Bidirectional mobile cleaning device

A bidirectional mobile cleaning device, comprising:

• a garbage collection box;
• a first rolling member disposed at a first end of the garbage collection box, wherein the first rolling member rotates to collect garbage on the ground and feed the garbage into the garbage collection box;
• and
• a second rolling member disposed at a second end of the garbage collection box, wherein:
• the second rolling member rotates to collect the garbage on the ground and feed the garbage into the garbage collection box,
• a direction of rotation of the second rolling member is opposite to a direction of rotation of the first rolling member, and
• a speed of rotation of the first rolling member relative to a speed of rotation of the second rolling member is controlled to control movement of the bidirectional mobile cleaning device.

A bidirectional mobile cleaning device, comprising:

• a garbage collection box;
• a first rolling member disposed at a first end of the garbage collection box, wherein the first rolling member rotates to collect sewage on the ground;
• a second rolling member disposed at a second end of the garbage collection box, wherein:
• the second rolling member rotates to collect the sewage on the ground,
• a direction of rotation of the second rolling member is opposite to a direction of rotation of the first rolling member, and
• a speed of rotation of the first rolling member relative to a speed of rotation of the second rolling member is controlled to control movement of the bidirectional mobile cleaning device;
• a first sewage recovery member adjacent to the first rolling member, wherein the first sewage recovery member is used to recover the sewage that is adsorbed on the first rolling member;
• and
• a second sewage recovery member adjacent to the second rolling member, wherein the second sewage recovery member is used to recover the sewage that is adsorbed on the second rolling member.
