Shark ION Robot 750 Troubleshooting

The device’s cleaning performance is hindered by blockages, obstructions, or damage to the equipment, resulting in hair, crumbs, and debris left behind as the vacuum is operating.

Begin by removing dust and debris clogging the Shark ION Robot R750 and obstructing its airway. Inspect the device’s brushes, rollers, and additional cleaning attachments for debris and blockages causing a reduction in suction force. After inspection, remove the blockages from the cleaning attachments.

Inspect the Shark ION Robot R750 for visible holes and damages that are causing air leakages and a reduction in suction force.

Turn in your Shark and listen for the sound of rattling from the motor. If you hear rattling, the motor is broken or the torque gear may be displaced.

The device’s inability to recharge on the dock station inhibits its cleaning capabilities.

Before troubleshooting device battery, ensure you are exclusively using the Shark ION Robot R750 charger and battery. Other charger and battery types may burst in contact with the Shark ION Robot R750, leading to potential injury to the body or damage to the device.

Once the charger and battery type is correct, plug the Shark ION Robot R750 from the power outlet and plug back in to reset the robot vacuum. If the device does not charge, move forward with troubleshooting steps.

Unplug the Shark ION R750 from the power outlet. Clean all charging contact points on the robot vacuum and the charging port with a dry microfiber cloth and reposition the battery.

Plug the Shark ION Robot R750 into the power outlet to test the device’s ability to locate the charging dock. Realign the device to the charging dock on two the metal connecting points. Remove and allow the Robot to locate the charging dock. Repeat process until it locates the dock independently. Once the device attaches to the charging port the indicator lights on the vacuum will illuminate the robot and will produce an audible indicator that the Shark is connected to and actively charging on the charging dock.

If the vacuum is running into objects, not moving properly, or moving erratically, this could be your problem.

If you suspect a broken sensor on your Shark ION R750 vacuum, start by checking for the following problems:

If the vacuum no longer avoids objects or doesn't change direction as it should, the sensor responsible for obstacle detection may be damaged.

If the vacuum starts moving erratically, for example spinning in circles or failing to navigate properly, this could be due to sensor malfunctions.

If your LED lights or status indicators aren't working correctly or not responding, it may indicate a sensor issue.

To access the sensors, you'll need to remove the cover and get to the motherboard. Make sure the vacuum is completely powered off before you do this. If cleaning the sensor doesn't work, you may need to replace it.

If the vacuum fails to direct its way or runs in the same space but still functions, it may experience an error with the main wheel.

Before fixing any wheels, ensure to check if your robot can move on another surface. The improper direction can be due to a bumpy surface or uneven level.

If you have moved the vacuum to a flat surface but are still unable to manipulate it, there may be something clogging around the nave (like hair, small fabrics, or webs). Under a serious clogging situation, the wheel may fall off or increase the friction, causing the robot vacuum to be flicked off on the way and be broken. You must unplug all electric sources to the vacuum and place it on a sturdy table before cleaning the wheel. After using guided kits to disassemble the wheel from the vacuum, you are now able to clean the wheel.

As the wheels are detachable for other purposes, you have not put them in the right position since the last time you took them out. You can try taking them out again and read the guidelines to assemble them appropriately.

The robot vacuum is still unable to move as it should even though the wheels are clean and in the right spot. This may be caused by defects in the motherboard. Please check throughout all the possible causes before you get to this conclusion of a flawed motherboard since its reparation steps are harder to process. Failure to repair a motherboard can cause serious damage to your device. To repair the motherboard of the robot, you disconnect the robot power and use the guided kits to unscrew the outer shell. When you get to the place of the motherboard, carefully remove the connected wires and observe the motherboard. This observance allows you to point out what actually happens to the motherboard. If there is dust on the board, try to wipe it with cotton swaps or a soft brush. A dusty motherboard may create electrostatics when the power is on, causing the robot to function abnormally. If you feel the moisture or see any burn components on the motherboard, you need to replace a new motherboard.

LED Lights aren't turning on or isn't flashing correctly.

Press the power button to see if you can get a response from the LED Lights

If you don’t get a response from the LED Lights, you should put the vacuum on a charging dock

If a Clean red or max light is flashing, the robot is probably stuck

Try taking the robot and moving it to a different location

Once the robot is in a new location, go inspect the bumper and check for any problems

If the light continues to flash, even if you’ve seen no problems, remove front caster wheel and clean wheel housing
