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.

Abstract: An autonomous vacuum implements a semi-waterproof waste bag capable of collecting dry waste from vacuum debris and liquid waste from mopping. The autonomous vacuum leverages a dual-roller cleaning head, one for dry cleaning and another for wet cleaning. The autonomous vacuum utilizes vacuum force to ingest both dry waste and liquid waste from the cleaning head into the semi-waterproof waste bag. The semi-waterproof waste bag includes a non-permeable portion formed of a waterproof material and a permeable portion formed of an air-permeable material. The semi-waterproof waste bag may further include a water-absorbent material, e.g., water-absorbing spherical beads.
