Thinking of selling my Roomba 550 as my house not suitable for it anymore...
Battery is weak....most sligtly needs replacement.
Anybody keen?
BTW, I bought 1 transformer that can handle up to 1650W, it is slightly bigger than the 80W only. When I use the high power mode, it has loud buzzing sound, is that normal? I need one that can handle my Raycop UV vacuum thy draws 350w...shall I return it and ask for refund and get a better brand one?
The brand is Vanson, model number is TS-1650... When I plug my vacuum, it is very loose leh...
