Our take
The Oster 6871 is retained as an evidence-limited model because the frozen candidate title and a model-specific secondary listing both describe a 12-speed blender with a food-processor attachment. The secondary listing also reports a 450-W motor, 120-V supply, pulse, and a six-cup capacity, but it does not establish that the six-cup vessel is a processor bowl. Its item-specific components field lists a blender and no processor parts inventory. No Oster maker manual or mapping from the historical Amazon ASIN to this exact model was found. Treat the link as a tagged model search and confirm the delivered machine before using it to satisfy a processor need.
A shopper verifying an Oster 6871 attachment set who can inspect the actual bowl, blade or discs, and model plate before relying on it as a food processor..
Not for a shopper who needs a confirmed food-processor bowl capacity, named slicing/shredding discs, a verified attachment package, or a proven 120-V / 60-Hz rating.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The 6871 model code is repeated by a model-specific secondary listing and the frozen food-processor combo title.
- The secondary listing describes a twelve-speed blender with pulse, though those details are not maker-confirmed.
- A tagged exact-model search can help a shopper compare the model code without treating the historical ASIN as proven.
What to weigh up
- The six-cup figure is not assigned to a processor bowl because the listed vessel is unspecified.
- The exact listing's component field does not confirm the food-processor attachment or its cutting tools.
- The available model evidence is secondary, and no matching Oster manual or exact ASIN crosswalk was found.
The key details
| Model covered | 6871 |
|---|---|
| Main bowl capacity | A secondary listing states six cups but does not identify whether that capacity belongs to a blender jar or processor bowl; processor capacity remains unknown. |
| Small-batch bowl | A separate smaller processor bowl is not established by the available item record. |
| Slicing and shredding | The secondary listing mentions slice and shred capabilities, but no exact processor discs or their package contents are documented. |
| Special attachment | A food-processor attachment appears in the frozen title and secondary listing title; the exact attachment set is unverified. |
| Dough blade | A dedicated dough blade is not confirmed by a parts list or model manual. |
| Integrated cooking | Integrated heating is not described in the available model-specific record. |

What the features mean for you
Keep the model clue separate from the old ASIN
The frozen source row describes an Oster 12-speed blender with a food-processor attachment and carries an old Amazon ASIN. That Amazon URL did not load during the current check. A separate model-specific listing names Oster 6871 and repeats the blender-plus-processor-attachment wording, so the model can be searched as 6871. This does not prove that the historical Amazon ASIN mapped to that listing, that a current offer uses the same package, or that every suffix belongs to the same configuration. The review therefore keeps the 6871 model record and the unknown historic offer boundary visible. Use the tagged search to inspect exact item details rather than relying on the frozen link. [bowlCapacityCups]
Do not assign the six-cup claim to the processor bowl
The secondary listing states six cups but does not identify the vessel in a way that separates a blender jar from a food-processor work bowl. Because a combo product can contain differently shaped vessels for different jobs, copying the largest number into the processor capacity field could mislead a shopper who needs a bowl for chopping or slicing. The processor-bowl capacity therefore remains unknown. Before purchase, inspect the actual processor bowl markings or its manual and keep the blender jar's measure separate. Until a source identifies the processor vessel and its usable fill, this model should not pass a hard capacity requirement. [bowlCapacityCups, smallBowl]
Treat speed and wattage as seller data
The seller page reports twelve speed settings, pulse, 450 watts, and 120 volts. Those are model-specific secondary listing fields, not an Oster instruction book or a verified rating plate. They can help a shopper recognize the type of listing but do not establish measured power at the blade, processing speed, or food results. The seller's page does not provide frequency, so 120 volts alone does not satisfy the finder’s 120-V / 60-Hz check. A buyer should ask for a clear image of the unit's nameplate and operating manual, especially when the machine will be used in a business or where electrical compatibility is a strict condition. [northAmericanVoltage]
Attachment wording is not an included-parts list
Both the frozen title and the secondary listing title mention a food-processor attachment, but the seller's component field names a blender and does not inventory the processor vessel, blade, spindle, or discs. That leaves the principal food-processing question unanswered: which parts actually make the combination useful for the jobs a shopper has in mind? The same listing mentions slice and shred capabilities, yet no specific disc or exact kit is documented. Keep those values unknown rather than assuming a cutting function follows from a broad appliance-capability field. Ask the seller to show the exact processor bowl and its parts together with the 6871 label. [sliceShred, dicingKit]
The evidence supports caution, not a performance ranking
There is no model manual in the saved evidence that explains assembly, safe fill, cleaning, blade handling, or which ingredients the processor attachment accepts. The seller's twelve-speed and pulse fields should not be used to infer a better texture or faster preparation than a single-speed machine. Nor does the old marketplace record supply verified buyer feedback for this review. For a shopper who already owns a 6871 base, a model search and parts diagram may help identify a compatible attachment. For someone choosing a new processor, a documented bowl size and named parts from a manual provide a firmer basis than the evidence available here. [sliceShred, doughBlade]
Confirm the exact set before treating it as a processor
The available facts describe a combination concept, not a fully documented food-processor package. Before choosing an offer, verify that the seller's item includes a processor work bowl, the matching lid and drive, and the exact blade or discs needed for the task. Confirm whether six cups refers to the blender vessel, and check the model plate, voltage, frequency, and any different suffix. This is a practical verification list because the published record leaves those parts unresolved. If the attachment cannot be shown, compare a bowl-based model whose official or exact manual identifies its components and capacity. [smallBowl, northAmericanVoltage]
What else to compare
For a documented small-bowl combo with a named processor assembly, compare the saved Ninja Storm QB751Q guide record; for a conventional processor with a measured bowl and listed discs, compare models whose manuals identify those exact parts.
Before you buy
Does six cups mean a six-cup processor bowl?
That is not established. The secondary listing says six cups but does not identify the vessel as the food-processor bowl.
Does the historical Amazon ASIN prove the 6871 package?
No. The old Amazon URL failed to load and was not crosswalked to the secondary 6871 listing.
Are slicing and shredding discs confirmed in the box?
No. The secondary listing mentions capabilities but gives no exact processor parts inventory or disc references.
Is 120 volts enough to confirm North American compatibility?
No. The secondary listing omits frequency and is not a verified rating-plate source; confirm the exact unit's electrical label.
