Ninja PREPi (PN301 vs. PN351): Specs, Price, and Which Version to Buy

Research-based look at Ninja's new PREPi prep-and-store system: PN301 vs. PN351 specs, what the dicing kit adds, launch prices, and who should skip it.

Buy the Ninja PREPi PN301 if you mostly chop, puree, slice, and shred; buy the PN351 (or a PN301 dicing-kit bundle) if you dice vegetables often. The two share the same 500-watt motor, the same 5-cup and 7-cup bowls with storage lids, and the same blade and discs. The only difference is the Dicing Kit, and as of Oct. 6, 2026, getting it in the box ($229.99) is $9.99 cheaper than adding it later ($179.99 plus $59.99).

SharkNinja launched the PREPi on Oct. 2, 2026, and calls it a “prep + store system” rather than a food processor. This is a research-based overview built from SharkNinja’s press release and product pages, plus published hands-on coverage from CNET. We have not tested the PREPi ourselves, so there is no rating or verdict here.

What’s new about the Ninja PREPi?

Most food processors put a heavy motor in the base and stack the bowl on top. The PREPi flips that. CNET’s hands-on describes a compact motor pod that snaps onto the lid and sits on top of the bowl, with an eject button to pop it back out. SharkNinja’s spec pages still call that part the “500-Watt Motor Base.”

The other idea is that the work bowl doubles as the serving dish and the storage container. Each configuration ships with two bowls, a 5-cup and a 7-cup, and each bowl gets its own spindle and snap-on storage lid. You prep in one bowl, pull the blade and spindle, lid it, and put it in the fridge, while the other bowl is free for the next job.

SharkNinja lists these functions:

  • Chop and puree with one blade
  • Slice and shred with a reversible disc (flip it to switch)
  • Crinkle-cut with a separate disc
  • Dice with the Dicing Kit, which is included in the PN351 and sold separately for the PN301
  • A 3-part feed chute that adjusts for different ingredient widths

PN301 vs. PN351: what’s in the box

Specs and box contents come from SharkNinja’s PN301 and PN351 product pages. Prices are SharkNinja.com prices as of Oct. 6, 2026.

SharkNinja’s Oct. 2 release quoted launch prices of $179 and $229; the product pages show $179.99 and $229.99.

What does the Dicing Kit add?

The Dicing Kit (model XSKPN3DICGKIT, $59.99 on SharkNinja.com as of Oct. 6, 2026) comes with a dicer top, dicer blade, dicer bottom, dicer spindle, and a grid pick for clearing the grid. CNET reports that it fits inside the top of the larger bowl without the regular spindle.

Do the math before you decide you’ll add it later:

Path to dicingPrice (SharkNinja.com, Oct. 6, 2026)
PN351 or a PN301 dicing bundle$229.99
PN301 now, Dicing Kit later$179.99 + $59.99 = $239.98

If you’re not sure you’ll dice often, the PN301 still covers chopping, pureeing, slicing, shredding, and crinkle-cutting. CNET also noted that food can get stuck in the dicing kit, so it isn’t a must-have for everyone.

What hands-on reviewers liked and disliked

CNET’s hands-on review is the most detailed published test so far. In summary:

  • Liked: the two-bowl setup that lets you prep several ingredients without washing the bowl between them, lids that turn the bowls into storage containers, a light and compact motor pod, a lid that unclips easily for scraping, and a versatile feed chute. CNET says everything except the motor pod can go in the dishwasher.
  • Disliked: no handles on either bowl, which makes scraping out hummus or pesto awkward; lid clips that can take some fiddling to lock; a rounded bowl shape that can leave small pieces out of the blade’s reach; and lots of separate parts that don’t nest for storage.

CNET’s bottom line was that the PREPi isn’t the most powerful or best-value food processor for its size, but as a meal-prep system it’s in a class of its own.

