Model issues and repair guidance
Use the compact width to map a pickup fault across the floor rather than treating every missed strip as low vacuum suction. Confirm flow at the pipe, clear the neck and cross-channel, then inspect dry brush strips or wet rubber blades for equal seating and wear. A repeating trail beside one wheel points to insert height, axle, or body alignment. If the whole mouth loses pull only while turning, inspect the neck opening and gasket for an angle-sensitive leak.Confirm pipe flow, clear neck and cross-channel, then inspect dry brushes or wet blades for equal seating. A trail beside one wheel points to insert height, axle, or body alignment. Turn-only whole-mouth loss directs service to neck opening and connection gasket.
