Most of the large supermarket outlets are selling domestic compact
vacuum cleaners (1300/1500W) for under £30.

I have one and it works well. It is built to a price but it is 'fit for
purpose'. Judging by the amount of heat my cleaner generates much of
the
1300W may be due to motor inefficiency.

The disposable collection bag is relatively small (6x6x4 inches) to
fit the small size of the machine so consider the cost of the bags if
you are using it a lot for major cleaning activities.

As for getting into small nooks and crannies the supplied tools are
about the same size as supplied with any larger cleaner. However, it is
easy to hold the machine in one hand while sucking up the rubbish using
just the end tool on the flexible tube.

Thanks, Alan!

First realistic answer today (please note to all Henry fans it does NOT

meet

my specification however much you love it).

Then your specification is most obviously wrong!!!

;-)

You'll eventually be lured by the hypnotic gaze of a Henry...

Given the improvement in battery performance in the last 10 years, it
must
surely be possible to buy something approximating to a dust-buster on
steroids. I haven't seen one though.



A SUB C cell will deliver about 30 watts for 6 minutes, top technology.

You will need therefore around 30 of them to get a kilowatt for 6 minutes.

The cost will be around £100 for these rechargeables, to give you 6
minutes of mains performance vaccum cleaning.

The unit will weigh 15lb for the batteries alone.


Now would you care to rethink that? :-)




Well, won't disagree with the calculation, but just 2 points.

1) Couple of hundred W would do the dustbuster on steroids, surely?
2) Batteries have sufficient power to drive circular saws, would have
thought that it was possible to create a reasonably powerful vacuum with
such a motor/battery combination. Granted, they're expensive though.

Perhaps I'm thinking abut the wrong solution though. A dustpan and brush
combination are now coming to mind... :-)

cheers
