Hi Jubooo,

Mine is the black Nicd, how to revive the battery life?

It involves shorting it to fully discharge it first. There would be spark, u also need a voltmeter & probably a 12V car battery. If you have all these, I can advise you further.

Shorting battery is extremely dangerous, even a 1.5v AA when shorted can give u a wire with melted rubber coating within 10 secs.

Full discharge of cells can be achieved by connecting to a load, eg. motor with propeller or something. But a 14.4v pack connected to a tamiya motor will probably fry it within 1 min. U can try draining the batt using 12v car vacuum, but if u use crocodile clips, the wires better be thick.

Even then, unmonitored discharging of battery pack will risk cell polarity reversal which permanently damages the weak cell, from weak -> DEAD!!!

If u're thinking of zapping using 12v 100 Amps car battery, it has to be swift, else cells may pop their pressure vent when the electrolytes inside boils.
Zapping has short-term effect anyway, since the cathode-anode membrane was already ruptured due to dendrite crystal spikes. Such "revived" cells will self-discharge double quick time, and u'll end up with an unbalanced pack once again.

You are extremely right on this issue. The shorting is only a momentum striking on the cells and that is why there would be spark.

Ya, I am also interested to see how much are they pricing the navibot and how does it measure up with the roombas. :)

It should be price closed to $1k. I like the room mapping features but I don't really know if it really can clean properly with just a single pass on that spot. You have seen how roomba cleans and it sometimes just miss out some debris or the exhaust will blow it aside but however subsequent revisit to the same spot takes care of it.

In my opinion, roomba is still pretty cool in terms of effectiveness. Just look at the debris bin and filter very time it finished it's job. I'm pretty impressed by this little thing.

Maybe I shdn't be saying this too early, but I really like the roomba being very hardy. Apart fr a batt and some brushes replacement, my 535 is working ok for about 2.5 yrs. Anyone want to buy it from me, so I can upgrade? Hahaha ..

Hi all,

Can I check how long long does your roomba 560 cleans the house before it goes back to dock and charge?

Thanks

That will depends on your floor area and how much furniture you have. On an average is about 1-1.5 hrs.
