Autoreverse feature

Evolution Pro 750 Comes With AutoReverse Technology But Evolution Compact Doesn’t Have It.

AutoReverse is a proprietary technology by InSinkErator where a garbage disposal automatically changes the direction of rotation of its blades each time the disposal is started. This makes sure that the blades are worn evenly, and this alternative rotation also helps to reduce jams. Evolution Pro garbage disposal uses this technology, while Evolution Compact units don’t.


Both Evolution Compact and Pro 750 garbage disposals are quiet. But Pro 750 is a bit quieter than the other. This is due to the presence of an extra layer of insulation around the Pro 750 disposer. This technology, which involves this extra insulation, is called SoundLimiter technology, and it is another proprietary technology of InSinkErator.

InSinkErator covers Pro 750 garbage disposal under a 9-year warranty while that for Evolution Compact is only 8-years. The warranty periods of garbage disposals change from time to time, the Compact model had only a 5-year warranty a few years ago. So this difference is bound to change however, now Pro 750 is a better model in terms of the warranty.

This warranty for both disposer models is an in-home warranty that covers labor and parts. While under this warranty period, the technician will come to your home for the repair or replacement of the disposal, and if that doesn’t work the company will refund the full purchase amount.

Just like for all other InSinkErator disposals, this long terms warranty is only for domestic uses.

Anti-microbial sink baffle

A sink baffle is that black rubber thing situated inside the drain hole of the kitchen sink, which forms the top part of the garbage disposal. The sink baffles of both Pro 750 and Compact disposals are designed to muffle the sound of grinding.

However, the sink baffles that come with 750 Pro disposal models have an anti-microbial coating that prevents the growth of microbes like bacteria to a large extent.


Pro 750 is usually more costly than Evolution Compact garbage disposal. I say ‘usually’ because the prices of these garbage disposals change from time to time especially when it comes to special discounts. So I recommend you to check the current pricing before you buy.

I believe that the higher price of Pro 750 is well justified because it has a longer warranty, better insulation, and AutoReverse technology when compared to Evolution Compact. However, Evolution Compact gives you more value for the money as these extra features aren’t that important when it comes to your daily use of a garbage disposal.

My Opinion: Pro 750 or Evolution Compact

In my opinion, Evolution Compact provides more value for money, and hence it is a better choice over Pro 750.

While Pro 750 has many more features than Evolution Compact, they are not much life-changing when it comes to daily usage. Both models are quiet and powerful and are a good choice for a household of 3 to 5 people, and even though Pro 750 is slightly better than Compact in some areas, I prefer Evolution Compact for the before said reason.
