Hoover HF4 Hydro for £199: For UK folks in flats or small houses with a mix of carpet and hard floor, this cordless, space-saving vacuum and mop from Hoover could be a smart pick. You get a standard cordless stick vac with around half an hour of battery life, but you can switch the head to mop. It’s excellent for cleaning hard floors, with a shape that gets right into corners and two rotating pads to lift stains. But the water tank, contained within the head, is tiny, the vacuum is only moderately powerful at lifting, and battery life drops to just 15 minutes in turbo mode.
Hoover SmartWash Automatic Carpet Cleaner for $250: It’s bulky, but it has automatic cleaning and drying cycles—pushing it forward releases the solution and pulling it back starts the drying process. After you’ve gone over the whole area, you can turn just the drying mode on for an extra pass if the carpet needs it. The handle comes out with the click of a button, and you can use its separate tank with a cleaning solution to spot-treat before vacuuming. A hose and separate antimicrobial pet tool can clean stairs or any other hard-to-reach areas that need extra elbow grease. Some customer reviews say it worked well for a few months but then shorted out. We’ll keep trying it to see if we run into that issue. —Medea Giordano
Bissell Little Green Portable Carpet Cleaner for $79: If you’ve landed on the cleaning side of TikTok, you’ve probably seen people cleaning their carpets and furniture with this Little Green machine. This opens up the world of upholstery cleaning too, not just carpets. It worked well and it’s easier to store and tote around your house than our top pick. But use the included hose-cleaning tool frequently. These hoses can get nasty. —Brenda Stolyar
Cleaners We Like for Hard Floors

Dreame H14 Pro for $380: The Dreame H14 Pro is quite large, but I found it easy to maneuver, and it can lie flat to get under furniture. A handy LED headlight helps you see what you are cleaning clearly. A full charge proved enough to do all my hard floors twice over, and the result was super shiny. What I love about this vac is that it effectively cleans up dry or wet spills, so whether you are cleaning cat litter or a spilled bowl of cereal, it performs. It’s best for cleaning recent spills but can shift stubborn stains with repeated passes on Ultra mode. When you finish, you can return it to the charging cradle and trigger the self-cleaning mode to sterilize the soft roller and dry it (though it gets loud and takes a long time). No one wants to install an app or create an account just to use a vacuum, but it enables you to choose modes and schedule the self-cleaning, which could be handy if you want it to wait until you go out. —Simon Hill
Shark S5003D Genius Steam Mop for $100: This steam mop is great for cleaning hardwood, tiles, or laminate flooring (not carpets). Simply fill the water tank, plug it in, and attach one of the mop pads. It has three heat levels, and you press down to release a jet of steam for stubborn stains. There’s no need for any detergent, it’s light and maneuverable, and it doesn’t require much space. The clever pad design enables you to flip it over when one side is soiled, and the mechanism makes it easy to attach, with a button to detach the dirty pad, which is machine washable. (You get two pads in the box.) I regularly use this mop to clean laminate, composite, and tile floors, but you must be careful using steam, especially on wood or vinyl flooring. Test it on the lowest heat setting before going over the whole floor. There are no special attachments or extras here, and it’s only suitable for use on hard floors. You also need to empty any remaining water if you don’t plan on using it for a while, or the tank can go nasty. —Simon Hill
Karcher SC 3 for $164: If your budget can stretch, this option is better if you want attachments and the option to steam-clean harder-to-reach surfaces and your hard floors. It’s good for complete kitchen or bathroom cleaning without the need for any detergent or other products. It’s effective for cleaning glass and mirrors too. It only comes with one microfiber cover, and it’s not recommended for use on fabrics or carpets. —Simon Hill
Not Recommended
Eufy E28 HydroJet Robot Vacuum with Carpet Cleaner for $1,400: I generally love Eufy’s attractive, smart, multipurpose robot vacuums, and since I have two dogs and two kids, I was expecting to love a robot vacuum that could also mop hardwood floors and has a detachable carpet cleaner. Unfortunately, the water injection system is wonky. It has to be perfectly positioned to get water from the portable carpet cleaner tank (I often had to tap it into place), and every time I mopped, it leaked constantly all over my kitchen floor. At least the carpet cleaner was effective. —Adrienne So
Things to Consider When Shopping for a Carpet Cleaner
There is a lot to think about when shopping for or using a carpet cleaner, such as how much space you’ll need for storage and whether you should rent or buy. Here are some tips to keep in mind.
