Firstly, congratulations, Turbo500, on your radio 'appearance' (do you actually 'appear' on the radio???) and for helping to debunk decades of poor and lazy advertising. Nice comment about 'Joe Public' expecting a machine to work 'out of the box' and not having a collection of alternative accessories to try (Reply#31)
Desert Tortoise (and others) (Reply#42, et al) makes good points about comparative testing of cleaners. It would be interesting if some of our members could organise some sort of objective tests of 'pick-up' capability on various surfaces, but (IMHO) there are probably too many variables to make this practicable.
Suction Selector mentions having £1,000,000 in front of him. As a matter of (possible) interest or amusement, I actually HAVE had £1,000,000 in front of me, then later under me. It makes quite a lumpy seat!! ;-) . You would be surprised at just how bulky that amount of money is!! Needless to say, it wasn't MY money... :'(
Gr8DaneDad (Reply#45) discusses U.K. canister machines with power nozzles. I've never seen one at all in the U.K. Some early 'Henry' cleaners had a socket for the power connection, but I personally have never seen a floorhead which would use it. We do have a few floorheads with airflow powered brushes (usually described as 'pet' floorheads), but anything else is uncommon indeed.
I (in my limited experience), prefer a canister type cleaner for reasons of lightness of weight of the 'moving part' (no power nozzle, see paragraph above), and superior manouverability.
Thoth (Reply#51) doubts that there will be any great benefit to the consumer in terms of costs and/or reliability. I tend to agree. any new designs will still be cheaply made 'plastivacs' designed to fail after a short working life. lightness of weight (use of less materials i.e. thinner, weaker parts) will still be a major selling point.
Personally, I'm not concerned whether the new, lower wattage vacuum cleaners perform as well as the current crop of high powered beasts or not. Most people these days could use a bit more exercise (me included), so if it takes a few extra passes to clean the floor, what of it??
All best
