U can find the info by searching around. Still if you are not familiar with electrical stuff and soldering I recommend getting a good 100W transformer instead. U ordering from USA? This package is good if you need both types and the features. Scooba 380 - highest end scoob Roomba 400 - lowest end roomba (feature wise)

just for guidance, mod the charger for the 5xx series same as the previous series in terms of replacing the components?

so modding the power supply is still the best thing to do for the life of the battery... I think perhaps I need to take up some basic electronics lessons. Do u happen to know if the shops in SLT selling the parts will do the mod for a fee?

but someone warn me that transformer will eventually kill the battery after some time. I tried to read up on this but there's no specific info on why this is so. I thought transformer (although Newstar one I have says convertor) just steps down the voltage. Maybe u have some electrical knowledge can advise if using a transformer got any detrimental effect on battery/charging. My roomba came with the old brush. I have not run it fully while at home to watch it so can't confirm the rattling, I suspect that it rattles when running on the parquet flooring but can't confirm until I see it for some time. I'll write to iRobot to see if they will send the new brush, even if they do will need to incur additional shipping costs.

My roomba 535 arrived last week and is now happily going about its work. Agree with bro koh, the lighthouse thing is quite useful, cleans living room first before moving to the bedrooms. Also like the soft touch bumpers. However my roomba is already scratched in the course of duty. I'm using a Newstar 100W transformer as I have no knowledge on soldering etc, will this be bad in anyway after a few months as compared to modding the given power supply?

Good tips. Can share on the modding of 5xx roomba charger and how it is done?

see the videos on irobot.com or even better irobotkorea.co.kr. If you are still doing the MO, interesting deal at www.tryscooba.com, Scooba 380 + free Roomba 400. Buy now leads u to the irobot website.

let me know if you found the way to tweak the power supply. I'll be keen to learn from u as I hv zero knowledge in such things.

btw I wasn't aware the 2nd batch is available, does it fix all the known issues like rattling noise? How abt trying to order the 535 from HSN, it's a good mix of features.

Any details? Can still use the Newstar or Super 100W transformer if get the new model?
