Pros:Brush cartridge can be easily removed for cleaning.
Cons:Gears connecting to brush cartridge is cheap plastic that can easily get stripped.
Overall I do like the design of the product. Nevertheless, the cheap plastic gears used to rotate the brush can easily get stripped. This results in the brushes no longer turning. I contacted Bissell and they informed me that there is no replacement part for this component. I have had this product for approximately 2 1/2 years with moderate use. Doesn't make sense that I have to throw away a perfectly good small appliance simply because one of the small components fails.
As mentioned by other reviewers, the suction is only so-so. As a result, the consumer has to press hard with the machine on the carpet to suck up the cleaning solution. It is possible that having to press so hard, could put pressure on the brush component which can eventually strip the gear. Another root cause of the gear stripping could be removing the brush cartridge to clean it and not inserting it back with force to connect the gears with the spokes on the brush cartridge.
