Product Overview
The Ninja Professional Plus Blender DUO with Auto-iQ BN751 is a countertop blender designed for both full-size and single-serving blending. It combines a 72-ounce Total Crushing pitcher with two 24-ounce single-serve cups, allowing the same motor base to prepare larger batches or individual drinks.
The blender uses a 1,200-watt operating motor rated at 1,400 peak watts. The full-size pitcher works with Ninja’s removable Stacked Blade Assembly, while the single-serve cups use a separate Pro Extractor Blades Assembly. The pitcher has a maximum liquid capacity of 64 ounces despite its 72-ounce overall container capacity.
Three Auto-iQ programs automate selected blending tasks through timed combinations of blending, pulsing, and pauses. Manual controls provide additional adjustment when an automatic cycle is not required. The system is intended for foods and cold beverages such as smoothies, frozen drinks, crushed-ice preparations, dips, sauces, and blended fruit or vegetable drinks. Ninja specifies that hot liquids, dry grinding, and operation beyond marked fill limits are not supported uses. Removable food-contact attachments are BPA-free and dishwasher safe.

Common Uses
- Preparing fruit and vegetable smoothies.
- Crushing ice for cold beverages.
- Blending frozen fruit and other frozen ingredients.
- Preparing blended frozen drinks.
- Making individual smoothies in the single-serve cups.
- Preparing larger batches in the full-size pitcher.
- Mixing cold dips, dressings, and sauces.
- Blending cold fruit and vegetable drinks.
Maintenance and Care
The motor base should be unplugged before cleaning, assembly, or disassembly. It should be wiped with a clean cloth and must not be immersed in water or sprayed directly with liquid.
The pitcher, cups, lids, and blade assemblies are dishwasher safe. Ninja recommends placing these removable components on the top rack of the dishwasher.
The blade assemblies are removable and extremely sharp. They should be handled only by the areas specified in the owner’s guide rather than by the cutting edges.
Food residue should not be allowed to dry around the blades, lids, seals, or threaded cup connections. Components should be thoroughly dried before storage or reassembly.
Safety Information
The BN751 is intended for indoor household use. It should operate on a dry, level surface and should be disconnected from electrical power when not in use or before components are removed.
Hot liquids must not be processed in this blender. Heated liquids can produce pressure and steam inside the containers, creating a risk of burns or unintended release of contents.
The Stacked Blade Assembly and Pro Extractor Blades Assembly contain exposed sharp edges. The blades should not be touched directly and must never be installed on the motor base without their corresponding container.
Containers must not be filled above their marked maximum fill or maximum liquid lines. The appliance should also not be operated with an empty container.
Ninja instructs users not to perform dry grinding with either the pitcher and Stacked Blade Assembly or the single-serve cup and Pro Extractor Blades Assembly.
If the motor overheats, an internal thermal protection system can temporarily stop operation. Ninja instructs users to unplug the blender and allow it to cool for approximately 30 minutes before attempting to use it again.

Product History
The BN751 belongs to Ninja’s Professional Plus Blender DUO series, which expanded the company’s full-size blender format by combining a large pitcher with personal blending cups. The series followed earlier Professional Blender DUO products while introducing updated controls and Auto-iQ programming.
Within Ninja’s related lineup, the BN701 Professional Plus Blender uses a similar full-size pitcher format without the same DUO single-serve configuration. The BN801 Professional Plus Kitchen System expands the platform further by adding food-processing components.
The BN751 remains supported by SharkNinja through the BN750 Series documentation and replacement-parts system. Accessories should be matched by documented model compatibility rather than appearance alone because similar Ninja containers may use different locking interfaces.