Carpet cleaners are heavy and bulky, especially when filled with water. They can be harder to maneuver than regular upright vacuums. They will also need quite a bit of storage space.
Tackle stain-causing spills immediately. Most households only need to wash carpets once every six months to a year, but spot cleaners are ideal for treating immediate spills, plus they’re easier to store and use.
You likely won’t use a carpet cleaner often, so it’s OK to consider hiring professionals to do your whole home, especially if you have limited storage space. (It also can depend on how dirty and stained your carpets are.) Look at options for renting a machine from local businesses or retail stores like Home Depot. You’ll be able to get the benefits of a commercial-grade cleaner without paying a fortune.
Clean your carpet before you use a carpet cleaner. This may seem counterintuitive, but you don’t want dirt and hair to form wet clumps that block the cleaner. And if you haven’t washed your carpets in a while (or ever), be prepared for an embarrassing amount of hairy clogs to fill the dirty water tank.
The carpet shampoo or detergent you use is important. Manufacturers often insist you use their brand, and while other types may work fine, you might void your warranty (although I have no idea how they’d know). Most carpet cleaners come with some detergent.
Try, try, and try again. It can be disappointing to fire up a carpet cleaner and find that it’s incapable of removing that old red wine stain or ground-in toothpaste. Don’t lose heart. Multiple cleaning sessions can sometimes chip away at established stains, and at least reduce, if not remove, them.
Drying your carpets can take a long time. Most carpet cleaners have different settings, and they will suck up some of the water, but they all leave carpets a bit damp. The deeper cleans tend to leave carpets wet, so think about how you might speed drying time. Use fans, fire up the heating, or do your carpet cleaning in the spring and summer months when you can leave windows open.
Protect your hearing. Of all the ways you can damage your hearing, a carpet cleaner is perhaps the least fun, so protect your ears. Some of these get very loud, so wear earplugs while you work.

Here’s Every Country Directly Impacted by the War on Iran
On February 28, United States and Israeli forces launched a series of strikes on Iran, kicking off turmoil in the Middle East.
Pete Hegseth, the secretary of the Department of Defense, said in a recent press conference that the operation could last as long as eight weeks. President Donald Trump himself said in a press conference on March 2 that the administration projected the operation would last four or five weeks but had “the capability to go far longer than that.”
This week Iran has responded in turn, attacking Israel, regional US embassies and military bases, and other sites across the Middle East. Iran has peppered neighboring countries with hundreds of drone and ballistic missile strikes since the operation began. While many of these have been intercepted, over a thousand people have died in the region and multiple buildings have been damaged, including luxury hotels in Dubai, US military bases and embassies, and international airports and marine ports.
Israel has also started bombarding Lebanon, following strikes at the country by the Lebanese militant group Hezbollah.
The Trump administration has given various, and at times seemingly contradictory, justifications for the military action, citing everything from potential “nuclear threat” to unverified claims that Iran attempted to interfere in the 2020 and 2024 US presidential elections. As of March 5, Congress, which in the US has the sole power to declare war, has not done so.
The attacks have already disrupted supply chains, creating uncertainty for the oil and gas and fertilizer industries as key infrastructure has been targeted or shut down out of caution. Shipping traffic has halted along the Strait of Hormuz, a critical route.
As the conflict continues to escalate and expand, WIRED is tracking which countries have been affected and how. This article was last updated on March 5.
Iran
As of March 4, Iranian state media estimates that over 1,000 people have died in the country since the US-Israeli attacks began. Several schools and hospitals have been hit, according to Al Jazeera. The Israeli Air Force says it has struck Iran with over 5,000 munitions since the beginning of the operation.
Israel
Israel has faced retaliatory strikes from Iran. As of March 4, at least 11 people have died and over 40 buildings have been damaged in Tel Aviv, according to Al Jazeera.
Azerbaijan
On March 5, Azerbaijan said drone attacks launched from Iran had crossed over the country’s borders and damaged an airport building and two civilians. President Ilham Aliyev of Azerbaijan said that the country’s military forces “have been instructed to prepare and implement appropriate retaliatory measures,” according to Reuters. Iran has denied responsibility for the attacks, according to Al Jazeera.
Bahrain
Missile and drone strikes have targeted different locations in Bahrain, including a US naval base, according to the BBC. On March 2, Amazon reported that a drone strike occurred in close proximity to one of its data centers in the country. CNBC later reported that Iranian state media said that Iran had targeted the data center because of the company’s support of the US military.
