Vacuums tend to be noise generators (though I don't know what the
spectrum is). The other devices will sink the signal (attenuate).

IMO the problem is the lack of understanding of the problem not the
product. Don't worry most people think it's noise on the line when
most times (but not always) its signal loss. The problem is that the
device is acting as a black hole (signals go into the device and don't
come out). A filter will make the device look like a high impedance
device to X10 frequencies (harder for the X10 signal to enter) and
less signal loss will occur. It's a low impedence device to the AC
(50/60 Hz).

And your using x10 ... one has to wonder. ;-)
