Hello fellow vacuum collecters! Well today was garage sale day in my neighborhood and something caught my eye. It was a blue Eureka Self-Propelled ESP vacuum and of course i love these types of vacuums so much i bought it for $10. I wanted to make sure it worked first before i bought so i asked the lady who sold it to me to turn it on and vacuum with it. So she vacuumed a carpet that was there and it worked fine so i bought it. I went home and vacuumed my room with it but i noticed it started to make a noise like when you vacuum up pieces of crumbs or wood or something but it made that noise for a really long time and then the motor sound got lower but I'm pretty sure i didn't vacuum anything bad up though so i turned it off. Any thoughts on why this happened?? PS: i cleaned under the vacuum removing all the dirt it it had in there and i put in a new bag. And sorry i couldn't get any pics up. My computer doesn't let me. Thanks!! :)
