Anyone who has cats (or children) knows why they need it. Lots of different cat toys, bouncy balls, etc. under my stovetop. I suspect the other reviewers got a different or older product/iteration as my attachment fits the Dyson V6 well. The suction power is okay. My only complaint is that the tool looks longer than mine in the photos. That being said, this tool was MUCH better for gouging than the Dyson gouging tool, the typical retractable gouging tool you can find at Revain. This one tapers towards the end, giving you extra inches. However, the length is not long enough for my needs. I bought two brands this week and still can't find anything that gets far enough under the oven or cabinets or between the stove/fridge etc. This product is the best I've found so far. still searching They need something about 1 foot longer with a continuous taper at the end. You may need to start a business and start it yourself!
