The inductance of an electric circuit is one henry when an electric current that is changing at one ampere per second results in an electromotive force of one volt across the inductor: which is the inductance of a conductor with one volt of electromotive force when the current is increased by one ampere per second. The Henry Eco is very similar to other 6-litre Henry models, with the key difference being an energy-efficient motor – 420W compared with 620W. Reducing the motor power helps save on energy bills, although the suction power is slightly reduced as a result.

The female equivalent to Henry or also known as the female Henry Hoover, Hetty Hoover is another popular vacuum cleaner from the Henry family. A common question we see is what’s the difference between Hetty and Henry? The answer is not much at all. Apart from her appearance, Hetty is exactly the same vacuum so it’s not a case of Henry vs Hetty. The only real difference is that Hetty is pink compared to the traditional red. She also comes complete with eyelashes to add to her more feminine appearance. Hetty shares the exact same specifications as the Henry Hoover 160-11. The henry is a derived unit based on four of the seven base units of the International System of Units: kilogram (kg), metre (m), second (s), and ampere (A). As you can see there are not many tools that you need to repair your Henry. We can supply any part that you need. The key thing is to carefully follow any tutorial videos online or if in doubt ask an expert. There are also a few Henry groups on Facebook with members that know everything there is to know about repairing.If you decide Charles is the wet and dry vacuum for you, you’ll be getting a great all-in-one vacuum cleaner with plenty of bag capacity. The fact he’s also lighter than George means he’s easier to manoeuvre and carry around. Dust related allergies affect between 20% and 30% of the population, especially the very young and the elderly, this is where Henry Micro comes to the rescue. British manufacturer Numatic International has expanded the Henry Hoover range over the years to provide their first vacuum cleaner with some much needed company. There’s now fourteen different products in the Henry range, including a number of different Henry Hoover names which make up the Henry Hoover family. There’s Hetty, who’s also known as the female Henry Hoover, as well as James, Harry, George and Charles, the latter two which are wet and dry vacuums. Henry the Hoover has become a mainstay in British households since his introduction in the early 1980s, meaning the original Henry Hoover has now been cleaning UK households and workplaces for more than fourty years. Famed for this smiling face and red colour, Henry has become a firm favourite and a vacuum of choice. Henry Micro HVR.200M-11 has the same high specification as the standard Henry, but with added MicroTex filtration system.

With so much choice within the Henry Hoover family, it’s difficult to say which is the best Henry vacuum as it all comes down to what you require. The HZ series is built for industries where dust could be hazardous to health. These models have a HEPA filter, additional pre-filter and use Hepaflo bags, allowing cleaners to vacuum and empty the machine safely.

Aside from the motor and EcoBrush, the Henry Eco has similar features to many Henry vacuums. These include a six-litre capacity, bagged design, and a wide cleaning radius. It also comes with Numatic’s standard combi head for carpets and hard floors. With a six Litre capacity, Hetty is the same size as the Henry 160-11, but is smaller than the Henry 200-11 which comes in at 9 litres. So is Hetty smaller than Henry? It all depends on which model you’re comparing against.

I measured the Henry at 408AW, which makes it one of the most powerful vacuum cleaners I’ve tested; even more powerful than the Stihl SE 33 wet and dry cleaner. Opening the air valve fully only reduces power to 314AW, which is far more power than most of the competition. The good news is that the lower suction is partly counteracted by the EcoBrush tool – at least for smaller cleaning jobs. This is a small tool with a brush for agitating hairs and dirt from carpets, which improves cleaning performance. It’s not suitable for cleaning large areas though. If you’re looking for a straightforward cylinder vacuum that won’t let you down, the Henry is a great choice for carpets and hard floors. While it can be unwieldy to use on stairs and doesn’t have many advanced features, it has excellent filtration, strong suction power and provides great value.

Aside from the cordless design, it has a 6 litre capacity (which is huge for a cordless), power boost mode, and HepaFlo bags. Like other Henry models, it comes with several tools, such as a crevice nozzle and dusting brush.​ The bagged design also means it could be a good choice for those with allergies. The henry (symbol: H) is the unit of electrical inductance in the International System of Units (SI). [1] If a current of 1 ampere flowing through a coil produces flux linkage of 1 weber turn, that coil has a self inductance of 1 henry.‌ The unit is named after Joseph Henry (1797–1878), the American scientist who discovered electromagnetic induction independently of and at about the same time as Michael Faraday (1791–1867) in England.

Another factor that allows James to be smaller is the cable tidy that can be found on the top of his head, which means you can manually wind the cable by hand. Where James stands out over the rest of the Henry Hoover range is the unique caddy tray that can also be found on the top of his head, providing a great storage place for his attachments that includes the crevice tool and the upholstery brush. However, Charles is quite a bit lighter than George and doesn’t come with as many accessories as his older brother. The main thing missing with Charles when compared to George is the extra carpet / upholstery cleaner. If this is something you require, then you’d be better off going for George, but if it’s something you don’t feel you need, then Charles is the man for you as he’s generally cheaper than George and lighter.That’s a difficult question, as the best Henry Hoover depends on your requirements. For everyday vacuuming, we still think the standard Henry is the best choice. It’s powerful, has a huge capacity and is now much more energy efficient. The exception is if you have pets. In this case, the Harry is a great choice due to its active charcoal filter and pet tool.
