When it comes to housecleaning, a cordless stick vacuum is considered a jack of all trades. These devices can vacuum hard floors and carpets, sweep cobwebs from the ceiling, suck dust from drapes, and clean upholstery. With the right attachment, they can even clear up debris accumulated within long-neglected air vents.
A couple of years ago, I purchased my first robotic vacuum cleaner. While useful, this bulky device could not reach every crevice and corner within the house. These areas were expertly handled by my cordless vacuum, a Jimmy JV51.
After several years of hard use, however, the Jimmy’s battery life is beginning to fade. I chose Roborock’s new H6 cordless stick vacuum as its replacement.
The Roborock H6 Adopt arrived packed securely within a sturdy cardboard box. This kit consists of the vacuum body, powered carpet brush, powered upholstery brush, utility brush, crevice tool, flex tube, and extension tube. Also provided are a mount, AC adaptor, and a user’s guide. The Roborock H6 Soft kit is similar but comes with a softer main brush, intended for hard floors, rather than the carpet brush.
The vacuum body weighs in at 3.175 pounds. It is composed of gray plastic and fitted with a clear plastic, 400 ml dustbin. Power is provided by a 3610 mAh Lithium Polymer battery. The H6 can create up to 150 air watts of suction power.
This unit is trigger activated and can be locked on to avoid fatigue. The mode button is used to select any one of three suction levels. Critical information such as battery level, remaining time, selected mode, and maintenance alerts are displayed by a 1.3-inch OLED screen.
Also included within the vacuum body is a five-stage filtration system that removes 99.97 percent of whatever the vacuum sucks up.
The Roborock H6 ships with an easily assembled mount that accommodates both the vacuum body and all accessories. The mount—if connected to AC—may be used to charge the vacuum.

Roborock is trademarked by Beijing Rockrobo Technology Co., Ltd., which was founded in July 2014. This company specializes in the research, development, and production of robotic home cleaners. Roborock is based in Beijing, with R&D and branch offices in Shanghai and Shenzhen. Their latest product is the Roborock H6 cordless stick vacuum.
Principles of a Cyclonic Vacuum
During the 1980s, James Dyson, a British engineer, designed a vacuum cleaner that worked more efficiently than prior models, 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 with debris, many manufacturers have adopted this design.
In Roborock’s H6, 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 located within the silver-colored section of the cyclone.
Here, a similar procedure occurs, utilizing nine smaller cyclones which remove 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 the flow of air through the machine.
The air blows back into the room after passing through a second HEPA filter.
Various accessories can easily be connected to the vacuum body. To assemble for cleaning a floor, simply snap the extension pole into place and connect the carpet brush assembly.
The plastic housing for the carpet brush is ten inches in width. It can pivot from side to side as well as up and down. Two rollers and a pair of wheels ensure the brush glides smoothly across the floor.
A 50W motor turns the brush, driving carbon fiber anti-static bristles at close to 4000RPM through high-torque planetary gears. Suction power is increased automatically when a carpet is detected.
While this brush assembly is optimized for use on carpets, I found it worked very well on my wood and tile floors.
Motorized Mini Brush
This brush snaps directly onto the vacuum body. Its housing is 5.75 inches long and can pivot up and down. The quickly rotating brush works well, removing dust from upholstery.
Dust Brush and Crevice Tool
The dust brush’s long bristles are ideal for vacuuming flat surfaces, and the crevice tool is useful for tight spots such as behind a sofa’s cushions. During my tests, I used these accessories to vacuum away cobwebs growing from the corners of my living room ceiling and removing dust from curtains.
This flex tube, which can be extended to more than twice its nominal length, is used in conjunction with the dust brush or crevice tool. I found it useful when cleaning out my dirty furnace vents.
The plastic bracket holds the unit securely in place and includes mounts intended for the storage of all accessories. If placed within reach of an AC outlet, this wall mount may be used to recharge the H6 Vacuum.
A 3610 mAh Lithium Polymer battery is supplied with the Roborock H6. According to the manufacturer, this battery will maintain 85 percent of its power after 600 complete cycles.
With the dust brush attached, the countdown clock on my vacuum predicted it would function for 83 minutes in economy mode. After connecting the motorized carpet brush, the operational time dropped to 55 minutes.
In normal mode, the clock predicted an operational time of either 43 or 32 minutes, dependent upon whether an unpowered brush or the carpet brush was connected.
In high power mode, this vacuum will function for ten minutes before its battery becomes exhausted.
This vacuum worked effectively in Economy mode, picking up dirt and kitty litter without trouble. Suction increased automatically when the main brush encountered a rug or carpet.
Men, of course, don’t use Economy mode if other choices are available. I switched to medium power and briskly went about the job of vacuuming my hard floors.
I then tackled my extremely dirty sunporch. The Roborock quickly sucked up all the accumulated dirt, tiny pebbles, and dried grass. In the end, all that remained were four dried leaves, too large to be pulled around the spinning brush.
I emptied the dust bin and vacuumed my carpeted rooms and rugs. Then I pulled the grating from the furnace’s air return vent and connected the flex tube and crevice tool to my vacuum. In high power, I was able to scrape off and suck away most of the dried grit and grime that was hidden below. At this point battery level was very low.
Filter Cleaning Procedure
By the time I’d finished vacuuming the furnace vent, I was prompted to clean the filter. Usually, this is a monthly routine but, between my neglected sunporch and venting, I’d drawn far too much fine dust into the vacuum’s cyclone.
I removed the upper filter and dustbin, rinsing them both under cold tap water. Then I twisted off the cyclone and pulled away its soft high-efficiency filter.
Squeezing gently, I cleaned the soft filter with running water. Finally, I held badly clogged cyclone under the tap until all nine tubes allowed water to pass freely.
This stick vacuum is designed to compete directly with Dyson’s Cyclone V10 Absolute.
Both Roborock and Dyson have earned an excellent reputation for providing innovative and high-quality products. Each of these vacuums is extremely powerful, providing up to 150 air watts of suction.
Dyson’s vacuum is fitted with a noticeably larger dustbin and will not need to be emptied as often as the offering from Roborock. The H6, however, ships with a larger battery allowing it to operate 50 percent longer than its competition.
Stick vacuums should be as light as possible in order to avoid fatigue. The vacuum body of the Cyclone V10 is almost twice as heavy as the offering from Roborock. This, more than any other factor, should convince potential purchasers to choose the Roborock H6.
