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 Amazon Spring Sale has arrived, bringing a slew of discounts on household essentials, fashion, outdoor gear and even furniture. We at Engadget are focused on tech, and while the selection this time around isn't quite as good as that of Amazon Prime Day in July, there are some decent discounts to be had. Some of our favorite robot vacuums, air purifiers, headphones and storage gear are on sale right now for some of the best prices we've seen this year so far. Below, you'll find all of the best tech deals we could find in the Amazon Spring Sale. The shopping event runs through March 31, so be sure to check back for the latest deals as they become available.

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.

Dyson's one of the biggest players in the cordless vacuum and air purifier space (and, more recently, hair styling as well), but it's kept a relatively low profile in the robot vacuum market. After being available in other regions, the Dyson 360 Vis Nav is now available to order in the US for a whopping 1,199 from Dyson direct and other retailers like Amazon. While we haven't had the chance to test the 360 Vis Nav yet, we were able to get more details from Dyson about how the new robot vacuum works. A few things stand out as departures from traditional robot vacuums, the first being the 360-degree vision system that uses a camera on the top-center of the robot to map out your home as it cleans. Home mapping isn't new in this space, but Dyson claims that the images captured by this vision system will help the machine better understand the layout of your home, including where obstacles like furniture live, make note of corners and edges and help it recognize where it's cleaned and where it still needs to go to finish a job.
