VacMaster Sidekick: problems, parts and running costs

Checked: 2026-10-21

Summary

The Sidekick (manufacturer SKU VPSK) is a compact edge sealer that VacMaster lists at $89.00 direct (VacMaster store, 2026), and what you are buying is a spec sheet: dual piston pump, 12-inch seal bar, Dry, Gentle and Moist modes, a built-in bag cutter and roll storage, and a vacuum hose for VacMaster canisters and mason jars [1]. No owner history, no independent test and no entry in the brand’s own seal-time guide exist for it yet [1][6][7][11][12], so the money you will really spend is on consumables the warranty excludes — Teflon tape, lid gaskets and seal wire — plus bags and rolls, none of which has a published price or a replacement interval [4][8]. It is worth buying at or under $75 on the documented features, a fair buy at the $89.00 direct price, and poor value above $111, where the only higher price point is the $137.10 canister set [1][2].

Common problems and fixes

Opening the unit yourself can void the warranty — the warranty is void for repairs by anyone other than ARY, Inc. without prior authorization, and for goods tampered with or altered by anyone else, so replacing the seal tape on your own can fall inside that exclusion. Fix: get authorization in writing before you open the machine, and claim a faulty unit inside the first year instead of working on it. [4]
The 30-day return option ends when you open the box — regularly stocked items come back only if unused and unopened, in the original packaging, within 30 days of receipt, with return shipping at your cost and the refund paid after inspection. Fix: decide before you break the seal, because once you have opened and tried it you have effectively given the return up. [5]
“Dual piston” and “up to 5x longer” are claims nobody has checked — no vacuum level in mbar or inHg is published for the pump, and the freshness figure has no baseline, protocol or test method behind it. Fix: treat both as manufacturer copy rather than specifications; the pump’s real performance stays unknown until you own it. [1][3]
Canister and mason-jar use has no published flow rate — the hose is included and VacMaster canisters and mason jar attachments are supported, but no evacuation time is published, so a jar may or may not pull down to a hard vacuum. Fix: buy this machine for bag sealing, and take the canister bundle only if jar vacuuming is the point of the purchase. [1][3]
No maintenance schedule is published — the product page states no cleaning schedule, no bag-change interval and no service points, and the linked VPSK user manual could not be opened; the pump is nowhere described as oil-lubricated, although VacMaster sells vacuum pump oil for its chamber machines. Fix: ask the brand for the manual and a service schedule, and keep the chamber and vacuum channel clean as routine. [1][2]
The cutter blade is of unknown replaceability — blade type and whether the integrated cutter can be replaced are not published, and the cutter is one of the features with no field history. Fix: none published; a damaged or dull blade is a service item for ARY, Inc., since an unauthorized repair voids the warranty. [1][4]

Parts and consumables

VacMaster canisters — 16.91 oz small, 27.05 oz medium and 44 oz large, sold as bundles with the machine: $103.45 for the machine with a small canister and $137.10 for the three-piece set (VacMaster store, 2026). Optional, since the machine works as a bag sealer without them. [2][3]
Vacuum pump oil — the brand sells vacuum pump oil for its chamber machines, but no oil requirement is stated for the Sidekick and its pump is not described as oil-lubricated in any source. Do not budget for it until the manual says otherwise. [1][2]
Bag cutter blade — no part number, and replaceability is not published, so plan on a service visit rather than a spare part. [1]

Yearly running cost

Not enough data for a yearly total. The only recurring items the sources identify are those consumables — the pump is nowhere described as oil-lubricated, no cleaning, oil or filter-change interval is published, and no other running cost is documented [1][2]. Get a bag price and a seal-part price from the brand before buying, then add them to whatever interval your own use works out to.

When it is a good buy

VacMaster store, 2026: the machine alone at $89.00, the machine with a small canister at $103.45, and the machine with the three-piece canister set at $137.10 [1][2][3].

At or under $75: attractive on documented specs alone — dual piston pump, 12-inch bar, three seal modes, integrated cutter and roll storage, and the canister and mason-jar hose, at or below the level of comparable compact sealers. [1]
At $76-90, which is where the direct price sits: a reasonable buy for someone who accepts that there is no independent test data, no owner history and no published seal times for this model. [1][6][7]
At $91-110: the real question is whether you want the $103.45 bundle instead of the machine alone, since the lack of independent review and of manufacturer seal-time guidance stays the main disadvantage at that level. [3]
At $111-130: weak value, because the money goes into canisters rather than into a better sealer. [2]
Above $137: the $137.10 three-canister set is the only published price point in the range, so read it as a canister-set sale [2]; this model has no independent test coverage and no owner history of its own [11][12], so at that level a machine with measured performance and a long owner record is the better comparison.

Expect to buy it from the brand itself: VacMaster sells it direct, and while Target and Walmart carry VacMaster brand pages, no Sidekick listing turned up on either [1][9][10].

Alternatives, with the case for each:

VacMaster Sidekick with the small canister, $103.45 — the better choice when you want to pull a vacuum down on a canister straight out of the box instead of buying attachments separately. [3]
VacMaster Sidekick with the three-piece canister set, $137.10 — the better choice when you regularly canister several volumes at once, though the $89.00 machine is still doing the sealing work. [2]
