Performance Features

Robot vacuum cleaner Explorer Serie 20 RG6871WH from the popular company Tefal is able to clean absolutely any flooring. This clever helper isn’t afraid of the graphic black-and-white palace and sun bunnies reflecting off mirrored objects. Wet cleaning option includes mopping floors, carpets and palaces.

The main disadvantage of this model, compared to other robot vacuum cleaners, is that it is not equipped with wireless connection to your smartphone. Consequently, the construction of a map of cleaning premises or control the device in real time is not possible. But users who value in household appliances ease of use, practicality and convenience will not be upset.

This smart home helper model perfectly copes with pet hair, dust, and other dirt. The active side brushes guide all small debris to the central opening, where the powerful turbo brush sucks it into the cleaner.

Tefal Smart Force Extreme robot vacuum cleaner with up to 100 minutes of run time

The Tefal Smart Force Extreme is a mid-range vacuum cleaner. For dry vacuuming. Average The manufacturer positions the model as a powerful and productive, but is it really? To look in detail at the advantages and disadvantages, as well as to help in making a purchasing decision, we have prepared a review of the device.

The characteristics

In addition to a robot vacuum, the package includes a docking station, a device for recharging, remote control, a container for liquid, spare microfiber, cleaning device and instructions. The warranty period is 12 months.

What users say

Based on our experience with the vacuum cleaner, the following conclusions can be drawn.

Operating and recharging time

Continuous work is enough for a full-fledged cleaning area of 40-70 square meters.м. Manufacturer claims 2 hours of run time.5 hours. Some users have noted in their reviews that actually cleans Tefal 6825 robot about 2 hours, after which it leaves to recharge.

The robot is charged in 5-6 hours. If during recharging the vacuum cleaner is accidentally moved from the base, it automatically returns to it again.

Overcoming obstacles

Passes bathroom and toilet thresholds well. If you can not pass with the first time, the robot persistently continues to move, as a result of the obstacle is overcome. Rides into a wool rug with no problem, gets tangled in the fringe and stops. Most obstacles are detected and passed by itself. Robotic height allows it to comfortably drive under furniture.

Quality of cleaning

The robot cleans small areas well, picks up trash from corners and baseboards. Movement is chaotic. Because of this trajectory, the vacuum cleaner may clean part of the room thoroughly and leave another room unattended and go to another room. The work session is limited in time, so in a small apartment the programmed time is enough for the vacuum cleaner to go through all the areas. For large areas, it is recommended to close the vacuum cleaner in one room. Clean more efficiently and hear less noise. Users sometimes lock the robot in each room for half an hour.

The device is relevant for rooms with pets. It picks up short and long hair well. Animal reactions to it vary. Some people do not pay attention, others are frightened.

Before you turn it on, remove all obstacles (shoes, toys, etc.), lift wires and curtains. That way, quality cleaning is improved and there is no risk of winding cables or curtains over the brushes. If the robot gets tangled in something, it beeps after a while and then shuts off.

Ideal for regular vacuuming. Users note that they limit their daily cleaning to an infrequent scrubbing of the floors. A small amount of dust on the floors is evidenced by an almost clean rag after a wet cleaning. After cleaning the carpet with a regular vacuum cleaner robot Tefal collects quite a lot of dust and debris.


Before using the infrared port for the first time, the film must be removed. Otherwise, the vacuum cleaner cannot detect obstacles.

The movement is not systematic, the robot can go 5 meters without turning, then turn around several times in one short area.

Sometimes has difficulty finding the base, especially if it is in another room. If the base is connected to the network, then the area within a radius of 1 m near it the vacuum cleaner does not clean. Does not detect dark objects. Hits walls, baseboards and black furniture, as well as chrome legs.

Capacities of the container are sufficient for 1-2 cleanings in not very dirty rooms. Collected debris and dust are presented in a compressed state. Some users claim to clean the container once every 5 days. Others recommend doing it after every cleaning, otherwise the next time you turn it on, the debris may partially fall out.

Filters and container are rinsed once a week with running water. Do not use detergent or dry accessories on heaters or in direct sunlight.

The turbo brush gets hair all over itself a lot. The brush is easy to remove from the compartment. To remove hair, they use scissors and a brush that comes with the vacuum cleaner. In one of the reviews, a user writes about how the hair got very coiled on the turbo brush shaft. The side parts melted slightly because of the friction.

