Mirka Ceros here as well and two Air Vantage electrics. To the post that says they overheat and turn off.. your operators are making the cardinal mistake of bearing down on the sander. I have an employee who constantly has to be reminded that you dont bear down on a sander. They sand better/faster with pretty much zero pressure (faster pad speed/no bogging). Its understood that other electrics dont have this protection but companies like Festool have been endlessly trying to educate owners not to bog/bear down on sanders for years with the sharpie on the pad protocol.
I have a 5" and 6" Airvantage electric and two Mirka Ceros and the biggest nuisance with the Airvantage for us is the fact that it times out on non-use and having to hit the up button on the sander to wake it up after 5 minutes of sitting. I understand the logic there but it'd be nice to be able to shut it off.
Ive sanded with the Airvantage sanders for 10 hours a day and never once had one cut off on overheat. I will say they get warmer than the Mirka's but Ive never had one cut off. Now... put the exact same sander in the hands of "impatient Arthur" who refuses to stop bearing down on the sander and tipping it on edge to dig out a defect, and he will trip that sander on overheat in 5 minutes.
In my world the overheat cutoff is a bit of a blessing because it lets me know who to take off the sanding station ASAP.
