The model I bought is V6 Motorhead, which I think is the most cost-effective one. It comes with 6 brush heads, which can clean beds, sofas and some small corners.
I usually use it to suck a lot of the bed, because my cat really likes to occupy my bed too much. The bed has a lot of hair and it becomes very clean after vacuuming.
The vacuum cleaner has two modes, one is normal suction, and the other is super suction.
Normal mode can be used continuously for ten to twenty minutes, while super mode is about 5 minutes. I think normal suction is enough.
The super mode I use on the bed. I bought a mite-removing bed vacuum cleaner before and found it to be useless at all.
The vacuum cleaner is also equipped with a hanger, which can be hung on the wall and charged directly, which is also very convenient for storage and does not take up space.
But the disadvantage is that you need to use a percussion drill to make holes on the wall. I didn’t hang it if it damaged the wall. However, you can also hang it with the kind of strong hook that is specially glued to the tile, that is, it can only be hung on the tiled wall.
