Why Your Shark RV850 Won’t Dock

Several factors can prevent your Shark RV850 from docking correctly. Addressing these issues promptly will not only solve the immediate problem but also extend the life of your robot vacuum. Here’s a breakdown of the common culprits:
- Obstructions: Physical barriers blocking the path between the robot and the dock.
- Sensor Issues: Dust or damage affecting the robot’s navigation sensors.
- Docking Station Problems: Incorrect placement, power issues, or physical damage to the dock.
- Battery Issues: A significantly degraded battery might not allow the robot to reach the dock.
- Software Glitches: Temporary software errors that disrupt normal operation.
Troubleshooting Steps for a Non-Docking Shark RV850
Here are detailed steps to diagnose and fix why your Shark RV850 isn’t docking:
1. Check for Obstructions
The Problem: The most common reason for docking failure is physical obstructions preventing the robot from reaching its base. These can include furniture, cables, or even small objects.
The Solution:
- Clear the Path: Ensure a clear, unobstructed path of at least 3 feet in front of the docking station and 1.5 feet on each side.
- Manage Cables: Secure loose cables and wires that might entangle the robot.
- Remove Small Objects: Pick up small items like socks, toys, or shoes that could impede its movement.
2. Inspect and Clean the Sensors
The Problem: The Shark RV850 relies on sensors to navigate and locate its dock. Dirty or damaged sensors can impair its ability to find the base.
The Solution:
- Locate the Sensors: Refer to your user manual to identify the location of the robot’s sensors (usually on the front and bottom).
- Clean Gently: Use a soft, dry cloth to gently wipe the sensors. Avoid using liquids or abrasive materials.
- Check for Damage: Inspect the sensors for any visible damage. If damaged, contact Shark customer support for repair options.
3. Verify Docking Station Placement and Power
The Problem: An improperly placed or unpowered docking station cannot guide the robot for docking or recharge it.
The Solution:
- Optimal Placement: Place the docking station on a hard, level surface against a wall. Avoid placing it on carpets or in areas with direct sunlight.
- Secure Connection: Ensure the power adapter is securely plugged into both the docking station and a working wall outlet.
- Test the Outlet: Verify the outlet is functioning by plugging in another device.
4. Reset the Robot Vacuum
The Problem: Software glitches can sometimes interfere with the robot’s ability to dock correctly.
The Solution:
- Locate the Power Switch: Find the power switch on your Shark RV850 (usually on the side or bottom).
- Power Cycle: Turn the power switch off, wait for about 10-20 seconds, and then turn it back on.
- Test Docking: Send the robot back to the dock to see if the reset has resolved the issue.
5. Examine the Battery Health
The Problem: A battery that’s significantly degraded might not hold enough charge for the robot to reach the docking station, especially in larger homes.
The Solution:
- Monitor Battery Life: Observe how long the robot runs before attempting to dock. If it’s significantly shorter than usual, the battery might be failing.
- Contact Support: Contact Shark customer support to inquire about battery replacement options.
- Consider Replacement: If the battery is old or severely depleted, replacing it might be the best solution.
6. Check the Bumper
The Problem: If the bumper is stuck or not moving freely, it can interfere with the docking process. The bumper helps the robot navigate and detect obstacles.
The Solution:
- Inspect the Bumper: Check the bumper for any obstructions or debris.
- Free the Bumper: Gently push and release the bumper to ensure it moves freely.
- Clean the Bumper: Wipe the bumper with a clean, dry cloth.
7. Software and Firmware Updates
The Problem: Outdated software can sometimes cause operational issues, including docking problems.
The Solution:
- Check for Updates: Use the SharkClean app to check for any available software or firmware updates for your RV850.
- Install Updates: If updates are available, follow the app’s instructions to install them.
- Restart the Robot: After updating, restart the robot to ensure the changes take effect.
Practical Elements
Tools/Materials:
- Soft, dry cloth
- Small brush (for cleaning crevices)
Preparation Steps:
- Ensure the area around the docking station is clear.
- Turn off the robot before cleaning any components.
