Regarding the docking station for collecting garbage, we immediately bought it, but it can work without it, you will need to shake off the garbage from the dust collector yourself. Different pros: I like how he moves during the cleaning process, i. E. these are not just chaotic movements, but a well-thought-out cleaning plan. First, he collects light debris, if something is not collected, he returns and vacuums again. I built a map of the house from the second run, then only clarifications were made, regarding restricted areas, etc. We have enough charge for the 2nd + kitchen from the hallway. Got cons: Everything suits, if there were difficulties with the settings, we eliminated them as we used them.
