Dimensions

The main difference between Waste King 9940 vs the 9950 is the dimensions. The 9940 has a height of 13.5 inches and a maximum width of 8 inches whereas the 9950 disposer is a bit bigger with a height of 14.5 inches and a width of 8.5 inches.

The Waste King 9950 model seems to have more grinding chamber capacity since it is bigger in size even though the motor used in both models are the same.

The 9940 disposer is also lighter; it weighs 9.4lbs whereas the 9950 weighs 12.83lbs.

Performance

Both garbage disposals share the same motor. However, the grind chamber capacity of the 9940 is less than that of the 9950 disposal unit. This means that Waste King 9940 has more power per pound of food wastes. This makes its performance marginally better than that of 9950. But since both disposals are continuous feed type, I don’t know how relevant this comparison is, it is probably nothing. So for the sake of comparison lets say the performance of 9940 is slightly better than that of 9950.

Warranty

Another difference between the Waste King 9940 and 9950 is the warranty. The 9940 garbage disposal is covered under a limited warranty of 8-years whereas the 9950 is under a 10-year warranty. But if you are using them for commercial purposes the warranty coverage for both models is only 1-year.

If you ask me why there is this difference in warranty even though both disposals use the same motor and have the same material quality, I don’t know the answer.

Price

Waste King 9950 is usually priced slightly higher than the 9940 garbage disposal justly so since it is slightly bigger. The prices fluctuate on special occasions and for discount sales but usually, the difference in the pricing is no more than 20 bucks.

Waste King 9940 vs 9950 – Similarities

There are plenty of similarities between the 9940 and the 9950 garbage disposals.

Both 9940 and 9950 garbage disposals are run by the same 3/4 HP, 2700 RPM permanent magnet type motor.

Both models come with some basic noise insulation.

Both have preinstalled power cords, and both models use 3-bolt mounting assemblies.

Both 9940 and 9950 disposal units have the same build quality; their grinding components are made of Stainless steel and their grinding chambers are made of corrosion-resistant polymer.

Their sink flanges are made of Stainless steel with Stainless steel finish.

They come with front-facing, manual reset buttons. Both have a similar design and paint job as well.

Which is a better garbage disposal-9940 or 9950?

Both are so similar, however, Waste King 9950 comes with a 10 year warranty; 2 more years than the 9940 model. I always consider a 2-year more warranty at the expense of 20 bucks a good deal, so I will definitely go for 9950 over 9940.

But if the space under your kitchen sink is low maybe you will have to go for the 9940 disposal unit since it is 1 inch shorter in height. If you have ample space there, then by all means, go for the Waste King 9950 garbage disposal.

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.
