Stone Handheld Cordless Vacuum Cleaner H7 Review

In April last year, Stone Technology launched its first own-brand handheld vacuum cleaner product H6. Also, it announced that Stone Technology officially entered the handheld vacuum cleaner market. After a year, the Stone Handheld Cordless Vacuum Cleaner H7 officially met with us. Compared with the predecessor H6, the maximum suction power of H7 has been increased to 160AW, the fast charging and dust bucket capacity have been upgraded, and it got the magnetic brush head storage.

Appearance and accessories

The packaging of the Stone Handheld Cordless Vacuum Cleaner H7 is huge, because there are a wealth of accessories such as brush heads and floor charging stands in the package. The accessories include charging stands, brushes, hoses, extension rods, aluminum tubes, floor brushes, charging stand bases, bed brushes, power adapters, etc.

Abundant accessories means that there are more abundant work scenarios, such as bed bottoms, table bottoms, sewing, etc., which can be used with brush nozzles and gap cleaning nozzles. Abundant accessories can meet the overall cleaning needs. In addition, these brush heads, extension rods and other accessories all adopt a bayonet design, which can be installed and removed in one second.

Compared with the Stone Handheld Cordless Vacuum Cleaner H6, H7’s brush head and other accessories have also added a magnetic design, which can be adsorbed on other iron surfaces, making it easier to pick and place.

For example, as shown in the image above, when cleaning the interior of the car, the brush head is easily attached to the door frame and can be removed when needed.

The floor-standing charging stand can store the host and accessories at the same time, and the host can be charged by placing it on the charging stand, and it is fully charged every time it is picked up. Of course, if you think that the floor charging stand takes up too much space, then you can also choose to use it on the wall instead.

Going back to the H7 mainframe, from the appearance design point of view, the H7 has little change compared with the previous generation H6. It is still themed in red and silver gray. The central part of the mainframe uses a transparent process to externalize the internal structure. The filter system is decorated with red, which is the finishing touch to the design and makes the product texture stronger.

Above the handle, we can see an OLED display. It can display power, wind speed, cleaning mode, working status, remaining working time, etc. When the filter needs to be cleaned, the OLED screen can intelligently remind and demonstrate maintenance methods.

In addition, long-press the lock button for 5 seconds to turn on the child lock.

Like the H6, the H7 host also adopts a detachable design, including the filter on the top of the fuselage, the cyclone component and the transparent dust cleaning bucket. It can be removed and cleaned by the switch. The filter and cyclone components can also be washed with cold water.

In terms of weight, the bare weight of the rocker handheld wireless vacuum cleaner H7 host is 1.46Kg, which is lighter than the 1.66kg of the Dyson V10. With a weight of 1.46kg, the user can hold the machine without pressure. In addition, the battery of the H7 is located under the handle. So it won’t be top-heavy when holding it.

The Stone Handheld Cordless Vacuum Cleaner H7 has a built-in DC brushless motor with a rated power of 480W, and the suction power of the whole machine is as high as 160AW. These are very high numbers in the field of handheld wireless vacuum cleaner products. Thus, we are dealing with a top-end product.

The Stone Handheld Cordless Vacuum Cleaner H7 comes with a power-type polymer lithium battery with a battery capacity of 80Wh, and the continuous current at work can reach more than 20 amperes. Compared with cylindrical lithium batteries commonly used in similar products, polymer batteries have the advantages of high endurance (experiments have proved that the energy density of polymer lithium batteries is about 25% higher than that of cylindrical batteries), long life, and light weight. For the life advantage of polymer lithium battery, Stone Technology provides a 2-year warranty including the battery.

The blessing of the polymer lithium battery brings a very significant experience improvement to the Stone Handheld Cordless Vacuum Cleaner H7. The first is long battery life, which can achieve 90 minutes battery life in energy-saving mode, 45 minutes battery life in standard mode, and 8 minutes battery life in strong mode.

