**Brand:** iRobot

## Realistic Replacement Schedules

| Home Type | Vacuuming Frequency | Bag Life |

| Average home (~1,150 sq ft) | Weekly | 2-3 months |

## Signs It's Time to Replace

## Cost Breakdown

| Option | Price | Per Bag |
|--------|-------|---------|

| 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.
