Eufy robovac 11 works fine in the living room, but bumps into walls in every other room

So I got a robovac 11. It works just superb in the living room (dark laminate and coffe with milk walls) , but in the childs room it bumps into everything (white laminate and pink walls). Any ideas what can be the cause? Is it the color or the surface itself (too shiny)?

Sorry to hear that, @Ivan_Angelov! Please reach out to and the tech support staff will be happy to look into this for you. Thanks!

Also try giving the sensors on the bottom of the vacuum a clean.
