This is a new 2019 model of the popular SpinClean pressurised filter at a super low price.
With this pond filter keeping your pond clean and healthy becomes a doddle. Once the filter sponges get full of dirt an indicator pops up alerting you that it's time for a clean. Simply switch the blue dial from 'pond' to 'waste'. Turn the cleaning handle to agitate the internal sponges to dislodge dirt and debris and watch it run away to waste. Once clean simply return control dial to the 'pond' position.
