Prime Day may be Amazon’s made-up retail holiday, but it also happens to play host to some of the best sales and deals you’ll see on products all year.

This year, Prime Day 2019 will take place on July 15-16, 2019. It will be live for 48 hours, a departure from last year’s 36 hours of deals.

Every year, the Insider Picks team sorts through thousands of deals in real time on Prime Day to share the top 1% of discounts buried in an avalanche of thousands. But once Prime Day is over, it’s always fun to go back and see what deals resonated most with Business Insider readers.

1. iRobot Roomba 671

iRobot Roomba 671 Robot Vacuum with Wi-Fi Connectivity, Works with Alexa, $289.99 [Last year’s Prime Day price, $229.99] 

The Roomba 671 was no surprise at all given that it was at its lowest price ever. This intelligent robot vacuum uses a proprietary three-stage system to clean everything from fine particulates — like dust — to larger debris like sand, hair, and sizeable crumbs. It’s Alexa-enabled, so you can control it with your voice or with the available smartphone app. You can read more about the vacuum here.

2. Audible membership

Audible membership, first 3 months $4.95 per month, or get an Echo Dot for $0.99 when you sing up for an annual membership [Last year’s Prime Day promotion: first 3 months for $4.95 per month]

For last year’s Prime Day, Amazon discounted its Audible service by 66%, meaning new subscribers could get four months at $4.95 per month rather than $14.95. Audible gives you access to one audiobook credit per month (which never expire) and 30% off additional audiobooks. 

3. Kindle Unlimited membership

Kindle Unlimited membership, free 3 months free [Last year’s Prime Day promotion: first 3 months for $1] 

Among our own readers, the No. 3 best seller was a promotional deal Amazon ran on Kindle Unlimited — a departure from past years dominated by tech. With the deal, Prime members who hadn’t yet tried the service could sign up for three months of Kindle Unlimited, and get access to over 1 million books, for just $1. The service usually goes for $30 for the same time frame.

 

4. Instant Pot multi-cooker

Instant Pot DUO60, 6 Quart, $59.99 [Last year’s Prime Day price, $58.99]

Instant Pot Ultra, 8 Quart, $126 [Last year’s Prime Day price, $179.95]

The Instant Pot is not at all surprisingly in fourth place, especially seeing as the site sold a whopping 300,000 of them on Amazon Prime Day. 

Depending on the model you get, you can feed families of 6 or more in one fell swoop, and it can replace 10 common kitchen appliances with one: It’s a pressure cooker, slow cooker, rice cooker, yogurt maker, cake maker, egg cooker, sauté pan, steamer, warmer, and sterilizer. It also has 16 smart programs, which include Soup/Broth, Meat/Stew, Bean/Chili, Cake, Egg, and Slow Cook, among others.

Even without a sale, it’s a small kitchen appliance with big impact. It’s also the top of our list for the best instant cookers.

5. Dyson V8 Absolute vacuum

Dyson V8 Absolute Cord-Free Stick Vacuum (Refurbished), $369.99 [Last year’s Prime Day price, $364.99] 

Few people who invest in a Dyson vacuum ever regret doing so. The powerful suction drives deep into surfaces to remove dirt, dust, and debris, while the cord-free design makes it convenient to move around your space. It also filters the air as you clean, so your home will be cleaner from top to bottom. 

 

6. 23andMe DNA test

23andMe DNA Test, $199 [Last year’s Prime Day price, $99.99]

The 23andMe DNA test offers personalized genetic reports to help you learn about your ancestry, traits, and certain aspects of your health. All you do is take a sample of your saliva, send it to the company’s lab, and wait for results.

7. Tuft & Needle mattress

Tuft & Needle Queen Mattress, $595 [Last year’s Prime Day price, $459]

This discount was a good excuse to finally switch out the old, unsupportive mattress lurking in your room. It helps that Tuft & Needle’s mattresses, made with its signature pressure-relieving adaptive foam, are well received among shoppers already. They’re easy to set up, they have medium firmness and support, and they come with a 10-year limited warranty. 

