Actually my first choice was the Shark Wandvac because I like the slim form and light weight, but wasn't looking to spend $200. I found a renewed condition one on Amazon for $99: https://www.amazon.com/Shark-WS630-Ultra-Lightweight-Powerful-Cordless/dp/B0B9R93NB6/. Any experience with this?

But based on your comments it sounds like Shark is prone to breaking down and tough to get replacement parts, so not sure now.

P.S. - My primary use for this would be to just do cleaning up around my cat's litter box in my office (tile floor) because they track litter out of the box and it takes too long for the Dustbuster to pick all of it up without chalking it into the tile. So the small canister size isn't too much of an issue.
