Why not dyson??? It is available in europe too.. and is probably the best one around. Sure it does not have the wet spillage function, but for a quick clean it is great. Also great for cleaning the car. It is more expensive than the rest but you really do pay for what you get. The other cheaper ones just don't work well and don't last that long so really it is false economy in my opinion.
We have the Dirt Devil ‘Kone’ designed by Karim Rashid. Not only that it looks good sitting at one corner of your room, power and suction capabilities are awesome, its easy to clean and extremely durable. We have it from last 4 years and it still works like a new one.
Have you tried internet shopping? My cousin is in switzerland and buys a lot from the internet. A price comparison site can even tell you where you can buy handheld Dyson the cheapest. I got mine from the website Amazon. A fully charged vaccum gives you around 7 minutes, which is more than enough to pick up kids' mess.
