Hi, Salam

I can suggest you, Roomba can have for fully automatic vacuum & self-charging.

Scooba just used water and mopping for you & without lesses vacuum up hair & dust, if you all the time using Scooba will be shorter the life, cause you without Roomba to helping to pikes up all those hairs & debris.

Roomba can vacuum up 80-90% clean, but just only cannot used water to mopping on floor.

Scooba is just the mopping only. If more dust or hairs will be easily spoil the suction motor. & fully manual release tank & discharge water and refill new water, even charging also using manual to charged.
There is very basic even you are using regular mop, but you still need to change water.

Thanks
