Abstract: A muffler for an autonomous vacuum includes one or more chambers and one or more noise-absorbing elements for noise reduction of air exhausted into an external environment of the autonomous vacuum. The muffler is coupled to a vacuum stack inclusive of a vacuum motor. The muffler includes a main body, a foam layer, and a sealing plate. The main body includes an inlet for air exhausted by the vacuum motor and forms the one or more chambers fluidically connected to the inlet. The foam layer is disposed within one of the chambers of the main body. The foam layer absorbs sound waves incident on the foam layer. The sealing plate is affixed to the main body and includes an outlet to exhaust air from the chambers to an external environment of the autonomous vacuum.
