Amazon Prime Day 2025 is fast approaching, and the sale is already underway on some items. To help you find the best early Prime Day deals, we've scoured Amazon for deals on the tech we love. As always, every deal we recommend here is on a product our reviewers have personally tested and approved--you won't find any shoddy dupes or mystery brands here. This year Prime Day runs for four days, July 8-11, rather than the usual two. That means there's twice as long to suffer save. Be sure to read our explainer on all the Amazon Prime perks you should be taking advantage of. Updated Thursday, July 3, 2025: We've add deals on Amazon's Kindle Essentials Bundle, Echo Spot, an Arlo security cam, two Tapo cams, the Jackery Explorer 300 power station, the Glimpse Sleep Mask, Brooklinen's organic sheets, and more. If you're looking to get a new Kindle and want a case, then snag this handy essentials kit while it's on sale for Prime Day. It includes the latest basic Kindle, a fabric cover, and a power adapter (which is also handy since Kindles only come with a charging cord, no adapter). The bundle only comes with a black Kindle, but you can choose from a couple of cover colors.

Few maintenance tasks are as tedious and time-consuming as cleaning your swimming pool. The good news is that robots can now perform that job, leaving you more leisure time to actually swim in your pool. We've spotted some great deals ahead of Amazon's Prime Day sale next week, and we'll add more as they become available. The recently reviewed Airrobo PC10 is a mid-range robotic pool cleaner that did a very good job on our test pool, and Amazon has knocked 42% off its list price, taking it down to 350. While we haven't had an opportunity to review the Wybot C1 robotic pool cleaner, we have obtained good results with some of the company's other products.

Achieving that perfectly manicured lawn is a whole lot less time-consuming now that a robot can do the job for you. And over the long term, a robot lawn mower will cost less than hiring a landscaper--and it won't expect a tip every week. Top-of-the-line models cost a pretty penny, but they can climb slopes and handle very large yards (we're talking acres of grass). While early robot lawn mowers required you to lay down a boundary wire to prevent them from wandering out of your yard, each of mowers listed here use advanced navigation technology that eliminates the need for any wires. The good news is that we've already spotted some great deals on robot lawn mowers ahead of Amazon's Prime Day sale, and we expect there will be more when the sale actually gets underway on July 8.

Prime Day is nearly as good of a time to buy a robot vacuum on sale as Black Friday. It's the first big sale event of the year for many 2025 robot vacuums that just came out in the spring after being announced at CES -- most of them were far too fresh to go on sale for Amazon's Big Spring Sale in March. Plus, I think I can already tell that Prime Day is going to beat those spring robot vacuum deals. Most of said deals are already back in the weeks ahead of Prime Day, and it's safe to assume that new record low prices will be hit as we approach the actual week of Prime Day (July 8 through 11 this year). I also expect way better Roomba deals this Prime Day than we saw in the spring, now that the new Roombas released in March have had a few months on the market.

If you've been wanting a pair of Ray-Ban Meta smartglasses, this is the best price I've seen since last year's Black Friday. Amazon has pairs as low as 239 right now, both with and without tinted lenses. They offer the classic Wayfarer style, so they look good on just about everyone. The sale is limited to what's in stock right now, so grab the color and the size you want before they sell out. When talking about the Ray-Ban Meta glasses, most people focus on the built-in camera.

We propose Sketched Online Newton (SON), an online second order learning algorithm that enjoys substantially improved regret guarantees for ill-conditioned data. SON is an enhanced version of the Online Newton Step, which, via sketching techniques enjoys a running time linear in the dimension and sketch size. We further develop sparse forms of the sketching methods (such as Oja's rule), making the computation linear in the sparsity of features. Together, the algorithm eliminates all computational obstacles in previous second order online learning approaches.

Online shopping is a complex multi-task, few-shot learning problem with a wide and evolving range of entities, relations, and tasks. However, existing models and benchmarks are commonly tailored to specific tasks, falling short of capturing the full complexity of online shopping. Large Language Models (LLMs), with their multi-task and few-shot learning abilities, have the potential to profoundly transform online shopping by alleviating task-specific engineering efforts and by providing users with interactive conversations.
