭動(dong)部(bu)(bu)分、電(dian)(dian)(dian)傳感器和主(zhu)結構(gou)框架等組成。在選購時(shi)首先要看電(dian)(dian)(dian)控元(yuan)氣(qi)件(jian)(jian)的(de)安(an)全保護(hu)是(shi)否(fou)全面即漏電(dian)(dian)(dian)保護(hu)如(ru)(ru)何。電(dian)(dian)(dian)腦(nao)主(zhu)板的(de)元(yuan)件(jian)(jian)是(shi)采用(yong)完(wan)全進口的(de)還是(shi)國產(chan)的(de)，或(huo)是(shi)哪(na)個廠家生(sheng)產(chan)的(de)，在用(yong)戶中(zhong)口碑如(ru)(ru)何，這樣可以(yi)從中(zhong)考察部(bu)(bu)件(jian)(jian)的(de)可靠性(xing)。電(dian)(dian)(dian)動(dong)部(bu)(bu)分的(de)部(bu)(bu)件(jian)(jian)如(ru)(ru)電(dian)(dian)(dian)機、差(cha)速器以(yi)及(ji)氣(qi)動(dong)部(bu)(bu)分，如(ru)(ru)德國、日本(ben)和美(mei)國的(de)產(chan)品相對(dui)質量穩(wen)定，當(dang)然(ran)主(zhu)框架的(de)材料(liao)及(ji)是(shi)否(fou)經過(guo)防銹處理(li)也要考慮，如(ru)(ru)處理(li)不(bu)當(dang)會(hui)影(ying)響(xiang)到(dao)整體的(de)美(mei)觀(guan)及(ji)使用(yong)壽命(ming)。

（2）選好洗車機器的(de)刷(shua)毛(mao)(mao)(mao)材料(liao)(liao)至關重(zhong)要洗車(che)機的(de)刷(shua)毛(mao)(mao)(mao)材料(liao)(liao)會直接(jie)影響到洗車(che)的(de)效果，現在市(shi)場上(shang)用(yong)(yong)的(de)毛(mao)(mao)(mao)刷(shua)主要有塑料(liao)(liao)毛(mao)(mao)(mao)刷(shua)、復合(he)布(bu)(bu)刷(shua)毛(mao)(mao)(mao)和泡(pao)沫棉刷(shua)毛(mao)(mao)(mao)3種。塑料(liao)(liao)刷(shua)毛(mao)(mao)(mao)因材質(zhi)較(jiao)硬，容易(yi)傷(shang)(shang)車(che)漆(qi)，使(shi)用(yong)(yong)的(de)較(jiao)少，復合(he)布(bu)(bu)刷(shua)毛(mao)(mao)(mao)含沙量大，適合(he)在沿海地區使(shi)用(yong)(yong)；泡(pao)沫棉刷(shua)毛(mao)(mao)(mao)使(shi)用(yong)(yong)壽命較(jiao)長，不易(yi)傷(shang)(shang)車(che)漆(qi)，所以采用(yong)(yong)的(de)最為(wei)廣泛(fan)。
