Tax return money got me a neat Sebo "D" series vacuum that replaces the 3.1 airbelt machines.this one is really nice-more effective and uses Filtrete bags instead of paper.It has two filters-motor safety filter in the bag compartment lid and a HEPA style filter under the machine in the base.-after the motor.The vacuum has variable speed contolled from the canister or the hose handle.I rather like this vac-could be another daily driver canister along with my TriStar.The machine came with the ET-1 powernozzle.Both the powernozzle and vacuum are black in color.when the vacuum is turned on-the speed control dial on the canister also acts as the on-off switch when the knob is pressed.A blue LED light orbits around the dial-faster at hi speed-slow at lo speed.Flashes when the unit is is turned all the way down.The Sebo US website doesn't have the info on this machine-the UK site does-but the US one has a 12A canister motor and a 175W powernozzle motor.I have a 3.1-this "D" machine is much better.It has a 1.5Gal bag-and a pack of 8 bags came with the machine.Mike liked the machine too.Will use it for a while-and see how it goes.so far after 3 days use-like it a lot.
