I am much surprised (and delighted) to find that, (given the
same wattage) the suction power is much powerful than any
other leading brands. The initial thought of a HEPA filter
requires me to have replacement filters in the long run, but
not with this model. It is bagless and there is a button for you to push out your bigger size waste into a trash can. The finer filtration system can be cleaned and washed as often as you like or periodically depending on what size particles you work on.
The down side of this vacuum is that it comes with a limited
length or recoilable cables which needs to be plugged and unplugged from room to room.
Upon pressing the ON button of the vacuum, the "soft" start
feature is rather unique and pleasant to the ears. It makes
you anticipate the onset of compulsive dust and dirt
extraction which is about to occur.
