The iRobot Roomba Plus 505 Combo extends the Plus series by combining vacuuming and mopping capability with a self-emptying dock, handling floors in a single pass while automating debris disposal at the end of each session. The dock draws collected dust and fine particles into a sealed replaceable bag, maintaining the robot’s suction performance and keeping the living space free of re-contamination during the emptying process. Regular bag replacement is the straightforward upkeep step that keeps the Plus 505 Combo operating on its daily schedule.
These 15 spare bags are shaped to the Plus 505 Combo dock collar, each forming a complete seal through the pressurised emptying sequence. Fifteen bags covers months of regular daily vacuum and mop sessions before the next reorder. Each bag in this pack is a Plus.Parts® replacement checked for collar fit with the Plus 505 Combo dock before every batch ships.
Seam construction is consistent across all 15 bags, handling repeated suction loads through the dock’s emptying cycles without failure. Each bag confirms the fit firmly on installation. Our team is available for fit and dispatch questions, with personal replies on business days.