Cyprus
On March 2, a drone strike hit a British air base in Cyprus, according to Reuters. It caused limited damage and no casualties. Greece, the UK, and France have lent defensive support to the country, according to a Bloomberg report.
Iraq
Since February 28, there have been reports of multiple Iranian strikes aimed at a US military base near the Erbil International Airport, according to the nonprofit monitoring group Armed Conflict Location and Event Data.
Jordan
Jordan’s armed forces have intercepted dozens of missiles since the start of the conflict. At least one Iranian-backed militant group in Iraq has claimed responsibility, according to the Associated Press. On March 2, the US Embassy in the country announced that all its personnel had temporarily departed.
Kuwait
Kuwait has endured multiple waves of Iranian missile and drone attacks since February 28. On March 2, US Central Command said in a statement that three US fighter jets were accidentally struck down by Kuwaiti air defenses during an attack that included Iranian aircraft, missiles, and drones.
Lebanon
Israel attacked southern Lebanon after the militant Lebanese group Hezbollah launched rocket and drone attacks against them. Lebanon prime minister Nawaf Salam subsequently banned Hezbollah’s military and security activities, according to Al Jazeera.
Oman
Oman’s Duqm commercial port has been hit by several drone attacks, according to Al Jazeera. Omani authorities have said at least one oil tanker off the country’s port of Khasab in the Strait of Hormuz has been attacked.
Qatar
On March 2, QatarEnergy posted on X saying that it would halt production of liquified natural gas following a military attack on its operational facilities in the country. It did not attribute the attack to any particular country. On March 3, it posted again, saying that it would also stop the production of additional products, including urea, polymers, methanol, and aluminum.
Saudi Arabia
Infrastructure in Saudi Arabia has been targeted with projectiles. On March 3, the US embassy in Riyadh, the country’s capital, was damaged following an attack. On March 4, Reuters reported that one of the Saudi Aramco’s largest domestic refineries of Saudi Aramco, the majority state-owned oil company, was targeted by an attempted drone attack.
Syria
Tom Fletcher, the United Nations undersecretary-general for humanitarian affairs and emergency relief, says that civilians and civilian infrastructure were under attack in several countries including Syria.
Turkey
On March 4, the Turkish Ministry of National Defence announced that NATO had intercepted ballistic munitions launched from Iran, and that munition fragments had fallen into Hatay, a province that borders the Mediterranean Sea and Syria. Iran has denied any missile launch towards the country.
United Arab Emirates
As of March 4, UAE Ministry of Defence officials say that the country has intercepted hundreds of drone and missile attacks from Iran. Despite the relatively high rate of interceptions, debris created by the fallout has still damaged areas of the country. In Dubai, the luxury hotel Burj Al Arab was struck by debris, as well as the Palm Jumeirah, a man-made island home to high-end hotels and apartments. On March 2, Amazon Web Services announced that two of its facilities were directly struck in the country, causing “elevated error rates and degraded availability.”
Countries Evacuating Citizens
On March 2, US assistant secretary of state for consular affairs Mora Namdar posted on X urging Americans to depart from several middle eastern countries due to “serious safety risks.” On March 4, Reuters reported that the US military has offered seats on military transport planes to Americans trying to leave the region.
Over a dozen countries have announced that they will be evacuating their citizens from the area or sponsoring repatriation flights, including the UK, Ireland, Germany and Italy.

OpenAI Had Banned Military Use. The Pentagon Tested Its Models Through Microsoft Anyway
OpenAI CEO Sam Altman is still in the hot seat this week after his company signed a deal with the US military. OpenAI employees have criticized the move, which came after Anthropic’s roughly $200 million contract with the Pentagon imploded, and asked Altman to release more information about the agreement. Altman admitted it looked “sloppy” in a social media post.
While this incident has become a major news story, it may just be the latest and most public example of OpenAI creating vague policies around how the US military can access its AI.
In 2023, OpenAI’s usage policy explicitly banned the military from accessing its AI models. But some OpenAI employees discovered the Pentagon had already started experimenting with Azure OpenAI, a version of OpenAI’s models offered by Microsoft, two sources familiar with the matter said. At the time, Microsoft had been contracting with the Department of Defense for decades. It was also OpenAI’s largest investor, and had broad license to commercialize the startup’s technology.
That same year, OpenAI employees saw Pentagon officials walking through the company’s San Francisco offices, the sources said. They spoke on the condition of anonymity as they aren’t licensed to comment on private company matters.
