Electrolux Quiet Clean Power Unit PU3900C

Yes, this is a hybrid unit. You can choose to use it as a bagless system or install a bag for easier, cleaner disposal of debris.

You do not need to replace it. The unit features a permanent, self-cleaning HEPA filter designed to maintain performance without the need for recurring maintenance or new parts.

The PU3900C is engineered for quiet operation and includes a built-in muffler, keeping noise levels below 70 dB. While it is significantly quieter than a standard portable vacuum, it is best installed in a basement, garage, or utility closet for optimal noise reduction.

The integrated LCD display allows you to monitor the system's overall performance in real-time. It provides helpful alerts, such as notifying you when the 7-gallon collection tank has reached capacity and needs to be emptied.

With 640 air watts of power, this unit is rated to effectively clean homes up to 12,000 square feet. The motor soft start system also helps extend the lifespan of the motor by reducing stress during the initial power-up.

The utility inlet is located directly on the power unit itself, allowing you to plug a hose into the vacuum in the garage or basement. This is convenient for cleaning your car, workbench, or the immediate area around the unit without needing a separate wall-mounted inlet.
