No not at all. The spammer thinks his will though... pdk
I have another comment about this. 50% more 'powerful' should be replaced with 50% more 'efficient'. Why? With a regular shop vac the motor cooling air must come in through the hose and any restriction will heat the motor. With a central vac, if the motor is separate from the impeller housing, the motor will not heat up when all the ports are closed because there is no air to move! And so the motor runs cooler and draws less current lowering the cost of operating it. That should be the point in advertising it. Cheaper to run and convenient.... phil k. finally stepping down off the soapbox..
