Question: Are the soft white brushes that are supplied with the machine OK to use on wool, jute, sisal, and silk rugs?
Answer: The factory performed a change on brushes. The original design was to include a white soft brush for home carpet and natural fiber area rugs. These have been changed out, by default now you receive blue brushes that are both home wall to wall carpet and will also clean commercial carpeting. The white brushes (now optional) on the TM4 and TM5 do just fine on natural fibers, however, I do try brushes on any small area of the carpet or rug prior to performing the actual cleaning job.

Preventive Maintenance on CRB Machines
Between each job, remove the brushes and wipe out the crud under the brush cover and by the bearings. (Use box rags, thick paper towel)
At the end of the day after all jobs, use a cleaner such as Mr. Clean, Windex or a possible disinfectant with a scrub brush and wipe down with box rags.
Make sure the bearings on the non-gear side spin freely, the moment they begin to not spin freely; it can torque the gear side and cause the gears to break. You will need to replace the non-gear side bearings as soon as they stop spinning freely. Important to check this on a weekly basis.
Cleaning of Brushes: Take a 5-gallon bucket full of hot water and place the brushes in it. It will normally turn extremely black. Empty out the 5-gallon bucket and repeat. For extreme rat nasty with some brushes, you may need to repeat this process 6-7 times. The avg. time it takes per bucket full of hot water is 45 mins. During the final soak pour a few ounces of disinfectant and let it sit for 30-60 mins. Remove from bucket, set in front of fan and let dry.
Remember the brushes get full of crud, dirt and debris and that overtime you don’t get as good as a clean. As the brush spins, all the crud collects on the black tube and it collects on the bristles from the inside moving out. However, if you constantly clean the brushes at the end of the day, they stay almost brand new for an incredibly long period of time.
Note: It can take up to 2 days for the dirtiest of brushes as you repeat the bucket of hot water process 6-7 times. It is recommend you do the process as much as needed until the water does not change colors. Also, if you do not properly clean after every job, the crud builds up and the gears work harder since the brush has to fight against the built up crud and this can cause the gears to break.
Brush Rotation: Do not rotate the brushes from front to back. Since the brushes are soaked in hot water, it takes the memory out of that brush. However, if you use the machine for a long period of time, you will need to flip the brush but not front to back, only the other way around. It is important to remember that the brushes have a natural curve to the bristles tips and the bristles form “a memory” after constant use. You will need to rotate the brushes so the memory goes the opposite direction and begins to clean better.
Note: In order to tell when this happens, pay close attention to the cleaning results. If the results become mediocre, then flip the brushes.
Insert some grease between the bearing and the cover and the bearing shaft entrance every month.
Every 3 months, remove the gear cover, clean the gears and re-grease with white lithium grease.
Make it a habit to remove the bearing cover every month to clean it up well with W-40 and make sure to dry it with compressed air and fit the cover together again.
