InSinkErator Evolution Pro 750 vs 880 LT – A Detailed Comparison
The InSinkErator Pro 750 and Pro 880 LT come from InSinkErator’s professional-grade lineup. In this InSinkErator Evolution Pro 750 vs 880 LT comparison, we look at how these two models share the same engineering DNA — Dura-Drive induction motors, 2-stage MultiGrind, SoundSeal noise reduction, and stainless steel components — yet differ in power, noise levels, features, and warranty.
Important: Both models are discontinued by InSinkErator. They are still available through some online retailers while stock lasts, but once gone, they will not be restocked. If you find one at a good price, it is still a solid purchase — the technology is proven and parts remain available.

Key Differences
Power: The 880 LT’s 7/8 HP motor delivers more torque than the 750’s 3/4 HP. This means smoother handling of tougher scraps — fibrous vegetables, small bones, and heavier loads — with less strain on the motor.
Noise: Both use SoundSeal, but the 880 LT adds more advanced anti-vibration mounts. In practice, the 880 LT is noticeably quieter. You can take a phone call while it runs without raising your voice.
Jam prevention: The 880 LT includes Auto-Reverse — when it detects resistance, it reverses direction to clear the blockage automatically. The Pro 750 does not have this feature.
Warranty: 10 years vs 6 years. Four extra years of in-home service coverage is a significant advantage for the 880 LT.
Power cord: The Pro 750 includes one. The 880 LT may or may not (depends on the specific retailer listing).
What They Share
- Dura-Drive induction motor technology
- 2-stage MultiGrind grinding system
- SoundSeal noise reduction
- Stainless steel grind components
- Compact, space-saving design
- InSinkErator 3-bolt mounting
If you like the Pro series engineering but want something currently in production, the closest alternatives are the Evolution Compact (3/4 HP) and Evolution Advanced (1 HP).
Conclusion
Buy the Pro 750 if you want solid 3/4 HP Pro Series performance with an included power cord at a mid-range price. Best for moderate-use households.
Buy the Pro 880 LT if you want more power, quieter operation, Auto-Reverse jam protection, and a 10-year warranty. Best for heavy-use households that cook daily.
Skip both if stock is unavailable or overpriced — the current Evolution lineup offers equivalent or better performance.
