To avid short circuits when replacing the batteries, always first remove the connector from the minus pole of the battery connected to the robot. Consequently, always reconnect this pole last.

The batteries must be recharged in a well-ventilated area free of flammable materials.

Keep the battery tops clean.

The batteries included with the robot are two 12 V AGM type lead acid batteries with 100 Ah capacity (part no 909244). If replaced, it's important that the batteries have the correct size and weight. Are the batteries significantly bigger they will not fit. If they are lighter there is a risk that the robot will overturn due to the too low weight.

Weight: 27 kg
Length: 330 mm
Width: 173 mm
Height: 237 mm

Compared with standard lead acid batteries, AGM type batteries are more durable and have a longer life span.

The charger included is a 24 V 12 A charger which plugs directly into the robot. It is available in both a 230 VAC version and a 115 VAC version.

1. When charging the batteries, the robot must be switched off. The batteries cannot be charged when the robot is on. .

2. The charger must be connected to the robot first. .

3. Then connect to the wall outlet. .

4. When the charger is connected to the wall outlet only the orange status light should be turned on. See the charger manual for details.

The robot shall always be connected to the charger when not used, in order to prolong battery life. Do not let the robot stay with low charge level for any prolonged time as this damages the batteries and shortens battery lifespan. Continued use after battery low warnings will also damage the batteries.

If the robot has warned for low battery, charge it for at least the same amount of time that it has previously been washing before using it again.
