The manufacturer was on Radio 2 yesterday tea time talking about this.
It's rechargable, so cordless. A full charge lasts 40 minutes.
It is very energy efficient, so will pay for itself in elecricity used very soon (depending on how often you vacuum, obs!).
The cleaner sucks directly into a 'baler' that compacts the dirt into a bale that can go directly into the bin, no dust.
The slot for the dirt to go up is the size of a letter box, rather than the dirt being sucked into a small tube, making it much more efficient.
He said that it would do an average sized family home in 20 minutes, so a full charge could do the house twice.
He claimed that it is much better than even the strongest vacuums at sucking ground in dirt out of carpets.
I have a big house, with lots of cream carpets that always look grubby. My Henry is great, but hard work, and it gives me a bad back to use it too much. I like CLEAN carpets. Is the AirRam worth the £240? will it give me the joy and happiness I seek?
