InSinkErator Evolution Pro 1100XL Review

Pro 1100XL is a premium garbage disposal in the Evolution series of InSinkErator. It comes with all the top of the line technologies, and an extra 0.1 horsepower than their evergreen best model; Evolution Excel.

To be frank, the Pro 1100XL is one step ahead of the Evolution Excel in some aspects so I may need to declare it as the best of all disposers, but we are not there yet.

Power & Performance

Evolution Pro 1100XL is powered by a 1.1 HP DuraDrive induction motor. It is a slow speed motor that runs at 1725 RPM which is the standard speed for all garbage disposals by InSinkErator. It uses Mult-Grinding, a proprietory technology by InSinkErator where the food wastes are ground through multiple stages. The Pro 1100XL uses a 3-stage grinding system which, in this case, is called MultiGring Plus technology because it also uses a JamSensor in addition to the extra grinding stages.

The purpose of the JamSensor (which is another patented technology name) is to detect the possibility of jams and increase the torque of the motor up to 500% giving it enough power to cut through.

This disposer also features ‘AutoReverse’ technology which reverses the direction of rotation of its blades in case the disposer is stuck. Jams can happen at times and this AutoReverse feature helps to unclog any obstructions. Also, each time you start the disposal it rotates in the direction opposite to its previous use, for eg: if it was running in the clockwise direction when you first used it, then it was running in the anticlockwise direction the next time you turned it on.

Pro 1100XL is a continuous feed type disposal, and it has a chamber capacity of 40oz.

Build quality

This is a premium garbage disposal so it is built to the highest standard. It uses stainless steel grinding components as well as a stainless steel grinding chamber. Stainless steel is great at withstanding corrosion, it makes the unit expensive but you can be sure it will last longer than cheaper ones. Its sink flange is also made of stainless steel.

This disposal unit uses a 3-bolt mount which is sturdier than the EZ type mount. The unit comes with a black and stainless steel finish. In many ways, it resembles the Evolution Excel.

Noise

Pro 1100XL is an ultra-quiet garbage disposal thanks to the InSinkErator’s SoundSeal Plus technology. This disposal unit comes with layers of insulation around its housing. In addition, it comes with anti-vibration sink mounts. As you know a good percentage of the noise from a garbage disposal us due to vibration, these anti-vibration mounts eliminate a good portion of it.

Space & Installation

Pro 1100XL is a compact garbage disposal. With 13 inches in height and a width of 9 inches, it can fit into almost any under-sink spaces (Here is a list of all compact garbage disposals for your reference)

As mentioned before it uses a 3-bolt mount. With its QuickLock mechanism (a twist and lock mechanism) you can install this disposal without much effort. I also suggest using a garbage disposal installation tool if you are doing this alone because the 3-bolt mount is not easy to install if you are all by yourself. I mean it is not that complicated however you will need some additional hands to hold the disposal in position during the installation.

Price & Warranty

The Pro 1100XL is a premium range disposal so it is definitely pricey. Regarding the warranty it comes with a 12-year ‘we come to home’ warranty which is pretty good.

My thoughts

Pro 1100Xl is a relatively new disposal but it is building its customer base really fast. It is better than the Evolution Excel in some aspects as well so this is one model you should definitely consider if you are looking for a top-notch garbage disposal.

I also wrote a quick article comparing Evolution Excel and Pro 1100XL, you may find it interesting.

A few years back I bought a garbage disposal for the first time in my life. And the buying experience wasn't good. There were lots of models in the market, and I was not sure about which one to buy. They all looked the same to me. So once I went through the experience I started this blog to randomly write things about garbage disposals. Then I got really interested in the subject and started to write comparisons of very similar garbage disposals with each other. A lot of my readers find them very useful in making the right buying choice. I hope it helps you too.
