Why we tested
KitchenAid’s food processor line has lived in the shadow of Cuisinart for years, but the KFP1466ER occupies a specific niche: buyers who already own KitchenAid stand mixers, hand mixers, or blenders and want a visually cohesive counter. That is a real consideration in modern kitchen design, but it should not cost performance. We tested the KFP1466ER at retail alongside the Cuisinart DFP-14BCWN and Breville BFP800XL for two months to see where the KitchenAid genuinely competes and where it concedes ground.
How we tested
Identical protocol to our full food processor series: onion dice evenness (one large yellow onion, 10 pulses, outlier percentage measured across five tests), carrot slicing consistency (20 consecutive slices, thickness variance measured with caliper), noise level (calibrated sound meter at 18 inches, five readings averaged), bowl leak test (10 cups of tomato salsa, 30 seconds continuous), and cleaning assessment (hand rinse plus dishwasher top-rack cycle). We also specifically tested the ExactSlice lever at three positions — minimum, center, and maximum — on raw potatoes and English cucumbers.

Chopping: slightly behind the Cuisinart
This is where we have to be honest about the $80 premium. The KFP1466ER’s 600-watt motor is 120 watts shy of the Cuisinart’s 720W, and in the onion dice test it shows. Our outlier rate across five tests averaged 14%, compared to 11% for the Cuisinart. The difference comes down to blade speed consistency through the pulse: at lower wattage, the blade decelerates slightly faster during each pulse contact, which reduces the effective cutting force on tougher food pieces and leaves more intact chunks.
On soft foods (herbs, cooked vegetables, cooked beans) the difference disappears. For a smooth hummus or herb pesto, both machines perform identically at equivalent durations. The gap appears specifically with raw dense vegetables, which is a frequent use case for food processors.
Continuous mode performance on carrots was fine. The motor did not bog or stall on a 300g batch of 1-inch carrot chunks. The output texture was appropriate for soup prep, just slightly less uniform than the Cuisinart under identical conditions.
Slicing: the ExactSlice lever is a genuine advantage
The reversible ExactSlice lever is the KFP1466ER’s clearest win over the Cuisinart in this price class. Dialing from thin (approximately 2mm on our measurements) to thick (approximately 6mm) without swapping discs is faster and less fiddly than pulling and remounting a separate disc. In a session where you are slicing both cucumbers for a salad (thin) and potatoes for a gratin (thick), the lever saves 90 seconds and one trip to the disc drawer.
Measured thickness variance at center position (approximately 4mm) was plus or minus 0.25mm on 20 carrot slices — comparable to the Cuisinart’s 0.3mm and meaningfully below the Hamilton Beach’s 0.6mm. At the thin setting, cucumber slices at 1.9mm average with 0.15mm variance are excellent for a cold-cut presentation layer.
The included reversible shredding disc (fine on one face, medium on the other) is a nice inclusion that eliminates disc storage for two shred sizes.
Noise and bowl seal: two real advantages
At 79 dB under load processing carrots, the KFP1466ER is quieter than the Cuisinart (82 dB) by a measurable 3 dB, roughly a 25% reduction in perceived loudness. The motor housing and bowl wall thickness are noticeably more substantial than the Cuisinart’s, and the bowl lid’s rubber perimeter gasket absorbs more vibration resonance. For an open-plan kitchen where the processor runs while you are nearby, this difference is real over time.
The bowl seal performed perfectly in our leak test. Ten cups of watery salsa processed for 30 seconds produced zero seepage at the bowl-to-base junction. The Cuisinart produced a small drip under the same conditions. If you regularly process soups, sauces, or fruit smoothies in a food processor, the KitchenAid’s seal design is a practical advantage.
Cleaning: dishwasher-safe, no surprises
All components — S-blade, shredding disc, slicing disc housing, main and mini bowls, lids — are top-rack dishwasher safe and emerged from 20+ cycles undamaged and without warping. The ExactSlice housing has a few crevices around the lever mechanism that required a bottle brush after sticky foods (fruit, cheese), but this is manageable with a quick hand rinse before loading.
Who should buy this
Buy the KitchenAid KFP1466ER if you own other KitchenAid appliances and value visual kitchen coherence, want the ExactSlice lever’s convenience over fixed-disc swaps, or process liquids frequently and value the tighter bowl seal. The noise advantage over the Cuisinart is also real for noise-sensitive households.
Skip it if chopping performance and value are the primary criteria — the Cuisinart DFP-14BCWN wins on both at $80 less. For an extra $120 over this machine, the Breville Sous Chef 16 offers substantially more disc range and motor headroom.
KitchenAid KFP1466ER 14-Cup Food Processor vs. the competition
| Product | Verdict |

Should you buy the KitchenAid KFP1466ER 14-Cup Food Processor?
The KitchenAid KFP1466ER is a well-built 14-cup food processor that matches or slightly surpasses the Cuisinart DFP-14BCWN on noise levels and bowl seal quality, while trailing it on raw chopping evenness and value. At $280, it sits in an awkward middle ground: $80 more than the Cuisinart with modest performance gains, and $120 less than the Breville Sous Chef with fewer features. Best suited to buyers already invested in KitchenAid's kitchen ecosystem who want visual continuity on the counter.
Frequently asked questions
What is the ExactSlice lever on the KitchenAid KFP1466ER?+
It is a sliding lever on the external feed tube housing that adjusts slice thickness from thin to thick without swapping discs. It works by altering how much the disc flexes relative to the cutting edge, giving you a continuous range rather than fixed thicknesses. Thin setting produces approximately 2mm slices, thick setting approximately 6mm. Reproducibility between sessions is good if you mark your preferred position.
Is the KitchenAid 14-Cup Food Processor better than the Cuisinart DFP-14BCWN?+
On specific dimensions yes: it is quieter (79 dB vs 82 dB), the bowl seal is tighter on liquid-heavy tasks, and the ExactSlice lever provides more slicing flexibility without extra discs. On chopping evenness (our most-weighted test) the Cuisinart scores better. For most buyers the Cuisinart is the stronger value at $80 less.
Can I use KitchenAid food processor discs from older models with the KFP1466ER?+
Generally yes for disc accessories made for the 14-cup platform, but compatibility varies by generation. KitchenAid's disc systems use a standard spindle but the disc height and locking tab have changed across generations. Check KitchenAid's compatibility guide before purchasing third-party or legacy discs.
Does the mini bowl work independently from the main 14-cup bowl?+
The 3.5-cup mini bowl nests inside the main bowl and uses the same motor drive. You cannot run the mini bowl on its own without the outer bowl in place. This is standard design for dual-bowl processors. The mini bowl is ideal for small-batch tasks like mincing garlic, making fresh salsa in small quantities, or processing a single cup of nuts.
