Numatic Henry Micro HVR200M-21 Special Edition Vacuum Cleaner with Hairo Brush

Product Information

The HVR200-11 uses 620W of power, making it one of the more energy efficient models on the market. The motor also provides excellent suction and is highly durable, while the large 9 litre capacity means you won’t need to empty it often. Other features include TriTex filters, HepaFlo bags and a cord-rewind system. 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. 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). 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?

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.

Other Electrical Inductance Units

Then, multiply the electrical inductance measurement by the conversion factor to find the equivalent value in the desired unit of measurement. 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. 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.

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. Part of the reason for this power is that Henry doesn’t have any motorised tools for agitating dirt. Instead, it relies on good old-fashioned suction power to pull dirt out of carpets and off hard floors. I measure the raw power of all vacuum cleaners in AirWatts, which is a combination of airflow and suction power. This is a true measurement of power that lets us compare the performance of different models. A conversion factor is a numerical value used to change the units of a measurement without changing the value. [1]Henry Micro HVR.200M-11 has the same high specification as the standard Henry, but with added MicroTex filtration system. 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. 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. 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.
