Guida alla scelta dell’aspirapolvere: quale acquistare?

Spread the love

Da quando esiste, l’aspirapolvere è diventato un elettrodomestico fondamentale per la vita quotidiana: semplifica davvero la vita, permettendo di pulire i pavimenti (e altre superfici) alla perfezione, senza fatica e in poco tempo. Ma come scegliere l’aspirapolvere ideale tra i tanti modelli presenti sul mercato?

Ecco, quindi, una piccola guida all’acquisto dell’aspirapolvere, con consigli e fattori da tenere in considerazione durante la scelta.

Aspirapolvere a carrello o scopa elettrica

Il primo grande punto interrogativo riguarda il tipo di elettrodomestico riguarda la scelta tra aspirapolvere a carrello e scopa elettrica. Ma qual è la differenza tra le due opzioni?

Possiamo dire che l’aspirapolvere a carrello è quello classico, che conoscono tutti, con il suo motore, il suo serbatoio e due ruote per poter spostare agevolmente l’elettrodomestico in giro per casa.

La scopa elettrica, invece, è un tipo di aspirapolvere verticale: ha la forma di una scopa e, grazie alla comoda presa per le mani, può essere maneggiata con grande comodità.

Quale scegliere tra le due dipende molto dalle proprie esigenze: l’aspirapolvere a carrello è più funzionale e pulisce in profondità, ma spesso fa rumore ed è decisamente più ingombrante. La scopa elettrica, al contrario, è la scelta ideale per le pulizie superficiali di natura quotidiana, è inoltre facile da riporre in quanto occupa meno spazio, perciò può essere la soluzione perfetta per chi non ha una casa grande o dotata di ripostiglio. Il marchio più noto in questo è sicuramente Dyson, con le sue scope elettriche di ultima generazione e dal design accattivante. È possibile trovare sul sito di Euronics tutti i prodotti Dyson per la pulizia dei pavimenti, con l’elenco di tutte le vantaggiose caratteristiche che hanno e spesso con offerte molto convenienti.

Aspirapolvere con o senza filo

Mentre l’aspirapolvere a carrello, di base, è sempre dotata di filo per la corrente, scegliendo la scopa elettrica, invece, ci si trova di fronte a un bivio: con o senza filo?

Questo elettrodomestico può infatti essere alimentato a batteria oppure a corrente, e quale scegliere dipende molto dalle dimensioni della casa in cui verrà utilizzato e dalla quantità di tempo che si dedica alle pulizie. Entrambe le parti in realtà hanno caratteristiche da tenere in considerazione.
L’aspirapolvere con filo è generalmente più potente, perciò ha prestazioni migliori a livello di pulizia. D’altro canto, però, il cavo può rappresentare un ostacolo e rendere meno comodi gli spostamenti tra una stanza e l’altra, e inoltre alcune scope elettriche hanno un filo un po’ corto: se si opta per questa tipologia, bisogna cercarne una che abbia almeno 5 metri di cavo.
L’aspirapolvere senza filo è più comoda da portare in giro per casa, dato che non presenta vincoli di alcun tipo, e solitamente è anche più leggera e maneggevole. Di contro, però, è spesso meno potente rispetto a quella a corrente, e inoltre vincola alla sua autonomia limitata. Se si scarica o comunque non si è caricata prima dell’uso, tocca aspettare.

Altre caratteristiche

Questi sono i fattori principali da guardare quando si compra un nuovo aspirapolvere, ma ci sono anche delle caratteristiche secondarie ugualmente importanti da mettere in conto. Per esempio, la potenza dell’apparecchio, che deve rientrare almeno tra i 1200 e i 2200 Watt, o il fattore rumorosità: più è silenzioso, più sarà piacevole, anche per gli altri presenti in casa!

Inoltre, alcuni hanno funzionalità extra che rendono l’esperienza d’uso ancora più completa, per esempio la luce che evidenzia il punto di pavimento su cui passare, mostrando chiaramente sporco e polvere: in questo modo, si ha la certezza di aver passato l’aspirapolvere in ogni punto e aver eliminato qualsiasi traccia di sporco.

  1. There’s a ‘ghost hurricane’ in the forecast. It could help predict a real one
    [url=https://lsm.kz/v-kazahstane-s-nachala-goda-vyyavili-22-finpiramidy]жесткое гей порно[/url]
    A scary-looking weather forecast showing a hurricane hitting the Gulf Coast in the second half of June swirled around social media this week—but don’t panic.

