We have purchased a variety of cordless vacuums, large, small and handheld, over the years to deal with the daily loss of cat hair and picking up dirt. This is by far the best we've ever had. Suction power - low / medium / high - use the one that suits your specific job. It even has a "Hold" button so you don't have to keep pressing the switch for it to work. Battery operated - the lower the suction power, the less battery power is used. Even in height, this is enough to optimize our 1,300 m². ft. The light weight is excellent, even lying flat and getting under furniture which larger vacuums can't, and held handles require you to tip and crawl across the floor. very surprised how much he collects every day. Works on regular carpet pile, hardwood, tile and furniture (with attachment). Easily transitions from tile/wood to carpet EXCEPT at high power when vacuuming your carpets - it can vacuum up the ends. Turn off the power and you're done. I am delighted with the wall charger. It's in and out of the garage, but it's easy to grab and quick to fix. I highly recommend this product. We've been using it for about 2 months and haven't had any problems.
