I've had my little Robbie for a few months and this is an updated review. I love it! Every other day I turn it loose in my bedroom and sometimes almost forget about it. It has never gotten stuck under any furniture but I do take precautions to block certain areas. It runs smoothly over my ww carpet, onto rugs, and onto vinyl floor. There is an area next to commode that it gets stuck so I block that area. It does a really good job and the dust cup is filled with hair, lint, dirt, and dust. It is truly remarkable how much it collects. It took awhile to grow on me but now I don't know how I ever lived without it. Wal-Mart has an excellent price but I wish it were more around the $150 mark. If it were I would by two for my daughters-in-law for Christmas. I got mine as a Sparks reviewer. Love it.
