Make sure the batteries are inserted in the correct orientation. If there is a low flow, shake the unit in water to dislodge trapped air.
Always ensure the item is fully dried prior to storage.
NOTE If the vac isn’t pulling detritus out of the water, ensure that the cleaner is dug into the gravel, then lifted up to let the gravel fall out. Then repeat. Ensure a good brand of battery is used