    It’s the season’s first “ghost hurricane.”

    Similar hype plays out every hurricane season, especially at the beginning: A cherry-picked, worst-case-scenario model run goes viral, but more often than not, will never come to fruition.

    Unofficially dubbed “ghost storms” or “ghost hurricanes,” these tropical systems regularly appear in weather models — computer simulations that help meteorologists forecast future conditions — but never seem to manifest in real life.

    The model responsible this week was the Global Forecast System, also known as the GFS or American model, run by the National Oceanic and Atmospheric Administration. It’s one of many used by forecasters around the world.

    All models have known biases or “quirks” where they tend to overpredict or underpredict certain things. The GFS is known to overpredict tropical storms and hurricanes in longer-term forecasts that look more than a week into the future, which leads to these false alarms. The GFS isn’t alone in this — all models struggle to accurately predict tropical activity that far in advance — but it is notorious for doing so.

    For example, the GFS could spit out a prediction for a US hurricane landfall about 10 days from now, only to have that chance completely disappear as the forecast date draws closer. This can occur at any time of the year, but is most frequent during hurricane season — June through November.

    It’s exactly what’s been happening over the past week as forecasters keep an eye out for the first storm of the 2025 Atlantic hurricane season.
    Why so many ghosts?
    No weather forecast model is designed in the exact same way as another, and that’s why each can generate different results with similar data.

    The reason the GFS has more false alarms when looking more than a week out than similar models – like Europe’s ECMWF, Canada’s CMC or the United Kingdom’s UKM – is because that’s exactly what it’s programmed to do, according to Alicia Bentley, the global verification project lead of NOAA’s Environmental Modeling Center.

    The GFS was built with a “weak parameterized cumulus convection scheme,” according to Bentley. In plain language, that means when the GFS thinks there could be thunderstorms developing in an area where tropical systems are possible – over the oceans – it’s more likely to jump to the conclusion that something tropical will develop than to ignore it.

    Other models aren’t built to be quite as sensitive to this phenomenon, and so they don’t show a tropical system until they’re more confident the right conditions are in place, which usually happens when the forecast gets closer in time.

    The western Caribbean Sea is one of the GFS’ favorite places to predict a ghost storm. That’s because of the Central American gyre: a large, disorganized area of showers and thunderstorms that rotates over the region and its surrounding water.

  3. Editor’s Note: Call to Earth is a CNN editorial series committed to reporting on the environmental challenges facing our planet, together with the solutions. Rolex’s Perpetual Planet Initiative has partnered with CNN to drive awareness and education around key sustainability issues and to inspire positive action.

    Crashing waves, glistening sea spray, a calm expanse of deep blue. These are the images that open “Ocean with David Attenborough,” the veteran broadcaster’s latest film. After decades of sharing stories of life on our planet, he tells viewers that: “The most important place on Earth is not on land but at sea.”

    The film — released in cinemas today and available to stream globally on Disney+ and Hulu in June — coincides with Attenborough’s 99th birthday, and describes how the ocean has changed during his lifetime.

    “Over the last hundred years, scientists and explorers have revealed remarkable new species, epic migrations and dazzling, complex ecosystems beyond anything I could have imagined as a young man,” he says in a press release. “In this film, we share those wonderful discoveries, uncover why our ocean is in such poor health, and, perhaps most importantly, show how it can be restored to health.”

    The feature-length documentary takes viewers on a journey to coral reefs, kelp forests and towering seamounts, showcasing the wonders of the underwater world and the vital role the ocean plays in defending Earth against climate catastrophe as its largest carbon sink.

    But the ocean also faces terrible threats. The film was shot as the planet experienced an extreme marine heatwave and shows the effects of the resulting mass coral bleaching: expansive graveyards of bright white coral, devoid of sea life.

    Extraordinary footage shot off the coast of Britain and in the Mediterranean Sea shows the scale of destruction from industrial fishing. Bottom trawlers are filmed towing nets with a heavy chain along the seafloor, indiscriminately catching creatures in their path and churning up dense clouds of carbon-rich sediment.

  4. Tree-covered mountains rise behind a pile of trash, children run through the orange haze of a dust storm, and a billboard standing on parched earth indicates where the seashore used to be before desertification took hold. These striking images, exhibited as part of the Right Here, Right Now Global Climate Summit, show the devastating effects of climate change.
    [url=https://kra34c.cc]kraken darknet[/url]
    The summit, held at the University of Oxford in the UK and supported by UN Human Rights (OHCHR), aims to reframe climate change as a human rights crisis and spotlight climate solutions. It works with everyone from policymakers to artists to get the message across.

