Red LED on the motorised floor head; brush bar stops spinning while suction continues.

Safety first: Remove the battery before working on the floor head. Never put fingers near the brush while power is connected.

Steps to try:

• Remove brush bar: Unlock the end cap or release latch on the Gtech floor head and slide the brush bar out.
• Clear obstructions: Cut away hair, string, and threads with scissors. Remove any debris lodged in the brush housing or around the end bearings.
• Check rotation: Spin the brush bar by hand. It should rotate freely without grinding or stiffness. If tight, the end bearings may be worn.
• Inspect drive belt/gear: On some models, a small belt or gear drives the brush. Check for broken teeth or a snapped belt.
• Test again: Reassemble and test. If the red LED returns quickly and the brush stops, replace the brush bar or complete motorised floor head assembly.
