I was very skeptical about robotic vacuum cleaners, I must say I am pleasantly surprised at its effectiveness, it happens everywhere, on carpet (short-haired), it does not lock, it stops before typing in furniture, virtual wall works well, the mop is not used really, because not remain damp, programming works well, I feel that it runs longer than the time announced 90 minutes, it recharges 3:00 rather than 5:00, the few dog hairs disappear !!! by cons do not leave dintérieur doormat carpet style as it semmêle slightly in if they are 'too light, programming of working time does not work or does not exist as it is indicated in the instructions. .. it's a shame, because I miss it run until the battery is empty, I expect a response from the seller about it ... I do not know what the models to over 400 but the -C good price / quality ratio, in time to see the reliability .... it comes with 3 additional brushes, mops two two and a brush to clean the filters, spare parts do me seem too expensive on the site H.Koenig. damage is no longer available for the moment ...
