Steal a Brainrot is a popular Roblox experience that lets you collect a variety of Brainrots to earn money. Likewise, you can then buy new Brainrots by selling the ones you already have. One of the standout additions introduced in Update 52 is the Summer Fuse Machine, which allows you to combine existing Brainrots for a chance to unlock entirely new ones.
The Summer Fuse Machine features a bright beach-inspired appearance, blending sandy beige tones with ocean-blue colors to match the seasonal atmosphere. Along with its visual redesign, the update also introduces several new Brainrots across multiple rarities. So, if you want to make the most out of it, here’s a complete guide for Summer Fuse Machine in Steal a Brainrot.
How to Use the Summer Fuse Machine in Steal a Brainrot

The Summer Fuse Machine works very similarly to earlier fusion systems, such as the original Fuse Machine and Santa’s Fuse Machine. To start, pick the Brainrots you want to combine from your base and bring them to the machine. You can place up to four Brainrots inside, adding them one at a time to test different combinations and improve your chances of getting a stronger result.
After inserting your Brainrots, the machine will display the fusion duration along with the amount of in-game cash required. Once you confirm the process, the fusion begins automatically. When the timer finishes, return to the machine and press the E key to collect your newly fused Brainrot.
The quality of the Brainrots you use plays a major role in the outcome. Higher-rarity Brainrots generally increase the odds of receiving rare or powerful fusions, while weaker inputs are more likely to produce average results. Even so, fusion still involves randomness, so there is never a guaranteed high-tier reward.
