Machine vibrates excessively or feels unstable while cleaning

Safety first: Unplug the unit before inspecting the underside.

• Inspect brushbar: Remove the brushbar and check for clumps of hair or debris on one side that could cause imbalance. Clean thoroughly.
• Check bristle wear: If bristles are heavily worn on one side only, replace the brushbar to restore balance.
• Examine wheels: Spin each wheel by hand. Look for flat spots, cracks, or wobble. Replace damaged wheels.
• Tighten fasteners: Check all visible screws on the floorhead and chassis. Tighten any that are loose, but do not overtighten into plastic.
• Test on flat surface: After reassembly, test the machine on a flat, even carpet to confirm vibration is reduced.
