Question 1

How often do I need to clean the bin, filter and brushes on the Roomba Combo j9+ if I have a baby or pets?

Accepted Answer

Empty the bin after every job and rinse the bin as needed; clean the filter once a week (or twice weekly if you have a pet); remove hair and debris from the multi‑surface brush and side brush about once a month (or twice a month with pets) and check the full‑bin sensor every two weeks as recommended by iRobot.[1][3][8][4]

Question 2

What maintenance steps prevent clogs or a stuck refill tank float when using the mopping function?

Accepted Answer

Rinse and refresh the refill tank water regularly, and if the tank float becomes stuck fill the tank with warm water and shake to free the float; also follow the tank cleaning steps in the app or manual to avoid mopping errors.[1][5]

Question 3

Will the Roomba Combo j9+ reliably avoid baby toys, socks and pet bowls with its mapping/vision system?

Accepted Answer

The Combo j9+ uses PrecisionVision Navigation to detect and avoid common obstacles in real time, which reduces collisions with toys, socks and bowls, but small low‑profile items can still be missed so tidying larger stray items is recommended for best results.[1][9]

Question 4

Can I teach the Roomba j9+ where to clean and where to avoid (for example a baby play area or pet feeding station)?

Accepted Answer

Yes — the app supports saved maps and virtual no‑go zones (and the robot learns rooms for targeted cleaning), so you can block off baby play areas or pet feeding spots and schedule room‑specific cleans.[9][1]

Question 5

How well does the j9+ pick up pet hair from carpets and hard floors, and any tips for heavy shedding seasons?

Accepted Answer

The Combo j9+ vacuums while mopping and is effective on pet hair, but for heavy shedding clean the filters and brushes more often (filters weekly, brushes monthly or twice monthly with pets) and regularly remove hair wrapped around the brushroll to maintain suction and performance.[3][4][1]

Question 6

Is the Roomba Combo j9+ noisy around sleeping babies or napping toddlers?

Accepted Answer

While the j9+ is quieter than many full‑size vacuums, it still produces noticeable noise during cleaning and when the Clean Base is emptying; use app scheduling with Do Not Disturb or run cleans when your child is awake to avoid interruptions.[2][1]

Question 7

What common obstacles cause the j9+ to get stuck and how can I prevent it?

Accepted Answer

Common snags include loose cords, thin rugs with tassels, small toys, and piles of laundry; secure or remove cords, pick up small items, tuck rug edges, and use virtual boundaries in the app to keep the robot out of areas with many potential entanglements.[2][1][9]
