Bought in August for 10+tr. Then they thought of lowering the price. Pretty stupid and ill-conceived vacuum cleaner for its price. Much less trouble (more precisely, none) is given to me by a regular robot vacuum cleaner from Tefal for 5 thousand, which, although it randomly drives, does not get stuck at every junction and calmly drives into the thresholds + reacts to the remote control regardless of its mood. I do not advise, it hurts a lot of trouble
