Hi Charles, we have several options for you. But first see if you need the adapter that will stay in the wall end of the new hose. If your inlet port hole on the wall is 1-1/4 inches in diameter then you need this adapter no matter what attachment kit you buy https://builtinvacuum.com/retail/shopretail.php?part_no=302-1.25ST
. That adapter works with all the electric kits we sell and all of them work with your Kenmore Central Vacuum System. The first three full kits listed here are all upgrades to your original equipment https://builtinvacuum.com/help/kenmore/kits.html
. The photo above them, along with the link, is for original equipment (called Hayden by us). Usually our Kenmore customers buy the Stealth Kit or BlackHawk Kit. Stealth is pricey and super high quality. BlackHawk is the least expensive but does a great job. Both have auto shutoff so the belt will not break when jammed. All the electric kits come with the wands for the electric brush and the non-electric hard floor brush (though it is not pictured in the BlackHawk photograph). If you have more questions please let us know.
