Looking for an owner's manual for Hoover Bagless Twin Chamber upright vacuums with Soft Guard. Hoover produced several model numbers of this series. It was Hoover's first bagless upright model. It first came out with a 7.3 Amp motor and was later available with a 12Amp motor. Both are similar body body designs and parts and have a variety of model numbers for both motor amperages. This manual is not available on Hoover.com or this site. Many consumers are interested. Thank you very much. I have recently reconditioned two such similar machines, models: U5298-900 & U5280-940 and want manuals to give to the new owners upon sale. Thank you.
