Why twist mop machine forming type is not good, and the formed shape is small?

There are many reasons why a twist mop machine forming type is not good. The main problem with this type of machine is that the twist mop form can get twisted and cause problems with the area being cleaned. Another issue with this type of machine is that the shape of the twist mop form is often smaller than the surface being cleaned, which can make it difficult to get deep into the cracks and crevices.

Twist mop machines are not as good as their round counterparts because they form a smaller mop head.

The round head is better since it has more surface region to get soil and residue. The twist mop machine additionally has less surface region, so it can't snatch as much soil and residue.

Twist mop machines are also less efficient because the cloth is pulled tighter by the machine.

The frame that the cloth is wrapped around also causes the cloth to be pulled tighter and this can cause fraying of the fabric.
The smaller the frame, the more likely it is that fraying will occur like floor mop machine.

The formed shape of the twist mop machines also makes them less effective because it takes longer to cover the surface area.

The twist mop machine as well as automatic sweeping and mopping machine​ also require more effort to move around the floor. The formed shape also makes it difficult to clean underneath the machine.
