The iRobot Roomba w155040 is a current-generation Roomba paired with a self-emptying dock that automates the debris disposal step between cleaning sessions. After each run, the dock seals collected dust and particles into a replaceable bag, keeping the robot’s bin clear and containing fine debris until the bag is due for replacement. The dock’s bag is the single consumable that enables the w155040’s hands-free cleaning routine, and maintaining a supply on hand is the straightforward upkeep step that sustains it.
This replacement supply includes 15 bags shaped to the w155040 dock collar, each seating precisely and sealing completely through every pressurised emptying cycle. Fifteen bags provides months of daily-use supply before a reorder is needed. Each bag in this supply is a Plus.Parts® replacement verified for fit with the w155040 dock before every batch leaves for dispatch.
Seam quality is consistent throughout the supply, with each bag holding through repeated auto-empty loads without failure. The collar engages firmly and gives a clear installation confirmation. Our team handles fit and delivery questions personally, with replies available on business days.