Reliability, safety, and repairability

The PREPi went on sale on Oct. 2, 2026, so there’s no long-term reliability data yet. What you can check today:

Warranty. SharkNinja lists a one-year limited warranty on both the PN301 and PN351. That’s typical for a countertop prep appliance, but shorter than the coverage some premium food processors carry. Keep your receipt and register the unit.

Replacement parts. SharkNinja sells the Dicing Kit separately, and its PN301 page mentions additional PREPi bowls, so accessories are part of the plan. Motor units on countertop appliances like this are generally not owner-serviceable. If the motor fails, contact SharkNinja support rather than opening it.

Safety interlock. CNET notes that the start button lights up only when the motor pod is seated correctly, and that the lid clips are a safety feature. Don’t try to defeat them.

We found no SharkNinja recall notice for the PREPi as of Oct. 6, 2026. If you buy later, check CPSC recalls for the model number on your unit.

Who should buy the Ninja PREPi, and who should skip it?

The PN301 makes sense if you:

  • Batch-prep salads, slaws, sauces, or salsas and want to store them in the same bowl you made them in
  • Mostly chop, puree, slice, and shred, and don’t need uniform dice
  • Have limited counter or cabinet space; SharkNinja lists the unit at 9.3” x 9.3” x 10”

Get the PN351 or a PN301 dicing bundle if you:

  • Dice onions, peppers, potatoes, or tomatoes several times a week
  • Think you’ll want the Dicing Kit eventually, since buying it later costs $9.99 more at current SharkNinja prices

Skip the PREPi if you:

  • Make big batches, such as soups for a crowd; the largest bowl holds 7 cups
  • Want the most power or the best value per cup of capacity, which CNET says is not this system’s strength
  • Want bowl handles or a straight-walled bowl for scraping out thick dips
  • Prefer a product with years of owner reliability reports

Bottom line

The Ninja PREPi is a new 500-watt prep-and-store system with the motor on top, two lidded bowls (5 and 7 cups), and a one-year limited warranty. The PN301 ($179.99) and PN351 ($229.99) are the same machine except for the Dicing Kit, so the choice comes down to how often you dice. If you’re shopping during Prime Big Deal Days on Oct. 6 and 7, compare the exact model number and box contents across retailers, not just the color.

Frequently asked questions

What is the difference between the Ninja PREPi PN301 and PN351?

The PN351 is the PN301 plus the PREPi Dicing Kit. Both have the same 500-watt motor, a 5-cup and a 7-cup bowl with storage lids, a chop and puree blade, a reversible slice and shred disc, and a crinkle-cut disc. SharkNinja listed the PN301 at $179.99 and the PN351 at $229.99 as of Oct. 6, 2026.

Does the Ninja PREPi come with a dicing kit?

Only some versions do. The PN351 and SharkNinja's PN301 dicing-kit bundles include it. The standard PN301 does not; the Dicing Kit (model XSKPN3DICGKIT) is sold separately for $59.99 on SharkNinja.com as of Oct. 6, 2026.

Is it cheaper to buy the PN351 or add the dicing kit later?

At SharkNinja.com prices checked on Oct. 6, 2026, the PN351 is cheaper. A PN301 at $179.99 plus the $59.99 Dicing Kit totals $239.98, which is $9.99 more than the $229.99 PN351.

How powerful is the Ninja PREPi motor?

SharkNinja rates the PREPi at 500 watts, 120 volts, with a 31.5-inch cord. The motor unit sits on top of the bowl and lid rather than in a base underneath, which is the reverse of most food processors.

What size bowls does the Ninja PREPi have?

Every PREPi configuration includes a 5-cup bowl and a 7-cup bowl, each with its own spindle and storage lid. The idea is to prep in one bowl, then serve from it or snap on the lid and refrigerate it.

What warranty does the Ninja PREPi have?

SharkNinja lists a one-year limited warranty on the PN301 and PN351 product pages. Check the warranty terms included with your unit for exclusions and registration requirements.
