Good evening I am looking for a robot hoover with a HEPA filter, which above all picks up dust reliably, preferably daily with a system and display or control whether it has actually cleaned everywhere or not. I would still rather pick up dust in addition, but that's not my focus, which is why I don't have to buy the latest model. Because of bad experiences with Romba (a few years ago) I came across the Roborok S5 Max, currently my favourite because of the good reviews. My questions: 1. can it bypass slats of approx. 2 cm height without getting stuck all the time? Concerns our dining chairs with metal slats on the floor. 2. what exactly is the difference to the S6 or S6 pure? Similar in price... 3. what are the disadvantages of the Roborock S5 Max from your experience? Thank you very much in advance.
