Quiet series power unit based on the S5620 model. Unit features a muffler included in the box and new non-ventilated motor shroud with foam lining for an 8% overall reduction of motor noise (noise emitted where the unit is stored).

Other changes from the S5620 include a Teflon brand filter replacement for the Micro-Tex filter, new body color and movement of the utility valve on to the vacuum body instead of the remote mount utility valve of the S5620. All specifications, features and power ratings are otherwise identical to S5620 model. Upgrade from Hoover Hush S5615.
