My robotic vacuum automatically starts and cleans the main level of my house every day. While it does a great job, there are areas that a bulky device of this type cannot reach. And, although I could carry it upstairs to vacuum the upper floors, it is rather heavy and awkward.
I usually clean these areas with a lightweight cordless stick vacuum. Last year I replaced my broken Jimmy JV51 with a brand-new Dylon SL595 manufactured by Roomie Tec. Unfortunately, while the SL595 is a handsome machine and relatively inexpensive, its filter must be removed and cleaned at least twice every time I vacuum. If left untouched, the vacuum’s suction quickly decreases. Last month I decided to replace it with a model from Kyvol.
My new Kyvol V20 arrived with each major part securely protected by individual cardboard boxes. The package included a handheld vacuum, powered carpet brush, powered upholstery brush, utility brush, crevice tool, and extension tube. Also provided are a mount, spare HEPA filter, AC adaptor, and a user’s guide.
The main module—a handheld vacuum—weighs in at three pounds. It is composed of gray and red colored plastic and fitted with a clear plastic, 600 ml dustbin. A removeable 2500 mAh Lithium battery provides power. The V20’s 300W brushless motor provides up to 25KPa of suction power.
Included within the handheld vacuum’s body is a HEPA filter which captures 99.99% of the fine dust and microscopic particles ingested by this device.
This unit is trigger activated and, to avoid fatigue, remains on until pressed again. The mode button is used to select any one of three suction levels. A battery level indication is provided.

The Cyclonic Vacuum
During the 1980s, James Dyson, a British engineer, designed a vacuum cleaner that worked more efficiently than those which simply sucked in dirt and crammed it into a bag.
Using concepts originated by Bert Kent and Edward Yonkers, he constructed a bagless, cyclonic vacuum intended for household use. Because a cyclonic vacuum’s suction does not decrease as its dustbin fills, many manufacturers have adopted this design.
Typically, with this type of device, a powerful motor produces suction, forcing dirt-laden air into a cylindrical dustbin and spinning it around a centrally positioned plastic cyclone.
The larger dirt particles swirl to the edge, fall downward and collect at the bottom of the bin. Meanwhile, the slightly cleaner air is drawn through tiny holes perforating the metal section of the cyclone.
Here, a similar procedure occurs, with the inner cyclone removing much finer dirt particles.
The relatively clean air that results from this process passes through a HEPA filter. Since most of the dirt has already been removed, this filter only marginally impedes airflow through the machine.
Various accessories can easily be connected to this vacuum's body. To assemble for cleaning a floor, snap the extension tube into place and connect the carpet brush assembly.
The plastic housing for the powered carpet brush is ten inches in width and incorporates a set of LEDs that function as headlights. This brush performs well on both hard floors and carpets.
A quick twist of the handheld vacuum forces the carpet brush to smoothly pivot up to 90 degrees to the left or right. Two rollers and a pair of rubber wheels ensure the brush glides smoothly across the floor.
Powered Upholstery Brush
This brush typically snaps directly onto the handheld vacuum’s body but, when cleaning curtains, could be attached to the end of the extension tube. Its housing is 5.75 inches long and can pivot up and down. The quickly rotating brush works well, removing dust from upholstery and curtains.
The non-powered utility brush is a crevice tool with a brush that can be slid up and locked into place. At 3.5 inches across, this brush is wider than usual and helpful in cleaning curtains and clearing away cobwebs.
The included crevice tool is 10 inches in length and an inch across. This tool is useful when tackling tight spots such as between and behind the cushions of a couch.
The plastic bracket holds the vacuum securely and includes mounts intended for utility and crevice brush storage. Because the battery can be removed and charged wherever convenient, it is unnecessary to mount this bracket near a power outlet.
A 21.6V 2500mAh lithium battery is supplied with this unit. The power pack is removable and can be charged using the included AC adaptor.
This vacuum is equipped with a round HEPA filter. Along with the associated cyclonic components, this filter should be removed and cleaned with water each time the V20 is used.
In the real world, however, people cheat. I ran the battery dry three times before bothering to check the filter. I also allowed the level of debris in the bin to rise above the maximum level before dumping it into the trashcan. When I finally got around to checking, the filter was quite dusty, and debris had clogged many of the holes perforating the outer cyclone.
Happily, despite this abuse, the vacuum was able to maintain excellent suction pressure.
This vacuum was designed to ensure that, when fully assembled, the operator’s hands are gripping the heaviest component. This placement ensures that ceilings and drapes can be vacuumed without undue fatigue.
Each section of this vacuum snaps snugly into place. To disassemble, push the appropriate button and pull the accessory free.
The V20 worked effectively in normal power. It cleaned well and maintained suction for 41 minutes during my tests. Operational time increases when using the non-powered utility brushes. This mode is generally used when vacuuming hard-surfaced floors.
In medium power, this vacuum performed well. Its suction was strong enough to pull plenty of dust and debris from low and medium-pile carpets. When this mode is selected, the V20 can operate efficiently for 16 minutes.
The high-power setting is best used when vacuuming medium to high pile carpets. Because of the powerful suction, the operating time in this mode is limited to 11 minutes.
This vacuum is well built, versatile, and operates effectively for 40 minutes in normal power mode. When more power is required, a touch of a button results in drastically increased suction. The Kyvol V20 cordless vacuumcleaner is strongly recommended.
