Running Ghost 2

I found the way through the zappers. But I'm now trapped in front of a gap. I know what I need to do to fill the gap however, this is another issue with my iPad.

If I grab a draggable and use it without letting go, I can get it up only one block height... It Does not go up any higher, so it cannot reach the gap.
If I grab a draggable and accidentally drop it, it never comes off the floor again.
If there is a slanted block nearby, I can get the draggable to move off the floor again, but it becomes uncontrollable after it reaches two block heights.

This is an impossible level for my iPad 3 .

Spoiler

Hit the slider from behind using the draggable, it will make slider moving faster and stronger to push the bot

@Kim Budi not possible. Once I have used it for the zapper situation, I can't use it for anything else. It falls to the floor...and remains there for life ;(
