to keep my floor food free -lrb- no crumb for the mouse -rrb- I use this stick vac -lrb- psv1800 -rrb- . its great for small job do between my weekly vacuuming . where do I use it ? on carpeting , hard floor and furniture . at first it be great on all surface , but after a few month its do better on carpeting than hard floor . I try to vacuum my small car with it , but its length make that awkward . although it fold , the fold be in the wrong direction to make it short enough to use in the car . << Edit Nov 2009 I take it apart recently when it stop pick up altogether . I find that the filter be completely clog . after I clean off the dust -lrb- the filter be re-usable -rrb- it work a good as new ! so I recommend clean the filter every couple of month . >> i use it mostly in the kitchen , dining room and living room . I also use it in my entry way too to prevent dirt from be track all over the house . how 's the battery life ? supposedly it will last 20 minute . but I have not run it for more than 5 minute at a stretch , so the battery have not die on I yet . be it easy to use ? yes , just unfold it and hit the on switch . however , it do require a little strength . it weigh only 5 pound , but concentrate along a stick that could feel heavy . its a little lighter than a gallon of milk -lrb- 8 pound -rrb- . empty the dust , crumb and dirt be a cinch . its bagless , so you open a compartment and everything will fall out . I have not have to reach in and scrape out dust yet . con the price keep this vacuum from earn 5 star . I do not think its worth $ 100 .
