Abstract
A cleaning system may have a brush roller that moves dust and debris towards a duct opening for collection. The cleaning system may be an autonomous vacuum robot or include an autonomous vacuum robot. The cleaning system may include guards that reduce the likelihood that fibrous debris wraps around rotating portions of the brush roller (e.g., around a drive pinion). Buffer zones in the brush roller may receive fibrous debris that would otherwise wrap around the brush roller and increase undesirable friction during operation. The brush roller is configured to be unlocked from a position contacting the inner surface of a cleaning head of the cleaning system. The fibrous debris stored in the buffer zones may be suctioned into a debris collection compartment of the cleaning system after the brush roller is unlocked. The cleaning system includes a wedge to seal a cavity for ingesting debris within the cleaning head from the environment.
