I want to have a robot more than anything in my future house. It will look just like Kitty, my favourite cartoon character. It will dress in pink. It will always look clean because it has the self-clean system. It will be able to do all the housework with me. It is good to have someone to share the chores with. In my free time we can talk about school. It will be my friend. That is why I love it.

The kitty can lift heavy things
