If you notice bObi acting differently, try this home check up test. It will let you know whether or not bObi's sensors, motors, and parts are all working properly. After performing this diagnostic, you'll know if an error was caused by something environmental or internal.
When you first receive bObi, the battery is not plugged in. Luckily all you need is a Phillips head screwdriver to install it before bObi starts working for you.
bObi has a mop cloth and trailing bar that can be used any time you want her to wash tile or hardwood flooring.