Some OpenAI employees were wary about associating with the Pentagon, while others were simply confused about what OpenAI’s usage policies meant. Did the policy apply to Microsoft? While sources tell WIRED it was not clear to most employees at the time, spokespeople from OpenAI and Microsoft say Azure OpenAI products are not, and were not, subject to OpenAI’s policies.
“Microsoft has a product called the Azure OpenAI Service that became available to the US Government in 2023 and is subject to Microsoft terms of service,” said spokesperson Frank Shaw in a statement to WIRED. Microsoft declined to comment specifically on when it made Azure OpenAI available to the Pentagon, but notes the service was not approved for “top secret” government workloads until 2025.
“AI is already playing a significant role in national security and we believe it’s important to have a seat at the table to help ensure it’s deployed safely and responsibly,” OpenAI spokesperson Liz Bourgeois said in a statement. “We’ve been transparent with our employees as we’ve approached this work, providing regular updates and dedicated channels where teams can ask questions and engage directly with our national security team.”
The Department of Defense did not respond to WIRED’s request for comment.
By January 2024, OpenAI updated its policies to remove the blanket ban on military use. Several OpenAI employees found out about the policy update through an article in The Intercept, sources say. Company leaders later addressed the change at an all-hands meeting, explaining how the company would tread carefully in this area moving forward.
In December 2024, OpenAI announced a partnership with Anduril to develop and deploy AI systems for “national security missions.” Ahead of the announcement, OpenAI told employees that the partnership was narrow in scope and would only deal with unclassified workloads, the same sources said. This stood in contrast to a deal Anthropic had signed with Palantir, which would see Anthropic’s AI used for classified military work.
Palantir approached OpenAI in the fall of 2024 to discuss participating in their “FedStart” program, an OpenAI spokesperson confirmed to WIRED. The company ultimately turned it down, and told employees it would’ve been too high-risk, two sources familiar with the matter tell WIRED. However, OpenAI now works with Palantir in other ways.
Around the time the Anduril deal was announced, a few dozen OpenAI employees joined a public Slack channel to discuss their concerns about the company’s military partnerships, sources say and a spokesperson confirmed. Some believed the company’s models were too unreliable to handle a user’s credit card information, let alone assist Americans on the battlefield.

Don’t Risk Birdwatching FOMO—Put Out Your Hummingbird Feeders Now
Though most people associate the beginning of March with the hopefulness of spring and the indignities of daylight saving time, there’s another important event taking place yards all over the country: hummingbird season.
While many species of hummingbirds can be seen in regions year-round, others are migratory, and this time typically marks their return from wintering grounds in Central and South America. These tiny birds can lose up to 40 percent of their body weight by the time they arrive here after having flown thousands of miles, and since many flowers haven’t bloomed yet, nectar feeders can be a source of essential fuel.
Though I test smart bird feeders year-round, I don’t use hummingbird feeders as often as I should, as it’s imperative that they be cleaned and refilled with new nectar every two or three days (a ratio of 1:4 granulated sugar to water is best, and avoid any dyes or additives) to prevent deadly bacteria and mold, and I don’t always have the time.
But if you are going to invest the energy in maintaining a hummingbird feeder, right now is the best time, as you have a chance to see migratory species you might not otherwise encounter, such as black-chinned hummingbirds. A smart feeder helps you ID them, whether they’re stopping at your feeder on their way north or arriving at their final destination.
Birdbuddy’s Pro is the smart hummingbird feeder I recommend and use myself when I’m not actively testing. The app is easy to navigate and sends cleaning reminders, the built-in solar roof keeps the battery charged, and, unlike other feeders, only the shallow bottom screws off for refilling. No having to pour sticky nectar through a narrow opening, or turn a giant cylinder upside down and risk spilling.
Note that it’s not perfect; the sensor is inconsistent and doesn’t capture every hummingbird that visits, but for the camera quality (5 MP photos, 2K video with slow-motion, 122-degree field of view) and ease of use, it’s a foible I’m willing to put up with. If you already have another Birdbuddy feeder, the hummingbird feeder images and videos will integrate seamlessly into your app feed.
Right now, the feeder is 37 percent off on Birdbuddy’s website—a deal I usually don’t see outside of shopping events like Black Friday or Amazon Prime Day. Note that the feeder only runs on 2.4 GHz Wi-Fi, and while it is fully functional without a subscription, a Birdbuddy Premium subscription will let you add friends and family members to your account so they can see the birds as well. That’s $99 a year through the app.
