It seems like only a few years ago that Anker made nothing more than batteries and chargers . But 15 years into its history, the company's CES portfolio continues to illustrate how much it's expanded. Among other announcements, the company has a new robot vacuum, video doorbell, outdoor light and smart lock. The company hopes its Eufy Clean Robot Vacuum Omni S2 will be your next robovac. Anker claims the vac works on shag carpets up to about 2 inches (5 cm) in pile height.

Amazon's Big Spring Sale has finally reached its last day. Like last year, the deals are focused less on tech and gadgets and more on home, cleaning and fashion discounts. That's not Engadget's area of expertise -- except when it comes to robot vacuums, where home cleaning and hi-tech neatly intersect. We've tested dozens of these handy automatic floor cleaners and put the results in two buying guides one for budget models and one covering the best of the best. We've also tried out a few cordless vacs, which make good spot-cleaners to supplement automated cleaning. Right now, a number of our picks and related models are on sale and we've rounded up the best deals on vacuums Amazon's latest sale has to offer.

One notable trend at CES earlier this year was the quirky robot vacuum. It seemed every third booth had a new model that could climb stairs, pick up socks, serve drinks and, oh yeah, suck up dirt from your floor. Now that Amazon's Spring Sale is here, we're seeing lots of discounts -- not on those wacky prototypes, but on robo vacs that make keeping your floors clean easier and automated. Engadget has two guides to these handy home gadgets, based on years of testing and reviewing products from brands like iRobot, Shark, Dyson, Eufy and more. Here are the best deals on robot vacuums and cordless stick vacs we could find for the Big Spring Sale. This "essential" Roomba is relatively no-frills, but it has the added benefit of being a mopping robot in addition to a vacuum.

We've now hit the third day in Amazon's Big Spring Sale and, like last year, it seems to focus less on tech deals and more on home, cleaning and fashion discounts. We've tested dozens of these handy automatic floor cleaners and put the results in a couple of our buying guides. Most of the deals that debuted when the sale kicked off are still live. Well, really, many of these deals went live before the sale's official start date this Tuesday. But they may not stick around long after the sale is done on Monday, March 31. As it stands now, a number of our recommended robot and cordless vacuums are on sale and we've rounded up the best deals we could find, right here.

The company behind Roomba robovacs told investors earlier this week that revenue was substantially down and it's struggling to pay its debts. Amazon was briefly tapped to acquire the robot company iRobot, but the threat of a European Commission investigation led to the retailer terminating the deal -- apparently happy enough to pay off the 94 million termination fee. That, however, isn't enough to tackle the 200 million loan iRobot took out to survive long enough for Amazon to come to the rescue. It's extra rough when the company announced, just the week before, a bunch of new models, including a new Roomba that can compact debris and dust, so it only needs to be emptied every few weeks. At the same time, rival robot vacuum cleaners are getting more versatile, more complicated and more intriguing.

The Roomba 205 DustCompactor Combo Robot is being advertised as "the industry's first onboard mechanical debris-compacting system." In other words, it squeezes dust and debris together like, well, a garbage compactor. This allows users to go eight weeks without having to empty the vacuum. It also eliminates the need for a dedicated debris bin. Otherwise, the 205 is a full-featured hybrid vacuum/mop.

Spring cleaning (it'll be here before we know it!) The robovac typically costs a whopping 900, but you can use our exclusive code ENGAD415 at checkout to cut its price to 485, a record low. The Roomba j9 has a three-stage cleaning system, multi-surface rubber brushes and suction that iRobot says is 100 percent stronger than its Combo i Series robovacs. Although this model doesn't mop like its more expensive sibling, the Combo j9, it will suck up dirt and debris on your carpets and hard floors. Save 415 on the premium robovac.

Convenience has always been the big promise of robot vacuums. Don't clean your house yourself -- instead, push a button and have a little robot putter around your home, sucking up all the dirt and debris in its path. Indeed, they are convenient, but they haven't fully replaced a manually operated cordless vacuum. Chances are, you have either a robot vacuum or a cordless vacuum in your house right now. Anker's home brand Eufy wants us to live in a world where you can have both without spending money on two separate devices that need two separate spots in your home. Announced at CES 2025, Anker's Eufy E20 is a first-of-its-kind robot vacuum that turns into a cordless stick vacuum and comes with all the necessary attachments to do so, plus a self-emptying base.

CES is known for putting the spotlight on wacky innovations and Eufy came prepared for this year's event. The company just revealed its E20 robot vacuum, which can actually transform from a traditional robovac to a manually-controlled stick vac. This is the first time we've seen something like this. Some robovacs include additional stick vacuums, but do not transform into them. On the outside, it looks similar to competing robot vacuums from companies like Roomba.