There are cases when the hair is pulled between the two side brushes and winds up on them. Therefore, after each cleaning it is necessary to inspect the elements and clean them. To unscrew the side brushes a standard Phillips screwdriver is used.

Service life

The manufacturer guarantees the operation of the vacuum cleaner for two years. Among the reviews, there is a case where the motor, which drives the side brushes, broke after a year. In this case, the robot shuts down. If you replace it yourself, the part costs about 3.5 thousand. The warranty of the vacuum cleaner was 2 years, the service center offered to replace the vacuum cleaner, but the motor was not replaced.

In most cases, users are satisfied with the work of the model. Sometimes there are reviews that say that the service life is short. Sometimes the vacuum cleaner does not start after pressing the start button, but simply shuts down. In other cases, it moves in a circle and is also disconnected. Faults occur more often up to a year of use. This allows you to apply to the service center under warranty. Issues are usually resolved in favor of the consumer. Difficulties arise because of the time it takes to solve the problem. Diagnostics takes about 20 days. In cases where a manufacturing defect is found, customers can wait a long time for the necessary parts to be repaired.

Tefal Smart Force Explorer RG6825WH, RG6871WH, RG6875WH robot vacuum cleaners and their Rowenta counterparts

Another “multi-brand” review: the vacuum cleaners described are not only 100% identical from both brands, Tefal and Roventa, but also have a dozen other clones under other names around the world. Because they come from China where they can slap a label with any name on it. Despite the mass of articles, you see the same robot vacuum cleaner in different colors and equipment. with or without the bottom clip-on tank for 150 ml of water and a microfiber for wiping the floor.

  • TefalRG6825WH/RG6825WH =RowentaRR6925WH/RR6925WH. black body, no microfiber
  • TefalRG6871WH/RG6871WH =RowentaRR6871WH. dark blue top with dot pattern, with microfiber
  • TefalRG6875WH/RG6875WH =RowentaRR6875WH/RR6875WH. black body, dot pattern on top, with microfiber

Who doesn’t want to read the whole review, then briefly the gist: don’t buy this junk. It is not even worth the 10000 that they ask for it supposedly “on sale”. If you have a budget cutoff of ten grand, check out the Xiaomi G1, or better yet, study my rating in detail.

Given the way I generally feel about robot vacuum cleaners with wet cleaning, and specifically to such a primitive, which is implemented in Tefal RG6871WH/Rowenta RR6871WH and Tefal RG6875WH/Rowenta RR6875WH. that is a small water tank for 150 ml, where it arrives by gravity on a napkin. these modifications will immediately omit. Tefal RG6825WH is a cheap, basic, old Chinese robot with chaotic navigation, which Tefal branded under its name for some reason. In this respect, it has done as badly as Philips.

This is what the Tefal RG6871WH/Rowenta RR6871WH and Tefal RG6875WH/Rowenta RR6875WH microfiber looks like

Brainless chaotic with a center brush between small wheels

Yes, despite the presence of a two-color front roller on which the black and white segments alternate, contrary to the usual design in such a case under it there is no optical sensor-odometer. The gyroscope is absent too, and there is no mention of a camera or a laser rangefinder. As a result, all movements of the vacuum cleaner are completely chaotic, it has no navigation, it doesn’t make a map and doesn’t understand where it is at the moment in the room. Also, it does not remember and does not know where it has already cleaned and where it has not yet, so that the quality of cleaning depends directly on the duration of random movements over the available area, and therefore, the lack of white spots.

Despite the black and white front wheel, the Tefal RG6825WH is devoid of gyroscopic navigation

The whole series Tefal Explorer Serie 20, which includes trio RG6825WH, RG6871WH, RG6875WH, is the same pancake case with diameter of 31,5 cm and height of 8 cm. And if the length-width are relatively compact, the height is less interesting, low models are considered in the area of 7 cm or less, such as iBoto X610G. Due to the fact that Tefal (unlike similar in class Pandas and Islifs) has no “turret” on the front contact bumper, and the highest point of the top panel is shifted from the edge to the center of the body, it likes to get stuck under furniture if it manages to drive under it.

Actually, there is nothing on the top panel except one start/stop button, which sends the robot home to the charging base by double-pressing it.

On the front is a classic mechanical bumper with contact contact sensors, behind the tinted plastic are some IR proximity sensors, base search and receiving commands from the remote. I’m not so sure about the proximity sensors, by the way, because the robot crashes into objects with all its might, naturally shifting chairs. Just like Philips does, which has none.

