Funtime EG7980 Worlds Smallest Vacuum

Product Information

Simplified operation of a Knudsen pump that produces vacuum through thermal transpiration (Image: B. Dodson) Tom Wiberg (Sweden) built a motorcycle, which he named Smalltoe, that has a front wheel diameter of 16 mm (0.62 in) and a rear wheel diameter of 22 mm (0.86 in). In everyday use we felt that the best feature here is the built-in laser, which shines a green light on your floors so you can see dirt and dust that would otherwise be invisible. The V15 also comes with an LCD screen that displays the remaining runtime, and when used on Auto mode the cleaner conserves the battery by adjusting the suction power to suit the floor type and the amount of dust automatically. 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.

The say a picture is worth a thousand words, but if you want to know exactly how small this wooden spoon is, it measures at just is 4.5 mm (0.18 in) long. Next up is the world’s smallest newspaper, which in case you didn’t realize, is placed next to the coffee cup! 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. Households with pets will need a vacuum that can handle pet hair and if you want to use it to clean more than just floors, you’ll need one that converts to a handheld cleaner and comes with plenty of useful attachments. 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.But just how small is the world’s smallest spoon, bird or stop-motion film? (Hint: the stop-motion film is made using atoms, so it's pretty small!) Shark’s vacuum cleaners are more affordable than Dyson’s offering, but they can still match the stalwart when it comes to suction power. To keep the price tag low, Shark models are not as sleek and stylish as Dyson’s, and they’re often heavier too, but they do come with useful technology such as the ability to stop hair getting tangled around the brush air, and flexible wands to ensure you can clean in hard to reach places. All the debris was contained in a six litre Hepaflo bag which we found didn't fill up for a good number of weeks. To remove the bag, the top of the Numatic Henry HVR160 could be easily unclipped. No dust bunnies or debris escaped in the removal process which was a huge relief to our reviewer. We tested our Henry in a family home during various stages of renovation. From vacuuming-up flour and sugar, to accidentally broken glass and small chunks of rubble left over from an internal wall removal, we found that this canister vacuum cleaner was a really valuable addition to the home. We also learnt that the long, 2.5 meter hose could attach to either the crevice, dusting or brush and mattress tool, and reach up into the higher areas and / or get into some awkward spots. 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.

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 The Miele Triflex HX2 Pro is the brand's most powerful vacuum cleaner. It's a solid bit of kit, easy to manoeuvre and with the ability to detect when you transition from carpet to hard floor. However, the small dust canister and short battery life cloud what is otherwise a superb cordless vacuum cleaner. 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's not all good. The V15 Detect Absolute can be very noisy when running in full power mode, it only has an average sized dust canister and it's very expensive. But we think it’s worth the money if you want a top-of-the-range vacuum cleaner. 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.

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.
