The Protos turned out to be able to do more than just vacuum the floor. The November 1927 issue of the Siemens magazine says that this device could also be used for brushing dogs and horses, catching flies in the stable, cleaning duvets, keeping moths out of clothing, killing insects, spraying flowers, and removing dust from printer's drawers. It can also be connected to a parquet floor cleaner or sander.
The vacuum cleaner is attached to the green metal pipe. The 150 watt turbine and motor are fitted at the bottom, against the lid. A conical plastic disc is attached at the bottom of the motor to keep the dust bag in place during vacuuming.
