- Locate the cleaning cloth attachment area on the underside of the robot.
- Remove the used cleaning cloths by detaching them from the hook-and-loop fasteners or clips.
- Align the new cleaning cloths with the attachment area and firmly press them onto the hook-and-loop fasteners or secure them with the clips. Ensure they are flat and securely attached.
3.2. Side Brush Installation

Shown here are two side brushes, featuring blue bases and black bristles, which are crucial for sweeping debris into the robot vacuum's path.
- Turn the robot vacuum upside down to access the side brush compartments.
- Gently pull the old side brush upwards to remove it from its post.
- Align the new side brush with the hexagonal post and push it down firmly until it clicks into place. Ensure the brush rotates freely.
3.3. High-Efficiency Filter Installation

- Open the dustbin cover on your HOBOT LEGEE robot.
- Remove the dustbin from the robot.
- Locate the filter compartment within the dustbin. Remove the old high-efficiency filter.
- Insert the new high-efficiency filter into the compartment, ensuring it fits snugly.
- Close the dustbin cover and reinsert the dustbin into the robot.
3.4. Spray Nozzle and Screen Filter Installation
The spray nozzles and screen filter are located within the water tank system. Refer to your main HOBOT LEGEE user manual for specific instructions on accessing and replacing these components. Generally, this involves:
- Removing the water tank from the robot.
- Carefully detaching the old spray nozzles and screen filter.
- Installing the new spray nozzles and screen filter, ensuring a secure fit to prevent leaks.
- Reinstalling the water tank into the robot.
4. Usage and Replacement Schedule
To maintain optimal cleaning performance, adhere to the following general replacement guidelines. Actual replacement frequency may vary based on usage and environment.
- Cleaning Cloths: Replace every 1-3 months, or when visibly worn or cleaning performance diminishes.
- Side Brushes: Replace every 3-6 months, or when bristles are bent, damaged, or cleaning effectiveness is reduced.
- High-Efficiency Filters: Replace every 3-6 months, or when suction power decreases or the filter appears clogged.
- Spray Nozzles and Screen Filter: Replace as needed, typically when water spray is inconsistent or blocked.
5. Care and Maintenance
- Cleaning Cloths: After each use, remove and wash the cleaning cloths. They can be hand-washed or machine-washed with mild detergent. Air dry completely before reattaching.
- Side Brushes: Periodically check side brushes for tangled hair or debris. Use scissors to carefully cut away any tangled material.
- High-Efficiency Filters: Tap the filter gently over a trash can to remove loose dust. Do not wash the high-efficiency filter with water, as this can damage the filter material.
- Spray Nozzles: If spray is inconsistent, gently clean the nozzle openings with a small brush or pin to remove any mineral deposits or blockages.
6. Troubleshooting
If you experience issues after replacing consumables, consider the following:
- Poor Cleaning Performance: Ensure cleaning cloths are clean and properly attached. Check side brushes for tangles or damage. Verify the high-efficiency filter is not clogged.
- Reduced Suction: A clogged high-efficiency filter is a common cause. Replace the filter if tapping out dust does not restore suction.
- No Water Spray: Check if the water tank is filled. Ensure spray nozzles are clear of blockages and the screen filter is clean.
- Unusual Noises: Inspect side brushes for foreign objects or improper installation.
If problems persist, refer to your main HOBOT LEGEE robot vacuum user manual or contact customer support.
