Oster package comparison
Oster blender-and-chopper combos or the ten-cup processor?
Choose between two hybrid packages and a dedicated processor
Oster's current U.S. blender-and-processor combo directory groups two white or brushed-metal products with a separate small chopper attachment. It also lists a distinct ten-cup Easy-Touch bowl processor. The useful first question is not which motor has the larger wattage: it is whether the appliance you need most is a blender, a small prep bowl, or a full-size work bowl with processing discs.
SAP 2197995: white blender and three-cup processor vessel
The Classic 2-in-1 Kitchen System page identifies SAP 2197995 and lists a six-cup BPA-free blender jar, a separate three-cup BPA-free food-processor attachment and a 700-watt base with seven blender speeds including pulse. Oster describes the small attachment for chopping, dicing and grinding, but neither the product page nor its linked Classic Blender manual provides the attachment's blade geometry, task capacities or processor-speed schedule. The page's broad “dicing” description is not an included grid-dicer specification. The family manual names four BLSTBKP identifiers without mapping them to this SAP, so the retail model-number bridge remains unstated.
6878 / SAP 2136851: brushed metal with glass pitcher
The second combo is the Classic Series 16-Speed Blender with Food Chopper. Oster Consumer Care on the exact listing identifies model 6878, and SAP 2136851 distinguishes the brushed-nickel package. Its page names a six-cup Boroclass glass blender jar, three-cup BPA-free chopper vessel and stainless-steel S blade, with a 700-watt base and 16 blender speeds. It therefore has the same listed small-vessel rating and motor wattage as SAP 2197995, but a specified chopper blade, a glass pitcher and a different speed count. Do not convert speed-count or jar-material differences into a chopping-performance score: neither combo page gives a chopper task chart, and the linked general blender booklets do not detail the processor attachment's operating limits.
2142993: larger bowl and dedicated processing tools
The 2142993 Easy-Touch model is the direct comparison if the processor rather than blender is the main job. Its exact U.S. package lists a ten-cup bowl, reversible slicing/shredding disc and dough blade alongside the S blade. Its inspected guide supplies task-specific bowl amounts and dishwasher directions, though its flour guidance conflicts between a procedure and a separate chart, so the maximum flour amount remains unresolved. The bowl processor has a larger capacity label and named tools that the combo pages do not identify. It is not a like-for-like comparison of blending, but it is a better documented choice for repeated disc work.
Use tools and instructions as the boundary
The combo listings say their jars and attachments are dishwasher-safe, but the blender-family manuals' top-rack rule concerns the blender seal and threaded jar base; it does not establish the processor attachment's rack placement. The combo manuals also omit task-by-task limits for the small processor vessel. By contrast, the 2142993 guide supplies separate amounts for its work-bowl tasks and warns against assuming its ten-cup rating is a universal batch maximum. In all three cases, a bowl rating is a comparison label, not a promise that every ingredient can be processed to the brim.
A practical buying path
Pick SAP 2197995 if you prefer a white, BPA-free jar system and need both blending and modest processor work, while accepting that the accessory's specific operating limits are not documented in the linked booklet. Consider 6878 if a glass pitcher and explicitly named S-blade chopper are the more useful package. Move to 2142993 when a ten-cup bowl, reversible slice/shred disc or dedicated dough blade is central. If you need only a compact chopper, compare those hybrids with a standalone small-bowl machine that has an exact manual and a published ingredient chart; you may not need a blender base and pitcher at all. Verify the exact package code, included attachments and instruction booklet when shopping, because the family names alone do not identify all tools.
