In readiness for little manual intervention highly recommended

In our gutter (half-round, about 12 cm internal diameter, covered by the roof tiles a little more than half) I had to use the little paddle, as the long through ongoing contact with the roof tiles the unit after a short distance brought repeatedly to tip ,

After installation the short paddle that is rarely done, and it was easy to fix: By switching the direction of rotation of the paddles, the unit has set up immediately.

The gutters were very dirty. The automatic function has nevertheless cleaned properly but needs through ongoing reset actions more time. Slightly soiled areas we therefore recommend the much faster manual control.

I share the good suggestion of a previous reviewer: At the rear of a thin rope should be attached so that you can retrieve the device after work faster. An eyelet for this exists.

A good buy that will help prevent a lot of unpleasant and somewhat dangerous work. A note at the end: The two AAA batteries for the remote control in the handle are not included, so secure in good time!
