You can use!
Any of my pictures, of vacuums that is..LOL! That Apex is strangely quiet, about like a Filter Queen, if you notice, the motor brushes are not pushed by springs, but rather pulled from either side by the springs, also, another oddity, the bearings are above the commutator like most motors, but on the other side of the fan at the end of the shaft, under a cover on the fan housing...odd, but it really works!
