These independent devices combine brushes with suction for optimal cleaning, use treads over wheels for better wall climbing, and operate efficiently in short cycles. Robot cleaners excel at daily maintenance of already-clean pools but cannot handle severely neglected pools with algae blooms or poor water clarity. In my (new!) role as the editor of PCWorld's growing home robotics category, I was only vaguely aware of robot pool cleaners . And when I did think about them, I assumed they shared many of the same limitations faced by robot vacuums .

Aiper's EcoSurfer 2 is a skimmer on the slow side, but it makes up for speed shortcomings with outstanding longevity. Roving pool surface skimmers are a surprisingly consistent category in the aquatic robotics space, typically featuring solar-powered, fully autonomous operation that you can drop in the pool and forget about for weeks. With its EcoSurfer S2, Aiper refreshes its skimmer design, boosts battery life, and improves intelligence. And while most pool owners can probably get by without a surface skimmer, it's a strong candidate for purchase if the surface of your pool is prone to collecting a lot of floating debris.

Send the pool guy packing. One of these robotic buddies can maintain your water quality instead. Cleaning swimming pools is not fun. I learned this simple logic as a kid growing up in and around pools--it's the only way to survive summer in Houston, Texas. Four years ago, I became a pool owner myself, and I found that the rule still holds. Jumping into the pool on a hot day remains a rare treat, but if the pool is filled with leaves and dirt, that treat becomes a lot less delightful. And when the thermometer is reading over 100 degrees Fahrenheit, the thought of laboring on the pool deck, scooping out debris with a net, is downright cruel.

I've recently introduced a few friends to the power of a great robot vacuum. One of my friends calls hers a marriage saver, while the other was both thrilled and horrified by how many stains the vacuum's AI found on her floors. Personally, my robot vacuums keep me from wanting to set the litter box on fire, since my cat is on a mission to create his own navigational trail of litter through my home. The best robot vacuums these days aren't just vacuuming your floors, nor are they blindly bumping around your house like they used to. These gadgets are mopping, scrubbing away stains, lifting themselves off of obstacles, and even reminding you to clean the dirtier areas in your home more frequently. A good robot vacuum can cost a pretty penny, but it doesn't have to, depending on what you're looking for. I've been testing every new robot vacuum I can in my three-story home filled with three adults, a preschooler, and a cat who's on a mission to get litter all over the house.

Strong coverage and a long run time make this pool-cleaning robot a compelling alternative to pricier models. Great performance for the price (assuming you can grab it on sale). Floats when cleaning is complete. Basket can be harder to clean than expected. Minimal intelligence (though it doesn't seem to need it).

Now outfitted with AI computer vision, Aiper's new pool cleaner can actively search for debris. AI vision helps to power excellent cleaning. Charging stand makes topping up the battery easy. Only spends 10 minutes at the waterline after each run before sinking. Cleanup can be a bit of a bear.

Managed a perfect cleaning record, if you leave it in the water long enough. Basket is quite difficult to clean. Must be retrieved with a pole when finished. In an aquatic world dominated by robotic pool cleaners that mostly look identical, a company called iGarden has been that breath of fresh air you take after reaching the water's surface. The company's pool cleaners have always featured designs that feel inspired more by high-end automobiles than underwater janitors, and with the new M1 series, its gear is sportier than ever.

Samsung Galaxy Unpacked 2026 is Feb. 25 A single collision could cause a cascading effect in orbit. Elon Musk's plan to launch millions of AI satellites could be disastrous for the planet. At the start of the month, Elon Musk announced that two of his companies -- SpaceX and xAI -- were merging, and would jointly launch a constellation of 1 million satellites to operate as orbital data centers. Musk's reputation might suggest otherwise, but according to experts, such a plan isn't a complete fantasy. However, if executed at the scale suggested, some of them believe it would have devastating effects on the environment and the sustainability of low Earth Earth orbit.

When a SpaceX rocket failure set the skies aflame over western Europe last February, no-one was sure if the debris was also polluting our atmosphere. Now scientists are directly linking the uncontrolled rocket re-entry to a plume of lithium measured less than 100km above Earth. It is the first time researchers have drawn a direct link between a known piece of space debris crashing to Earth and pollution levels. They warn that as SpaceX chief Elon Musk pledges to launch one million satellites in the coming years, this contamination could be the tip of the iceberg. The scientists were already investigating the problem of pollution from space debris when they realised a SpaceX Falcon 9 had failed in flight.

After a Falcon 9 rocket stage burned up in the atmosphere, vaporised lithium and other metals drifted over Europe. A SpaceX rocket that burned up after re-entering the atmosphere unleashed a plume of vaporised metals over Europe, a type of pollution that is expected to increase as spacecraft and satellites multiply. The upper stage of a Falcon 9, which is designed to splash down in the Pacific Ocean for possible re-use, lost control due to engine failure and fell from orbit over the north Atlantic in February 2025. We're finally solving the puzzle of how clouds will affect our climate People across Europe saw fiery debris streaking through the sky, some of which crashed behind a warehouse in Poland. Seeing the news, Robin Wing at the Leibniz Institute of Atmospheric Physics in Germany and his colleagues turned on their lidar, an instrument for atmospheric sensing.
