How about banning the 5 worst performing vacuum cleaners?]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12472&Focus=207640#Comment_207640 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12472&Focus=207640#Comment_207640 Sun, 24 Aug 2014 22:39:56 +0100 rhamdu http://www.telegraph.co.uk/news/worldnews/europe/eu/7996383/Europe-to-cut-power-of-vacuum-cleaners-to-save-energy.html

According to that story, Dyson vacuum cleaners are among the most efficient, and average 1.2kW.

The Numatic Henry has a motor power of only 580W, and that machine is good enough for many professional cleaners.

I suspect that the power consumption of domestic vacuum cleaners has crept up to 2kW and beyond, for two reasons: (1) noise reduction and (2) trying to force the air through small bags with inadequate surface area. Why are the bags so small? Well, then you buy new ones more often But in fairness the manufacturers may be shrinking the bags to produce compact, manoeuvreable and lightweight machines.

I use a Numatic for building work. Our home machine is a Miele, smaller, quieter and using nearly four times the power. The Numatic bags are large, and heavy when full, but the motor doesn't have to work very hard to suck air through them. The bags are fairly expensive. But unless you are using the machine instead of a shovel to pick up heaps of rubble, they take quite a long time to fill up.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12472&Focus=207733#Comment_207733 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12472&Focus=207733#Comment_207733 Tue, 26 Aug 2014 08:34:18 +0100 fostertom http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12472&Focus=207740#Comment_207740 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12472&Focus=207740#Comment_207740 Tue, 26 Aug 2014 09:10:38 +0100 Beau Posted By: fostertomWe had a white Panasonic and a broken black Panasonic.

My general view is that new vacuum designs will become more efficient quite quickly as a result of a move to largely battery powered cleaners. Cleaners like the recently released Bosch with an hours battery life are leading the way, and although I haven't tried one I suspect they are a lot more convenient and faster than continually plugging and unplugging a lead?]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12472&Focus=207830#Comment_207830 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12472&Focus=207830#Comment_207830 Tue, 26 Aug 2014 18:30:00 +0100 mike7

Excellent point. I think the cordless transition is very close. From 'pah, it's just a Dust Bug' to 'why on earth did your electrician put a socket on the stairs?']]>
