Why Roomba Sensors Not Working Affects Brushes

Not many users think about the sensor's impact on cleaning performance. When the Roomba sensors not working, they can result in navigation problems, as well as Roomba brushes not spinning.

Sensors are the Roomba's eyes, with which it can detect furniture, walls, and floor surfaces. When they are out of order, the Roomba simply can't trigger the brush actions for something on the rugs, carpets, or floor types. In extreme cases, the Roomba spins in circles or comes to a halt almost mid-cycle, leaving the place dirty.

Here following could be why sensors fail:

Dust Accumulation: Dust and dirt block sensor signals.

Scratches or Wear: Some older Roombas would indeed have been put through a lot with their sensors.

Software Issues: Sometimes sensors fail to respond due to internal errors.

The brushes may also appear inactive when sensors aren't working. Try these fixes before thinking the motor is broken:

Cleaning the Sensors: Use a microfiber cloth to wipe sensors gently. Avoid any liquid cleaners, as moisture could harm the sensors.

Resetting the Device: It is important to know how to reset the unit here, because often this works to recalibrate the sensors and restore brush operation.

Verify for Updates: If you have the iRobot app, you will want to make sure your Roomba is updated with the latest firmware because software updates tend to repair issues with sensors. 

Examine Each Brush Individually: Even if the sensors are functioning, you will want to check for hair or debris lodged in the brush rollers. 

If the same issue persists, you may need replacement sensors. You should purchase genuine iRobot parts, as they may be the most durable and fit well.

Preventive maintenance keeps sensors working. Clean them once a month, and do a reset of your Roomba, every now and then, especially along with the cleaning. Regular cleaning and doing a reset is a good way to reduce the chances of both the Roomba Sensors not working and the Roomba Brushes not spinning. 

A well-kept Roomba means it cleans more effectively, has a longer life span, and is less of a headache for you. By working on sensors and brushes together, you can be sure that your iRobot will continue to deliver "spotless" results on every surface.