8. Whynter portable air conditioner and heater

Whynter ARC-14SH Portable Air Conditioner and Heater, Dehumidifier, $499 [Last year’s Prime Day price, n/a]

Our pick for best portable air conditioner became a top seller perhaps because it was the dead of summer and shoppers couldn’t take the stifling heat in their homes any longer. This ultra-quiet unit is easy to maintain because it has an advanced self-evaporating technology. It’s also great because its use extends past summer, turning into a heater or dehumidifier. 

 

 

9. ECOVACS DEEBOT N79S robot vacuum cleaner

ECOVACS DEEBOT N79S Robot Vacuum Cleaner with Max Power Suction and Alexa Connectivity, $199.99 [Last year’s Prime Day price, $169.98]

The ECOVAC robot vacuum has a max-mode cleaning setting for when you need to clean with double the power, and it’s as easy as switching it on in the app or by remote. It works with Amazon Alexa and Google Home voice commands and has a 100-minute life battery, as well as auto-return charging. 

11. Fire TV Stick with Alexa Voice Remote

Fire TV Stick with Alexa Voice Remote, $39.99 [Last year’s Prime Day price on older generation model, $19.99]

With the Amazon Fire TV Stick, you can stream media to any TV with an HDMI input. Popular services like Netflix, Hulu, HBO Now, Showtime, Sling, and NBC are all available in addition to Amazon Prime Video. With Alexa capabilities, you can control the TV with your voice. The Stick is small enough to take with you when you travel, so you can plug it into a hotel TV, too.

The Fire TV Stick on sale last year was an older generation. The link above is for Amazon’s newest Fire TV Stick. 

11. Eufy Robovac 11 vacuum

Eufy Robovac 11 Vacuum, from $324.17 (currently only available from third-party sellers) [Last year’s Prime Day price, $159.99]

At just $160, Eufy’s vacuum was a great value buy. It’s only about three inches tall, allowing it to sneak under tables and couches to tackle the dirt of the most difficult-to-reach areas. The vacuum can run for 1.5 hours at a time, then recharges automatically. 

12. Bose QuietComfort 25 noise-cancelling headphones

Bose QuietComfort 25 Acoustic Noise-Cancelling Headphones, $177.50 [Last year’s Prime Day price, $125]

Any time Bose discounts its products this heavily, people tend to respond enthusiastically. This pair works particularly well for travelers thanks to its comfort and noise-canceling feature. It was sold at the lowest price we’ve ever seen over Amazon Prime Day. 

13. Sony wireless noise-canceling headphones

Sony Wireless Noise Canceling Headphones, $198 [Last year’s Prime Day price, $98]

Another tech brand not known for deep discounts, Sony was a predictable success given its name recognition and how great its products are. This pair’s noise cancellation adjusts to your environment with One Push and promises 35 hours of battery, as well as quick charging. There’s a built-in microphone for hands-free calls and use with your voice assistant.

14. Amazon Echo

Amazon Echo (2nd Generation), $69.99 [Last year’s Prime Day price, $69.99]

The Echo features Dolby speakers that play 360° audio with clear vocals and dynamic bass response, plus seven microphones so it can hear your commands even as music is playing. Available in three different fabric finishes and one wood finish, it doesn’t look too bad either, blending into living room or kitchen settings. 

 

15. Amazon Echo Dot

Amazon Echo Dot (2nd Generation), $39.99 [Last year’s Prime Day price, $29.99]

The Amazon Echo Dot is a miniaturized, unobtrusive iteration of Amazon’s popular smart home device. Play music, set alarms, send messages, look up information, control your Alexa-connected TV, turn lights on and off, and much more, all with your voice. 

If you’ve never tried one out before, we have a guide to help you make the most of its features. 

16. Amazon Echo Show

Amazon Echo Show, $229.99 [Last year’s Prime Day price on older generation model, $129.99] 

The newest Echo Show combines the speaker quality of the Echo and Echo Plus with the visual capabilities of the Echo Spot, and now has a larger (10″) HD screen and eight-mic array. Make a video call to a friend or family member, watch and follow recipe videos hands-free, and pull up the lyrics to sing along to your favorite song. 

