It depends on what you're using it for.
1. The suction of wired vacuum cleaners is relatively large. Can absorb relatively heavy weight of dirt. But it's wired. It's not that easy to use. You have to change the plug every time you change a room. And the cable is easier to wrap around and drag it back and forth.
2. The suction of cordless vacuum cleaners is relatively small. The relative weight of the suction is not so much dirt. But easy to use. Wireless use is not tied down. It can be used freely. It's not just the ground. On the wall. Roof lights are easy to clean.
If the home is more dirty and heavy, it is recommended to buy cable. Generally not very dirty some dust or hair and other simple dirty words suggest wireless?
Cordless vacuum cleaner is more convenient to use on the earth, I went to a friend's house to see that their home is using Dyson cordless vacuum cleaner, the machine is very lightweight, easy to use. So back to the home vacuum cleaner replaced Dyson cordless vacuum cleaner, the use of explosive, feeling very high-tech, suction is very big, clean up quickly. And the versatility is also quite practical, much better than my previous noisy vacuum cleaner haha.
