How do I disassemble a suction blower connector from the hose on a sweeper?

Reattach the hose to the base unit. This is most common issue with ours. Then do the same with the wand to hose connection. Has it come loose by chance? Ours does not have a reset on the power sweeper but some may. Look for a reset switch and press it in.

your hose is blocked get some thing long and thin push it done the hose and try and clear it

The hose is clogged up. Try disconnecting the hose and loosen the clog. If you try to pick up pine needles, they are sticky and will clog up any vacuum sweeper.

You probably have a broken belt on the beater bar (sweeper) or a string/rope caught in into to cause it not to turn. Last option if it is a cannister type, that the electrical connection in the hose are not connected to the beater-bar unit well.

If suction is bad, you may have a full bag (replace with a fresh one). Alternatively, you may have a clog somewhere along the hose or just inside the unit.

this is caused by a dirty air filter and/or a blocked vacume hose ( most of the time the blockage is at the bend where the hose enters the floor sweeper area ) ---
remove and tap out and brush the filter ( or use a air compressor to blow out filter ).
then with the vacume on its side - remove the bottom plate ( like you were going to change the belt ) and use a coat hanger and clean out the hose between the floor sweeper and where the suction hoes attaches. this will restore your vacume to full operation.

Yes you can. The end of the hose that mates with the suction/blower is flexible. You can use a pair of needle nose pliers to compress the hose end and force it out of the suction/blower connector.

Your hose has a restriction. To fix this, use a broom handle and insert it into the hose as far as it will go. If the hose can be removed, take it off completely and do this, if not be careful so as to not damage the sweeper with the handle. another way to fix this is to blow compressed air through it (this is good to do to all vacs to keep them working good) You can get the compressed air from an air compresser or a shop vac or even a leaf blower, but that will take two people. Once you clear the blockage the sweeper will work fine again. best wishes!

I like using a Wire Clothes hanger to work the stuff out with. If you fashion a fish hook of sorts out of the wire, you can catch things inside the brush head and pull them out.
