Last May, I reviewed a brand-new stick vacuum designed and manufactured by Roborock. The H6 proved to be a very powerful and effective device. I was particularly impressed by the length of time it could operate before its battery required a recharge.
Today I am taking a close look at its successor, the Roborock H7.
My new Roborock H7 arrived securely packaged within a sturdy cardboard box. The vacuum body weighs in at 3.2 pounds. It is composed of gray plastic with red highlights and fitted with a clear plastic 500ml dustbin. A 3610mAh Lithium Polymer battery provides power. This 480W cyclonic vacuum can create up to 160 air watts of suction power.
The complete kit consists of the vacuum body, powered multi-surface brush, powered mini-brush, utility brush, crevice tool, flex tube, and baton. Also provided are a mount, an AC adaptor, a dust bag adaptor kit, and a user’s guide.
This trigger-activated vacuum can be locked on to avoid fatigue. A 1.3-inch OLED screen displays essential information such as battery level, remaining time, selected mode, and maintenance alerts. The mode button is used to select any one of three suction levels.
Roborock has incorporated a five-stage filtration system that removes 99.99 percent of whatever this vacuum inhales.
A magnet-based mount accommodates both the vacuum body and all of the provided accessories. The mount—if connected to the included AC adaptor—may be used to charge the vacuum.
Optional accessories for this vacuum are available from Roborock. If you are interested, you can take a look at my review of their Soft Roller Brush and Mop Set.

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.
Traditional vacuum cleaners are designed to suck in dirt and cram it into a bag. Using concepts originated by Bert Kent and Edward Yonkers, James Dyson 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.
The Roborock’s H7’s powerful motor produces suction, forcing dirt-laden air into a cylindrical dustbin and spinning it around a centrally positioned plastic cyclone.
While larger and heavier dirt particles swirl to the edge, fall downward and collect at the bottom of the bin, the slightly cleaner air is drawn through tiny holes that perforate the silver-colored section of the cyclone.
The center cone consists of nine small cyclones, which, similarly, remove most of the remaining particles of dirt.
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. The air then blows back into the room after passing through a second filter.
Roborock has provided a kit that converts this vacuum from cyclonic to a system that uses a bag to collect debris. The bag ensures a dust-free environment when emptying the vacuum bin.
To convert the H7 for use with a bag, remove the cyclone assembly and replace it with the included bracket fitted with a vacuum bag. Please note that a cyclonic vacuum is superior to one that utilizes bags. This kit should only be used by those who are allergic to dust mites.
The cleaning accessories used with the H7 vacuum are fitted with magnets which allow them to cling snugly to the sides of the included wall bracket. This bracket also accommodates the handheld unit with its baton and multi-surface brush attached.
An 80Wh, 22.2V/3610 mAh Lithium Polymer battery is supplied with the Roborock H7. It can be recharged in less than 2.5 hours using the provided AC adaptor. The adaptor may also be connected to the wall bracket.
Powered Multi-Surface Brush
The multi-surface brush is used for vacuuming floors. It usually is attached to the baton, which is then connected directly to the handheld vacuum body.
The plastic housing for the multi-surface brush is 9.75 inches in width. This brush can pivot about 45 degrees to the left or right as well as up and down. Two rollers and a pair of wheels ensure this attachment 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.
This brush typically 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 and curtains.
Dust Brush and Crevice Tool
The dust brush’s long bristles are ideal for vacuuming flat surfaces, and the crevice tool is helpful for tight spots such as behind a sofa’s cushions.
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.
Although rated for 90 minutes of operation in economy mode, the use of a powered brush reduces battery life. Operational time is also affected when vacuuming carpets. This is because the H7 automatically increases suction when its multi-surface brush detects a carpet or mat.
Economy mode is best used for vacuuming hard floors and low pile carpets.
When conducting my test of the economy mode, I connected the powered multi-surface brush and vacuumed the main floor, upstairs floor, and front porch of my medium-sized house. I was able to operate the vacuum for 55 minutes before the battery ran dry.
This mode is intended for use with hard floors and low to medium pile carpets. Suction power is significantly increased, and the vacuum was better able to handle heavier materials such as kitty litter and the small pebbles which had accumulated inside my front porch.
Operating time worked out to 35 minutes in standard mode. This would be long enough to clean an apartment or a small house.
Maximum Suction Mode
I have a very thick and dense carpet in the main bedroom. During the 9.5 minutes it took to drain the battery, the H7 pulled an incredible amount of dust, dirt, and cat hair from this floor. You really don’t know how filthy your carpets are until you tackle them with a powerful vacuum set at its maximum suction level!
The first step is to remove and inspect the upper filter. Since it represents the final phase of the H7’s dust removal system, this filter does not require frequent cleaning.
Then remove the dustbin from the handle assembly, twist off the cyclone, and pull away its soft, high-efficiency filter.
Squeezing gently, clean the soft filter with running water. Then rinse the cyclone until all nine tubes allow water to pass freely.
The final step is to wipe down the dustbin.
This vacuum is well built, powerful, and equipped with a battery that allows long periods of operation.
It comes equipped with a complete assortment of accessories, including two powered brushes and a handy flexible tube.
If you are searching for an effective cordless vacuum capable of cleaning your entire house, the Roborock H7 should be at the top of your list.
