I was absolutely certain that such vacuum cleaners were purchased by folks who were being hypnotized by salespeople six months ago. No matter how cliché it seems, after testing practically all wireless gadgets in large stores' demo halls, I came to the conclusion that I should either refrain from purchasing anything or just purchase V8. I must state up front that the dyson cleans the passage wonderfully; there are no competitors in terms of cleaning quality. All of the other devices are electric brooms, which capture larger particles of dust and grime while scattering smaller ones over the space. I may contrast the Dyson with the Karcher SV 1902 vacuum cleaner in terms of cleaning quality, specifically the absence of even the smallest particles of dust and the cleanliness of the air after cleaning (if you're interested in my review of it). Another reliable dry-cleaning vacuum cleaner exists in addition to Karcher; it works well, but it sweeps dust onto the floor. The Dyson, which weighs in at a substantial amount, requires you to switch hands when cleaning, although this does not bother you. It is sufficient for 30 minutes of work in the standard mode and roughly 10 minutes in the most powerful. There are two ways to charge a device: either using a wired adapter or a fixed holder with a wired adapter built in. It is charged when it is cleaned up and hanging up; when the charge is complete, it switches off on its own, which is quite convenient. If the battery runs out of power, you can replace it yourself. Last but not least, you must create a single universal brush because it is inconvenient to switch them out while cleaning. As a result, I had a chore that I needed to perform as quickly as possible: cleaning. Using this vacuum cleaner, I was able to do both, receiving the same level of cleaning and air purification as a water vacuum cleaner. I want to be a stakeholder in Gazprom; I don't work for Dyson or Karcher.
