Pay more don't buy
Was impressed when opened, first sweep the unit gets stuck in any tight space or runs too hard over an object and gets stuck. The wheels squeak very loudly and constantly. I have a large rectangular living room, connecting kitchen and connecting dinning room, even if the base is in clear sight of the vacuum and I hit 'Dock' on the mobile app it just keeps sweeping. If I 'drive' it manually to about 2-3ft in front of the dock it will attempt and reattempt docking until the battery dies (never docks). The dock itself I believe is to blame as the two small metal squares never line up, even manually placing it on the dock it takes several tries to get it to actually charge and recognize the dock. I've updated the firmware tried everything. I would NOT recommend this unit - looks nice and the vacuum isn't that loud itself but it simply fails.
