Bought the robot 3 months ago, before its LG Homebot, I was quite pleased with.
1. The app does not work well and considering how it works, I would advise against this very expensive machine. Has had several contacts with customer support, which takes about 1 v to respond and then requires a response within a few hours for the case to not be considered clear. My has not been able to start with the app so far. Maybe I have only received a B copy.
2. The sound is much higher than LGn and reminiscent of Arlanda! Fits quite often in frosted fringes, under furniture etc., but then sounds so you can find it right easily through the app, which is good.
3. Clearly cleans longer and more efficiently than LGn. Also found back to the charge. Better than LGn!
3.Support in Denmark, No good experience so far.
4. Positive that accessories type new filters are easy to order. On LGn difficult.
Well, even if everything is not perfect, it's good at cleaning. The low rating due to poor support and inoperative remote control and the very loud noise. Therefore, I would buy a cheaper machine.
