Key Differences: Shark AX951 vs NV801

As you can see in the chart above, there are several similarities that these two Shark vacuums share. Also, there are differences that may be crucial to your decision as to which one you should pick. Here’s a list.

Dust Cup Capacity

Based on data available online, we found that the Shark AX951 has a larger dust cup. It can contain 1.5 quarts of dust, dirt, and other dry particles. In comparison, the NV801 has a cup whose capacity is pegged at 0.9 dry quarts.

Colors Available

With the Shark AX951, you’ll have two colors to choose from; with the Shark NV801, you’ll have three.

Accessories Included

You’ll have more accessories/extras included if you purchase a Shark AX951. Both boxes will come with a multiflex under appliance, a pet multi-tool, and a duster crevice, but with the Shark AX951, expect two more: an accessory bag and an Anti-Allergen Dust Brush.


Look at the bottom part of the chart and you’ll clearly see that the NV801 is not equipped with two features that you can find in the Shark AX951; one, the Active-Glide Technology; second, Noise Reduction Technology.

What do these features do?

When cleaning the floor, you want a consistent, smooth gliding action because interruptions caused by “bumpy” cleaners are such an inconvenience. This is where the Active-Glide Technology comes in, making sure that the Shark AX951 provies you with smooth maneuverability during the cleaning process.

Neighbors can’t stand the noise coming from your vacuum cleaner. Although the Shark AX951 is not devoid of noise, its Noise Reduction Technology helps in softening the pitchy sound that comes out of it.

LED Lights

Thanks to LED lights, you can breeze through dark spaces just fine. The Shark AX951 has LED lights on both its nozzle and handle. On the other hand, the NV801 has LED lights only on its nozzle.
