Thanks for the cat entertainment. I love watching those goofy guys ride the robots! I just got one and I like it a lot. Amazon has several brands and price points. They are returnable if it isn't for you but you do pay the return shipping. I got an inexpensive one (under $250). It does an excellent job in my sewing room with vinyl flooring. Haven't had the Bonnie Hunter problem with thread but I'm sure I don't sew nearly as much as she and I run it often. Between the cat (residual litter in paws being deposited daily) and thread I was sweeping every day before starting the sewing. Now I just turn on (no name yet) and let her run while I sew. Very nice.
