i have it, personally i will not bother to use it daily. Once aweek still ok coz it is very bulky & troublesome ...
The suction is really very GOOD, even after you just sweep & mopped the floor, with Rainbow, you can still vacumm lots of dust & hairs
can use it to clean the room air ie let the vacumm run for few minutes with the room closed up. You can feel the difference in air
can also use to clean the mattress & cushions, you will find out how dirty the matress is !!!
for me, i oni use 2-3 times a week, clean air once a week & mattress so far oni done twice after having it for about a yr
