It was created by Gerard Jenkins-Omar and Stephen Robson (both UK) and was measured in Rotherham, UK, on 24 September 2016. Shark vacuums tend to have larger dust canisters than most of Dyson’s models, but the battery doesn’t last as long. So are they better? It very much depends on the layout of your home and your budget. Read our Shark vs Dyson article for a more in-depth look at the two floor-cleaning brands. How often should you vacuum? Built using the smallest commercially available steel ball bearing, also created by MinebeaMitsumi Inc, the spinner weighs just 0.027 g (0.00095 oz). To help appreciate the magnitude of the task DARPA had posed, consider the Creare Engineering miniature turbo/drag pump, considered to be the world's smallest practical turbo pump produced by conventional machining tools. The pump is some 3.8 cm in diameter with a length of 8 cm, making it slightly larger than a D-cell battery. It weighs about 150 g (5.3 oz), and can reach an ultimate pressure of a few uPa. The pumping speed is four liters/second at a rotor speed of 200,000 rpm, and consumes about 2 W in doing so. This pump needs to be followed by a roughing pump as it cannot pump against atmospheric pressure. DARPA sought a vacuum system no bigger than a US penny that is able to produce a vacuum of less than 100 microPascals (uPa, a billionth of atmospheric pressure) in a vacuum chamber with at least a cubic millimeter of volume (about the size of a grain of coarse sand). The vacuum system was to use less than a quarter of a watt, and contain instruments to accurately measure the pressure in the chamber.

IBM Research Laboratories in San Jose, California, USA managed to combine science and art by breaking the record for the smallest stop-motion film. It comprised of 242 individual frames with a frame size of only 45 nanometres by 25 nanometres (45 x 25 billionths of a metre). How the film was made In a nutshell, Dyson vacuums are more expensive but this ensures you get a vacuum cleaner that’s extremely powerful but still lightweight and easy to maneuver around your home. Dyson vacuums are stuffed with cutting edge technology too, from lasers that highlight hidden dust to innovative floor heads that can be moved in any direction. If you prefer a cordless model, they also come with long-lasting batteries too. It measured at just 54 mm (2.12 in) long - you can see it in the image above next to a standard sized business card. And if you have hard floors, look for a vacuum cleaner that comes with a dedicated cleaner head, which has a softer brush roll to ensure the flooring isn’t damaged when vacuuming.The mini newspaper is an edition of the newspaper Terra Nostra (Portugal) and measures at 18.27 x 25.35 mm (0.72 x 0.99 in). The outstanding newspaper weighs at 1 g only. Guinness World Records titles has always been known to highlight the most impressive things from all across our planet such as the fastest, the heaviest, the biggest or the longest. Desulforudis audaxviator was found 2.8 km beneath the Earth’s surface in the Mponeng gold mine, South Africa.

However, it is a bulky appliance so it may be a problem to store. We were also disappointed there were no LEDs on the floor cleaning head - a feature offered by some vacuums in this list - which makes it easier when cleaning in dark spaces under furniture. The world's smallest mobile nightclub is "Club 28", which is a box measuring only 2.01 m (6 ft 7 in) high, 0.92 m (3 ft) wide & 1.53 m (5 ft) deep. While the Game Boy was loved for its small size, Jeroen Domburg (Netherlands) took things to another level when her created the smallest Game Boy ever.We test all the best vacuum cleaners in our homes, so we know how well they perform in the real world –a world where kids and pets and partners create all kinds of messes for these cleaners to cope with. We test their cleaning power, of course. But we also test to see how comfortable they are, how heavy they are to hold and whether they can reach places that other cleaner can't. As you'd expect from Miele this is exceptionally well made and feels like it'll last for decades. Which sadly is more than we can say for the battery: we ran out of power before we completed a full clean of our home, so we were glad for the included second battery.

This little Game Boy fits on a key chain and boasts an impressive selection of the original Game Boy games.

Since the overall system still wants to be in mechanical equilibrium, some of the gas molecules move from the hot chamber into the cold chamber. If you then close a valve between the hot and cold chambers, and let the temperature of the hot chamber return to the original value, the pressure in the hot chamber will be less than before the heating-cooling cycle was performed. The pair of chambers and appropriate valves acts as a vacuum pump. The micro machine has a wheelbase of 80 mm (3.14 in), a seat height of 65 mm (2.55 in), weighs 1.1 kg (2.4 lb) and is powered to a top speed of 2 km/h (1.24 mph) by its 0.22 kW (0.3 hp) engine. This bagged, corded cylinder vacuum cleaner is a DIYer's best friend. No matter how much mess has been created, and regardless of (pretty much) what that mess is, Henry can handle it.

Dyson's V15 cordless vacuum cleaner really is its most impressive yet. It’s more powerful and cleans even better on all surfaces, yet still lasts up to 60 minutes between charges - the same battery life offered by its predecessor, the Dyson V11, which has the same price tag. The 60 seconds film titled "A Boy and his Atom" tells a short story of a boy named Atom playing with a ball.We've tested all the brands, from big names such as Miele and Dyson to lesser known names like Roidmi and Shark. So we can say with confidence that the vacuums you see here are the best vacuums of every kind, and for every kind of home. If you have a specific type of cleaner in mind, we also have detailed guides covering specific categories –so we have a great guide to the best robot vacuums and a guide to the best cordless vacuums too. As we’ve mentioned already, knowing which type of vacuum to choose can end up leaving you confused. However, considering the type of property you have will help you decide. Battery life aside this is a very powerful and capable cleaner, and the automatic floor detection is useful and works very well. It's a little pricey compared to some rivals but it's a premium product and Miele tests all its products with the equivalent of 20 years of intensive use, so it's built tough and should last forever.
