The iRobot RCA-Y1 is the robot platform at the centre of iRobot’s Roomba Combo j and c lineup, a vacuum-and-mop combination that cleans all floor types and deploys a retractable mop pad onto hard floors in a single run. The architecture uses a high-efficiency filter in the exhaust path to capture fine particles before the air circulates back into the room. These filters are not washable: they are designed to be replaced on a schedule, and iRobot recommends renewal every one to two months depending on use. In practice, a home with pets or frequent runs will reach that interval faster: fine hair, dander, and dust particles fill the filter media from the inside out, and once the media is saturated, pickup efficiency at the brush falls even if the motor runs normally. A fresh filter restores the full suction gradient and keeps the RCA-Y1 delivering what the Combo platform was designed to do.
This set contains four Plus.Parts® high-efficiency replacement filters designed as direct-fit alternatives for the iRobot RCA-Y1 filter housing. Each filter matches the original clip positions and seating geometry for tool-free installation. Four filters in one order sets up a maintenance schedule that runs for four full intervals without a repeat visit to the cart.
The filter media meets the filtration-efficiency specification of the original component, with consistent fine-particle capture across the full service life of each individual filter. Questions about compatibility or your order are handled personally by the team.