At the bottom, in the front, there is the black and white swash plate I mentioned above. On the sides of the roller. contacts for charging. Two side-mounted side-mounted brushes with 3 beams of long, medium-hard pile at the front edges. The bristles are attached to rubber leads, they are short, but they give some additional elasticity to the construction. The brooms themselves are attached to the body with self-tapping screws. At the front and on the sides of the belly 3 infrared sensors for height difference.

The drive wheels are set back a little in relation to the main body diameter. these are two rather small 56 mm rims with only 14 mm of travel. As a result, the Tefal RG6825WH robot vacuum cleaner can only move over a threshold up to 11mm in height.

Between the drive wheels is a block with a 15 cm wide fluffy turbo-brush. At the frame-lock of the turbo brush has no jumpers, therefore, there is no protection against entanglement wires vacuum cleaner this case loves.

Idiotic little dust canister, but easy access to the battery, the former is more important

Immediately behind the turbo-brush block there is a dust canister, which is pulled out “backwards”. The dust canister is unfortunate. First of all, it is banal small. 250 ml. Secondly, it is so awkward and unintuitive to open, that it needs a separate manual:

To open the dust canister of a robotic vacuum cleaner Tefal Explorer RG6825WH does not need to press the button with an arrow (although logically you should do exactly that). You need to put your fingers in the slot through which the dust is sucked and push the top cover of the dust canister from the inside. it will open.

And if you don’t think this is dumb enough, keep in mind that opening the dust canister usually requires you to clean off the debris you’ve collected, which means you have to pick at the dust the vacuum cleaner has collected. Additional zest is added the lack of a normal instruction manual in the delivery set. it is absolutely unclear how to defeat this dust canister. This is the first time I’ve seen such an idiotic approach. Just in case there is a more informative electronic instruction.

The filter in the dust canister is a sandwich of three layers: a fine mesh screen, a foam filter and a fine paper filter (not HEPA). The last one cannot be washed, the other parts can be.

Between the front side brooms is the battery, which is easy to replace in case of failure, for this you do not even need to unscrew anything. The battery capacity is shamefully omitted by the manufacturer, but it is 2100 mAh at 14.4 V. At least the battery is not nickel-metal hydride, but Li-Ion. While the capacity is far from record, the robot vacuum cleaner Tefal Smart Force RG6825WH works on one charge really long: for the claimed 150 minutes we had it lasted about 130-135. Charging the battery on the principle of “only to send for death”. about 5 hours. Although the manufacturer exaggerated here too, promised 6. the power supply is purely toy-like in terms of current.

Unlike quite unconditioned vacuum cleaners like Redmond RV-R350, this robot has at least a charging base. I can’t say anything interesting about it, except that it finds it every once in a while. If it suddenly leaves for another room, it has almost no chance to return, just like any “chaotic”.

There are 3 modes of operation, but the essence is the same

  • Random. automatic walkthrough of the whole available space in chaotic manner until the battery is almost empty. After that, the robot searches the base by IR beam and leaves to charge, finishes cleaning. There is no way to continue the work.
  • Random Room. the same, but with a forced time limit of 30 minutes.
  • Edge. along the walls. The robot tries to move along the perimeter of the space, but if it is not a perfectly empty room with four walls, after a couple of collisions the device loses the thread and runs off into the field. All in all, a useless mode.

There is one timer, you can schedule cleaning at a certain time on a daily basis. Set with the buttons on the remote control, you must first set the current time. Both the current and cleaning time are displayed on the remote control screen. There are no other settings related to cleaning modes.

The screen shows the current time and daily cleaning time (if set), the arrow buttons can be used to control the vacuum cleaner as a radio button, the first row under the joystick 3 modes of operation. Bottom right home button

Field testing

In all tests of all vacuum cleaner robots, we left the control of power to the automation. If we didn’t have such a mode, we forced the maximum power on. In our case, the Tefal Smart Force Explorer RG6825WH 20063304 (this is its full part number) has no power options, it worked by default.