In addition, the suction power will not decrease as the battery power decreases during operation. In other words, the Stone Handheld Cordless Vacuum Cleaner H7 can maintain the same suction power under different power conditions. Children know that the lower the battery, the slower the four-wheel drive will run, and the longer the running time, the slower the four-wheel drive will be. In the same way, in fact, many handheld vacuum cleaners are the same. The battery voltage will gradually decrease during the discharge process, and the suction power is far less powerful than when it is first started, and the cleaning ability is also compromised. However, the Stone Handheld Cordless Vacuum Cleaner H7 has achieved no loss of suction power. Even after working for a long time, the suction power is still the same as when it was first started.

Finally, with the “Secondary Nine Cone Cyclone”, dust is forcefully thrown into the dust bucket through strong centrifugal force. So the Stone Handheld Cordless Vacuum Cleaner H7 has also passed the TÜV Rheinland’s authoritative suction lossless certification.

Experience

In this test, we’ll try to clean the keyboard. We chose the standard working mode. Just a few seconds of working time, and the dust in the keyboard gap will be sucked into the dust bucket.

With the floor brush suction head, the Stone Handheld Cordless Vacuum Cleaner H7 can be turned into a very powerful vacuum cleaner. The floor brush suction head is equipped with a high-torque planetary gear reducer, which is suitable for most floors, floor tiles, floor mats, short-haired carpets, and is soft at the same time. The roller is free of hair and can achieve deep cleaning. In addition, the floor brush suction head can also be matched with a mopping partner (optional) to achieve mopping while vacuuming.

With the help of telescopic hoses and gap cleaning nozzles, you can also clean the environment in the car, such as the sides and bottom of the seat, the gaps in the center console, etc.

The above animation shows the dust removal scenes of sofas, seats, and flannel. Whether it is coffee powder or paper scraps, the Stone Handheld Cordless Vacuum Cleaner H7 can clean everything.

In daily life, these mites cannot be seen with the naked eye, but they are everywhere. Especially in the rainy season, when it is humid and the air is not circulated, bedding and sheets are especially prone to mites, even if you think your quilt is clean enough. When people come into contact with these items contaminated by mites, it is easy to cause dermatitis and other physical diseases, such as skin itching, hair loss, and dandruff. A large part of the cause is from mites.

For mites removal scenes such as bed sheets, pillows, and bedding, you can use the bed brush. The powerful suction can penetrate deep into the deep fibers of the mattress and effectively absorb invisible dust and dust mites on the mattress, pillow, and sofa.

As shown in the picture above, although these mites are not visible to the naked eye like hair and debris, after removing the mites, you can indeed see some gray fluffy trash in the dust box inside the H7 fuselage.

Noise and Battery Life

Of course, the Stone Handheld Cordless Vacuum Cleaner H7 will produce a certain amount of noise whether it is in energy-saving or standard and strong working mode. This is also an inevitable problem faced by any handheld wireless vacuum cleaner in the world.

We tested the noise generated in the three modes through a decibel meter. The decibel meter is located about 15cm on the upper side of the H7. In a quiet office environment (about 40 minutes), it measured 73.9, 78, and 87 minutes, respectively.

On the whole, the noise performance of the Stone Handheld Cordless Vacuum Cleaner H7 is not bad – in energy-saving mode and standard working modes, it is acceptable.

In terms of battery life, the performance of the Stone Handheld Cordless Vacuum Cleaner H7 is basically the same as that of the H6. At 100% power, we turned on the standard suction power of the H7 and continued to work for 20 minutes. The screen showed that the H7 can still work for about 25 minutes. It is estimated that this mode can work continuously for 45 minutes, which is fully in line with official data.

Compared with H6, H7’s charging speed has been significantly improved. The official said that the charging efficiency is 1.75 times that of H6, and the charging time is reduced from 4 hours to about 2.5 hours.

Conclusion

Compared with the H6, the Stone Handheld Cordless Vacuum Cleaner H7 looks much more attractive. For example, the maximum suction power has been increased from 150AW to 160AW, and the dust bucket capacity has been increased from 400ml to 500ml. A child lock and a magnetic suction brush head storage are added. Although the upgrade range is not too great, it is precisely because of these upgrades that the stone wireless handheld vacuum cleaner products have become more usable from easy to use.

All in all, the Stone Handheld Cordless Vacuum Cleaner H7 has an unconventional design, powerful configuration, complete accessories, rich functions, and a fair price. The market price of this product is 2999 yuan ($463).
