I purchased one of these for the first time about a year ago.  Although I liked it, the charge on the batteries wouldn't last long enough for me to sweep 3 throw rugs.  So when I saw this one, I noticed that it came with an extra battery so I decided to get it.  This one is sooo much better than the first one I purchased.  The first one I bought had a clear yellow cup but this one is brown.  So even though I paid the same price for both, this one is hands-down a much better product.  It almost makes me feel I got ripped off on the first purchase but I didn't know better since I had never had one before.  I definitely recommend this particular one and since they have the same name, be sure and look for the one with the extra battery and brown cup.  I wouldn't waste any money on the yellow one after seeing how good this one works.  And having the extra battery to be able to switch if needed is very helpful.
