No point getting Scooba only. Should get combo. From my experience, must use Roomba to vaccum first then
use Scooba to do the mopping.

If use Scooba without using Roomba , the Scooba will spoil easily as the pump will breakdown easily becoz
a lot of dirt will go into the pump even though Scooba has a filter.

So far based on my experience of using roomba 560 , 3000mAh APS yellow battery since August 2010. I use it everyday to clean 2000 Sq Feet house. The battery is still ok, like brand new.

For Roomba to last , u need to take care of the Clean Head Module , so that dust doesn't go into the gear box. If u don't have pets in your house.
u need to clean the gear box perhaps once every year.


If u have pets u have to clean it at least 3 times in 1 year.

Also u need to clean hairs from the yellow bearings of the brush and also the side brush.

Regards.
