Questions and answers
tiger shark wont go to bottom of pool, stays on surface with water pumping out of the top
The Hayward TigerShark may not be sinking because air inside the unit is not being released properly. When placing the TigerShark in the pool, it should slowly sink as air escapes. If it remains on the surface while water pumps out of the top, it may still have trapped air preventing it from submerging. Try submersing it by hand to help release the air.

Робот-пылесос слабо втягивает мусор со дна бассейна, в чем причина?
my tigershark qc will not climb the walls of my pool and seems to get stuck were the walls meet the floor. this junction is rounded
Does the pool water have to be a certain minimum temperature before the TigerShark will operate? I have two TigerShark pool cleaners and neither will operate. The voltage to the inlet of the power cord is roughly 25 VDC.
Tiger shark starts, runs a very short distance of a few feet, stops, tries to go back the other way a couple feet and then stops completely. When I have it out and try to manually roll the sweeps the two track belts “pop” every so often… Creating resistance. Is the belt off track or have the teeth worn down and new belts are needed? What else could be the issue?
