vacuum cleaner new
john d hamilton
the fan on a household Hitachi CV-SF8 vacuum cleaner.
http://tinypic.com/view.php?pic=11rxdm0&s=4
Immediately behind this sits a plastic frame with a nylon fine mesh filter
and sitting in this frame is a black high density sponge filter. (doing a
search on this sponge filter, it's called a Mesh-Urethane filter).
http://tinypic.com/view.php?pic=6gv5tl&s=4
This Mesh-Urethane filter is on the *right* side of this photo, the black
one on the left is the reverse of the very thin plastic type filter referred
to above.
This Mesh-Urethane filter really restricts the air flow. Its a bit better
when I wash it out under the tap with soap and water but soon seems to clog
up again. I find it works quite well if I relace it entirely with a piece of
soft tissue toilet paper, and keep changing the paper and all the debris
that builds up behind it.
Now the question here is what exactly is this very thin plastic type filter
(if indeed it is actually a filter) doing? It's the one on the left in the
second photo. It seems to have microscopic slits in its surface, but when I
wash it, it wont pass water through it, which surely it would if its some
kind of filter? It's a thin flexible piece of plastic sheet, and seems
really strong. Almost like a sheet of carbon fibre.

New vacuum designs come along like new car models. They keep changing
things in the hope of generating marketing appeal. A vacuum still has
the basic purpose of picking up dirt. The bagless vacs use a great
deal of extra air processing designs to catch more dirt. They
include heppa filters, dog hair filters, and bacteriacide filters.
That black filter looks like carbon to treat pathogens. The white one
is like a pre-filter to catch higher micron debris. Neither one is
designed to process much air volume. Don't be fooled by the fact that
a filter won't pass water. This is not a wet vac. There are times when
you can modify a machine to suit your needs better, but first assume
that Hitachi paid a staff to design this thing without using Charmin
as the filter media.
The bottom line is that if it picks up your dirt better with that
restriction removed, go ahead and use it that way.

There's a punchline in there somewhere. How about the wife?

The first stage is supposed to get rid of almost all the dust by
centrifugal force. If the air then clogs a filter frequently, I wonder
if something is wrong with the first stage.
Andrew Gabriel
If you want a cyclone cleaner that works, you're really going
to struggle with anything other that a Dyson. Dyson have a stack
of patents relating to designing cyclones small enough to be part
of a vacuum cleaner which actually work, that's it's pretty
impossible for other manufacturers to come close. His original
dual cyclone patent expired which is why you now see other
manufacturers doing those, but they're stuck with following all
his advances 25 years behind.

People should AVOID Dyson vacuums unless they like pissing their money
away. They work no better than any other cyclone vacuum available at
Walmart or Target. No difference. No Advances. Simple 19th century
soot collection.
They are, however, have the unique benefit of being possessed of superb
design, and are, as such works of functional art worthy of buying simply
for that reason. But a frugal person would avoid Dysons as if it were a
plague carrier. We won't mention the abominable ergonomics of some of
his designs, as they are self-evident and glaring. Dyson = Hype.
Save money-- buy a Hoover or a Bissel or a Snorch.

If it wasn't for Dyson we would still be getting ripped off for hundreds
of dollars of bags and filters a year and putting up with poorly
designed crap that blows most of the dust back into the air along with
the mould and crap that grows inside the non replaceable filter paths
inside. Look how much effort the American vacuum manufacturers put into
killing the cyclone vacuum market in America only to have their market
share destroyed once people found out how good they are and how long
they last.
If you think a Dyson is so bad , Hoover your carpets with the best vac
you can find, then go over it again with a Dyson, you will be surprised
how much extra crap they will pick up. I expect you think that piece of
crap Oreck sells is a good deal.

We had a vacuum salesman call a couple of years ago, and hubby set up
appt. for demo. Don't recall the brand, but it was very expensive.
Salesman did the filter paper trick to show how dirty the carpet was.
When he finished his talk, I asked him for a clean piece of filter
paper. I put the clean filter paper over the nozzle of my OLD
Electrolux; got the same result as his fancy new machine.
Archon
what you say.
Bags were awful, they ripped, blocked, smelled bad and the phony ripoff
copies were everywhere.
I bought a Dyson DC01 back in early 90's in the UK, brought it over to
the States in 2001, run it off my 240v supply, never broke down, cleans
as good as new, only thing I've ever replaced was the brush bar.
I went through 2 Hoovers, a Panasonic, (that lasted about 3 months
before the bearings on the brush bar burned out with wrapped hair in the
3 years previous to buying the Dyson.

