the 6101 replaces both the 6000 and 6100. It has a switchable DC laptop pc style power supply(which replaces the heavy "hockey puck" AC power supply) which changes the voltage so that pump will run at approx the low and high speed of a 6000 or that of a 6100. The electronics that were in the external silver driver box have mostly been moved inside the pump as well, thus eliminating said box.... overall a much less bulky setup.