The Echo Show on sale last year was an older generation. The link above is for Amazon’s newest Echo Show. 

17. Sennheiser HD 4.50 SE wireless noise-cancelling headphones

Sennheiser HD 4.50 SE Wireless Noise Cancelling Headphones, $199.95 [Last year’s Prime Day price, $99] 

A third over-ear, noise-cancelling option: Sennheiser’s vibrantly crisp headphones. Reviewers warn that it’s not the most comfortable for large heads, so proceed with caution. Other than that caveat, however, it’s a solid set for its price. It also has an impressive battery life of 19 hours, and up to 25 without the noise-cancelling feature. 

18. Kindle Paperwhite

Kindle Paperwhite E-reader, $149.99 [Last year’s Prime Day price on older generation model, $79.99] 

The most popular Kindle was $40 cheaper on Amazon Prime Day. It has a high-resolution display (300 ppl) and an adjustable built-in light. It’s lightweight, comfortable to hold, and lets you download millions of books with the click of a button instead of trying to shove a few more onto your bookshelf or in your backpack. 

The Kindle Paperwhite on sale last year was an older generation. The link above is for Amazon’s newest waterproof Kindle Paperwhite. 

19. Amazon Echo Spot

Amazon Echo Spot, $129.99 [Last year’s Prime Day price, $99.99] 

The small screen of the Echo Spot lets you video chat, watch videos, and see content at a glance. The compact size makes it perfect as a bedside smart alarm clock — one that gives you a glimpse of front-door cameras, thermostat and garage door controls, and more. 

20. Philips Sonicare Diamond Clean Classic electric toothbrush

Philips Sonicare Diamond Clean Classic, $169 [Last year’s Prime Day price, $119.95]

Philips Sonicare says its popular electric toothbrush removes up to seven times more plaque than a manual toothbrush. There are five brushing modes: Clean, White, Sensitive, Gum Care, and Deep Clean. 

21. Samsung Galaxy S8 unlocked 64GB

Samsung Galaxy S8 Unlocked 64GB, $371.56 [Last year’s Prime Day price, $499.99] 

Right now, the Galaxy S8 is at its lowest price, but at the time, shoppers were saving more than $200 on this smartphone. To enjoy its large screen and high-quality camera without committing to a mobile-provider contract, get this unlocked phone for less than $400 right now.

22. LifeStraw personal water filter

LifeStraw Personal Water Filter for Hiking, Camping, Travel, and Emergency Preparedness, $17.47 [Last year’s Prime Day price, $9.99]

The LifeStraw removes bacteria and parasites from water as well as microplastics, so you can have the peace of mind of a lightweight, mobile water purifier wherever you go. It’s a no-brainer for hiking, camping, travel, and being prepared for an emergency.

But even given its incredible utility, Amazon selling 150,000 still came as a surprise to most. 

23. Ring Video Doorbell Pro

Ring Video Doorbell Pro, $249 [Last year’s Prime Day price, $174.99] 

See exactly who’s standing at your door and finally catch your neighborhood package thief with this smart video doorbell. It monitors your home in 1080HD video with infrared night vision, then sends alerts to your phone or Echo device when motion is detected. 

24. Oral-B White Pro 1000 electric toothbrush

Oral-B White Pro 1000 Power Rechargeable Electric Toothbrush, $49.94 [Last year’s Prime Day price, $39.94]

An Oral-B electric toothbrush being sold for less than $40 kind of speaks for itself, especially since the genre is usually dominated by numbers that edge closer to $100. 

25. Breville BES870XL Barista Express espresso machine

Breville BES870XL Barista Express Espresso Machine, $479.95 [Last year’s Prime Day price, $469.99] 

Enjoy the riches of cafe-quality espresso at home with this Breville machine. It’s a bit of a splurge, as most espresso machines are, but it comes with everything you’ll need (save for the beans), and it’s pretty easy to use.

Amazon Cloud Cam Security Camera, Works with Alexa, $119.99 [Last year’s Prime Day price, $59.99]

In another deal that was too good to go unnoticed, Amazon discounted the Cloud Cam by 50%.
