Frequently Asked Questions
A: The most common wear-and-tear parts that require periodic replacement are the brushes, gears, and bearings. These parts are subject to the most friction and pressure during regular operation.
A: Brush lifespan depends heavily on usage frequency, floor type, and maintenance. A general guideline is to replace cylindrical brushes when the bristle length is worn down to about ½ inch (1 cm). You may also notice that more passes are needed to clean the same area effectively, which is a sign of wear.
A: No, parts are machine-specific. Ensure you order brushes and other parts that are compatible with your specific model (e.g., TM4 vs. TM5) and serial number. Using the wrong brush type for a specific carpet can also cause added friction and damage to the machine.
A: You can order parts through CRB distribution partners or directly via email at orders@crbclean.com. Schematics and part lists may also be available on the manufacturer's or supplier's website.
A: Gear failure often stems from excessive friction and pressure. Common causes include: Too much pressure on the brushes for extended periods. Bent axle rods (which can happen if the machine is dropped or handled carelessly). Debris and hair buildup in the brush chamber, which increases resistance. Lack of lubrication for the gears and bearings.
A: Regular greasing is essential to prevent heat buildup and damage. It is recommended to perform this maintenance every 90 days to 6 months, depending on usage. Use a specified lubricant, such as white lithium grease.
