Add-Ons are Items that can be toggled in the Item-Menu. Many of them are cosmetic, and it is only possible to have one of each cosmetic type (one skin, one step effect, one aura and one pet) active at a time. Detectors and boosters, however, assist in-game in different ways and can all be active at the same time.
Detectors help to detect items, by emitting an impulse and displaying the number of the detected item, upon entering the room.
