Sebo Airbelt E3 Premium vs Sebo Dart

“I posted earlier about how the Sanitaire wasn't doing its best and got a few recommendations to go for a modern bagged vacuum. After doing a bit of research I thought the Sebo E3 would do an amazing job and could consolidate my two vacuums into one (the other being an older Mighty Mite). I got it home and vacuumed my living room and felt disappointed in many ways. It's more fidley, with the light turning red and the brush turning off at different spots of my carpet. That might be user error. I had the height on 3 but played with all 4 settings. It \*really\* didn't feel like it was doing as good of a job as my waning Sanitaire. Not agitating the carpet nearly as much and the suction doesn't seem particularly high compared to the Mighty Mite. I went out and bought a belt for the Sanitaire and went over the living room again with a new belt and bag. I'm embarrassed I didn't replace the belt sooner since that seems to have made a pretty big difference. The bag had a lot of dust that wasn't picked up by the Sebo. I feel pretty bad about my purchase. I live in an apartment with a 75/25 mix of carpet and hard floor. I thought I could save space and just replace my two vacs with one. It turns out that the potential space savings aren't worth it. Were my expectations out of whack? Is something wrong with my Sebo?”

“I'm not sure. U/performancereviews would know. I bought this on a whim without demoing it, but I knew I didn't want the dart for it's lack of swiveling et1”
