Why do we scrub the heavy thing back and forth when it has fast revolving
brushes? Surely a single slow pass is just as effective.

Same as using a hover lawn mower and moving from side to side when just
forward does the same job.

I was wondering the exact same thing the other day brushing my teeth
with the electric.

People like doing things even if pointless. Like flapping Polaroid
photos while they develop.

Not really as the brushes agitate some of the grit etc out of the pile and
going over it forwards and backwards brings more out.

Why not apply the same logic to painting, just run the brush in one
direction only and see if that does the trick.

Not convinced its like, its more habit and not thinking about why they do
it.

I don't know I guess its habit. Many machines do not have fast revolving
brushes.
I often have thoughts about muck. where does it all come from?
Not all of it can be shed skin, so one must assume its come from outside
and maybe even outer space.

ISTR some research, years ago, that showed that around seven passes were
required to achieve the best cleaning.

To get good Polaroid you need a steady even temp that is why they invented
the cold clip that you put them into and put them under your armpit.

You scrub it back and forwards over the same bit of carpet?

Ask your wife about how to Hoover.

Corse it is.

Havent you got anything better to do ?

where does it all come from?

Various places.

Some of it comes off what we have.

Some of it comes in on our feet etc.

Some of its comes from the pets.

Some if it drifts in.

Not all of it can be shed skin,

Duh.

so one must assume its come from outside

Duh.

and maybe even outer space.

Nope. No aliens do either.

That number must be straight from someone's
arse given the different technologys used.

Quite. Known as the Electrolux when I was growing up. The verb is a bit
clumsy.
Morphed into Hoover when I married and remains so despite us using a
Meile and a Dyson.

If you tell a lie big enough and keep repeating it, people will
eventually come to believe it. The lie can be maintained only for such
time as the State can shield the people from the political, economic
and/or military consequences of the lie. It thus becomes vitally
important for the State to use all of its powers to repress dissent, for
the truth is the mortal enemy of the lie, and thus by extension, the
truth is the greatest enemy of the State.

That's the old "pull and peel" Polaroids. With the SX-70 type you had
five minutes to wait and flap.

I don't think a large proportion of household dust is from outer space,
but some micrometeorites do reach ground level, and are collected.

Here's a podcast about the subject:

Most of ours comes from our two border collies and their fur. It takes
several passes in different directions, to lift the hair.
