Although when I used it for the first time, the card was only saved from 4-5 times, the device was stupid for a long time and I was looking for a charging station because of it. The device is now very intelligent. The card will not save unless you physically charge it by touching yourself. I thought it was extremely cool that you had the option of selecting a straight suction module if there were no carpets or a turbo carpet brush. Even for the most thorough soaking of a rag, water tanks with a capacity of 240 milliliters are sufficient. The set is also happy because it has enough extra consumables to last for around one year.
