The iRobot Roomba i3+ is iRobot’s mid-tier i-series robot bundled with the Clean Base auto-empty dock. The i3 platform adds a smarter navigation pattern than the entry-level i1, covering more floor area per session while still fitting the same Clean Base ecosystem. After each cleaning run, the Clean Base draws the robot’s bin contents into a sealed internal bag housed in the base unit, accumulating through up to thirty complete emptying cycles before the indicator calls for a bag change. On a busy household schedule running the robot daily, that typically means a bag change every four to six weeks.
These three spare bags are Plus.Parts® replacements built to the same dimensions as the bags that come with the i3+. Each one loads into the Clean Base dock’s loading port and locks via the standard tab closure, ready to accept incoming debris the moment it is seated. Ordering three at once keeps a supply available so the dock can continue operating immediately after the current bag reaches capacity.
Bag material is selected to maintain its sealing performance from first use through to the final disposal step. The closure designed to retain debris when the bag is removed at maximum fill works on the same mechanical principle as when the bag was first installed, with no degradation in seal reliability as the bag fills.

The quick version
- Three Spare Bags – A pack of three gives several months of Clean Base dock supply, preventing a service gap when the current bag fills on schedule.
- Built to Match – Tab and port dimensions match the iRobot Clean Base dock supplied with the Roomba i3+, fitting the same way as the original bags.
- Personal Support – The VacuumReviews.eu team is available for compatibility questions specific to your i3+ dock model.
