Electrolux central vac, floor sweep malfunctioning
This is driving me nuts. The switch for the floor sweep does not turn the suction on or off...but when the vac is on in another part of the house, the floor sweep goes on (even when switch is set to off). Next, I touched the wires together and the floor sweep goes on. Could this be a wiring problem?

Often times when people bring a vac in for repairs and say it has no suction at the floor it has good suction but not good agitation. Make sure the belts in the clutch are new (some people are selling used clutches with stretched out belts) and the brush roll is good. If the agitation from the brush roll is not good it will not pick up even light soils like hair and lint.
On the Hoover U6311-900 there is no switch that turns off the suction to the tool hose. That hose is attached to the head of the vacuum on the side via a spring loaded "door". Just twist the hose to remove it, the door will close and you will have full suction again.
My Dyson dc18 had the same symptoms. The wand worked well and the floor bar had no suction. After removing pieces & shoving my fingers into the machine (no blockage) I found the suction pipe rotates between two positions (floor and wand). It looks like a piece of plastic broke on the outside housing, so it no longer rotates positions when the wheels are raised or lowered. My son found we can move the suction by sliding a finger into the mechanism behind the wheel cover, and rotating the plastic piece clock-wise or counter clock-wise until it locks into position. It's a big pain but it works for now. I wish I could find a replacement piece online. Patty
I would check the bottom of the unit to see if there is any blockage. I don't know if this unit has a switch that you set to switch from hose to floor. If so I would set it to floor and see if there is any suction in the hose, indicating a switching problem. If there is no suction in the hose, I would still check the bottom of the unit and disassemble it as much as you feel comfortable to see if you can see any blockage. Good luck!
Please define "works" on carpet mode" do you mean when you say it does not work at all, that it does not run, or does not have suction. This sounds like the symptom of a clogged hose with blockage like this another vac needs to be used to draw things back out of the hose the way they went in.. Remove the hose and try dropping a penny through it . If there is an obstruction the penny will stop at that point and rattle inside the hose.
With a blockage at the hose, your power head will still lift lint and light soft dust, it will appear to have suction because the brush will sweep but the dirt will not go all the way through the hose. Please post back to clarify if this is a vac that does not run or simpley has no suction
You either have the wrong size belt, most likely too small, or you have installed a new belt incorrectly. When you open the cover on the bottom of your vac, you will see the pulley that moves as you flip the switch from floors to carpet. The belt does not go around this pulley. When activated(carpet) the pulley puts tension on the belt causing it to turn the roller. When switched back to hard floors, the belt looses tension allowing motor to cause suction but disabling roller. Also, the dial on top of vac is only to direct suction, not for disabling roller
