Robo-Vac

Robo-Vac is a utility familiar deployed by the Tinkerer class for 4 mana. Once placed, this autonomous vacuum bot scours the battlefield collecting pickups and shares the effects of those items with the entire team rather than just the cat who walks over them.

Robo-Vac is non-combat: it has no attacks and focuses entirely on pickup collection. It zips across the battlefield automatically, picking up coins, hearts, and other drops before enemies or your cats can reach them. This behavior is especially valuable in chaotic battles where spreading your cats out to collect pickups would expose them to attacks.

At 4 mana, Robo-Vac is one of the cheapest Tinkerer deployments and delivers consistent value in nearly every fight. Even in rooms with minimal drops, its team-wide sharing turns a single heart container into healing for every cat simultaneously. It upgrades into Robo Vacuum 2 with even greater efficiency.