The cyclone action only moves air in a circular motion inside a chamber.
The dust and other small particles are actually caught by the replaceable
filter traps in the path of the air flow. The cyclone does not drop its
dirt payload on its way round the vacuum cleaner. The dirt falls off the
filter when it reaches a weight heavy enough to allow it to fall off, or you
take the filter out and clean it before it reaches that stage.
How the cyclone action works is very simple. You make a vacuum cleaner as
normal, with a lower pressure atmosphere action at the head unit (the bit on
the carpet that picks the dirt up). You draw the air / dirt mixture into a
chamber that contains a tapered tube. The top of the taper is four times
the diameter of the bottom. When air is blown across the top of the tapered
tube (commonly called the wide end), it causes the air in the tube to spin.
When the air begins to spin, it creates areas of high and low pressure in
the chamber surrounding the tube. The dirty air being sucked in is at high
pressure near the top of the cyclone chamber. Once the spin motion starts,
the air lower down in the cyclone chamber goes to a lower pressure, where
the dirt is to heavy to be lifted back out by the air motion (commonly known
as the narrow end of the tube). So the dirt stays in the chamber. Well,
most of the heavier bits do. The tiny particles are caught by replaceable
filters that you have to buy seperately, just like the old style bags.
The filters need to be replaced just as often, if not more frequently, as
would have replaced a bag in any other vacuum cleaner. But the big bits of
crap getting caught in that chamber, really looks impressive, don'it. Where
it's all actually a load of ballox.
It's not rocket science.

You are describing a (non-cylone) canister vacuum cleaner (such as
a Henry or a Vax in the UK), or something that might have been
marketed to make you think it was a cyclone, but doesn't actually
use cyclonic separation (of which there are a number of non-Dyson
products made to look a bit like Dysons).
> It's not rocket science.
No it's not, but you might want to go and read up on cyclonic
separation, so you understand the difference between that and what
you posted.
Archon
I think not, the principle was developed I believe from watching
industrial silo dust removal. The filter does not work that hard, if as
another poster stated, you use it for garage/plaster/woodwork sanding
clean up with very fine dust, the dust does not get to the filter, it
stays in the washable bin (another Dyson innovation).
And Yes, American household appliances, from vacuums to kettles to power
tools are dramatically underpowered.

Here's a link to the Wiki Pages
http://en.wikipedia.org/wiki/Cyclonic_separation that describes how a
cyclone works. I think it is as close to what I explained as nought in it.
And, honestly, I wrote all my rant from memory.

A given cyclone design will catch particles down to a certain size
because it's a particle's mass that causes it to stick to the side
instead of exiting with the air. That's why you need the paper filter.
Probably the cyclones in some vacuums won't catch particles as small
as other cyclone vacuums.
I have a cheap vacuum cleaner that uses a filter I can knock clean when
I empty the bin, followed by a paper filter. I've never had to replace
the paper one.

Some UK kettles have 3kW elements, while some US kettles have 1.75kW
elements. So it takes 45 seconds to boil a cup of water in the US and
26 seconds in the UK.
Standard US outlets are for 15 amps. Most homes use 20-amp wiring. If
enough Americans were impatient, there would be 20-amp kettles, which
could heat the water in 33 seconds.
It appears that the most common size of Dyson vacuum in the UK is 1400
W. Some US vacuums use roughly that much. If US vacuums really aren't
as good, the problem must be something else.

Yep - but some are better sucking suckers than others.
Let's hear it for Sebo....
Our 1995 Sebo is still going strong. All the tools "on board", mega-easy to
change bags (and they're cheap enough on ebay), mega-long mains cable,
quickly dismantleable (though not necessary), and no dust containers to wash
out.
The only maintenance it needs? Every couple years or so, we unclip the
roller-brush and remove the long threads.
Yep - Sebo every time....

