The nozzle set "Auto-Set IZ400" is designed as a hoover accessory for Shark hoovers, specially supplied as a nozzle set and in one piece. It is compatible with models in the Shark IZ400 series that are equipped with DuoClean technology. The Shark Power Duo Clean Detect is a different model with its own DuoClean Detect nozzle and special sensors. There is no direct indication that the "Auto-Set IZ400" nozzle set is specifically suitable for the Shark Power Duo Clean Detect. It is therefore very likely that the "Auto-Set IZ400" nozzle set is not compatible with the Shark Power Duo Clean Detect, as it is intended for the IZ400 series, which differs technically and in terms of accessories from the Power Duo Clean Detect series.

The car set IZ400 is compatible with the Shark IZ300 model. Accessories like chargers and parts for IZ400 are generally compatible with IZ300 and IZ320 series as well.
