What could be improved, is the connection of the hose to the vacuum cleaner. Although Included is a connection piece for the garden hose, but every time the Gardena hose connection unscrew the garden hose and insert the hose on the connector from the vacuum cleaner is a little bit cumbersome. I recommend a Gardena adapter connector with external thread, which can be n the sucker purely screw (with internal thread). Then can the hose with Gardena adapters connect cleanly and quickly. But that in itself has nothing to do basically with the product. Is a suggestion which also means no star deduction for me. Top product. Buy recommendation.
