And it’s optional to mount on top and it projects the air out towards the memory and VRM components. We also looked at the company’s thermosiphon, which was briefly shown at Computex last year. It is a 2-phase thermosiphon, which means that it does a phase change. This makes it comparable to a heat-pipe in a way. We also got to see a bunch of different types of cold plate designs.We also got another look at the Noctua x Antec Flux Pro case, which we previously covered at Antec’s booth.G2 FansNoctua showed off its 120mm G2 fan, which also appears in the shroud top of the Antec Flux Pro case. A couple things have changed about the fan, which include the RPM offset being a little different.Grab a GN Soldering & Project Mat for a high-quality work surface with extreme heat resistance.

In the old days, they worked with Corsair, NZXT, and basically everyone’s stuff.The landscape has diversified a bit. Apaltek has gotten really big as a supplier. For as much s*** we’ve given Asetek over the years, in our experience, they’ve had fewer widespread failures of gunk buildup compared to competing solutions. Noctua MouseWe don’t cover mice, but Noctua also showed off a mouse with a small fan built into it. Noctua's Jakob Dellinger Interview Visit our Patreon page to contribute a few dollars toward this website's operation (or consider a direct donation or buying something from our GN Store!)

Ecovacs Deebot X9 Pro Omni robot vacuum review: superior mopping skills MSRP $1,600.00 Score Details “The Ecovacs Deebot X9 Pro Omni features one of the best mopping systems ever used in a robot vacuum.” Pros Innovative mopping system Retractable brushes and mops Self-cleaning dock Anti-tangle vacuuming Cons Expensive Too tall to fit under furniture Ecovacs launched the Deebot X8 Pro Omni earlier this year. Featuring a unique roller mop system, it offered one of the best mopping performances we’d ever seen in a robot vacuum. Now, a few months later, the company has already launched its successor — the Ecovacs Deebot X9 Pro Omni. It takes everything we love about the X8 and makes it better, including a new mop-lifting system, enhanced vacuuming system, and a fantastic anti-tangle design that eliminates hair and string from clogging up its brushes. Recommended Videos If you’re looking for a robot vacuum to thoroughly clean hard floors, you can’t go wrong with the Ecovacs Deebot X9 Pro Omni. It’s not perfect, but aside from a few minor complaints, the expensive X9 Pro Omni should make a premium addition to any smart home. One of the best mopping systems ever Jon Bitner / Digital Trends I’ve tested dozens of robot vacuums over the years, and I can say without a doubt that the Ecovacs Deebot X9 Pro Omni offers one of the best mopping experiences on the market. Known as “OZMO Roller Mopping Technology,” it’s essentially a giant roller brush on the bottom of the robot. A series of sprayers are constantly rewetting the mop to ensure a consistent clean across your floors, while a scraper is used to pull dirty water off its surface. The end result is remarkably shiny floors. Combined with its ability to apply 3,700 Pa of pressure and roll at speeds up to 220 rpm, it eliminates just about any stain or spill it encounters. Ecovacs also outfitted the X9 Pro Omni with some cool bonus features. The first is a triple-lift system, allowing the mop, main brush, and side brush to retract depending on the task at hand. When a spill is detected, both mops will retract, ensuring they stay clean. When carpet is detected, the mop will retract, ensuring your floors stay dry. Better yet, the robot offers a “Carpet First” function — meaning it’ll zip around your home and vacuum with a dry mop before starting the wetting and mopping process. When all of this is taken together, the end result is a robot vacuum perfect for cleaning hard floors. It’s also great that it can traverse carpets with dry mops — though it would be even better if it could automatically detach its mop and leave it in the base station when vacuuming. It’s a feature some competitors are starting to use to great effect, as it ensures your mops aren’t touching carpet at all. Vacuuming and self-cleaning Jon Bitner / Digital Trends Oddly enough, the X9 Pro Omni offers less suction than the older X8 Pro Omni. The previous robot packed in 18,000 Pa — the X9 Pro Omni shifts it down to just 16,600. However, its vacuuming performance remains about the same (if not better), thanks to the inclusion of BLAST technology. BLAST is shorthand for “Boosted Large-Airflow Suction Technology,” and it works via a combination of suction and maximized airflow. The idea revolves around using additional airflow to knock loose dust particles and other debris, which can then be suctioned up without requiring as much force. In practice, we’ve found the system to work incredibly well. Along with handling dust and small particles, it picks up clumps of dirt and larger objects without much trouble. It also leaves fantastic lines on plush carpet — giving your home a “just cleaned” appearance most shoppers will appreciate. The side brush doesn’t swing out like some competitors, but it still did a great job of tackling corners and tight spaces, thanks to its impressive navigation skills. Best of all, you can use onboard AI to allow the robot to determine all the best settings for a superior cleaning. There are dozens of ways to manually customize its performance via the mobile app, but I’ve found letting the robot do its own thing often results in the best clean. Jon Bitner / Digital Trends Once a cleaning cycle is complete, the robot heads back to its dock to recharge and clean itself. The docking station washes the mop with hot water, dries it with hot air, and can even dispense a cleaning solution into the robot’s water tank for a better mopping experience. The onboard dustbin will also be siphoned off into a larger dustbag in the docking station, allowing you to go 90 days before needing a replacement. Finally, the docking station will clean itself, washing away any gunk removed from the robot during the cleaning cycle. Pretty much all of the maintenance tasks are taken care of for you. You’ll just need to monitor the clean and dirty water tanks, and perform a more thorough washing tray cleaning every 150 days. As far as robot vacuums are concerned, that’s a huge win for autonomy. Verdict There’s a lot to love about the Ecovacs Deebot X9 Pro Omni, and it’s an easy recommendation for most shoppers. If your home is largely composed of hard floors, it’s an even easier choice. However, there are a few limitations to consider. For one, it can’t leave its mop behind in its docking station. Yes, it will raise it while traveling on carpet, but most shoppers will likely find the auto-detachable mops of the Roborock Saros 10 to be a more elegant solution. The robot is also quite large. At 3.8 inches tall, it’s almost a full inch taller than some competitors. So while it’s small enough to clean under most furniture, smaller nooks and crannies will be too tight for the X9 Pro Omni to fit underneath. These are minor complaints on an otherwise stellar device. The Ecovacs Deebot X9 Pro Omni proves the brand has what it takes to stick with the leaders of the segment, offering a superior mopping experience matched by few rivals. Add in the effective BLAST vacuuming system, self-cleaning dock, and impressive onboard AI, and you’ve got one of the best robot vacuums of 2025.