A friend o'mine bought a super-dooper HD Whirlpool washing machine to handle
the load from her incontinent, disabled kid. A long time researching and
taking sales advice.
The machine was HUGE, seemed built like a tank. It was heavy and gawdawful
expensive and could take a king-size heavy-tog quilt with room to add,
probably, a sofa and the family dog. It had great, industrial type styling
and we had a celebration party 'cos we were all so impressed. (yes, really.
loads of people watching a washing machine with glasses of bubbly... sad but
true.) Everyone thought it was a 20yr investment.
The trouble was that NOTHING came out clean. The KS quilt, clothes,
underwear, ordinary shirts... everything. Had an engineer out to check it. It
was up to spec. No faults anywhere - except in the design for performance.
She tried every recommended combination of detergent, heat, agitation, voodoo
incantations, payload size... No matter what, everything was dirty and
covered with felt-ish fluff. The manual even referred to this as a known
"feature" of this type of machine and called it something like "nubbing" or
"bobbling" or whatever, saying it may be an initial problem with some fabrics
and could be cut down by using their speciall no-nubbiing, anti-bobbling
zero-beading chaff-stopping detergent. Very expensive special detergent, that
is. The very expensive special detergent was duly bought, and used. No
improvement in the bobble-chaffing nub beading at all, and the clothes were
still stained, dirty.. and covered in all this raised pile stuff.
The machine was great at accelerating wear in its payload but lousy at
cleaning.
She got her money back as the machine was argued not to be of merchantable
quality - i.e. it didn't (couldn't) perform its intended task of being a
washing machine.
This, apparently was America's Finest - at least as far as those of us in the
export slipstream are aware.
This begs all sorts of questions..
er.. Do you guys in the USA who have carpet cleaners that don't clean, and
washing machines that don't either... er, <ahem>... well. what I mean is....
I hope that showers work O.K. at least.. :-)
Maybe the domestic machines are different.
Personally, I love USA engineering. I prefer over-robust materials - cast
iron, milled alluminum (!) bolted together with proper fasteners - to the
oriental approach, which is to work to incredibly fine tolerances but to
specify very thin cheese as the construction material. I love the apparent
non-obsolescence of the USA paradigm which implies that in a post apocalyptic
world we can all get by, fixing stuff with a hammer and baling wire, making
spares as needed with the help of the local blacksnith. It's just got a
better feeling that knowing you'll need a dedicated computer with constanly
updated firmware to make the most basic adjustments to your hedgetrimmer,
toaster, motorcycle, router and yes indeed, _washing machine_... It's the
sort of thing that drives us to working with wood, isn't it?
The rub comes when the tank-like build quality is not matched by _functional_
quality, either through crap design (Whirlpool washing machines, so it
seems), lousy tolerances in manufacturing (AMC Harley Davidson) or
anally-retentive tolerance specifications (M16 carbines ??)
When USA conservative engineering is combined with marketing honesty, you
guys turn out gear that rocks. It doesn't happen all the time, however, and
that needs a little consumer honesty to point out. Just 'cos something is
marked "Made in the USA" doesn't mean it's going to trump the competition,
regardless. Often it does, but there's no sense in getting all fierce and
patriotic to try and flog a dead horse - at any price.When it works, it
works. SnapOn tools, etc.. The process is not automatic, though. Badging a
thing "American" does not confer quality. Neither does "Made in Japan." It
can often be an indicator that something has a high probability of being
superior, but it's only a probability marker. The quality comes from
something else, but hey, it feels good to support the home team, and there's
nothing wrong with that - just let's not get confused about the issues.

120Vac so there's not enough juice to put a heater in, they run off
domestic hot water which of course is not always hot because the
dishwasher empties out the hot tank each time. We have the fabulously
expensive Maytag Neptune, 12 months of use and it stank like a septic
tank, as did the clothes. This is due to the fact it fills with luke
warm water to wash, no boil cycle here or even over 60C to kill the goop
living in the drum. Of course top loaders are king here because they
don't have that problem. The Neptune is a front loader, I really can't
stand 1950's top loader technology (do they have mangles still?).
Solution was to not close the door when not in use, bit inconvenient but
simple enough. Showers rock over here, or at least they did until the
enviroidiots put a flow regulator in them, they are usually mains
pressure hot tank fed, no chance of a piddling UK electric shower, the
8Kw heater would black out our local town.

There are many front loaders in the U.S, with built in water heaters now. I
own one made by Whirlpool for Sears. The Maytag Neptune problem had nothing
to do with water temperature. They included a light that lit up when you
left the door open so everyone closed the door. Try that on most machines
and it will start smelling from mildew. The fix was a free upgrade to a
ventilated door and mildew resistant tub. My parent's upgraded Neptune is
10 years old and smells great inside.

As has been pointed out, 120VAC has enough juice to heat water in a
machine to wash laundry or dishes.
If a child (or adult) contacts a live conductor, 240VAC will be a worse
problem than 120. American households can supply appliances with 240V
using conductors that are only 120VAC from ground.

A machine of similar design and identical, or better, performance, can

A Dyson doesn't lose suction because it doesn't have any to start with.
