The catch
Instant Vortex Slim 6QT
At 17.78 inches deep, the narrow body has no Dehydrate program.
Side by side
Instant Vortex Slim 6QT vs Plus 4QT: Slim buys its capacity with extra counter depth
Quick verdict
The Slim fits if you have front-to-back room and often outgrow a four-quart basket. The older Plus 4QT fits a shallow counter or a dedicated Dehydrate program. Because they take up almost the same width, the Slim gets its extra capacity by asking for more depth.
Before you buy
Why, and what it costs you
Not every narrow kitchen is a Slim-shaped kitchen
The Slim is the useful upgrade when the gap between your kettle and stove is narrow but the counter is deep. On a shallow counter it can be the worse fit. Its body is about 36% deeper in exchange for 50% more nominal basket volume. Measure the full operating position, including the space to pull out a hot drawer. These body dimensions come from the original US manual and exact-model listing, and they are no promise that food batches grow by 50%.
Where this comes from
Instant Vortex Slim 6QT: 6 qt, 10.20 in wide and 17.78 in deep. Instant Vortex Plus 4QT: 4 qt, 10.1 in wide and 13.1 in deep. Depth difference is 4.68 in, divided by 13.1 gives about 36%.
The catch
Instant Vortex Plus 4QT
When your portions grow, four quarts can force another batch.

How we worked this out
Instant Vortex Slim 6QT: 6 qt, 10.20 in wide and 17.78 in deep. Instant Vortex Plus 4QT: 4 qt, 10.1 in wide and 13.1 in deep. Depth difference is 4.68 in, divided by 13.1 gives about 36%.
Drying fruit on weekends can undo the capacity upgrade
Someone who mainly reheats one meal but also dries sliced fruit gets both jobs covered by the Plus 4QT's listed programs. The Slim gives more room for dinner but drops the dedicated Dehydrate program. Notice that before you replace a smaller appliance that already handles your weekend routine. Neither capacity rating reveals the usable drying area or how many layers a recipe allows.
How we worked this out
Instant Vortex Slim 6QT: Five documented programs are Air Fry, Roast, Bake, Broil and Reheat. Instant Vortex Plus 4QT: The six documented programs also include Dehydrate.
More quarts do not fix the need for two dinner temperatures
Going from four to six quarts still leaves one cooking zone if your main and side need different settings. Room for more of the same food may be what you gain, but a second temperature still means another session or another appliance. That matters most when a child wants a plain portion and adults want a differently cooked dish. A larger basket does not turn either model into a dual-zone fryer.
How we worked this out
Instant Vortex Slim 6QT: One six-quart cooking zone. Instant Vortex Plus 4QT: One four-quart cooking zone.

Spec by spec
Where they really differ
| Spec | Instant Vortex Slim 6QT | Instant Vortex Plus 4QT | In practice |

| Body width | 10.20 in | 10.1 in | Only 0.10 inch separates the widths. |
| Body depth | 17.78 in | 13.1 in | Front to back, the Slim needs 4.68 more inches, before ventilation and drawer movement are counted. |
| Programs | Five, without Dehydrate | Six, including Dehydrate | The dedicated low-temperature drying program is on the smaller machine. |
