00-24-00 Advertising, Fake? or Not?

Well, I am not going to say that all of advertising are fake, I just want to talk about some of advertisings are lying to the people, are lying to the society.
Why I said this? The reason is because some of my friends told me that the product they bought is not like the advertisings said that are very good or easy to use. So, what do you think about this? lying? or not?

From this advertisings, we can see the iRobot can stop if there are something in front of it, and it can control the direction by itself... So, when I first time saw it, I think it is amazing, and I should get one for my family.
However, after I talked to my friend, I changed my mind, the reason is because my friend told me that it did not like the advertising said that can stop by the stuff, it will keep getting through it.  And it also very noisy. So, it is not good enough.
Therefore, what do you think after you head this message?
It is fake? or not?

I think it is lying, and did not tell the people the truth.
So, what is the basic idea about the advertising?
Reality? Truth? Function?
I think the most important thing is do not lying to the people.
