The Hayden 81SV90 SuperVac central vacuum bagless power unit is no longer available. The recommended replacement is the Valet ATQ-180. This unit is also bagless and has even more power.
The 81SV90 is recommended for large homes. This unit has been designed for first-rate filtration. The primary filtration is cyclonic. A cyclonic separator cone is utilized to increase filter efficiency when separating dirt from the air. The secondary filtration is a washable cartridge filter.
The SuperVac 9000 has a VacTrack Prompting System. This shows the user when to clean the filter, when to empty the dirt canister, and when to service the motor.
