Because the RAYCOP is protected by a motor overheating device, the suction will temporarily stop if:The dust box or dust box ﬁlter is clogged with house dust and/or dirt.The intake is clogged.The RAYCOP was operated continuously for more than 30 minutes, pressed too firmly against the fabric, or the motor has overheated.After pulling out the power cord, clean the dust box and check that the intake is not clogged. Wait for about 2 hours and resume using the product. (The waiting time can differ depending on the ambient temperature).If the dust box ﬁlter is clogged or suction strength decreases:Protein (such as skin ﬂakes) in house dust causes clogging. Periodically soak the ﬁlter in neutral detergent diluted with water (water to detergent ratio = 9:1) for about 5 minutes and then thoroughly wash out the ﬁlter using a brush.The dust box ﬁlter has been used for 10 minutes every day for 5 to 6 months. Cleaning the clogged ﬁlter by soaking, as described above, does not remedy the problem because the filter is torn.Replace the dust box filter with a new one from RAYCOP.由于RAYCOP受电机过热装置保护，如果出现以下情况，吸力将暂时停止：灰尘盒或灰尘盒过滤器被灰尘和/或灰尘堵塞。摄入量被堵塞。RAYCOP连续运行30分钟以上，对织物压得过紧，或电机过热。拔出电源线后，清洁灰尘盒并检查进气口是否堵塞。等待大约2小时后重新使用本产品。 （等待时间可能因环境温度而异）。如果集尘箱滤网堵塞或吸力下降：屋尘中的蛋白质（如皮肤闪光）会导致堵塞。定期将过滤器浸泡在用水稀释的中性清洁剂中（水与洗涤剂的比例为9：1）约5分钟，然后用刷子彻底清洗过滤器。灰尘盒过滤器每天使用10分钟，历时5至6个月。如上所述，通过浸泡清洗堵塞的过滤器并不能解决问题，因为过滤器被撕裂。用RAYCOP新的灰尘盒过滤器更换。