A mixture of white rice (imitation of coarse and relatively heavy debris), quartz sand (imitation of fine, pesky debris), Siberian cat hair, and women’s hair of various lengths was used as test debris (this is a classic). The initial mixture with a total weight of 100 grams was carefully gathered by the robot after each test from its dust cup, its surface, brushes and weighed on an ordinary household kitchen scale (error of measurement /- 2 grams). After that, the test room was vacuumed with an ordinary Samsung bagless vacuum cleaner, the collected debris was carefully collected from it and added to the dust collected by the robot. If something was missing from the original 100 grams, we added the appropriate debris and scattered the mixture again, for a new test.

The test room is an ordinary living room, with a total area of 31 m 2. covered with gray laminate. Obstacles were exclusively natural, a table, a couple of office chairs, a couch, a chair, a coffee table, a clothes dryer, an ironing board.

The chaotic navigation performed exactly as expected. The robot would go out into the operational space, work for about 135 minutes before it realized it needed to go to recharge, and come back. In principle, in open areas, it passed almost everywhere, and 10 times each. After more than two hours of riding, I would say there were no white spots. The lack of debris was mostly along the walls, in the corners, including near the furniture. The robot only goes into corners by luck. The 30-minute limit for white spots is a pretty good illustration that the “haotiks” are only good for beating the crap.

It should be understood that adding even a second room to the cleaning plan critically affects the final percentage of trash collected. Usually it either takes a while to clean one room, goes out into a second room, and soon dies there, or goes out into a second room relatively quickly, cleans it, and dies without going back into the first room. By eye, we would estimate the real service area at more or less acceptable efficiency to be just about 30 m 2. This is actually a typical estimate for robots with chaotic navigation.

Our estimates

Cleaning quality. Tefal Smart Force Explorer RG6825 WH collected 63% of the test garbage in more than two hours of use. This is quite an expected score. If you give the vacuum cleaner more area, the result will be worse. With an area of 31 squares, the vacuum cleaner just had enough time before the battery ran out to take its dumb route almost everywhere ten times each. In principle, you could give it a “three”, but the 30-minute mode shows more real efficiency. 2 points.

Navigation. Absolutely typical chaotic movement over the available area. Although there are attempts, but in fact along the walls does not drive, park far from always, from another room is unreal to return. 1 point.

Area, autonomous operation. The unit crawls for 130-140 minutes on a single charge of a 2100 mAh Li-Ion battery. In terms of time is okay, but without navigation, it’s still 30-40 m² maximum, and if one room. 2 points.

Obstacles, corners. Here everything is sad, the thresholds. 11 mm, carpets give or take the same amount, corners, baseboards. this is not about a line of vacuum cleaners Tefal Explorer Serie 20. It gets tangled in wires, no protection against it. All obstacles hit from the soul. 1 point.

Convenience. The dust canister is completely idiotic, when to open it you have to use your fingers to get through the collected debris and push the lid out from the inside, also of modest capacity, at 250 ml. Minus point. Turbo-brush winds hair in the way, brooms too. another minus point. At least it has a daily schedule. Howling when working God, at the level of the Viomi V2 (but that one has pluses). Being in the same room as the robot when it’s cleaning is frankly uncomfortable. which is understandable, 67dB. Another minus and the total in this discipline 2 points.

Availability of consumables, spare parts and service. This is a prime example that the official warranty and authorized service centers do not help much. Unless you get your money back in case of a breakdown. For they chronically have no spare parts and do not like to fix these Chinese electric vacuum cleaners. Private services also rarely take it, saying “this junk is unrepairable”. This is a typical situation with this kind of low quality OEM products. So paradoxically, but with an official 2-year warranty model gets only 2 points out of a possible 3.

Additional Features. There are no virtual walls in the set, it is impossible to limit the movement of the vacuum cleaner. The older versions Tefal RG6871WH/Rowenta RR6871WH and Tefal RG6875WH/Rowenta RR6875WH technically have the wet cleaning, but it does not give any bonus points in my rating, so here 0.

Review Verdict

All robot vacuum cleaners Tefal Smart Force Explorer RG6825WH, RG6871WH, RG6875WH and their analogues under the brand Rowenta. an excellent, already second after Philips Smartpro Easy, illustration of the fact that the name on the body often means nothing, and can even deceive. Tefal seems to be a famous honored French company, and released an out-of-state “OEM-China” with a double markup.

All of these creations are budget basic robots with chaotic navigation, a weak in terms of generated vacuum (and hence suction power) but loud motor, minimal walkability, a tendency to get stuck and tangled, and mediocre quality of materials and build. Service support? Well, this one The only upside is a pretty long battery life, but that’s not a reason to buy them, right??
