When I first purchased the Tigershark QC, it didn't move for like 10 minutes or more and I was told it was mapping the pool.
I found later in the season I wasn't happy with the performance and then it stopped climbing walls, it has since been repaired.
Although after the repair I expected it to re-map and I don't think it has.
1. How do I force a re-map?
2. How do I remove the unit from the water without some dirt getting thrown back in? first I find it hasrd to remove, I kind of hold it up a little so some water can drain and hen I pull it up and the pressure of the water will send some dirt back in.
3. I read other another post that said there unit was smart enough to stop getting stuck on the main drains (I have 2 of them), but mine still does sometimes but it is has improved since I put that lifter on the bottom but it can still happen.
4. I also find my unit does not work systematically, it doesn't get every spot or sometimes misses the entire area or won't climb all the walls.
Overall I haven't been that happy and sometimes I find just getting out the Vacuum is easier and faster.
I do move that lever to the other side each time I use it, I do clean the filter after almost every use.
Appreciate anything you can tell me to get better use of it as Pool season starts real soon for me.
