SO FAR VERY GOOD, I BOUGHT THE SHARK ALMOST A MONTH AGO AND IT HAS WORKING VERY GOOD, I HAVE TWO DOGS THAT DROP HAIR LIKE CRAZY, BUT THE VACUUM AS BEEN SAVING TIME. MY FLOOR LOOK MORE CLEANER AND WORK WITH SCHEDULE WHEN NOBODY IS IN HOME. II THINK TO GET ANOTHER ONE FOR THE SECOND FLOOR OF MY HOUSE . THANKS
