The Hydrodisplacer is a gadget developed by Gadgetron in Ratchet & Clank. It is a handheld gadget that drains and fills pools of water when attached to a plug point, therefore "displacing" it. It makes use of quantum compression technology allowing it to hold up to 50,000 liters of water.
In the original Ratchet & Clank, it can be found by Clank while exploring outside in space in the Blarg Tactical Research Station in Nebula G34. In the 2016 re-imagined Ratchet & Clank, it is found on Aridia instead, after traversing an area with the Swingshot inside Skidd's Sports Shack.
The Hydrodisplacer can drain and fill pools of water by interacting with water plug points, allowing Ratchet to clear or fill a pool depending on which is required to progress. Hydro-Faucets are used to fill the Hydrodisplacer, and filling it will automatically convert them to a Hydro-Drain, where the Hydrodisplacer's water can be deposited.
The volume of water that can be contained within a Hydrodisplacer is 50,000 liters, far greater than the gadget's external volume may have indicated, and uses quantum compression technology to manipulate water particles and place them into a compression tank.
Behind the scenes
The Hydrodisplacer in the beta version of the game had a vastly different appearance than the final version.
