It's always a good idea to look for discounts on big-ticket items on Prime Day, and robot vacuums are no exception. These machines can be some of the most expensive gadgets you buy for your home, with high-end models costing close to (or more than) $1,000 normally. Thankfully, Prime Day is a good time to pick up a robo-vac for much less than that since premium models tend to be hundreds of dollars off, and even those that already have budget-friendly prices are also often discounted. Here are the best robot vacuum Prime Day deals we could find on all of our favorite machines.

iRobot Roomba 694

The iRobot Roomba 694 has dropped to $199 for Prime Day. It's normally our favorite budget robot vacuum, so this discount makes it an even better buy. We like its minimalist yet attractive design, strong suction power and easy-to-use companion app.

iRobot Roomba s9+

The premium Roomba s9+ is on sale for $600 for Prime Day. This is the most expensive robot vacuum that iRobot makes, and it's currently one of our favorite high-end models. It might be overkill for most people, but it's a robo-vac that does an excellent job of cleaning both hard and carpeted floors, and doesn't choke up at the first sign of pet hair. We also like that it comes with a clean base into which it will empty its dustbin after every job.

iRobot Roomba j7+

The iRobot Roomba j7+ has been discounted to $649 for Prime Day. This is one of the company's newest robot vacuums and we like that it has strong suction power and comes with a clean base. The j7+'s claim to fame, though, is its advanced obstacle avoidance, which helps it steer clear of furniture and other objects while it's cleaning. This includes a robo-vac's arch nemesis — pet poop.

Shark AI Ultra 2-in-1 robot vacuum

Shark's vacuum-and-mop machine has dropped to $380 for Prime Day. It's one of the best robot vacuums you can get right now because of its versatility and decent starting price, so if you can pick it up while it's on sale, that's even better. It comes with a water reservoir with a cloth attached to it that lets you mop hard floors when you need to. The standard dustbin will hold all debris during vacuuming, and the machine is smart enough to empty its clean base automatically after every vacuuming job (you'll have to empty the water reservoir on your own).

Shark AI Ultra robot vacuum

A top pick in our robot vacuum guide, Shark's AI Ultra robo-vac is on sale for $419 for Prime Day. It's just as easy to use and effective as a similar Roomba, but you can often find it at a notably cheaper price point. We found that it cleaned carpet and hard floors well, and its included clean base is bagless, which means you won't have to spend more money over time buying proprietary garbage bags for it.

Anker Eufy RoboVac X8 Hybrid

Another vac-and-mop combo, the Eufy RoboVac X8 Hybrid has dropped to $300 for Prime Day. Like a lot of other Anker/Eufy devices, the RoboVac X8 Hybrid already starts out much cheaper than its competition but it works nearly just as well. It can vacuum and mop, thanks to its included water reservoir, and we were impressed by its easy set-up process, four cleaning modes, smart home mapping and handy "tap-and go" feature.

Shark makes some of the best robot vacuums around and you can currently save quite a bit on a self-emptying model. The device is 50 percent off as it has dropped to $300 at Amazon. That's the lowest price we've seen for it to date.

Robot vacuums are an excellent quality of life upgrade for many people compared with having to clean floors manually with a standard vacuum. Shark's RV1001AE model has several features that make it a strong option. It has a bagless, self-emptying base that Shark says can hold up to 45 days worth of muck. You won't need to buy disposal bags like you would with other models.

The vacuum is able to map out your home. You can schedule cleanings for your entire home or ask the robot to take care of a certain room or area immediately using the SharkClean app, Alexa or Google Assistant.

Shark says the vacuum has powerful suction as well as a self-cleaning brushroll that can pull debris and hair from carpets and hardwood floors. The Shark IQ Robot uses a row-by-row cleaning method. When it's done, it returns to its dock to recharge.

The spotted lanternfly may look innocent, but these ravenous creatures have been known to decimate crops, causing more than $500 million in damages to various fruit trees since being accidentally introduced to this country nearly a decade ago. The big idea right now is to introduce several species of wasps into the mid-atlantic ecosystem to hunt and eat the lanternflies, but students at Carnegie Mellon University's Robotics Institute have developed an alternative plan in the form of a robot death machine.

