Recently? A cordless stick vacuum. My wife has wanted one because ours was too heavy and she figured she would vacuum more often if she had a lighter one. Of course that turned out to not be the case and I am still doing the vacuuming but it is a heck of a lot easier to maneuver around and bring it to other areas of the house.
Previously? Wireless ear buds. Loved those. Unfortunately my dog ate my first pair and I left the second pair on a plane. My next pair will be cheap ones.
I bought a Dyson upright ball which was an expensive purchase at the time. I thought it would cover everything needed. What a pain in the ass to use the hose and attachments.
Great if trying to reach the ceiling but tedious to use and put away. Not easy to use near the vacuum either.
I have a ryobi cordless vacuum that I found was being used more often as it was a easy pickup and vacuum on the go especially for small jobs. I bought an adapter to allow it to use the Dyson attachments so now it looks like a stick vacuum without the fuss of the Dyson ball. Game changer now I'm told.