As long as you keep up with regular cleaning and follow the recommended maintenance tips we’ve rounded up here, you shouldn’t have any issues.Is it expensive to maintain quartz countertops?According to Booth, not in the slightest. “Quartz is nonporous,” she says. “So there is no need to routinely seal the surface.” In comparison, countertops such as quartzite, granite, and marble do need to be routinely sealed to maintain their appearance. That being said, you may face some hefty costs if you don’t follow the general recommendations for preventing long-term damage to your countertops, like avoiding extreme heat or scratching them with knives or other sharp objects.Can you use Clorox wipes on quartz countertops?The short answer? Probably not. The long answer? Right this way. Many Clorox wipes are actually bleach-free. You can use them occasionally for deep cleaning, but they shouldn’t be the first thing you grab. You shouldn’t be using Clorox wipes daily, or even often, on quartz countertops because they have citric acid, which can be very harsh on your counter. Long-term use could lead to discoloration of your quartz surface.Can I use Windex on quartz countertops?Windex is considered a base and has a pretty high pH level, which means it could be damaging to quartz. Some professionals say it’s okay to use in small quantities, while others warn against it. For the safest and most sure option to keeping your quartz clean, skip Windex and opt for a mild cleaner like dish soap.In general you should be very careful when using this cleaner. Some Windex formulas rely on the cleaning agent ammonia, which can create very harmful mixtures when combined with bleach—like sodium hypochlorite. This combo can create chloramine vapor, a noxious fume that can irritate your eyes, nose, throat, and airway. In some cases, large quantities can even be fatal.What should you not clean quartz countertops with?In addition to avoiding Clorox and Windex, you shouldn’t use anything with abrasive or harsh chemicals to clean your stone countertops. That means skipping bleach, degreaser, oven cleaner, scouring pads, or other alkaline cleaning solutions or disinfecting formulas with high pH levels. These highly acidic cleaners will damage the countertop and ruin its integrity. If you‘re using them on other items, make sure the spray doesn’t land on the stone surface.To prevent stubborn gunk from building up, it’s best to stick to mild detergents, soapy water and gentle cleaning products. Keep up with a daily maintenance routine rather than trying to address the dirt with a deep cleaning method or harsh cleaners later on. If you happen to have accidents involving nail polish or permanent marker stains, try DIY methods, like using watered-down lemon juice or a dose of rubbing alcohol in a spray bottle.It’s also important to keep quartz surfaces safe from hot pans because they are sensitive to extreme heat. You can use trivets and hot pads to protect granite countertops (which have quartz) from off-the-stove dishes. For food prep that uses sharp objects, especially knives for chopping, cutting boards protect the surface from scratches and divots. And it’s always best to keep coasters around for hot mugs.How to remove stubborn stains from quartz countertopsTo prevent stubborn gunk from building up on quartz countertops, it’s best to stick to mild detergents, soapy water, and gentle cleaning products. Keep up with a daily maintenance routine rather than trying to go back in with a deep cleaning method or harsh cleaners later on. As a general rule of thumb for any stains you come across, Booth recommends first trying mild cleaning solutions before reaching for the stronger, harsher options; it’s better to start slow than risk causing irreversible damage. “I suggest starting with mild dish soap and a microfiber cloth,” she says. “Rub the stain in circular motion and then rinse with clean water.”

The newly unveiled Deebot X9 Pro Omni promises less gunk and less smearing.
