The Turbo T4 has the same quick cleaning state of the art technology as the Turbo T2 and a remote control feature. The unit comes with a wireless 4-way remote control that allows you to guide the unit front, back, left and right. It is great for spot cleanups before your big pool party. Drop the robotic dynamo in you pool and it will be spotlessly cleaned in only 1 hour. Turbo T4 automatically shuts itself off after its 1 hour cleaning cycle is complete.
