The Vac-U 4000, commonly shorted to the Vac-U, was a gadget in Ratchet & Clank: All 4 One. It was used to suck up objects, other playable characters, or enemies. It was often used to suck up other playable characters, and then shoot them out to reach the other side of a gap and activate a button to draw a bridge so the whole team could get to the next part of a level. The Vac-U could also be used to suck up Voltergeists and shoot them out into a socket to extend a bridge or open a door. The Vac-U could also be used to shoot other players into the air for a stomp.
The Vac-U bore resemblance to the Suck Cannon. Furthermore, it could be used in a similar manner, however, only one enemy could be sucked in and shot out at a time, albeit larger ones at that.
After a character is in the barrel, a trajectory line appears. If the line is blue, it means it is in the correct direction and position to take the character to the other side. If it is red, it cannot be used to shoot the character out.
- The use of the name "Vac-U" probably refers to the fact that the gadget can be used to vacuum other players, or vacuum you.
- The Vac-U uses Zepto-Shrink technology designed for Ephemeris to store numerous critters.
- A feature from the game was cut that if two characters equipped the Vac-U and sucked up an Elasta-Shock, anything between the two characters would be destroyed by a laser wire that connects the Vac-Us together.
