Query: Powerful but....

It folds down neatly and pretty powerful suction. However, the seals of both water and cleanser dispensers are badly designed. They leak and leaves a pool of liquid under the machine. Everytime the water/soap tank is removed, water will drip and pool around the base of the unit. Never leave unused water or soap for it'll just drip and ruin your carpet/wood floor.
