What to Expect from an Upright Vacuum Cleaner

-

To take or not to take, that is the question.
Is an upright vacuum worthy of attention,
Or is it necessary to resist and bypass the novelty?
Or maybe in mortal combat with a whole sea of ​​​​dust,
Will he complete the task, will he win, will he show strength?
Who, where and when invented the upright vacuum cleaner
As early as 1902, the public was in awe of Snorting Billy. This vacuum cleaner was mounted on a wagon, and its piston pump was driven by a gasoline engine. Such units were parked on the street, and while the horses were being recharged with oats, several long hoses were bred through the user’s apartments through the windows of the house.

Over time, such “devices” began to be permanently installed in hotels and large private cottages. It is said that “Snorting Billy” became the prototype of vacuum-sweeping communal machines.

Already in 1907, the first portable vacuum cleaner, convenient and affordable, was patented in the United States. It was just a vertical model , assembled “on one handle.” The revolutionary machine created the necessary airflow with the help of … a ceiling fan, in fact, mounted on an ordinary mop. The inventor of this miracle of technology, James Murray Spangler, used a pillowcase as a filter bag , and with the help of a belt drive, he made the first motorized nozzle for cleaning carpets from a conventional brush.

A year later, the famous American brand Hoover appeared, which for many years became a household name in the United States.

Over time, the power and rotation speed of the engine of upright vacuum cleaners increased several times, and technological filters appeared. It came to wireless technology and the possibility of wet cleaning. One authoritative historian of vacuum cleaners, not without humor, noted: “nothing new has been invented since then …”, “… except that they began to work worse.” But this, of course, is not the case.

Structural features
The best thing about an upright vacuum cleaner is its configuration. It is a kind of monoblock, in which all the working bodies are “linearly” located on one pipe-handle. These devices, as a rule, do not have hoses, although there are models in which it is still included (there is also a socket for connecting it), but it is used only for cleaning in hard-to-reach places.

As for the layout, manufacturers implement a variety of options, but in general, 3 types can be distinguished.

  1. The main unit with the engine, nozzle and filter is located at the forefront – all this economy is controlled by a telescopic (possibly bendable) extension handle. This is a good option for cleaning floors.
  2. The motor is in hand, the nozzle is placed on the pipe. Obviously, this option provides greater mobility, since nothing prevents the user from crawling into a tight place, and it is much easier to work with such a vacuum cleaner.
  3. Universal models that can be transformed depending on whether you need to work on weight or on the floor. A kind of 3 in 1 vacuum cleaner.

In the vast majority of cases, an upright vacuum cleaner is implemented as a “manual” device, as compact as possible. Its length varies between 1–1.2 meters (this is enough to reach the ceiling of the room even without an extension nozzle). And the width / diameter of the device varies between 12-25 centimeters, depending on how the motor is located, longitudinally or transversely. The mass of upright vacuum cleaners on average varies between 1.5–2.5 kilograms. With such a device, you can, without straining too much, vacuum in a variety of positions, especially since there are all the possibilities for this.

Interesting ergonomic features

  1. Use in a shortened version for cleaning upholstered furniture or for cleaning in a car. In fact, this function is implemented either in the form of a removable module, or simply by situational dismantling of the extension pipe.
  2. Curved pipe. This decision has two benefits. Firstly, you can vacuum under the furniture without bending down. Secondly, with Flex technologies, you can clean the top surface of cabinets without using a stool or stepladder.
  3. The LED light on the brush allows you to clean with full control even in the darkest corner.
  4. Convenient storage of the vacuum cleaner itself and accessories using the “base” (for battery models, this is also a charging dock). The base can be wall mounted or floor mounted for vertical or horizontal parking.
  5. Blocking the start key in the on state. A function from the world of construction power tools – allows you not to keep the “trigger” pressed during work and relax your hand.
  6. Easy cleaning of the container in several movements with the possibility of washing. In some models, you can shake out the garbage without even removing the dust container from the device.
  7. Digital display. It is used to control the current mode, battery status, nozzle type. Information about: imminent overflow of the dust collector, water level (for washing models), critical contamination of the filter or blockage of the motorized brush by stuck debris can also be displayed here.

