The T6i Rebel has a "three digit" model number. The Rebel bodies with "four digit" numbers, like the T7 / 2000D cameras, do not have sensor cleaning. They are pretty bare bones cameras.
ALL Canon EOS cameras made since 2007 have the EOS integrated cleaning system. The only exceptions are the very stripped down T3, T5, T6, and T7 beginner models.

You got a very capable camera. Lots of features to learn. Remember lenses are where its at so invest in the best lenses you can and you will have a fine outfit.
