Cordless vacuum cleaners are all equipped with batteries. Currently, mainstream products use lithium batteries as the power source, which supports wireless operation and flexible movement.
Battery characteristics of cordless vacuum cleaners
Battery type:
Modern cordless vacuum cleaners generally use lithium batteries (such as polymer lithium batteries and lithium iron phosphate batteries), which have the advantages of high energy density, light weight and long cycle life.
A few early models may use nickel-metal hydride batteries, but they have been gradually eliminated.
Battery life and capacity:
Battery capacity directly affects battery life. The common range is 2200mAh to 2800mAh. High-end models can reach dual battery design (such as some models of Dreame and Mijia), with a maximum battery life of 120 minutes.
The actual battery life varies depending on the suction level. It can usually reach 60-85 minutes in low-speed mode and about 10-20 minutes in high-speed mode.
Replaceable design:
Some brands (such as Dreame and Midea) support detachable battery packs, and users can purchase spare batteries to extend the usage time.
