- the "pick up me" function doesn't always work well, - when I want to guide myself the S400 to clean manually certain areas of the pool, the S400 doesn't react as expected and with too much delay. I don't know if theses problems come from my phone (I tried two). Maybe should I update some firmwares.

It provides enough power for a 6 x 4m pool. Although there were periods when the 2.5-hour cycle time did not prove useful, so the drum had to be started again. He thinks a lot at the start, then he starts, but sometimes he has difficulties getting up to the side wall in the foil pool. It is not a top category, it has two big advantages, one is that its multi-layer filter basket can catch all kinds of dirt, the other is that it is a Wi-Fi device and can be started remotely if necessary.

. APPLI. MERDIQUE ET PROBLEMES POUR LA RECHARGER.....MAIS COMMENT DONC FAIRE!!!!

Does a good standard job, good interface and seamless wifi connection. Lazy in climbings walls (liners), less than 10% in my case. Seriously limited when water gets close to 10 Celsius degrees, the rubber wheels harden and spin endlessly against the wall instead of bringing the robot to a tilt. Result, no clean at all, just endless spinning against a wall. Shame.
