A household vacuum cleaner should have a standard rated voltage of 220V and 50Hz; otherwise, it will be difficult to connect to a shunt power supply. A reliable earthing connection is a must to prevent electric shocks caused by leakage. All joints of the vacuum cleaner should be tightly sealed: a good seal means almost no air can be felt when holding a hand close to the joints, while a poor seal is the opposite. A vacuum cleaner with poor sealing performance will not only have a weak dust collection effect but also consume more power. If the vacuum cleaner is equipped with an automatic cord rewind function, check whether the function operates flexibly and reliably.
For household use, a vacuum cleaner with a power of 400 to 600 watts is ideal, as such models are sufficient to remove dust from household carpets and other surfaces. When choosing a vacuum cleaner, first inspect its outer casing. If it has a plastic barrel, check for cracks on the barrel and ensure the connecting part between the upper and lower barrel sections is securely fastened.
If housing conditions permit, opt for a larger model as far as possible: first, it has a higher dust removal rate and relatively lower noise; second, in terms of power, a 500~800W model is generally recommended, which is mainly suitable for cleaning sofas, carpets, furniture and other items.
