The pantry has a hidden cost too

Jars Keep Food Organized. Air Still Gets In.

A screwed-on lid traps a jar full of air with your food. That air is what goes stale, rancid and moldy. Pull it out and the same jar keeps things fresh for weeks longer.

Did you know?

Oxygen is what turns nuts rancid and crackers soft.

A vacuum-sealed jar holds almost none of it, so flavor, crunch and color last far longer than in a jar that is simply closed.

Why the Usual Options Fall Short

Struggling with a manual hand-pump jar sealer

Hand Pumps

  • Dozens of squeezes per jar
  • Slips off wide-mouth lids
  • You guess when it is sealed
A countertop sealer with a hose attachment for jars

Hose Attachments

  • Need a bulky countertop machine
  • Hose and adapter to store and lose
  • Tied to an outlet
A crowded shelf of plastic containers

Plastic Containers

  • Seal a pocket of air in every lid
  • Stain, warp and hold odors
  • Not airtight for long

The RoboSeal way

Set it on the lid, press once. The motor pulls the air out, the lid clicks down, and it stops by itself. Regular or wide-mouth, glass jars you already own.

  • One press, automatic stop
  • Regular and wide-mouth jars

Very good product★★★★★

This thing actually works. I love fruit but much of it goes bad in a couple of days. This product extends the fruit’s life 3 to 5 to 7 days

Frequently asked questions

Still Have Questions?

Which jars does RoboSeal fit?
Standard mason jars in both sizes: regular-mouth (about 2.76 in) and wide-mouth (about 3.39 in). The removable converter switches between them.
Do I need special lids?
Use the flat metal lids that come with mason jars. RoboSeal includes 10 BPA-free lids (5 regular, 5 wide) so you can start right away; standard replacement lids work too.
Do I need the screw ring?
No. RoboSeal seals the flat lid directly. Add the ring afterwards if you want extra protection for transport.
How do I open a sealed jar?
Lift the edge of the lid with a spoon handle or a lid lifter to release the vacuum, then reseal with RoboSeal when you are done.
Can I seal liquids like soups or sauces?
Yes, as long as there is headspace in the jar. Leave about an inch at the top so nothing is pulled into the sealer.
How long does the battery last?
RoboSeal recharges over USB-C, and the digital indicator on top shows the remaining charge so you are never caught out mid-batch.
Is this the same as canning?
No. Vacuum sealing removes air to keep food fresh longer; it is not a substitute for heat-process canning of low-acid foods for shelf storage.
Does it come with a warranty?
Yes. RoboSeal is covered by a 1-year warranty against manufacturer defects, plus a 30-day risk-free trial.
