Unverified85% confidenceDecision RuleTime unknown
判断实际清洗力要看压力×流量的组合，而非单看bar数：流量低于300L/h时即使压力高，冲刷面积小、耗时长；洗车推荐流量≥400L/h

Unverified家用清洗车、地面选压力100-130bar即可，流量需≥360L/h才能保证冲洗效率；压力高但流量低（<300L/h）实际清洗速度反而慢90% similarUnverified流量（L/h或L/min）比水压更影响实际清洗效率，同压力下流量400L/h的机器冲刷面积和速度明显优于300L/h；清洗大面积地面优先看流量84% similarUnverified流量（L/h）比峰值压力更影响实际清洗效率，家用建议选流量≥400L/h，仅看bar数忽略流量会导致'压力大但冲不干净'的错觉83% similarUnverified家用洗车、洗地清洁选择额定压力100-120bar、流量≥350L/h的机型即可满足绝大多数需求，超过140bar的高压对家用场景是过剩配置且更易损伤车漆和瓷砖缝隙82% similarUnverified洗车用途选择额定压力7-10MPa即可满足去除泥污需求；追求瞬时峰值压力超过12MPa可能损伤车漆清漆层，需搭配泡沫壶降低直冲伤害81% similar