It’s called TartanPest and uses a combination of technologies and components to autonomously hunt down and destroy lanternfly egg masses. It starts with an electric tractor for movement and a suite of cameras for traversal. This computer vision is also constantly on the hunt for egg masses, containing up to 50 lanternfly eggs. Once it finds a mass on a tree, rock or even a rust metal surface, a robot arm with a spinning brush attachment goes in for the kill, scrubbing the eggs away like so much trash.

"Currently, spotted lanternflies are concentrated in the eastern portion of the nation, but they are predicted to spread to the whole country," said Carolyn Alex, an undergraduate researcher on the TartanPest team. "By investing in this issue now, we will be saving higher costs in the future."

There’s some deep-learning algorithms at work here to locate the egg masses, trained using a large image data set. The robot does work autonomously but requires a human on-hand to fix any issues as they arise. So it’s probably not the most efficient way to eradicate spotted lanternflies. Still, it’s pretty darned cool and everybody loves a good killer robot.

This is just a prototype design for now, as the team designed the construct as part of Farm-ng's 2023 Farm Robotics Challenge. In other words, if lanternflies are getting you down, you have a while to wait before you can unleash an army of killer robots. In the meantime, you can always try an army of killer wasps instead.

Avoiding manual floor maintenance is a lovely thing, but a good robot vacuum will cost you. Our current favorite pick for a mop and vac combo, iRobot's Roomba j7+ usually sells for $1,099 but Wellbots will knock $300 off the list price when you use the code 300ENGADGET at checkout. That beats a $200 discount we saw earlier this year and represents an all-time low for a gadget that "earned its place" in on of our senior editors' smart home. Wellbots has a few other vacs on sale too, also with discount codes, listed below. 

Unlike some combo machines, in which you have to program where to mop and where to use the vacuum, the Roomba Combo j7+ senses when it's rolling over hard floors and drops down the on-board mop pad accordingly. It comes with a clean base, which sucks out the dry debris after a run, but you'll have to take care of adding and emptying the mop water yourself. iRobot machines continually top our lists, in part thanks to the accurate room mapping, easy-to-use app and excellent obstacle avoidance — qualities it shares with the vac-only sibling. 

Wellbots is currently discounting the Roomba j7+ by $220 when you use the code 220ENGADGET. That brings the unit down to $579, which also beats a previous discount from the same seller earlier this year, and is the lowest price we've seen outside of Black Friday promotions last November. The standard (non-combo) Roomba j7 is the runner up mid-range vac in our guide and this version simply includes a clean base to suck out the dirt after it runs. One thing we should note is that process is loud but it gets you a bit closer to fully autonomous cleaning. 

If you're fine with emptying the collected debris yourself, you can save a little on the base model Roomba j7. Wellbots is also offering $220 off that model, using the same code. That brings it down to just $379, which doesn't quite beat the deal Wellbots offered late last year, but is still a tidy discount.

And finally, if premium is what you want, you can get just that with iRobot's Roomba s9+. The same code also takes $220 off the $999 list price, making it $779 instead. It's the premium pick in our robot vacuum guide and comes complete with copper accents. Of course, doesn't just look pretty, our resident robot expert, senior commerce editor Valentina Palladino, calls it, "nothing if not one of the best robot vacuums out there."

With an instantly recognizable hook and effervescent melody, Vanessa Carlton’s debut single A Thousand Miles hit the 2002 Billboard Charts like a neutron bomb, earning nominations for the Grammy Award for Song of the Year and the Billboard Music Award for Top 40 Track of the Year. Featured prominently in 2004’s White Chicks, Terry Crews credits the undeniable smash with helping launch his acting career. 

The accompanying music video saw Carlton and her piano rolling through Newbury Park, California, and portions of downtown Los Angeles. Twenty-one years later, a team of hobbyist roboticists have brought Carlton’s music back to the public ear — this time, to the streets of San Francisco with an animatronic performer and remotely deployable disco ball.

The robot, which currently doesn’t have much of a moniker from the team beyond “The Robot,” is the brainchild of San Francisco-based aerospace engineer Ben Howard, electrical engineer Noah Klugman, lawyer Lane Powell (with additional assistance from local puppeteer, Adam Kreutinger). “This is just a thing that we've done together, the three of us, to try to create some joy,” Klugman told Engadget during a recent video call.

