The Minion Expander is a RAREMinion upgrade that increases minion's usable area from 5x5 to 7x7 and minion collection rate by 5%. It is unlocked at Quartz V (5).
The effect of multiple Minion Expanders stacks up to the current maximum of two minion upgrades, which results in an usable area of 9x9 and a 10.25% collection rate buff.
Although these items increase the area the minion uses, additional space is not required for the collection rate bonus. The bonus is applied as soon as the Minion Expanders are put into the minion.
