Designed for family recreation and swim training, Swii combines the stability of a highly buoyant kickboard with smooth dual-propeller assistance. Two speed modes at 0.6 / 1.0 m/s (1.34 / 2.24 mph), intuitive two-hand control, and support for users up to 100 kg (220.5 lb) make it easy to enjoy in pools and calm water.
Buoyancy & Control — A stable kickboard-style design supports developing swimmers, while two speed modes adapt from gentle practice to faster recreational use.
Smart Safety — Multi-color status lights show battery and operating status, while SublueGo supports speed control, child safety lock, indicator-light settings, and self-cleaning.
Battery & Runtime — Every standard Swii includes 1 removable 98 Wh battery, providing up to 30 minutes of normal use. The 98 Wh battery is no longer offered as an additional battery option.
Extra Battery Option — The current “+ Extra Battery” option adds 1 removable 158 Wh battery, providing up to 45 minutes of normal use when installed. This is in addition to the included 98 Wh battery, for 2 batteries total.
