- Turn the robot vacuum cleaner upside down.
- Locate the main brush cover, usually secured by latches or screws. Open or remove the cover.

2. Side Brush Installation
Side brushes sweep debris from edges and corners into the vacuum's path. Replace them if bristles are bent or missing.
- Turn the robot vacuum cleaner upside down.
- Locate the side brush(es). They are typically held in place by a single screw.
- Unscrew and remove the old side brush.
- Place the new side brush into position and secure it with the screw. Ensure it is firmly attached.

3. HEPA Filter Installation
The HEPA filter captures fine dust and allergens. For Conga 4090 and 5090 models, this filter is specifically for the water tank.
- Open the dustbin or water tank compartment of your robot vacuum.
- Remove the old HEPA filter.
- Insert the new HEPA filter into the designated slot. Ensure it fits snugly to prevent air leakage.
- Close the dustbin or water tank compartment.
4. Mop Rag Installation
The mop rag is used for wet cleaning functions. Ensure it is clean before each use.
- Locate the mop attachment or water tank on your robot vacuum.
- Remove the used or old mop rag, typically by detaching it from a hook-and-loop fastener or sliding it out of a groove.
- Attach the new mop rag, ensuring it is flat and covers the entire mopping area.

Operating Considerations
Once replacement parts are installed, your robot vacuum is ready for operation. No special operating procedures are required beyond the standard use of your Cecotec Conga model. Ensure all parts are correctly installed before starting a cleaning cycle.
Maintenance
Regular cleaning and timely replacement of parts are essential for maintaining your robot vacuum's cleaning efficiency and longevity.
- Main Brush: Clean the main brush weekly by removing tangled hair and debris. Replace every 6-12 months, or sooner if bristles are visibly worn or damaged.
- Side Brushes: Clean side brushes bi-weekly. Replace every 3-6 months, or if bristles are bent, broken, or missing.
- HEPA Filter: Tap out dust from the filter weekly. Do not wash HEPA filters with water unless specified by your vacuum's manual. Replace every 2-3 months to maintain filtration performance.
- Mop Rag: Wash the mop rag after each use. Replace every 1-3 months, or when it shows signs of wear and reduced absorbency.
Troubleshooting
If you encounter issues after replacing parts, consider the following:
- Reduced Suction: Check if the HEPA filter is clogged or incorrectly installed. Ensure the main brush is free of obstructions.
- Ineffective Sweeping: Verify that side brushes are clean, not tangled, and correctly installed. Replace if bristles are severely damaged.
- Poor Mopping: Ensure the mop rag is clean and properly attached. Check if the water tank (if applicable) is filled and dispensing water correctly.
- Unusual Noises: Inspect all brushes for tangled hair or foreign objects. Ensure all parts are securely installed.
