Before the past six months, I was convinced that the only individuals who would purchase such vacuum cleaners were those who were susceptible to the hypnosis of salespeople. Having tried almost all wireless devices in the demo halls of large stores, I came to the conclusion that I should either not buy any wireless devices at all or purchase only V8 models. This observation is true regardless of how banal it may sound. It is imperative that I state right off the bat that there are no rivals in terms of the level of cleaning provided by the dyson, as it cleans the passageway to an impeccable standard. The remaining items are all electric brooms, which catch larger particles of dirt and dust while spreading the smaller particles deeper around the space. In terms of the quality of cleaning, I am able to compare the Dyson to the Karcher SV 1902 vacuum cleaner (who is interested in my review of it). More specifically, I am able to compare the lack of even the tiniest amount of dust and the purity of the air after cleaning. There is one more solid dry-cleaning vacuum cleaner on the market in addition to the Karcher; it carries out its functions, but it also blasts dust all over the floor. When it comes to weight, the Dyson is definitely not a feather; when cleaning, you will need to go from one hand to the other, but this will not be an inconvenience. It is sufficient for 30 minutes of work in regular mode, but only approximately 10 minutes in the most powerful mode, when measured in terms of the duration of the task. There are two different ways to charge the device: one is with a wired adapter, and the other is with a stationary holder that has a wired adapter put in it. Cleaned up, hung up, and it is charging. When the charging is complete, there is no need to remove it because it automatically turns off, making it a very convenient device. In the event that the battery's capacity decreases, you are able to change it on your own. And finally, everything else being equal, you need to develop one brush that can be used for everything because switching brushes in the middle of the cleaning process is inconvenient. As a consequence of this, I was given a task, which was to complete as much local or general cleaning as quickly as possible. Utilizing this vacuum cleaner, I was able to accomplish this task in its entirety, in addition to achieving the same level of cleaning and air purification as a water vacuum cleaner. I don't work for Dyson or Karcher; rather, I aspire to become a shareholder in Gazprom.
