This portable vacuum actually works.  I use it in our travel trailer and it is a huge step up from the other handheld vacuums.  It's battery operated, and although each battery ( it should come with two ) only lasts about 15 minutes, that's plenty of time for me to get what I need done.  It is small and lightweight, but is actually the same height as a regular vacuum.  It also has a carpet setting with the usual roller - don't find that on handheld models.  Easy to clean the filter; can be hung on the wall ( I just stick it in a corner and charge it at home before we travel ).
