Its here: Not sure I'd want to pay over £400 for it though - its the price of that Lithium Polymer battery that makes it 4 times the price of a regular Henry!

Or even where power is available - they are saying that the problems of people suing companies for tripping over the cleaning lady's vacuum cleaner cable and all these new "elf and safety" laws is making things difficult for companies where the public can go back and forth, and possibly trip over a cable draped across a lobby or reception area etc.

They already use "backuums" or backpack vacs to vac aeroplanes and other places where power is not available. Its the health and safety aspect as I say and the fear of litigation leading to more battery vacs being used.

How about the Miele S4 Hybrid? they were around the £500 mark when launched - again you are paying through the nose for the batteries, and these only have a limited life of about 5 years.

So you'd be pretty limited to how much you could use it, depending on how many charged battery packs you had - bearing in mind, each battery pack only gives 30 mins run time before it has to be recharged, so if you had a lot of area to cover, then you'd either need to learn to be a very fast vacuumer or pay out for several batteries and chargers. Mega bucks!

But, as Benny says, these vacs are specialist machines for commercial use, and companies have considerably more money to play with than we do (Although many of them don't like spending it).

I have seen one being used on a Royal Caribbean cruise, Oasis of the Seas, they used it after the grand parade after they shot confetti all over the main concourse. The vacuums were almost silent, but the suction looked a little weak, for using them how they were using them they were adequate, they had no nozzle on the end of the want, they just used the want to suck up the confetti. All of the vacuums that Royal Caribbean uses are Numatics.
