I am always vacuuming...I have 7 cats in the house and one big dog...it is heavy and does not have room for all the tools on board...this unit has to be taken apart EVERY time I am done vacuuming because of all the hair and I want it to work efficiently every time I vacuum so I always keep it clean...so it works as good as the first day out of the box. I would not buy this unit again, it is to heavy and is to hard to keep clean.
