InSinkErator Evolution Pro 750 vs 880 LT – A Detailed Comparison

Choosing the right garbage disposal can make a noticeable difference in how smoothly your kitchen functions. Both the InSinkErator Evolution Pro 750 and InSinkErator Evolution Pro 880 LT come from the brand’s premium lineup and share many of the same strengths—quiet performance, durable components, and multi-stage grinding.

However, they are built for slightly different types of kitchens and households. While the Pro 750 focuses on compact power and reliable everyday performance, the Pro 880 LT takes things a step further with stronger horsepower, ultra-quiet operation, and a longer warranty.

This guide walks you through each model’s features, real-world performance, and value so you can confidently choose the one that fits your needs.

InSinkErator Evolution Pro 750, 3/4 HP Garbage Disposal

The InSinkErator Evolution Pro 750 is built for homeowners who want powerful performance without sacrificing cabinet space or quiet operation. With a 3/4 HP induction motor, 2-stage MultiGrind technology, and SoundSeal insulation, it handles everyday food scraps easily while keeping noise to a minimum.

Its compact body makes it a great match for small kitchens or tight under-sink areas, and the included power cord makes installation simpler than many higher-end models.

Where some disposals struggle with fibrous scraps like celery or melon rinds, the Pro 750’s multi-stage grinding system breaks them down efficiently, reducing the risk of clogs and jams. And since it’s part of InSinkErator’s Pro Series, you also get a Quiet Collar baffle that minimizes vibration and splash while dampening sound.

If you want strong performance, a quieter kitchen, and a model that doesn’t demand much space, the Pro 750 is a dependable fit for the average household.

InSinkErator Evolution Pro 880 LT, 7/8 HP Garbage Disposal

The InSinkErator Evolution Pro 880 LT takes everything the Pro 750 offers and ramps it up. With a more powerful 7/8 HP induction motor, 2-stage MultiGrind, and an upgraded SoundSeal system, this unit is designed for homeowners who want top-tier performance paired with ultra-quiet operation.

What makes it stand out is the Auto-Reverse technology, which helps prevent jams before they happen by reversing direction when resistance is detected. This not only protects the motor but ensures smoother, more efficient grinding over time.

Despite the stronger motor, the footprint remains compact, making it suitable for smaller cabinet spaces. You also get high-quality stainless steel components and a 10-year in-home warranty, giving you longer protection than the Pro 750.

For families that cook often or generate heavier food waste, the Pro 880 LT delivers the extra power and durability needed to keep up.

InSinkErator Evolution Pro 750 vs Evolution Pro 880 LT: In-Depth Comparison

Motor Performance & Grinding Power

The Pro 750 delivers strong everyday performance with its 3/4 HP induction motor, easily handling common kitchen scraps. The 2-stage MultiGrind system breaks waste down twice, helping prevent clogs and improving drainage.

The Pro 880 LT steps up with a 7/8 HP motor, giving it more torque and smoother handling of tougher waste like fibrous vegetables and small bones. Combined with Auto-Reverse, it’s far better at resisting jams and maintaining consistent grinding speed under load.

If you cook often or deal with heavier food waste, the 880 LT feels more effortless overall.

Noise Levels & User Comfort

Both units use SoundSeal technology, but the 880 LT takes noise reduction a little further with more advanced anti-vibration mounts and internal insulation.

The Pro 750 is quiet compared to standard models—good enough for everyday use—but the Pro 880 LT operates at a level where you can talk, watch TV, or even take a phone call without raising your voice.

If peace and quiet matter, especially in open-concept kitchens, the 880 LT has a clear advantage.

Installation & Space Requirements

Both models share a compact, space-saving footprint and fit comfortably under most sinks.

The Pro 750 is slightly easier for DIY installation thanks to its included power cord and Quick Lock mount. The Pro 880 LT may require a separate cord depending on the package, but the mounting system remains user-friendly.

In terms of size, both units measure roughly the same and shouldn’t create any clearance issues in standard cabinets.

Durability & Warranty

Durability is a strong point for both disposals, thanks to stainless steel grinding components and sturdy internal construction.

But their warranties differ significantly:

• Pro 750: 6-year in-home service warranty
• Pro 880 LT: 10-year in-home service warranty

If long-term protection is important, the Pro 880 LT gives you four more years of worry-free coverage.

Price & Value

The Pro 750 generally sits in a mid-range price bracket, offering great performance for the cost, especially considering the included power cord.

The Pro 880 LT is priced higher, but the added power, quieter operation, Auto-Reverse system, and longer warranty help justify the difference for households that demand more from their disposal.
