Want more deals? Visit CNN Underscored’s Guide to Prime Day for wall-to-wall coverage of the best discounts to be found during Amazon’s massive sale.

There are a lot of random, unnecessary things you can buy during Amazon Prime Day (like those kitchen gadgets you’ll never actually use or funny socks you definitely didn’t need), but year after year, one of the most practical purchases you can make during the two-day sale is a new vacuum cleaner.

But you don’t want to buy just any discounted vacuum cleaner. Here at CNN Underscored, our editors thoroughly test all kinds of vacuums — from cordless stick models to (almost) hands-free robot vacs — to help you find the very best one for your needs. And as a home editor, I’ve also logged plenty of hours throughout my career pouring dirt, rice and wig hair on the floor to see which vacuums pass the test.

So, to help you figure out which vacuums are actually worth buying during October’s Prime Big Deal Days, I’ve rounded up the very best deals. Though the sale is almost over, there’s still time to buy the perfect vacuum for all your cleaning needs. Shop the deals below and save big during these final hours of Amazon’s October Prime Day.

Amazon Prime Day upright vacuum deals

Not only is the Dyson Ball Animal 3 extremely discounted for the October Prime Day, but it also comes with an extra attachment for dusting — making it an even sweeter deal.

This pick from Shark — the brand behind our best-tested upright vacuum — is currently 40% off. Even though it was $20 cheaper last Prime Day, we still think it's a good deal at $120.

Lowest Price

With a HEPA filter, an odor-eliminating filter and pet-friendly attachments, this upright vacuum from Bissell is a score for those with furry friends at home.

Amazon Prime Day cordless stick vacuum deals

Bissell's vacuums are known for being great on pet hair, and this cordless stick model hasn't been this cheap since April.

At $200 off, we haven't seen this vacuum at this price since last Prime Day. It comes with two removable batteries so you can vacuum for up to 120 minutes without stopping to let it charge.

Dyson vacuums are expensive, so it's always worth waiting until they go on sale. At $180 off right now, we think it's a good time to splurge.

Amazon Prime Day robot vacuum deals

Our former top pick for the best robot vacuum, the iRobot Roomba j7+ is still a solid choice. And right now, the self-emptying model is 50% off.

Those on an even tighter budget these days will appreciate that the best affordable robot vacuum we've tested is even cheaper during October Prime Day.
