I have also been using my Maxxt professionally for several months. None of the problems described in other reviews occurred. I paid 150 Swiss francs (170 USD), a Festool would cost over three times as much. Until further notice, an excellent product.
I think they hook it right into the vacuum itself. Some vacuum design has a built in outlet. This can affect the sanders because the vacuum machine itself can give out insufficient current. This can cause sanders to have issues.
It’s still running great. But if share circuits same with the vacuum. The vacuum will have issues not the sander. And think I’ve figured out why. I’ll make another video about it soon. Vacuum pull a lot of electric especially when the filter is pack up. The sander run on brushless motor. It needs a constant power supply. By splitting between both vacuum and sanding. One will lose the constant power flow. Causing motor issues on vacuum. So now I run a straight home run for only sanders. No more issues
