There’s also a number of different Henry versions, including the popular Henry Xtra, Henry Allergy, Henry Pet, Henry Eco and Henry Micro. There’s even now a Henry Cordless option too. 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.

To convert microhenries to another unit of electrical inductance, you need to multiply the value by a conversion factor.

If there’s one thing you expect from a Henry, it’s the cute face painted on the front of the iconic red body. It was a cute touch when Henry first launched, and it remains an enduring symbol that gives the vacuum cleaner a personality and life. It’s easy to love this vacuum cleaner. 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. 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.

Your Henry Vacuum Questions – Answered!

For people with pets in their homes both the Henry Pet and Harry would be better options than the original Henry, whilst George and Charles are also more favourable than Henry if you want a wet and dry vacuum.

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). A true design icon, the Numatic Henry is a vacuum cleaner that’s loved by thousands – including professional cleaners. And all for good reason: it offers a large capacity, it’s well priced, it cleans well, and has a reputation for lasting forever. Here on review I have the latest version of the Numatic Henry. It doesn’t stray too far from previous models, but has been designed to meet vacuum cleaner power limits. 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. Henry is the model that started it all – although he’s had a number of upgrades over the years. With a charming exterior and simple design, you could be forgiven for thinking it can’t compete with more expensive models. As we found in our Henry Hoover review, however, this is far from the case. 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.

Expressed in combinations of SI units, the henry is: [3] H = kg ⋅ m 2 s 2 ⋅ A 2 = N ⋅ m A 2 = kg ⋅ m 2 C 2 = J A 2 = T ⋅ m 2 A = Wb A = V ⋅ s A = s 2 F = Ω Hz = Ω ⋅ s , {\displaystyle {\text{H}}={\dfrac {{\text{kg}}{\cdot }{\text{m}} 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. which is the inductance of a conductor with one volt of electromotive force when the current is increased by one ampere per second. Yellow in colour, James has a slightly smaller bag capacity – eight litres rather than nine – than that of the Henry 200-11, his more famous family member. But in terms of performance there is no noticeable difference with the same motor size as Henry and Hetty; it’s once again a very capable machine built by Numatic International.

While this setup works well enough, experience has taught me that the various sections of the pole can become stiff and difficult to pull apart over time. To avoid this, I recommend pulling them apart at the end of each clean, and loosely rejoining them for storage. Powerful, easy to use and designed to last, this model is as enduring as the original. Note that the Hetty cleaner is exactly the same, but comes in pink. Design and Features The head of the family, Henry is certainly the most well known cleaner from the range. First introduced in 1981, Henry’s smiling face has been helping people to clean their homes ever since. Traditionalists will tell you this is the best Henry you can get, and if you’re looking for a reliable and affordable vacuum it’s hard to argue with this view. There’s actually two main models of this Henry, the Henry Hoover 160-11 and the Henry Hoover 200-11. The main difference between the two is the 160-11 has a bag capacity of six litres, whilst the 200-11 has a larger capacity at 9 litres.

A Bit About Numatic

The traditional cross shaped screwdriver that most of us have hanging around in the shed. This will be needed for removing the screws on older Henry Models. It will also come in handy if you need to remove the Carbon Brushes from your Henry Motor. 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 want the no-nonsense design of a Henry vacuum combined with the convenience of cordless, the HVB160 is an option to consider. It’s more expensive than the corded Henry and doesn’t have the longest run-time, but the strong suction and large capacity mean it’s much better suited to heavy cleaning than most cordless models. 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.

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. For the average home, the HZ series isn’t required as the standard HepaFlo bags + TriTex filtration is adequate for household dust and allergens. The HZ series is only necessary for industrial uses.​ Which is the Best Henry Hoover? Hetty smiles just as much as Henry, and in terms of performance is just as able. Hetty has a highly efficient motor, a 10 metre cable and rewind storage system, and comes with a host of useful accessories. Despite a significant reduction in suction power, improvements in efficiency means he remains a powerful and reliable vacuum cleaner, suitable for cleaning all types of services. Henry has also been built to be long-lasting, meaning he should last in your home for years to come. With a number of useful accessories included in the box, no cleaning job should be too hard. Like nearly all Henry vacuums the traditional Henry Hoover is corded and requires bags, so that’s something to bear in mind as he’ll need to be plugged in and have his bag changed from time to time.Then, multiply the electrical inductance measurement by the conversion factor to find the equivalent value in the desired unit of measurement. A conversion factor is a numerical value used to change the units of a measurement without changing the value. [1] 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. It’s also worth considering the compact versions of Henry vacuums. Many people don’t need the extra capacity provided by full-sized models. Summary
