The battery is a little weak, but it can be used without any problems. I have only done a simple cleaning, and I have not gotten it wet or disassembled it for cleaning as I am not a professional. (Accessories) Hose (70.5cm) x 1, Floor brush x 1, Charging stand (with charging adapter) x 1, Round brush x 1, Crevice nozzle x 1, Mini motor head x 1, Extension hose x 1 (Notes) Dedicated box and instruction manual are not included. Main unit: No noticeable scratches. Hose, floor brush, and mini motor head: Some scratches. Charging stand: Partially cracked, but there are no problems with use. The battery is a consumable item, so there is no warranty. (Operation) Charging test performed (charged until the charging lamp turns off). Floor brush attached (idle running), continuous operation: Low 43 minutes, Medium 10 minutes, High 29 seconds. The high setting turns off quickly, but it can be used normally on low and medium settings. If you are concerned, you can purchase compatible products cheaply on Amazon. The output of the charging adapter is 30.05V, which is normal. Operation test OK.
