KTNAid Replacement Kit for iRobot Roomba 505X/505/507/405 Combo — 25-Piece Set with Brushes, Filters & Mop Pads

KTNAid's 25-piece replacement kit refreshes iRobot Roomba 505X/Plus 405/505/507 Combo vacuums with new brushes, filters, dust bags and mop pads for consistent cleaning performance.

When a Roomba's consumables wear out, suction, edge cleaning and mopping quality drop. This comprehensive set supplies the main components you replace most often, letting you restore multi-surface pick-up, edge reach and wet-dusting without buying individual parts. Everything in the kit is designed to fit the listed Combo/Plus models—double-check your Roomba model before ordering to ensure compatibility.

Which Roomba models will this 25-piece kit work with?

This replacement assortment is built for iRobot Combo and Plus machines in the 405, 505, 505X and 507 ranges. Fitment is model-specific; confirm the model number printed on your robot's base or in its app to avoid mismatches.

• Compatible: Roomba 505X Combo, Plus 405 Combo, Plus 505 Combo, Plus 507 Combo
• Included parts sized to match original manufacturer dimensions
• Not universal — check model label before purchasing

What parts are included and how do they help performance?

The kit contains the common wear items that directly affect cleaning effectiveness: main brushes and side brushes for debris pickup, HEPA-style filters for dust capture, microfiber mop pads for wet cleaning, dust bags for debris containment and a tool for maintenance.

• 2 rubber main brushes to lift hair and dust from floors and carpets
• 6 side brushes with nylon bristles for corners and edges
• 4 washable filters that trap fine particles and protect motors
• 6 dust bags with sealing strips to minimize leakage when removed
• 6 microfiber mop pads for absorbency and streak-free mopping
• 1 cleaning tool to remove trapped hair and debris from brushes

How long will these replacement parts last and how often should I swap them?

Longevity depends on floor types, pet hair volume and run frequency. As a practical guideline, replace high-wear parts every 3–6 months; filters and mop pads may need more frequent attention if you run the robot daily or have pets.

• Replace brushes and side brushes every 3–6 months with regular use
• Washable filters: rinse and air-dry, replace every 3–6 months
• Mop pads: launder after heavy use, replace when stains or wear persist
• Dust bags: swap when full or when suction drops

Are these parts reliable and easy to install?

KTNAid parts are manufactured from durable materials and engineered to match the originals’ fit and function, making installation straightforward for most users. The included cleaning tool speeds maintenance and helps keep brushes free of hair that can reduce efficiency.

• Main brushes: flexible rubber design resists hair wrap and flexes to floor contours
• Nylon side brushes: angled bristles reach edges without scratching floors
• Dust bags: reinforced seals and buckles reduce dust escape during removal
• Microfiber pads: washable, high-absorbency fabric for streak-free mops

Who is this for: This kit is ideal for owners of compatible iRobot Combo/Plus models who prefer proactive maintenance or want a one-time purchase to cover several replacement cycles. It suits households with pets, high-traffic areas, or anyone aiming to keep their Roomba running near factory-level performance without sourcing parts separately. If you’re unsure of your model, check the robot’s label or app first—this ensures you get the correct fit and the full benefit of the replacement set.
