If the roller brush of your E20 robot vacuum isn't spinning, please refer to the common causes and their respective solutions below:

Common Causes

1. Due to the strong suction of the vacuum cleaner, lightweight carpets may be sucked into the brush roll chamber, causing the brush roll to become blocked and stop rotating.

2. Thick, high-pile carpets may also prevent the roller brush from spinning. The heavy fibers in these carpets can create excessive resistance, hindering the proper rotation of the roller brush.

Solutions

1. Use a soft roller brush: Consider contacting us to purchase a soft roller brush designed for thick or plush carpets, as it may help minimize the chances of the brush failing to spin properly.

2. Inspect for blockages: Ensure that the roller brush does not have entangled strands that might prevent it from spinning.

3. Reduce suction level: Press the vacuum cleaner button briefly to switch modes.

Furthermore, we recommend regularly cleaning the brush and removing any hair, fibers, or debris that might have built up, as this can help ensure the robot vacuum's optimal performance.
