These pet vacuums are always super popular, and at an under $150 price point, we don't expect the deal to last long.

The Shark Pet Pro cordless stick vacuum is just $144 at Walmart, down from the normal price of $249.99. That's a 42% discount.

Vacuums have come a long way from the cumbersome corded models of decades past, but they’re not exactly…cheap. Thankfully, we’ve spotted lots of early Black Friday vacuum deals on all sorts of models—from upright to robotic to hardwood-specific to pet-friendly—many of which we’ve written about before and have tested in our own homes.
