![]() Scrubber dryers are like cars – they all work the same, yet not every model is suited to each area of application. This is why loosened dirt is collected by, for example, Kärcher's wet and dry vacuum cleaners afterwards. Scrubbers on the other hand do not have a turbine or a squeegee. Thanks to the turbine's suction power, the dirty water is then absorbed by the squeegee and collected in the dirty water tank. The rotation and contact pressure of the brush work together to remove dirt. The cleaning solution is mixed either in the fresh water tank when cleaning agents are added to it or, in the case of automatic dosing systems, just in front of the brush head itself. “Not all microbes are major transmission risks, but most of them can be obviated by just washing your hands.All modern scrubber dryers with a roller or disc brush head essentially work in the same way. Many of them aren’t harmful to humans, he said, and transmission risk from your phone is probably low. “It’s using semi-truthful scientific facts out of context to build a narrative to sell a product.”Īnd trying to get rid of all the microbes that could be present on your phone isn’t a worthwhile goal, Adalja said, because it’s impossible microbes are everywhere and on every surface or object you could touch - even on your body. If you took a tiny pinch of yogurt and put it on a plate, you would have hundreds of microbes, and nobody is going to say that’s more dangerous than a toilet seat,” she said. But the presence of microbes doesn’t mean anything in terms of whether it can make you sick, said Paula Cannon, professor of molecular microbiology and immunology at the University of Southern California’s Keck School of Medicine. Adalja, an infectious-disease physician and senior scholar at the Johns Hopkins Center for Health Security.Ī common claim (often repeated by companies selling cleaning devices) is that phones are much dirtier than other household objects, such as toilets. The question is: ‘Does it actually translate into a health benefit?’ ” said Amesh A. ![]() ![]() “It’s not a question of whether the UV works that’s not the issue. The real question, Reingold and other experts say, is whether these devices are necessary to prevent transmission of viruses - and they said no. (The study in the Journal of the American Association for Laboratory Animal Science found that the most bacteria was left behind in the crevices in between the tablet’s case and screen.) Look for a device with a sensor or timer that shuts off the device when it’s done, so you’re not exposing your eyes or skin to the light, Linden said. The devices are best used on hard, nonporous objects with flat surfaces. Wands won’t be as effective, because they don’t concentrate the light on the objects and could also carry more risk, because the light is not contained. If you do purchase a gadget sanitizer, Linden said, get an enclosed-box model, which can concentrate the light safely and effectively, rather than a wand model. If you’ve been considering buying a UV phone sanitizer, consider this: Although the experts we spoke to say that this type of device works if it produces UV-C light in the appropriate dose, they still don’t recommend buying one.Įnclosed models will concentrate the UV light on the device you're trying to sanitize. Personal UV sanitizing devices can run from as little as $10 for a wand-style model to more than $100 for an enclosed box that will also charge your phone, with room to spare for your wallet and keys. Air purifiers saw a bump as more was learned about how the virus spreads.Īnd one long-used but perhaps lesser-known disinfecting technology - ultraviolet light - got a big boost as consumers sought to protect the one item they touch the most: their phone. Face masks, first a DIY project, are now a staple for seemingly every brand. Disinfectant wipes were a hot-ticket item for most of 2020. Almost a year into the coronavirus pandemic, the United States is a little cleaning obsessed.
