Man's best friend

It's safe to say that Isaac has gotten over his fear of the Roomba. Now he spends many minutes a day playing with it. (One of his more expensive toys, but by child number three as long as there is no potential for permanent disfigurement, and there's at least the possibility that he won't actually break the appliance in question, you pretty much go with the flow.)

Isaac also figured out that if he is quick enough he can climb on it after pushing the start button and take a ride. Here he is taking it for a spin.
