The ERA TEC is consistently continuing the innovative ERA series, thereby guaranteeing top performance at an incredibly quiet 49 dB in ECO mode. The TEC can therefore be used around the clock, at any time of the day, even in busy and sensitive areas, such as hotels or in office rooms. 
Should it be necessary, the spare filter bag compartment saves unnecessary legwork and loss of valuable working time should no replacement filter bags be close at hand. 
The standard USB port and the optional storage box allow you to charge your mobile phone directly on the vacuum cleaner without setting aside your mobile anywhere on the property or losing sight of it. Alternatively, the storage box is also suitable as a practical beverage holder, for cleaning agents, or for carrying microfiber cloths. 
The fill level indicator in red indicates that the filter bag needs to be changed or clogging.
