The times when we swept with a broom have sunk into the distant past. However, many of us are familiar with weak vacuum cleaners, which do not make cleaning very easy. Choosing the right vacuum cleaner is not easy. What to look for when buying? We will tell you in today's article - https://kstech.com.ua/
Dust collector type in the vacuum cleaner
There are 3 types of dust collector:
Bags . The main advantage of vacuum cleaners with bags is their low price. In the future, of course, you will have to spend money on replacing consumables, but initially they are cheaper. However, changing bags is not very convenient. In addition, if you do not do this on time, bacteria will appear inside, and this is already dangerous to health. If you want to save money in the future, get a vacuum cleaner with textile bags. They can be used many times by simply washing them off from time to time.
Containers. Vacuum cleaners with containers belong to the middle price category. They are slightly more expensive than most bagged vacuum cleaners, but are easier to handle and safer for your health. They have a fairly high level of filtration. The main disadvantage of such models is the high noise level arising from the resonance of the container.
Aquafilter. Vacuum cleaners with an aquafilter are the most expensive, but at the same time the safest and most effective. They not only do an excellent job of filtering the air, but also humidify it. In order to remove the dust accumulated after the repair, you just need to pour out the dirty water from a special container. But in addition to the high price, models with an aquafilter have one more drawback - large dimensions. That is why vacuum cleaners with an aquafilter are not recommended for small apartments.
Vacuum cleaner suction power for apartment
Most often, manufacturers indicate the power on the packaging, which determines only the quality of energy consumption and the noise level. The quality of cleaning is determined by a completely different parameter - the noise level. As impressive as the power is, the main thing is that the suction power is at least 260 watts. Otherwise, the cleaning will be too shallow. If you don't have a Persian cat or Persian rugs, a vacuum cleaner with a suction power of 300 W will suffice.
Once in the hose, the air then passes through the filters and returns to the room. If the filters are of high quality, no more than 0.5% of dust gets back, this is with a filtration degree of HEPA 12 - it is the most common. If there is more dust, allergens are sprayed into the air. Such dust is more dangerous than dust in the corners. Good vacuum cleaner models are equipped with multiple filters or a HEPA filter that traps the smallest particles. But the best result is given by vacuum cleaners with a water filter - it provides air purification up to almost 100%.
Which vacuum cleaner to choose depending on the type of cleaning
Modern vacuum cleaners perform both dry and wet cleaning. Detergents perform better cleaning, but they are more expensive and larger than usual. Perhaps they are not suitable for small apartments. In any case, they will take up too much space there. But if the slightest excess of dust leads you or your loved ones to an asthma attack, it is still better to purchase a washing vacuum cleaner.
Vacuum cleaner brushes and attachments
Good brushes increase cleaning efficiency. It's good when the kit includes:
brush for smooth surfaces;
narrow crevice tool for cleaning in corners.
If there is a pet in the house, the kit should also include a turbo brush, which perfectly cleans hair and coat.
Of course, if your apartment is small, this parameter is not important. But the owners of cottages need cords from 8 m, because it is not always possible to plug the vacuum cleaner into the outlet.
Premium manufacturers have proven themselves the most on the market: Karcher, Miele, Dyson. Not bad and more affordable. For example Electrolux. If you want to save money, consider vacuum cleaners brands Scarlett, Vitek, Samsung. In any case, pay attention to the fact that the manufacturer is known. After all, you acquire equipment for more than one year, and in the event of a breakdown, it is important that there is where to go and that the parts are available.

Critical thinking is the objective analysis of facts to form a judgment. The subject is complex, and several different definitions exist, which generally include the rational, skeptical, unbiased analysis, or evaluation of factual evidence. Critical thinking is self-directed, self-disciplined, self-monitored, and self-corrective thinking. It presupposes assent to rigorous standards of excellence and mindful command of their use. It entails effective communication and problem-solving abilities as well as a commitment to overcome native egocentrism and sociocentrism.
In the term critical thinking, the word critical, (Grk. κριτικός = kritikos = "critic") derives from the word critic and implies a critique; it identifies the intellectual capacity and the means "of judging", "of judgement", "for judging", and of being "able to discern".The intellectual roots of critical thinking are as ancient as its etymology, traceable, ultimately, to the teaching practice and vision of Socrates 2,500 years ago who discovered by a method of probing questioning that people could not rationally justify their confident claims to knowledge.
The list of core critical thinking skills includes observation, interpretation, analysis, inference, evaluation, explanation, and metacognition. According to Reynolds (2011), an individual or group engaged in a strong way of critical thinking gives due consideration to establish for instance:
- Evidence through reality
- Context skills to isolate the problem from context
- Relevant criteria for making the judgment well
- Applicable methods or techniques for forming the judgment
- Applicable theoretical constructs for understanding the problem and the question at hand
In addition to possessing strong critical-thinking skills, one must be disposed to engage problems and decisions using those skills. Critical thinking employs not only logic but broad intellectual criteria such as clarity, credibility, accuracy, precision, relevance, depth, breadth, significance, and fairness.
Critical thinking calls for the ability to:
- Recognize problems, to find workable means for meeting those problems
- Understand the importance of prioritization and order of precedence in problem solving
- Gather and marshal pertinent (relevant) information
- Recognize unstated assumptions and values
- Comprehend and use language with accuracy, clarity, and discernment
- Interpret data, to appraise evidence and evaluate arguments
- Recognize the existence (or non-existence) of logical relationships between propositions
- Draw warranted conclusions and generalizations
- Put to test the conclusions and generalizations at which one arrives
- Reconstruct one's patterns of beliefs on the basis of wider experience
- Render accurate judgments about specific things and qualities in everyday life.
Total physical response (TPR)
Total physical response (TPR) is a language teaching method developed by James Asher, a professor emeritus of psychology at San José State University. It is based on the coordination of language and physical movement. In TPR, instructors give commands to students in the target language with body movements, and students respond with whole-body actions.
The method is an example of the comprehension approach to language teaching. The listening and responding (with actions) serves two purposes: It is a means of quickly recognizing meaning in the language being learned, and a means of passively learning the structure of the language itself. Grammar is not taught explicitly but can be learned from the language input. TPR is a valuable way to learn vocabulary, especially idiomatic terms, e.g., phrasal verbs.
Asher developed TPR as a result of his experiences observing young children learning their first language. He noticed that interactions between parents and children often took the form of speech from the parent followed by a physical response from the child. Asher made three hypotheses based on his observations: first, that language is learned primarily by listening; second, that language learning must engage the right hemisphere of the brain; and third, that learning language should not involve any stress.
Total physical response is often used alongside other methods and techniques. It is popular with beginners and with young learners, although it can be used with students of all levels and all age groups.
