The Most Advanced Machine

I bet that you would like to have a mower for your lawn
That hardly needed input and could run while you were gone.

I have a few fine models so, if you want my advice,
I'll go through some key features. I'm sure that will suffice.

I bet that you have never seen machines that looked this good.
You can even choose the color – you don't have to – but you could.

Not using toxic compounds, it's not harmful to the earth.
Now tell me, how much do you think something like this is worth?

Don't worry - you don't need to call technicians for repair.
It can fix itself - though it's slow, so please don't stare.

Still, want a newer model when the current one's worn out?
There's a built-in option, I assure without a doubt.

It only runs on water. What more could someone ask?
Invent something that's this complex – it is no easy task!

And if all this were not enough, it doubles as a pet.
Now, my friend, I have to ask… have you figured it out, yet?
