As the name suggests, a vacuum cleaner works simply by collecting dust and expelling air. When it is filled with dust, there is a reminder device on the machine to tell you to replace the bag or dump the dust out of the bag. The advantage of it is that it is very convenient to take out the garbage, you can directly take out the garbage bag and throw away, clean and sanitary, do not need to clean up too many times. This is a good option if you have less time.
