InSinkErator Evolution Compact Review

by Paul

I have a co-worker who was complaining about how small space he has under his kitchen sink and never thought of fitting a disposal under it. He lives with his wife and two children and he was telling me that there are already things under his kitchen sink and he does not have space to put a big unit there.

I told him about the smaller sized disposals like the Badger 5 from Insinkerator or the Waste King L-2600. But he was not satisfied because a he was looking for something more powerful to meet the need of his family yet smaller in size. So I suggested him a very compact garbage disposal, InSinkErator’s evolution Compact.

The InSinkErator Evolution Compact is one of the smallest garbage disposals one can ask for. If you are looking for the best garbage disposal within medium budget with high power performance that easily fit under your sink then this is the perfect disposal you can buy.

There are lots of reasons why I am suggesting this product. The main reason is it has all the features one can look for a good disposer with a good price. Let me tell you one by one.

  • 3/4 Horsepower Motor
  • 1725 RMP Speed
  • Best For Medium or Big Family

This continuous feed kitchen disposal has a ¾ horsepower Dura-Drive Motor containing a 2 stage grinding system. It is very powerful as the motor runs at a speed of 1725 rpm which is perfect for a medium or big family.

Your regular kitchen wastes like food leftovers, small bones, even the hard to grind wastes like celery or banana peels etc. will be easily ground up by this powerful motor in two stages.

In the first stage, it grinds up the wastage in small particles. After that, the leftover particles are forced through the GrindShear Ring for shearing into even finer pieces. See more specifications.

Safety Features

Auto Reverse
Grinding Technology

This kitchen disposal has an Auto Reverse Grind system significantly reduces that chance of jam. If a jam occurred anywhere inside the grinding chamber this system makes it automatically spin in reverse and unclog.

The Stainless steel grinding components lessen the possibility of rust and corrosion that can cause any internal breakage.

The Evolution compact garbage disposal is powerful enough to grind the food particles in smaller pieces, reduces the chance of jam and makes it a safer option for your sewage system.

Installation Process

Noise Levels - Is It Loud?

Insinkerator Evolution Compact 8

The noise level of this powerful grinding chamber is lower than most of the other garbage disposers available in the market. I would say that the noise level is whisper like in comparison to the other devices.

Not only that, I have found many people who praise this disposer as a very quiet one. Comparing to the old badger disposers, it’s about 50% to 60% quieter.

It also has two anti-vibration mounting systems. One is on the collar mounting made of rubber cushions, which reduces the transfer of noise and vibration from grinding chamber to the sink. Another is on tailpipe mounting. Both ensure least vibration and noise.

The only noise you are going to hear for few seconds is when you turn it on. Other than that it is significantly quieter than many other disposers.

Size of the Unit

compact garbage disposal 1

This unit is called compact because it features the size of the unit. So, the InSinkErator Evolution Compact contains the most compact size over power comparing the other products of kitchen disposal.

It has a dimension of 13 x 9.3 x 13 inches which is much lower than the other powerful units available in the market. Let me clear something, you may find disposers smaller than Evolution InSinkerator Compact, but none of those are as powerful as it in terms of grinding the wastage or not as quiet as it.

So, in terms of a smaller sizes unit, it is compact with powerful features and facilities.


4 Year In-Home Warranty

You purchase this unit with a 4 Year In-Home full service limited warranty and it will cover both mechanical parts and labor cost.

Reviews from Other Customers

The consumers say these two words for this unit, small and powerful and one of the most compact garbage disposals ever. The noise and vibration level is so low that impress most of the old disposer replacing consumers.

Performance wise this can compete with the most powerful kitchen disposal. People also love it for the anti-jamming technology that ensures safety and reduces the chance of internal jam significantly. Also, there are close to no complain about the installation by most of the consumers. See More reviews on Amazon.

The Good & The Bad


  • Compact for a medium or big sized house
  • Best for space concerned buyers
  • Powerful kitchen disposal with ¾ horsepower motor
  • Durable Stainless Steel grinding components
  • Anti-Jamming technology that automatically can reverse spin
  • Two stage grinding system ensures finer waste particles
  • Super easy instructed installation with Quick-Lock mounting system
  • Noise level is very low comparing the other powerful kitchen disposal


  • The drainage of water is slower because of this unit contains a quiet collar sink baffle.

Note - I have heard from many users being very annoyed over this problem. I also got a funny solution for it. Once I heard someone complaining about this to InSinkErator support and he got another modified baffle in exchange of his one from the support which allowed draining the water properly. So, if this baffling problem bothers you too much, simply call for InSinkErator’s support and make a solution.

Final Verdict

No products found.

I think this is a pretty good kitchen disposer for anyone looking for a compact garbage disposal. The price is comparatively higher than the Waste King Disposers. For example, you can have exactly same power motor but at a lower price but obviously, there will be difference in terms of features, durability and user experience. 

So I prefer to those who are looking for the best garbage disposal unit within reasonable budget and concerned about space in their kitchen, they can easily go with InSinkerator’s Evolution Compact. Get the best price on Amazon!

If you are looking for a garbage disposal with more power, you can go with the Waste King L-8000 Legend.
