The Charging Base is a great add-on to the WOW Too! 

This base allows the unit to be stored vertically which saves space, charges the battery in the WOW Too, and charges 1 additional battery. A must-have companion to go with the WOW Too!

Directions:
Pull out the rubber cap and turn it until the whole charging port is revealed. Plug the charger into the charging port.

Note:
• Overcharging the battery may cause damage.
• Avoid charging for more than 5 hours.
• Use the original adapter and battery.
• Fully charge mop prior to first use.
