Using your Bosch Readyy'y brush roller is easy. Just install it into your compatible handheld cordless stick vacuum. When vacuuming, move the vacuum slowly over the surface to let the brush roller do its job. As for maintenance, regularly check the brush roller for any tangled hair or debris. You can use a pair of scissors to carefully cut away any hair wrapped around it. Avoid using the brush roller on wet surfaces as this may damage it. Store the roller in a dry place when not in use. If you notice any significant wear and tear, it's time to replace the brush roller to keep your vacuum working at its best.
