SIDE BRUSH Module inspection and cleaning
If side brush is going backwards then the side brush module has entered anti-tassel behavior.
The side brush may spin slowly or briefly spin backwards in order to escape from carpet tassels
or wires. The robot may occasionally enter this behavior on thick or high-pile carpets. This is
normal. If it occurred when there were no tassels or wires, proceed with inspection.
Use a Philip’s screwdriver to remove the side brush and clear away all hair and debris that is
wrapped around the hex shaft.
If the side brush does not spin after cleaning, replace side brush module.
