Maintenance and Adjustment
Cleaning the Jet Tubes
Verro uses two powerful jets of water like power washers to loosen attached
dirt and debris as it moves around the pool. If the tubes that carry these
jets from the impeller to the nozzles under the robot become blocked, Verro
will not be able to clean as well. If Verro is not doing a good job of loosening
attached dirt, and other measures (cleaning the filter, inspecting the vacuum
intakes, etc.) have not worked, check the tubes.

Unplug the Power Supply. (Please keep the plug away from contact
with water.) Unplug the floating power cord from the Power Supply.

Examine the clear tubes for obstructions.

Remove the tube by pulling it from the holders at each end. The
tubes are not glued in place.

Clear any blockage by flushing the tube with cold water.

Reinsert the tube into the holders at each end (do not use any form
of lubricant other than water).
