My Grandmom had a yellow slimline but the attachment storage caddy was inside the machine, behind the bag. Never seen one with attachment storage on the outside like that. Her slimline had terrific suction, and was quiet. I didn't even mind using it on the carpets, which is really strange for me as I'm primarily an agitator person. Mostly geared towards canisters with power head, if thats not available I take out an upright, but rare for me to just use straight suction for large areas.
