As Shaun says I do have the Airflex but not the Storm (yet!). I will be getting one soon though.
You are welcome to come over to Edinburgh and have a go but as i said its not the Storm model.
Never delt with Solutions but I have delt with Cleansmart and i can say first hand they are a great company to do business with!
Having been cleaning carpets and upholstery for over 15 years (12 self employed) the Airflex is the best machine i have used by far and thats with trying most portable machines on the market.
Very well built and thought out machine. Replacing (wearable) parts is extremely easy and quick. You can have the machine open in two parts in less than a minute and with no tools needed!
And there's a nifty break at the front wheel! so you can rest the machine on an incline without worry.

Edit: comes with an hours counter too! This is very useful as you know exactly how many hours your pump and vacs have done. There are some on here that can go for years without changing parts... empty diary springs to mind
