Unique Features Of The Evolution Essential XTR   

InSinkErator's latest addition, "Evolution Essential XTR," comes with all the essential features premium waste disposals need to be the perfect unit for your home.  

Here are some unique features of the Evolution Essential XTR:  

Dura-Drive Technology 

This latest InSinkErator model has ¾ HP, ensuring unsurpassed performance. In addition, the unit has relatively higher grinding power, which means clogging or jamming won't occur while it operates.  

In addition to that, its motor is economical and uses 110 or 120 volts. It also comes with a sophisticated DuraDrive tech system, making the unit sturdy and dependable. Moreover, the motor runs quietly, and lifespan increases substantially as a result.  

SoundSeal Technology 

SoundSeal technology makes XTR amongst the quietest garbage disposers on the market. Thanks to this advanced technology, you won't hear much noise while the waste is grinding. 

In addition, the unit has a unique rubber cushion, also known as the "Anti-Vibration" mounting system, which scales between the sinks' opening and the bracket. This helps to minimize shaking by securing the sink during the entire grinding process. 

Evolution Essential XTR multi grind

Multi-Grind Technology 

InSinkErator's latest model has an innovative multi-grind technology that offers two phases of grinding. 

It cuts down food waste into tiny parts and prevents any jamming or clogging in the drainage pipes.  

Within the first phase, the scrap is chopped by moveable lugs, and in the next stage, the shreds of waste are moved through the holes and cut down into the tiniest particles by shearing movement.  

SinkTop Switch 

Unlike many garbage disposals that come with a wall switch, the InSinkErator Evolution Essential XTR garbage disposal has a SinkTop Switch, which is a substitute. It employs air pressure to switch your garbage disposer off and on.  

Quick-Lock Sink Mount 

InSinkErator's Quick-Lock sink mount makes the installation process a lot easier. All you've got to do is remove your existing appliance from underneath the sink and twist in your new one.  

Stainless Steel Grind Chamber 

The InSinkErator Evolution Essential XTR comes with a premium stainless-steel grind chamber, ensuring durability and attractiveness. Compared to galvanized steel, stainless steel is more reliable and durable. 

Evolution Essential XTR quick lock

Moreover, it's more resistant to corrosion caused by minerals and water. So, if you're purchasing this model, longevity is guaranteed.   

Warranty Period 

The unit offers a generous 6-year warranty. The warranty includes both in-home labor as well as mechanical costs. In case there's a breakdown, InSinkErator sends their professionals to fix or replace it.  


The Evolution Essential XTR comes with a handy rubber splash that keeps waste within the unit while it operates. Plus, you can use the stainless-steel plug to cover the sink opening, so kids can't insert toys or their fingers in it.  

Jam Buster Wrench 

The Jam Buster Wrench is a practical, quick metal tool explicitly used to free simple clogs or jams in garbage disposals. 

So, if you face any clog or jam, use the wrench to free your XTR. Remember, this tool only works on InSinkErator garbage disposals.
