4. Component Overview
4.1 Main Brush

Figure 4.1: Main Brush features.
The main brush features a V-shaped design, optimized for effectively gathering dust and debris from various floor types, including hardwood, carpet, and tile. Constructed from high-quality nylon and rubber, it ensures efficient cleaning with reduced noise.
4.2 Side Brushes
Side brushes are designed to reach into corners and along walls, sweeping debris towards the main brush for thorough cleaning. They are made from durable materials to withstand regular use.
4.3 Filters

Figure 4.2: Efficient Filtration System.

Figure 4.3: Replacement Filters.
The high-efficiency particulate arrestance (HEPA) filters are capable of capturing 99.97% of particles as small as 0.3 microns. This prevents dust and allergens from being released back into the air, contributing to a cleaner home environment. Each filter includes a sponge for enhanced filtration.
4.4 Mop Cloths
The mop cloths are made from ultra-fine fibers, designed for effective wet cleaning and polishing of hard floors. They attach securely to the vacuum's mopping module.
4.5 Cleaning Tool
A specialized cleaning tool is included to assist in removing tangled hair and debris from the main brush and side brushes, facilitating easier maintenance.

6.5 Replacement Frequency
To maintain optimal cleaning performance, it is recommended to replace the accessories every 6 months, or more frequently depending on usage and environmental factors (e.g., pet hair, high dust levels).
- Main Brush: Every 6-12 months.
- Side Brushes: Every 3-6 months.
- Filters: Every 3-6 months.
- Mop Cloths: Every 1-3 months, or as needed based on wear.
7. Troubleshooting Common Issues
If your robot vacuum cleaner's performance declines after replacing parts, consider the following:
- Reduced Suction: Ensure filters are clean and correctly installed. A clogged filter significantly reduces suction power.
- Poor Edge Cleaning: Check if side brushes are tangled with hair or debris, or if they are worn out and need replacement. Ensure they are securely screwed in.
- Main Brush Not Rotating: Verify that the main brush is free of obstructions and properly seated in its compartment. Check for tangled hair on the brush ends.
- Water Leaks from Mop Module: Ensure the mop cloth is correctly attached and not obstructing any water outlets.
- Unusual Noises: Inspect all brushes for foreign objects or excessive wear. Ensure all parts are installed correctly and securely.
If issues persist, refer to your iLife robot vacuum cleaner's original user manual for specific troubleshooting steps or contact iLife customer support.
