Which is better for a family of four?

The 8-quart Duo Plus gives more headroom for batch cooking and leftovers. The 6-quart Pro is enough for most four-person meals and fits smaller kitchens.

Does the Duo Plus have sous vide?

No. Sous vide is a Pro 6-Quart feature. The Duo Plus lists 9 programs: rice, slow cooking, pasta, sauté, soup, steam, yogurt, and pressure cooking presets.

Is the Pro worth the extra money?

It is not extra: at $169.95 at Williams-Sonoma versus $172.26 at Walmart as of November 8, 2026, the Pro is slightly cheaper. You pay less but give up 2 quarts and app control.

Which one is easier to store?

The Pro 6-Quart, at about 13 x 12.7 x 12.8 inches. The Duo Plus is 15 x 15 x 14 inches and weighs 19.7 lb.

Can I control either one from my phone?

Only the Duo Plus has built-in Wi-Fi and mobile app control. The Pro 6-Quart is controlled from its touchscreen only.

Both are stainless-steel-body Instant Pots with 1200-watt heating and UL or ULC listing, so lifespan depends on the sealing ring and valve care. The Pro includes a spare sealing ring, which helps.
