In Cube Combination / “cube combiner” on Roblox, Magnet Storage is the storage upgrade that auto-collects nearby items, so you usually use it when you want a factory setup to run without manually picking things up.

How it works

  • It stores items like a normal storage cube, but it also pulls in items from about a 7.5-stud radius around it.
  • Basic Storage takes input from the top and outputs from the front, and it is used as a step toward Magnet Storage.
  • The wiki lists Magnet Storage as a Tier 2 upgrade from Basic Storage using a Magnet Cube.

Simple setup

  1. Make a Basic Storage first.
  1. Combine it with a Magnet Cube to turn it into Magnet Storage.
  1. Place it near the area where items spawn or move through your factory so it can pull them in automatically.

Why players use it

  • It is useful for factory builds because it reduces item clutter and manual collection.
  • It helps with automatic collection loops, especially when paired with conveyors and other processing cubes.

Common confusion

A lot of tutorials and videos mix old and new recipes, so if something does not work, it may be from an older version of the game. The safest reference I found is the wiki recipe path for Basic Storage to Magnet Storage.

Quick example

If you have cubes dropping on the ground near a storage machine, putting Magnet Storage beside that drop zone lets it vacuum the items in automatically instead of waiting for you to collect them.

TL;DR: Build Basic Storage first, combine it with a Magnet Cube, then place it close to your item flow so it pulls nearby items automatically.