    “Photographers document the human rights impacts of climate change, helping to inform the public and hold governments and businesses accountable,” said Volker Turk, UN High Commissioner for the OHCHR, via email. “The Right Here, Right Now Global Climate Summit shows the power of collective action — uniting storytellers, scientists, indigenous leaders, and others to advance climate solutions rooted in human rights.”

    Coinciding with World Environment Day on June 5, the exhibition — titled “Photography 4 Humanity: A Lens on Climate Justice” — features the work of 31 photographers from across the globe, all documenting the effects of global warming and environmental pollution on their own communities.

    Climate change disproportionately affects vulnerable populations around the world. Despite emitting far fewer greenhouse gases, low-income nations are suffering the most from extreme weather events and have fewer resources to adapt or recover.
    Photographs at the exhibition show the effects of desertification, flooding and plastic pollution. A black and white image shows the ruins of a house in West Bengal, India, sloping towards the Ganges River, with the owner sitting alongside. Riverbank erosion is degrading the environment and displacing communities in the area. Photographer Masood Sarwer said in a press release that the photo depicts the “slow violence” of climate change: “These are not sudden disasters, but slow-moving, relentless ones — shaping a new category of environmental refugees.”

    Another photo, taken by Aung Chan Thar, shows children fishing for trash in Inle Lake, Myanmar. The lake was once a pristine natural wonder but now faces the growing threat of plastic pollution. “This image of children cleaning the water symbolizes the importance of education and collective action in preserving our environment for a sustainable future,” he said.

    Organizers hope that the exhibition will help to humanize the climate crisis. “Our mission is to inspire new perspectives through photography,” said Pauline Benthede, global vice president of artistic direction and exhibitions at Fotografiska, the museum of photography, art and culture that is curating the exhibition at the summit. “It draws attention to the human rights issue at the heart of global warming, which affects both the world’s landscapes and the people that live within them.”

    “Photography is the most influential and inclusive art form of our times and has the power to foster understanding and inspire action,” she added.

  6. Scientists mapped what happens if a crucial system of ocean currents collapses. The weather impact would be extreme
    [url=https://pin-up-casino-online.kz/pin-up-app-download/]пин ап казино вход[/url]
    The collapse of a crucial network of Atlantic Ocean currents could push parts of the world into a deep freeze, with winter temperatures plunging to around minus 55 degrees Fahrenheit in some cities, bringing “profound climate and societal impacts,” according to a new study.

    There is increasing concern about the future of the Atlantic Meridional Overturning Circulation — known as the AMOC — a system of currents that works like a giant conveyor belt, pulling warm water from the Southern Hemisphere and tropics to the Northern Hemisphere, where it cools, sinks and flows back south.

    Multiple studies suggest the AMOC is weakening with some projecting it could even collapse this century as global warming disrupts the balance of heat and salinity that keeps it moving. This would usher in huge global weather and climate shifts — including plunging temperatures in Europe, which relies on the AMOC for its mild climate.

    What’s less clear, however, is how these impacts will unfold in a world heated up by humans burning fossil fuels.

    “What if the AMOC collapses and we have climate change? Does the cooling win or does the warming win?” asked Rene van Westen, a marine and atmospheric researcher at Utrecht University in the Netherlands and co-author of the paper published Wednesday in the Geophysical Research Letters journal.

    This new study is the first to use a modern, complex climate model to answer the question, he told CNN.
    The researchers looked at a scenario where the AMOC weakens by 80% and the Earth is around 2 degrees Celsius warmer than the period before humans began burning large amounts of fossil fuels. The planet is currently at 1.2 degrees of warming.

    They focused on what would happen as the climate stabilized post-collapse, multiple decades into the future.

    Even in this hotter world, they found “substantial cooling” over Europe with sharp drops in average winter temperatures and more intense cold extremes — a very different picture than the United States, where the study found temperatures would continue to increase even with an AMOC collapse.

    Sea ice would spread southward as far as Scandinavia, parts of the United Kingdom and the Netherlands, the research found. This would have a huge impact on cold extremes as the white surface of the ice reflects the sun’s energy back into space, amplifying cooling.

    The scientists have created an interactive map to visualize the impacts of an AMOC collapse across the globe.
