Bos Clean XLi is suitable for creating negative pressure in very large areas and surfaces.
Despite its large size, the device is very lightweight and easy to move.
The device is equipped with smooth-moving rubber wheels to minimize surface damage during movement.

Bos Clean XLi power is adjustable using the control panel show in the image.
The negative pressure devices in the Bos Clean series feature an electronic sensor that notifies the user when the filter is clogged and needs to be replaced.
Thanks to quick-connect mechanisms, replacing filters is very simple and fast.
Additionally, various filters can be combined, such as HEPA filters. To extend the life of the HEPA filter, a pre-filter chamber can be installed to prevent larger particles from reaching the HEPA filter.