The trio first collaborated during the pandemic. “Kids couldn't really trick or treat properly,” Howard explained. “So we put together a kind of spooky Halloween candy dispensing robot that could drive around the streets and any kids who were brave enough could walk up, have a conversation with it and get some candy.” That project inspired them to look into developing a robot with year-round appeal. A “piano playing Muppet seemed like a good thing to do,” he continued, and from that the Thousand-Mile Machine was born.

The team started with an outdated food delivery drone model, obtained from “a friend of a friend,” as the mobile platform on which to build out the rest of the construct. “When companies get rid of these things, if they're cool pieces of hardware, there are plenty of engineers around the city who like to modify them and turn them into fun projects,” Howard explained. “There's a big community of people who are sharing cool hardware around.”

“I came to acquire [the wheeled base] and we wanted to do this music playing robot.” he added. “Then, when you think about piano player that roams around the city, immediately that [Vanessa Carlton] video comes to mind. It's so iconic.”

The nearly 400-pound robot measures roughly five feet long on a side and about four feet tall, narrow enough to fit on a sidewalk and into the TEU container workshop in which it was built at San Francisco’s Box Shop. The wheeled base is controlled remotely and manually, while the puppet’s performance — from the hand and head movements to the big disco ball reveal — are all part of a prerecorded act, akin to Chuck E Cheese’s animatronic Pizza Players band. A single button press is all that’s needed to start the performance.

Vanessa Carlton herself reportedly met the robot during a recent event in Petaluma, “it seemed like she enjoyed it,” Klugman noted. “Everyone we've met in San Francisco has seemed to really love it. I think the response has been overwhelmingly positive.”

“That was very much [the case with] everyone we encountered when we were out filming,” Lane added. “Just really happy to watch it and excited to talk to us about it and just 100 percent positive from all ages and all walks of life all over the city. It was a really cool experience.”

If you've held out on buying a quality robot vacuum to avoid a splurge, you might find yourself finally hitting the "buy now" button. The Shark AV1010AE Robot Vacuum with a XL Self-Empty Base is 50 percent off for today only, down to $300 from $600. The half off robovac is a good mid-tier choice, with features like home mapping, voice command through Google Assistant or Alexa and multi-surface brush rolls for better floor and carpet cleaning.

The vacuum connects to WiFi, meaning that you can create cleaning schedules and power it on and off through an app. It will automatically return to its port to reacharge if its running low on battery. The robovac's base also holds up to 45 days of dirt, collecting it each time it comes back to the port — and providing ample time before you need to interact with the vacuum.

The Shark AV1010AE Robot Vacuum's gray model is also on sale for $300. It's a 40 percent discount, down from $500, since only available with a 30-day self-emptying base. The AV1010AE with a self-cleaning brush roll is still full price, at $549.

Shark products are reliable options overall, and the AV1010AE model has many of the same benefits as the Shark AI Robot Vacuum with Base that we chose as 2023's best midrange vacuum. The AI model holds up to 60 days of debris and uses a laser scanner to map out the house. These add-ons are more accessible than usual, as the Shark AI is 25 percent off right now, down to $450. If they don't matter to you, the Shark AV1010AE robot vacuum will be half-off until the deal turns back into a pumpkin before morning.

There's one less competitor in the robot vacuum world. Neato Robotics is shutting down as the company hasn't reached its "self-defined economic goals" for years, parent company Vorwerk Group tellsTechHive. The firm's sales haven't met expectations, in other words. Vorwerk is promising cloud and repair support to Neato customers for "at least" five years, so your robovac should continue to run for a while longer.

The move will affect 98 jobs, Vorwerk says. Users started worrying weeks ago, when users noticed a broken customer sign-in page. Neato's Facebook and Twitter accounts vanished, and support staff fell silent. Vorwerk is fixing the login issues and says they're not connected to the shutdown.

Neato emerged in 2005 and soon became one of the main competitors to iRobot's Roomba series. It stood out by pushing the limits of robot vacuum technology, such as by adding WiFi in 2011 and LiDAR mapping in 2020. Vorwerk bought Neato in 2017, but continued to run the brand independently. Neato ran into trouble, and restructuring efforts didn't turn the company around.

