I was skeptical about purchasing a canister vacuum to clean my laboratory but the Bissell Butler Revolution exceeded my expectations .As a result of my tests, I determined that it has fantastic suction power and easily picks up dust and debris from even the hardest to reach spaces. The filter is also easy to clean and maintain. The only downside is that it is a bit heavy, but that is expected for an industrial-grade vacuum. Overall, I highly recommend this vacuum for anyone in need of a durable and reliable cleaning machine..
