WiseOne, in my 1st sentence here:

When I wrote "I applaud ur courage to buy a newly launched product", it's by no means sarcasm.
I'm just amazed by all the regular forummers here who bought various brand robots overseas, effectively without any local tech support (Yes, Bakasa u amaze me no end!).
Many regulars here have used iRobot way before me, I only started using Roomba 400 series in Mar 2008.
I bought V-bot in Oct 2007, lasted me 5 mths & battery died. I even had to mod the front wheel as described here:

Another crazy mod I did for V-bot was actually same concept as Mint Plus. A bag of water, an aquarium air pump adjustable valve, drips water via air pump tube onto a modded Magiclean mop head with melamine sponge & microfibre paper, V-bot will drag this constantly moist attachment.
I also bought Advante Stingray steam mop, used 5 times didn't wanna use liao. Same goes for Step & Spin mop, forced myself to use maybe 5 times for small area, never once used it to mop anything larger than my bedroom.
Hence, I can GUARANTEE one thing, no one likes manual cleaning, which is why I've met so many customers who got Delphin or Rainbow, but are white elephants.
As I wrote "The only concern for me is always the ability to service" (in last para), it's a genuine concern since most new products will go thru many revisions to "smooth out the kinks". Just like Windows XP, Windows Vista, iPhone 4S, Nokia Symbian^3 OS.
When I first used robotic cleaners, I just wanted something to clean my floor other than myself. When the V-bot battery died, I spend a lot of effort to revive battery. Read a lot of battery forums, tried freezing the battery & finally bought my 1st computerised charger.
Same goes for Roomba 400 series, when it first exhibited "Circle Dance". Had to search forums for an answer.
So I've been thru the routine of "I want to buy it so badly -> Oh crap! Down again? -> I want to rectify it so badly"
