iRobot advertises that the Roomba j9+'s Clean Base holds up to 60 days of debris, but actual replacement frequency depends heavily on your household.

Realistic Replacement Schedules

| Home Type | Vacuuming Frequency | Bag Life | |-----------|--------------------| ---------| | Small home, no pets | Weekly | 3+ months | | Average home (~1,150 sq ft) | Weekly | 2-3 months | | 1-2 pets | Daily | 4-6 weeks | | Multiple shedding pets | Daily | 3-4 weeks |

Signs It's Time to Replace

• Red LED indicator on the Clean Base
• Robot repeatedly attempts to empty itself
• Bag feels firm and puffy when you check manually

Cost Breakdown

| Option | Price | Per Bag | |--------|-------|---------| | Official iRobot bags (3-pack) | ~$20-25 | ~$7-8 | | Third-party alternatives | Lower | Varies |

iRobot recommends authentic bags for optimal fit and allergen sealing, particularly for households with allergy concerns.

How to Replace

1. Open the Clean Base lid
2. Remove the full bag—it seals automatically
3. Insert a new bag until it clicks
4. Close the lid

The automatic sealing prevents dust from escaping during removal, which is especially valuable for allergy sufferers.