Compatibility
The BN751 works with the full-size pitcher and personal cups designed for compatible Ninja Professional Plus Blender DUO models. Replacement components should be verified against the BN750 Series or BN751 compatibility information before use.
Ninja lists compatible replacement parts that include a 72-ounce Total Crushing pitcher and lid, 24-ounce blending cups, Total Crushing Stacked Blade Assembly, and compatible BN751 motor-base components.
The personal cups require the Pro Extractor Blades Assembly for blending. The Stacked Blade Assembly is instead designed for the large pitcher and should not be interchanged with the personal-cup blade system.
The appliance is intended for a 120-volt electrical supply. It should not be connected to incompatible voltage systems without equipment specifically designed and approved for the appliance.
Frequently Asked Questions
What is the difference between the BN751 and a standard Ninja Professional Plus blender?
The BN751 adds personal blending capability through dedicated single-serve cups and a separate Pro Extractor Blades Assembly. Standard full-size configurations may include only the main pitcher.
Is the pitcher really 72 ounces?
The physical pitcher is rated at 72 ounces. However, Ninja specifies a lower 64-ounce maximum liquid capacity, which should not be exceeded during liquid blending.
Can the BN751 make single servings?
Yes. Two dedicated single-serve cups are included and attach to the motor base through the Pro Extractor Blades Assembly.
Can drinks be stored with the blade attached?
No. Ninja instructs users to remove the blade assembly after blending. The spout lid should be used when covering a single-serve cup for drinking or temporary storage.
Can the BN751 blend hot soup?
No. The owner’s guide specifically prohibits blending hot liquids because pressure and steam can accumulate inside the container.
Can it grind coffee beans or other dry ingredients?
No. Ninja instructs users not to perform dry grinding with the pitcher or personal blending cup systems supplied with this model.
Can the pitcher crush ice?
Yes. The large pitcher and Stacked Blade Assembly are designed for blending ice and frozen ingredients when used according to the owner’s instructions.
What does Auto-iQ do?
Auto-iQ runs predetermined patterns of blending, pulsing, speed changes, and pauses. The selected program stops automatically when its programmed cycle finishes.
Can the blender also be controlled manually?
Yes. Manual programs allow the user to select continuous blending speeds or pulse the ingredients rather than using an automatic cycle.
Are the cups BPA-free?
Yes. Ninja identifies the removable attachments supplied with the BN751 as BPA-free.
Are the blender parts dishwasher safe?
The removable containers, lids, and blade assemblies are dishwasher safe. Ninja recommends placing these components on the top dishwasher rack.
Can the motor base go in the dishwasher?
No. The motor base contains electrical components and should not be immersed, placed in a dishwasher, or sprayed with water.
Why will the blender not start after becoming hot?
The motor may have activated its thermal protection system. Ninja instructs users to unplug the machine and allow it to cool for about 30 minutes before restarting it.
Do all Ninja 72-ounce pitchers fit the BN751?
No compatibility should be assumed based solely on stated capacity. Locking tabs, lid designs, drive connections, and blade assemblies can vary among Ninja model families.
Does the blender require installation?
No permanent installation is required. Before first use, food-contact parts should be washed, dried, and assembled according to the owner’s guide.
How should the blade assembly be removed?
The Stacked Blade Assembly should be handled from the top of its shaft, while the personal-cup blade assembly should be handled around its outer base. Direct contact with the cutting edges should be avoided.
What warranty applies to the BN751?
SharkNinja lists a one-year limited warranty for this model. Coverage conditions, exclusions, and claim procedures are governed by the applicable warranty terms.
Buying Considerations
The BN751 includes both a large pitcher and personal cups, so it occupies more storage space than a dedicated personal blender. The motor base and assembled pitcher also require sufficient vertical clearance on a countertop.
The 72-ounce pitcher designation should not be interpreted as permission to blend 72 ounces of liquid. The documented maximum liquid capacity is 64 ounces.
The appliance is intended for cold and room-temperature blending rather than hot-liquid processing. People who routinely prepare hot soups should distinguish this design from appliances specifically rated for heated ingredients.
Replacement accessories should be selected by model compatibility. Ninja has produced several blender systems with similar-looking pitchers, cups, lids, and blade assemblies that are not necessarily interchangeable.
The personal cups provide smaller-batch capability, but the Pro Extractor Blades Assembly must be removed before the cups are used with their drinking lids.
Customer Feedback Summary
This section is a generalized summary of recurring publicly available customer feedback and does not represent verified product specifications. Positive comments frequently focus on ice-crushing performance, smoothie preparation, the availability of both pitcher and personal-cup formats, and the convenience of preset blending cycles.
Users commonly describe the single-serve cups as useful when preparing one beverage without cleaning the full-size pitcher. The large pitcher is more often discussed for larger batches of smoothies, frozen beverages, sauces, or similar mixtures.
Recurring limitations include operating noise, the vertical height of the pitcher and motor-base combination, and the amount of cleaning required around the removable blade assemblies. Some users also find the blade assemblies more cumbersome to handle than fixed-blade blender jars.
Owner reports occasionally mention container wear, lid or locking difficulties, leaks, blade-component wear, or motor problems after extended use. These experiences vary by unit, maintenance, loading practices, ingredient type, and operating history.
