a) some of the forummers mentioned Scooba 380 require more "attention", may I know what are the required attention?
Change water, clean tank, filter etc after EACH usage (recommended). Water Tank esp as it will stink overnight
b) I read some reviews complaining that if it is placed in a small room with full tank, it will not stop until consuming the tank. is it true?
ya. because if its only within the small room, it will just clean n clean until no clean water or no battery
b) does it have a scheduler? how does a scheduler work?
dont have. scheduler i think its like u set when to let it run.
c) can Scooba 380 finish a HDB 5 floor flat floor space in a single charge?
i use 1 single charge to clean 2 areas which is 1 third of a 5room. I can use 1 cleaning cycle to clean my tiny kitchen. i think thats why i find it very clean. i dont have time to move it ard. so i prefer to do it room by room and cycle by cycle.
d) do I need to do maintenance after 30-45min of run?
u need to at least change water. if filter etc area is dirty, its best to wash the dirts off too
e) any idea how come a Roomba is "smarter" even though they came from irobot?
Roomba goes to a base to charge itself if it has home base. SCooba cannot. DIY charging
f) what are the accessories I should get?
Battery. Other than that, maybe the soft bumper to protect yr furniture. the rest still okay. maybbe brushes but i think thats abt at least 8mths issue from now
wheels might get wear out sooner too due to heavier usage. maybbe 6-8mths can change
