Thanks for the response vic7767. I can't seem to find the "Built in Test mode" procedure for the Scooba 450. Where would I find it?

I have a brand new Scooba 450 that runs a full 40 minute cycle but doesn't lay down any water. After the cycle, the clean tank is full and the empty tank empty. I have updated to the latest firmware as well as checked the three connector pins. Everything looks in order. Is there anything else I can ...

Hi All

Does anyone know if the power supply for the Looj is 110V-240V or is it just 110V for USA? Any pictures would be much appreciated.

Thanks.

Hi mfortuna Unfortunately it is quite different to the power supply found in the Scooba and Roomba. It is an external brick but quite large. I can't find the specs for the power supply so am not sure what it can be replaced with. If I can find those details then I may be able to find a step down tra...

Hi Kazy

Thanks for the review of the mint. Do you know if this unit has a power supply that supports 220v/240v? Maybe you can post a picture of the power supply with details?

Many thanks.

Hi All

I have managed to get hold of a Verro 100 pool cleaner but have noticed it is only for use on 110v. Is there a way to modify the power supply to work on 240v Australian Power? Any ideas would be much appreciated.

Many thanks,

Hi Guys. I just noticed that the component 1200P60 is the same one as used on the Roomba 500. The charging circuitry looks very similar. There is a picture of the 500 series PSU at:

Thanks Gordon. I won't try and do any modding on those power supplies until someone has investigated this fully. I am a qualified Electrical Engineer however the last time I worked on circuit boards was way back in university which means I have forgotton almost everything :) I noticed that the model...

Hi Gordon. Thanks for the prompt response. D1 thru D4 are still 1N4007. The TOP246YN has been changed to another switcher which is the 1200P60. When you say use one 47u cap do you mean a 47uf 400v cap? I do you some more unmodified power supplies which I can try. I was just a bit worried about blowi...

I have modded quite a few Roomba and Scooba power supplies without any issues. I have noticed that iRobot have now changed the pcb for the Scooba Power Supply. In the old power supplies I used to change the 100uf 200v capacitor to a 400v 100uf. They are now using 2 * 200v 47uf capacitors in parralel...
