This vacuum cleaner is very small and efficient. Noise wise, its just like any other vacuum I've used, and it works wonders on my hardwood floor, I wouldn't know about carpet!
I bought the pet version as my fiancé has long hair, and it gets everywhere, hoping that this could cope with it, and it can!
The push-around pole that comes with it is really long, but adjustable in 1-inch increments, and it coems with what I call a "normal" attachment for pushing round floors, the crevice tool, brush thingy, and the turbo tool, which is just like the spinning brushes you get on the bottom of an upright vacuum (but obviosuly you can maneouver it anywhere!)
The 6 year warantee is excellent, I believe they even pay for the shipping costs should you need to get it fixed. With so many things breaking a year after you buy them, this was the deal clincher for me. Don't forget to register for it though!
UPDATE: to those who are saying "it fills up too quickly" etc etc - yes it does, it's a small hoover. If you want to get the max out of your hoover (and want it to last a long time) actually READ the maintenance instructions that come with it and clean the filters regularly. I empty the chamber after every time i use it (hardly rocket science) and have had no loss of suction in 6 months now. For those complaining about the lack of a wattage rating, the whole system is pants, as that just tells you how much electricity the motor draws, and not the sucking power. you could get a 4000W hoover that was 10% efficient at sucking and it would beat a 100W that was 100% efficient (gross exaggeration).
