The Shark Messmaster is the perfect vacuum for even the toughest job. This vacuum is smaller than the average portable vacuum. Its shape makes it easy to store, even in smaller spots. The size does not affect power. I’m the suction power is as great as any larger vacuum. Great for a car cleaning job, and was absolutely perfect for our camper. Stored easily in the closet. It has attachments for every type of job, wet or dry.
