Why Choose the InSinkErator Evolution Excel

The InSinkErator Evolution Excel is not an entry level garbage disposal. It boasts a 1.0 horsepower motor, which is among the most powerful in household garbage disposals. Making the Evolution Excel the perfect disposal for households that need to process a lot of food waste.

The stainless steel construction, and superior build quality, allows InSinkErator to offer an industry leading 7-year warranty which covers parts and in-home labor.

This garbage disposal has all the bells and whistles. But despite all of the features, you can probably handle the installation yourself. Especially if you're replacing an exisiting garbage disposal.

The InSinkErator Evolution Excel is the perfect purchase for a homeowner who is looking to upgrade their garbage disposal, yet doesn't want to worry about problems for years to come.  

Pros and Cons of the Evolution Excel


  • Worry Free - After you've installed the InSinkErator Evolution Excel, there's no need to worry about the "Can't Go Down the Garbage Disposal" items anymore! Chicken bones, coffee grounds, egg shells . . . there's not a food item that this machine can't handle.
  • Easy Installation - Installing the Evolution Excel couldn't be easier. It takes less than an hour to disconnect your old disposer and mount the new one using your existing hardware. 
  • Optional Power Cord - If you're replacing an old disposal, save yourself some money and use the same cord. But if you're installing the InSinkErator Evolution Excel where there wasn't a disposal before, you can order the model that includes the power cord.
  • In-Home Warranty - Buying a household appliance can be nerve-racking. However, the 7-year parts and labor warranty should help put your worries at ease. But, it's not just the length of the warranty that's comforting. The in-home warranty means that for those 7-years, if anything should go wrong, a certified technician will make a house call to assess and fix the problem.


  • Large Size - The powerful 1 HP motor, and all the bells and whistles, means that this is one of the largest garbage disposals on the market. Although, it should fit under nearly any sink, the 9" x 9" x 13" footprint may make storage space a bit tighter. You may just need to find a new place to store the box of trash bags.
  • Installation Could Pose a Challenge - Although installation is easy, the fact that the Evolution Excel weighs 26 pounds could be slightly challenging . . . especially if you are doing it by yourself. You'll need to lift the unit up to the mount that's located under the sink. This could put you in a precarious position.

SoundSeal® Technology

Under normal circumstances this disposal puts out a mere 25 decibels of volume. That's one-twentieth the volume of a standard vacuum cleaner. In fact, the Evolution Excel is our top choice when it comes to quiet garbage disposals. Read our article and review.

MultiGrind® Technology

Remember when we said you could put chicken bones down the InSinkErator Evolution Excel? MultiGrind® Technology makes doing so possible.

Most competitors, and even InSinkErator's alternative products, only offer a two-stage grinding system. This can limit what types of food and how much food the disposer can handle. Three stages of grinding allows the InSinkErator Evolution Excel to turn any food item into a pulp so it can safely travel thru your waste water plumbing.
