InSinkErator calls the Evolution Excel the garbage disposal for people who enjoy the very best in kitchen appliances. What they mean is, the InSinkErator Evolution Excel has all the best features that you could ever put in a garbage disposal. The most powerful motor, the strongest stainless steel components, the quietest installation, and the best anti-jam features.

The InSinkErator Evolution Excel has the following features:

  • Three stages of grind that will chew up food waste like no other.
  • Absolutely the quietest noise levels when in operation thanks to multi-layer insulation and a stainless steel housing.
  • Vibration-free when in operation.
  • 1.0 horsepower motor (the most powerful among garbage disposals).
  • Jam sensor that automatically increases torque when friction is sensed to prevent jams.
  • Auto-reverse function that automatically reverses grind direction to prevent jams.
  • 40-oz. capacity chamber that is made of stainless steel for added durability.
  • 7-year in-home limited warranty. For the entire warranty period, you will receive free house calls (including parts and labor) when your InSinkErator needs to be installed, repaired, or replaced. InSinkErator boasts a network of 1500 professionally trained service agents.
  • A sink mount that allows for easy installation and replacement.
  • Wall switch activation making it easy to operate.
  • Made in the USA.

Packed With Power

There is perhaps no other garbage disposal on the market that is packed with as much power as the InSinkErator Evolution Excel. First of all, it operates with a 1.0 horsepower motor which is the highest available motor speed among all garbage disposals. If that’s not enough, it has a unique three-stage grind system that will rip through the toughest food scraps. If that’s still not enough, its incredible sensor and auto-reverse function is smart enough to gauge friction to increase torque and/or reverse the grind so that nothing gets jammed. Basically, the InSinkErator Evolution Excel keeps your plumbing repair-free and provides top performance each time you use it.

7-year Warranty

InSinkErator warranty for its garbage disposals come with free in-home service. That means during the warranty period, you are entitled to free parts and labor by professionally trained service agents. If something ever goes wrong, just give them a call. The InSinkErator Evolution Excel itself comes with a 7-year warranty, which is the maximum among all InSinkErator models. The warranty is really important because even if it’s InSinkErator’s most expensive model, the performance and the service make it worth the buy.

InSinkErator Evolution Excel Customer Reviews

To find out how well the InSinkErator Evolution Excel actually works, we went through hundreds of customer reviews. This is a summary of those reviews. It will give you a full picture of what to expect when you purchase the Evolution Excel garbage disposal.

3x Grind

Power is one of the main things advertised on this garbage disposal, and does it ever deliver! Pork chop bones? No problem. Potato skins? Piece of cake. Corn husks? Get it in there. With the amount of power in this machine, customers said it was worth every penny in contrast to having the privilege of unclogging a sink from past disposals! Of course, there are still things you have to make sure you’re not putting into any garbage disposal, but the Excel gives you more flexibility as it has the power to chew up a lot.

Whisper Quiet

When shopping for a garbage disposal, some people prefer to go in store to test the noise level for themselves. Often hardware stores will have a few plugged in for you to try. Then most people go on Amazon to buy it because that’s where the savings (up to 50% off!) are (even the company sites don’t have these deep discounts). Most customers who have taken this route say they were sold on the InSinkErator Evolution Excel because it is whisper quiet – quieter than any other machine out there. This is thanks to its superior insulation. No noise is allowed to escape. The InSinkErator Evolution Excel would be “excel”lent for kitchens with an open floor plan, an eat-in kitchen, or a sleeping baby.

Stainless Steel Durability

As a top-of-the-line product, the InSinkErator Evolution Excel is built with high-quality stainless steel materials. This adds to the durability of the garbage disposal, but also gives it that beautiful finish.

Should you buy the InSinkErator Evolution Excel?

You get what you pay for when buying the Excel. It’s the only InSinkErator with a 1.0 horsepower motor, triple grind stages, jam sensor and auto-reverse function, stainless steel construction inside and out, and 7-year in-house warranty. Most people may not have considered this garbage disposal as their first choice – after all it isn’t the cheapest on the market – but considering its capability and the fact that they use their disposal every day, it’s worth the money. In fact, many were happy they bit the bullet and were pleased to avoid potential plumbing problems. Tip: purchase the InSinkErator Evolution Excel from Amazon to save 50% off its manufacturer’s price.


    1. It’s got good grind power so you would be fine. But do take the necessary precautions (for example maintenance) to avoid damaging your septic system.

      1. I have a septic system at my cottage in Ontario and want to buy either the Evolution Excel or the Evolution Septic Assist. I like the features of the Excel as it seems to allow more types of vegetables to be ground and less prone to jamming. However, the Septic Assist has the enzymes to help with the septic system. Can you just add enzymes down the drain with the Excel and how often? Or does the Septic Assist also grind celery, onions, artichokes, etc. sufficiently? Which would you recommend? Thank you.

        1. Hi! Apologies for the late reply. The Septic Assist will be more beneficial for a septic system but the Excel is the more powerful of the two… You mention an interesting idea! There shouldn’t be any problems with adding the enzymes down the drain… Just make sure you dilute it with water. Each time the Septic Assist is turned on it injects about 1/3 teaspoon of the liquid… so you can probably pour that amount down the drain while diluting it with water… We’ve never done it so maybe it’s better to contact InSinkErator to ask for their opinions on this! On the other hand the Septic Assist shouldn’t have problems with grinding vegetables and peels. So it may be the better choice after all!

  1. Well said. I’m a pro kitchen designer and remodeler who once found whole black beans after snaking out a clog in my own home! Never again, and for only an extra $150. When I see people who rarely cook spend $12,000 on a range and $14,000 on a fridge, then balk at a $350 disposal, I sometimes laugh. Never has the expression ‘out of sight, out of mind’ been more accurate.
    Buy a faucet 3x the price you had planned on while you’re at it. It’s the most frequently running appliance in your home. A superior faucet will likely never need repair for decades.
