When purchasing a vacuum cleaner, a high wattage does not indicate that the vacuum cleaner is good. It only indicates the electricity it draws while being used. You should check the suction power to understand whether the vacuum cleaner is good or not. This is denoted by the term airwatt.
Battery life is an important criterion in rechargeable vertical vacuum cleaners. Most models on the market have a battery life of 2 years. After 2 years it is necessary to replace the battery, which is expensive. Some vacuum cleaner models are powered by an external battery and these batteries are easily replaceable and easily available at any time.
The second important consideration is the duration of use. Unfortunately, the lifetime of such brooms is low. In normal operation, they should be recharged within a maximum of 30 minutes. When they work in the Turbo option, the situation becomes disastrous and the red lights start to flash for 5 to 10 minutes.
