Letro Legend floating, not making contact with bottom

[kevbach]

I have a 5 yr old letro legend cleaner that lately hasnt been cleaning very well. The front wheels never really make contact with the pool bottom, almost like its doing wheelies, which I think it preventing good suction. The wheels seem to be moving at the proper speed, and have plenty of torque. The water pressure also seems right, plenty of water coming out of the jets. Cant figure out why those two wheels wont come down . Any ideas?

I do not have a letro but when my dolphin does that it is ALWAYS because there is air trapped inside the machine.

Thats interesting becasue I thought I did see air bubles escaping from the cleaner. Any ideas on how air is entering the system?

Air enters a pump system on the suction side of your main pump as the most likely source. I am not at all sure of this but I think it could be also entering on the suction side of the booster pump.

Posting a pic of your main pump that includes a wide enough shot to get your booster pump as well would be helpful.
