After 7 months of use, the vacuum cleaner began to turn off somewhere when the balance was less than 30% of the charge. After 8 months, the ill-fated Error 7. This is a battery error, the warranty for which is only 6 months (1 year warranty does not cover the battery). Then you can either buy a new one for 7000, which will again live for another 6 months, or try to restore the existing one in third-party offices at your own peril and risk.