The closure isn't surprising. iRobot has long dominated robovacs, and claimed 46 percent of the market in 2020 according to Statista. Neato, by comparison, had roughly 3 percent in preceding years and was already fading away by 2020. Competitors like Anker's Eufy brand, Roborock and Shark have entered the field and sometimes undercut Neato on price.

A shutdown may not be good news for iRobot, though. American politicians are already concerned about the potential harm of Amazon's proposed iRobot acquisition to the competitive landscape, and European regulators are reportedly close behind. Neato's demise further reduces that competition, even if it hasn't been a heavyweight for a while.

The iRobot Roomba S9+ premium robot vacuum is currently on sale for $250 off at Wellbots. Typically costing $999, ordering with the coupon code 200ENGDT will bring its price down to $749 — still very expensive, but a good value for this advanced cleaning machine. And if that’s more than you want to pay for a vacuum cleaner, you can save on cheaper models too.

The S9 series of Roomba vacuums build on the best qualities of the Roomba i7 line while adding some enticing extras. First, they offer 40 times the suction power of other robot vacuums while trapping mold and pollen allergens. It also has a different shape: Instead of being completely circular, it has two squared edges, which help it to clean more thoroughly around corners.

If you’re eyeing models from the j7 series, you can take $200 off several other iRobot vacuums with the same coupon code (200ENGDT), including the Roomba j7, Roomba j7+ and Roomba j7+ Robot Vacuum & Mop. The j7 series uses AI-driven navigation for enhanced obstacle avoidance — including pet poop. Of course, it also has powerful suction, precise mapping and an easy-to-use app. The j7 is one of Engadget’s top midrange picks for the best robot vacuums.

The standard model gets you the vacuum itself, the j7+ adds a self-emptying cleaning station and the j7+ with vacuum and mop includes the station and wet-mopping capabilities. The 200ENGDT coupon cuts the j7 (usually $599) down to $399 and the j7+ ($799 MSRP) to $599. and the j7+ with mop ($1,099 MSP) is only $899. Finally, you get free shipping on your order.

Starting today, Uber Eats customers in Fairfax, Virginia can get their next meal delivered by a robot. In an expansion of the company’s existing partnership with Cartken, Uber has begun offering automated deliveries in the city’s Mosaic District. With today’s announcement, a select number of the more than 40 restaurants in the area have begun transporting their food aboard Cartken’s six-wheeled robots. Among the restaurants participating in the pilot include Our Mom Eugenia, Pupatella and RASA.

Uber has been testing autonomous delivery robots in a handful of markets throughout the US. Last May, the company launched two pilots in Los Angeles with the help of Motional and Serve Robotics. More recently, Uber signed a 10-year deal with Nuro to use the company’s vans for autonomous deliveries in California and Texas. Cartken, it should be noted, also works with Grubhub to deliver food on college campuses. The firm’s robot uses NVIDIA’s Jetson tech, alongside cameras and sensors, to navigate streets and sidewalks. They can travel at up to six miles per hour and carry about two full paper grocery bags of cargo to their destination.

If you've been putting off any spring cleaning — who hasn't? — now might be the time to consider a helper. Robot vacuums have been popping up everywhere and, though they can be pricier than a do-it-yourself option, the Shark AI Ultra 2-in-1 robot vacuum is currently making a play for your home with a 43 percent off sale. It's still not an impulse buy in the check out lane, but, at $400 versus $700, it's the best deal we've seen since it launched.

This 2-in-1 model uses smart home mapping to clean in a precise grid, empties itself and has improved suction power. Shark also claims the mops can scrub floors 100 times per minute. Plus, like most robot vacuums, it's controlled through an app.

Shark has produced a few different robovacs in recent years, alongside impressive competitors like iRobot and Anker. This sale makes the 2-in-1 model cheaper than Shark's standard AI Ultra vacuum — even with its price currently down from $600 to $485. The standard model doesn't differ too much from the 2-in-1 model and made the list of our best robot vacuums of the year. But, it is missing a few features, such as the water reservoir, reusable mopping pads and improved suction. 

If you don't care too much about your robovac self-emptying, the Shark RV2410WD IQ 2-in-1 Robot Vacuum and Mop is a cheaper option, on sale at $295 versus $380.
