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. 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}} 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. 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.

where V( t) is the resulting voltage across the circuit, I( t) is the current through the circuit, and L is the inductance of the circuit. The standard Henry and Hetty vacuums are great machines that will get almost any vacuum job done with little fuss, but there’s now lots of other options, some of which may be more appealing depending on what you need. 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. 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.

What else should I know about the Henry Vacuum Cleaner Range?

The microhenry is a multiple of the henry, which is the SI derived unit for electrical inductance. In the metric system, "micro" is the prefix for millionths, or 10 -6. Microhenries can be abbreviated as μH; for example, 1 microhenry can be written as 1 μH. How Much Is a Microhenry? Joe is the creator of Inch Calculator and has over 20 years of experience in engineering and construction. He holds several degrees and certifications. 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? 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.

There’s also a number of Henry models with their own selling points, such as the Henry Xtra – a slide upgrade on Henry due to his extra tools – Henry Allergy, Henry Wash and Henry Micro. And then there’s the wildcard Henry Cordless option, the only cord-free vacuum available from the Henry range. 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.

How Much Is a Microhenry?

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:

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 conversion factor is a numerical value used to change the units of a measurement without changing the value.
