I have a fairly cramped home office with large furniture and two computer , along with two full surge suppressor and a printer stand . I also have two cat and a fairly severe dust allergy . I need something light , small , maneuverable and powerful enough to get up dust and regular re-application of cat hair among all the cord and equipment . my home be a two-story new build with those annoying outlet that cut the circuit breaker if you plug anything into they that it detect as surge-y , so I be have to run my big upright vacuum cleaner from downstairs off a very long extension cord . big pain . not to mention that the big upright do not go under my desk easily . I can now use this handy little vacuum to keep my office much cleaner . I can easily get around the computer and surge suppressor , which I have up off the floor use wire shoe rack . this vacuum even fit under the printer stand , which be fairly low to the ground . be cordless , it also make vacuum the carpeted stair from the first to second floor a much , much easier job than it use to be . unlike another reviewer , I have have no problem with pet hair gunk up the beater bar . give how much I empty out of it , it seem to pick up cat hair very , very well . first time I vacuum my small office , I swear I get enough pet hair to make a third cat . the vacuum on its charger just sit next to my recycle bin and take up very little floor space .
