InSinkErator Pro 750 vs Evolution Compact: A Comparison

InSinkErator Evolution Pro 750 and Evolution Compact are two garbage disposal models that are very hard to distinguish at first look. hey have very similar specifications and they look alike. How are they different?

One main difference between Pro 750 and Evolution Compact is that Pro 750 comes with AutoReverse technology which automatically changes the direction of a garbage disposal to reduce jams. Also, Pro 750 is quieter than Evolution Compact garbage disposal.

There are a few more differences between these two garbage disposal models which will be detailed in the rest of this article.

Differences between InSinkErator Pro 750 and Evolution Compact

Here are the differences between InSinkErator Pro 750 and Evolution Compact;

  • Evolution Pro 750 comes with AutoReverse technology whereas Evolution Compact doesn’t have it
  • Pro 750 is quieter than Evolution Compact
  • Pro 750 is covered under a 9-year warranty whereas Evolution Compact is covered under an 8-year warranty.
  • The sink baffle of Pro 750 comes with anti-microbial material whereas that of Evolution Compact doesn’t have it.
  • Pro 750 is usually priced higher than Evolution Compact

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.

Pro 750 is quieter than Evolution Compact

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.

Pro 750 is covered under a 9-year warranty whereas Evolution Compact is covered under an 8-year warranty

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.

The sink baffle of Pro 750 comes with anti-microbial material whereas that of Evolution Compact doesn’t have it.

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 which prevents the growth of microbes like bacteria to a large extent.

Pro 750 is usually priced higher than Evolution Compact

Pro 750 is usually 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.

Performance

The performance of both Evolution Compact and Pro 750 are on par with each other. Both these machines are powered by the same 3/4 HP dura Drive induction motor. Both of them use Multi-Grind technology; here food wastes undergo two stages of grinding which makes the final ground particles smaller so they can be disposed of without clogging the pipes. These garbage disposals can grind tough food materials including chicken bones thanks to the combined effect of the 2-stage grinding and the 3/4 HP motor. This is handy since standard garbage disposals cannot handle such food wastes.

These two are continuous feed type garbage disposals where the food wastes can be fed into the unit continuously. They both have a grinding chamber size of 34.6 oz which gives plenty of room to dispose of food wastes from a large family.

Installation

The installation of both Evolution Compact and Pro 750 follow the same procedure. They use the same 3-bolt assembly for connecting them to the sinks. Since both disposers have the exact same dimensions they can be swapped with each other without making any changes to the plumbing.

Both these garbage disposals models can be bought with pre-installed power cords which makes the installation much easy for amateur DIYers.

Here is a video showing how an InSinkErator disposal installed, this is the same for all disposer models;

Build quality & warranty

Both Pro 750 and Compact belong to the ‘Evolution’ series of InSinkErator garbage disposals. They are premium disposals that are crammed with all the advanced features one such machine can have. So the build quality of both Pro 750 and Compact are top-notch. Both of them are constructed with high-quality alloy stainless steel with leak guard liner which prevents leaking from these units. The grinding components are also made of stainless steel which ensures that they will run smoothly without rusting for a long time.

As mentioned before both Pro 750 and Compact are covered by long warranties which are not available to standard disposal models. They come with 9-year and 8-year in-home warranties respectively.

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.
