Warranty and post-warranty service
Unless you plan to replace the robot vacuum cleaner the first time it breaks down, make sure it's under warranty. However, even this point is not enough. Not every store will help you sort out the problem. So check whether there are official service centers in Russia and whether the seller correctly filled out the warranty card. Keep your purchase documents for the duration of the warranty. Without them, the cost of repairing the vacuum cleaner will not be reimbursed.
