I have the new 360i with swoop head that came with and then purchased the brush head-I love the brush head, it works really well and is worth having, however just use your best judgement on what type of carpet to us it on, you will get some resistance to the spin of the unit if used on a really heavy thick carpet, thats why i also have a 175 rotary with carpet brush, i had my 175 first then got the brush head for the 360i i find that whenever i use the 360 i almost always use the brush head now--comes in real handy if ya gotta do an apartment and go up some stairs, i'll take the 360 every time as the 175 is much heavier--hope this helps ya
