Samuel....my local vac shop had a newer model Filter Queen come in for repairs that uses the AT1100 hose & attachments. He had remarked to me one time that he was curious & did some experimenting, & found that the Filter Queen tools will fit onto a standard Plastiflex 1 1/4" central vac hose handle (same as in the kit SBakerde sells). So, you should be fine. But WHY would you want to keep the same tools?!?! Especially the upholstery tool....have never been fond of it! Consider this the PERFECT EXCUSE to upgrade tools if you want, & custom-pick the tools you like.
