Chairs with legs made of a bent pipe in the form of an inverted letter P are like death for him - we have 6 of them around the table - all the time he fornicates and gets stuck in them. Moves the hull halfway - hangs - rolls back - changes the angle of attack - moves halfway again - hangs - rolls back - attacks again. Naturally, while losing charge. Having gored, he will squeal to clear the way for him. st, If you saved him, he will try to clean here again and again until he is discharged and leaves for the base to recharge. He'll be back in three hours, and. That's right, it will start from the same place, it will again try to move these legs, get stuck, fornicate in them, lose charge . And if you are not at home, and you did not save him, then food will get stuck, discharged, and, you, when you return, carry it with your hands to the base. And then . Well, you understand, again, all over again. The problem is solved only by raising the chairs. I need cleaning every day - and every day they need to be raised / lowered. In search of a solution to this problem, I tried to change the firmware for the robot, but there are no new firmware for it. The result of three months of use: infuriates! . If this is the best model on the market, then what are all the others!
