Seagull Pro gets confused- rotates in place

[gcip]

I got a new Seagull Pro the other day to replace my Polaris 380 (booster died). At first it seemed to work right, then it stopped in the deep end and just started rotating. I don’t have any bottom drains.
Took it out and charged, tried again this time in wall+bottom. Was doing a nice job on the water line, then gut hung up in one corner and stayed there until the power drained. Never got to the bottom. It sat in one place for 5 full minutes, moved forward a few feet and started spinning again, Comments appreciated.
Tried again in bottom mode, again eventually started spinning. It’s like it is confused about where to go. BTW there were no obstructions or tangled stuff in the wheels.
Aiper thinks I have a defective unit and will replace it, I will repost when I get the replacement.
I paid $499 on the Aiper site and noticed that Leslie’s has it for $249 (so does Intheswim). Has anyone gotten one of these? I wonder if they are the recalled version?

Sorry to hear you’re having problems. Aiper customer service has been the bane of my robotic equipment-owning existence. Hopefully they send you the replacement quickly, as it does sound defective from the behavior you described.
The recalled units all start with SN61 and were sold from 5/23-5/24, according to their website:

I have a refurbished replacement unit from Aiper that has a date code of 4/24 and a serial starting with SN62 (blue charge port cover). Both Seagull Pro units I’ve had seem to have a Roomba-like pattern to cleaning, so they do get confused in places if the pool is not perfectly rectangular. I did have to remove the risers from my bottom two drains, and also I find it gets stuck less there if I run it while the pool pump is off for the evening. The newest units seem to have a 5th wheel on the bottom to prevent grounding themselves on a drain cover.

I ran it a couple of times yesterday, it was much happier (no spinning). It may be a coincidence but I started in the shallow end this time. Did a good job cleaning, I’d guess 95+% of the bottom.
I have a Waybot C2 vision coming tomorrow. Will post a comparison. I plan to return the one that loses…
BTW so far Aiper has been pretty responsive and sent a return label for the defective unit. Hopefully they will process the refund quickly.
