not use it right?

I'm going to have it cleaned first.

Can't we say"i'm going to have it to be cleaned first?

What's the difference grammarically?

gramatically.......

This is a very hard question to answer.

For native english speakers the "to be" in this sentance are extra words that are not needed to make sense of the sentence.

"I will allow it to be cleaned" makes perfect sense though.

Thanks, dadpad;) it makes sense...

Re: not use it right?


These are semi-passive structures, CF, and the word order is very important.

There are two of these semi-passives;

1) Have something done --> have it cleaned

2) Get something done --> get it cleaned

They mean;

3) "Have somebody do something" //

4) "Get somebody to do something"

I'm going to get Sandy to bake a cake.

but since the 'somebody' is often unknown and therefore unimportant, we end up with the passive structures 1) and 2) above.

Perhaps you're confusing these with the structure marked number 4), wherein an agent is mentioned. Then 'to' is used in that collocation.
