KTNAid 25-Piece Replacement Kit for iRobot Roomba Combo 405/505/507 — brushes, filters & mop pads

KTNAid's 25-piece replacement kit supplies all routine wear parts for Roomba 405/505/507 Combo series robot vacuums so your machine keeps cleaning reliably.

Keep your Roomba-style Combo cleaner running at peak performance with a complete set of replaceable consumables: main brushes, side brushes, filters, dust bags, and microfiber mop pads plus a cleaning tool. These aftermarket parts are made to match the fit and function of the listed Combo-series models; they are not original manufacturer parts. Replacing worn components on a regular schedule helps preserve suction, sweep-and-mop effectiveness, and reduces cleaning time.

How will this kit affect daily vacuum and mop performance?

Fresh brushes and a clean filter restore pickup efficiency and reduce hair tangles, while new mop pads recover absorbency for better streak-free mopping. Using the full kit together returns multiple subsystems to near-new condition.

• 2 rubber main brushes for debris lift and hair management
• 6 side brushes to improve edge and corner access
• 6 microfiber mop pads for improved moisture pickup
• 4 replacement filters to reduce dust recirculation

Which models are compatible and how should I confirm fit?

This accessory pack is designed for Roomba 505X Combo, Plus 405 Combo, Plus 505 Combo, and Plus 507 Combo machines. Verify your robot’s model number on the underside or in the app before ordering to ensure parts align with your unit.

• Check the model printed on the robot or in device settings
• Compare main brush and dust bag shapes before installing
• Contact support with a photo if you’re unsure about compatibility

How often should I replace these parts and maintain the robot?

Replacement frequency depends on usage and home conditions. As a guideline, inspect and swap parts every 3–6 months: brushes and filters more often if you have pets or heavy dirt loads.

• Replace filters and brushes every 3–6 months under moderate use
• Swap dust bags when capacity is reached or airflow drops
• Wash mop pads after each wet clean and replace when worn

What’s included in the package and what extras come with it?

The kit bundles the most commonly replaced consumables so you can refresh your robot without multiple purchases. A small cleaning tool is included to help remove hair and debris from brushes and filters during routine upkeep.

• 2 main rubber brushes designed for debris pickup
• 6 disposable dust bags with sealed buckles
• 6 washable microfiber mop pads and 6 side brushes
• 4 filters and 1 compact cleaning tool for maintenance

Who this is for: This kit suits owners of the compatible Roomba Combo series who want a cost-effective, single-purchase way to replace all routine wear parts. It’s ideal for households with pets, frequent cleaning needs, or anyone who prefers to perform timely maintenance themselves instead of buying individual components. If you need help confirming compatibility or have questions about installation, KTNAid support is available to assist.
