Shark navigator series include a few models, and some of their titles are very similar, these may confuse consumers. Generally speaking, the similar titles indicate that there is no big difference between them. The last letter/letters in the name indicate they are made for different merchants such as Amazon and Walmart, however, these units usually are the same machine except for few tiny difference such as attachments they comes with and their colors.

So, what is the difference between Shark NV22 and NV22L?

For the first thing, the attachments they come with might be different, I think it depends on where you buy the vacuum cleaner.
On Shark official site sharkclean.com. it states the NV22 have the 24″ Crevice Tool and Premium Pet Power Brush, but at Walmart.com the NV22 does not have these 2 tools. It just includes a smaller Crevice Tool and a smaller Dusting Brush.
The Shark NV22L might come with a 5.5″ Crevice Tool, Premium Pet Power Brush, dusting brush; or all of the tools mentioned above: 5.5″ Crevice Tool, 24″ Crevice Tool, Premium Pet Power Brush, dusting brush. Depends on where you buy.

Secondly, about the color.
You can find that the NV22 is blue at Walmart.com, but at sharkclean.com, it is lavender.
While the NV22L is lavender. So, I think the “L” in the title means Lavender.

Except for the above mentioned points, they are the same unit.