Principle and suction power
Basically, manufacturers of upright vacuum cleaners now use a cyclone airflow system. For this, technologically advanced (including inverter) motors are used, which enable top models in the “Turbo” mode to develop suction power up to 150 watts. And this is already a fairly high figure, allowing the “vertical” in terms of performance to compete with conventional vacuum cleaners and perform “deep cleaning” of complex surfaces, such as carpets.

Digital control
An important feature of advanced upright vacuum cleaners is digital power control, which makes working with such devices more comfortable and more efficient, and battery consumption is more economical and predictable (including without loss of power as it discharges).

The advantage of this system is the presence of fixed power modes, which are set according to the instructions below. In addition, thanks to the use of a microcontroller, the speed of the vacuum cleaner remains stable. In addition to smooth acceleration of the engine, there is also a smooth stop. In the maximum power mode after smooth acceleration, the electronics shunts the power stage of the circuit, thereby completely removing the load from the power part of the electronics. The use of fixed digital power settings (compared to potentiometer adjustment) increases the reliability of the circuit and the accuracy of maintaining engine speed.

Operating modes
Vertical cleaners, as a rule, are equipped with several modes of operation. In addition to the basic and enhanced, there is a Turbo mode. True, when working at maximum power, the battery charge is consumed at least three times faster if the vacuum cleaner is cordless. For example, one of LG’s well-known battery models delivers 140 watts of suction power in turbo mode, 80 watts in “enhanced” mode, and about 25 watts in basic mode.

Volume and type of dust collector
Textile and paper bags are rarely used here. Plastic tanks / containers of upright vacuum cleaners have a relatively small volume, but it is easily released from the collected debris. For everyday cleaning, 0.35-0.4 liters is enough, but there are models with containers up to 0.75 liters.

How is air filtered
Purification of outgoing air in such devices is certainly not worse than in conventional vacuum cleaners. As a rule, this is a multi-stage cleaning using cyclone technology, pre-motor screens, an output HEPA filter to trap the smallest particles.

Is wet cleaning possible?
Basically, upright vacuum cleaners are designed for dry cleaning. But for hard floors there are special models that provide wet cleaning . These are compact “floor cleaners” and serious “washing systems” that are even capable of restoring carpets using DSC technology (dry cleaning).

Are cordless upright vacuums practical?
There are network-operated devices, and there are quite a few of them. But the absence of naughty wires in this case is a huge plus. And for an upright vacuum cleaner, by definition compact and ergonomic, God himself ordered to use batteries. Manufacturers put in them modern lithium-ion (li-Ion) and lithium-nickel-oxide cells (LiNiCo) with a voltage of 21.6 to 36 volts and a capacity of 1800 Ah. These batteries last more than 500 charge/discharge cycles, after which they still have about 70-80 percent capacity left. According to the Samsung developers, this should be enough for at least 5 years, since the average frequency of using the battery is about 100 charge / discharge cycles per year.

On average, most cordless upright vacuum cleaners are rated for 35-40 minutes of continuous use on a single battery. However, it must be borne in mind that in the “turbo” mode, the vacuum cleaner can operate for about 10-13 minutes. The battery reaches its full capacity on the docking station within a few hours.

To maximize runtime and minimize the chance of unforeseen downtime, manufacturers often bundle their devices with 2 batteries, giving users up to 80 minutes of continuous measured cleaning. Note also that lithium batteries allow you to charge them at any time without waiting for a full discharge.

What’s Included
The complete set of modern vertical vacuum cleaners is quite rich. For example, a rotating motorized brush is included in the basic set in many models. Also included are extension cords, crevice nozzles, soft brushes of various shapes, flexible nozzles, nozzles for hard surfaces (parquet, laminate, tiles).

Conclusions: what is an upright vacuum cleaner for?
Portable upright vacuum cleaners (especially cordless ones ) have been appreciated by consumers. They are especially warmly received by those who live in a two-level apartment or a multi-storey cottage. The resounding success of such devices has led to the formation of an entire segment of the “instant cleaning equipment” market, which is rapidly replenished with new brands and models.

If earlier they were engaged in cleaning once a week, but rather thorough, now our contemporaries prefer to do light cleaning every day, and “generalize” the dwelling – about once a month. Moreover, many users are so satisfied with the performance and practicality of vertical devices that they have completely stopped using conventional vacuum cleaners.
