I’m always looking for ways to cut down on food waste and keep things fresh longer, especially with leftovers, pantry items, and bulk buys. The Roboseal Jar Sealer kept popping up as a solution, promising to vacuum-seal jars with ease and save me both time and money. It sounded like a dream tool for meal preppers and home organizers, so I decided to put it to the test in my own kitchen.
What Is the Roboseal Jar Sealer?
The Roboseal Jar Sealer is a countertop gadget designed to vacuum-seal mason jars and similar containers. It works by extracting air from inside the jar to create an airtight seal, which is supposed to extend food shelf life, prevent staleness, and keep flavors intact. It’s marketed as a budget-friendly alternative to bulky vacuum sealing machines, with a focus on convenience and ease of use.
Why I Bought It
I picked it up mainly because I often buy snacks and pantry staples in bulk… nuts, dried fruit, coffee beans, and even spices. Once opened, they tend to lose freshness pretty quickly. The idea of being able to seal jars over and over without expensive vacuum bags seemed too good to pass up.
My Experience Using It
Setting it up was simple enough: charge it, place the sealer over the jar lid, and press the button. At first, I was impressed, it did create a seal, and I felt confident my food would stay fresher. But after using it for about a week, my enthusiasm started fading.
I tried it on different jars, coffee, almonds, and even a homemade sauce I wanted to preserve. While the device did remove some air, the seal wasn’t always reliable. With smaller jars, the seal held for a few days, but larger jars often lost their vacuum within 24–48 hours. The inconsistency made me question whether it was actually protecting my food or just giving me the illusion of freshness.
Another issue was the noise and heat. The motor was louder than expected, and after sealing a few jars in a row, the device felt hot to the touch. It didn’t break, but it didn’t give me confidence in its durability. Over time, I found myself reaching for it less and less because I didn’t fully trust it to do its job.
In short, it’s not a scam, as it works to an extent, but it didn’t live up to the promise of keeping everything airtight for long.
Pros
- Easy to set up and use
- Compact and rechargeable
- Works well on smaller jars for short-term freshness
Cons
- Inconsistent sealing, especially on larger jars
- Noise and overheating with repeated use
- Not as effective as traditional vacuum sealers
How to Use / Application Process
- Place the compatible jar lid on your mason jar.
- Position the Roboseal over the lid.
- Press the power button to start the vacuum process.
- Wait for the motor to stop, signaling a seal.
- Store jar as usual, checking periodically if the seal holds.
Where to Buy & Price
The Roboseal Jar Sealer is typically sold through its official website and sometimes appears on Amazon. Prices vary, but most listings place it around $30–$40 USD, often marketed with discounts to make it look like a “limited-time deal.”
Is It a Scam?
No, the Roboseal isn’t a scam, it does work to some degree. But based on my experience, it’s not as effective or long-lasting as advertised. If you’re expecting industrial-level sealing power, you’ll likely be disappointed.
Alternatives That Actually Work

- FoodSaver Vacuum Sealing System
- ZWILLING Fresh & Save Vacuum Sealer
- Mason Jar Vacuum Sealer Kit (FoodSaver-compatible)
Conclusion
The Roboseal Jar Sealer seemed like a smart, budget-friendly tool for extending food freshness, but in reality, it left me underwhelmed. It’s fine for sealing small jars for a few days, but anything beyond that, and the promise of long-term freshness… fell flat. If you’re serious about keeping your food sealed and fresh, I’d recommend investing in a more reliable vacuum-sealing system.
