RoboMower RL1000 Reviews

Friendly Robotics lawn mowers have quite a few customer reviews for the robotic lawn mower market. The majority of people gave the RoboMower RL1000 positive reviews. They found the mower to cut well, with one reviewer describing the quality of cut as excellent. They also praised the mower for being able to navigate a complicated yard. Many of the reviews were given after over a year of use, which speaks to the longevity of the product. One reviewer said they would buy this robot over and over again even if it lasted only 2-3 years. The RoboMower RL1000 costs less than he would pay for a mowing service and his lawn looks better than it would with a service as he can set the robot to mow every day if he wishes. The convenience of not having to mow himself is worth the price. Many reviewers felt the same way.

Some RoboMower RL1000 owners say they wish they had chosen a LawnBott. Interestingly, they were still satisfied with their RoboMower, but liked the smaller size, and additional features of the LawnBott and the fact that LawnBotts are quieter. However, considering the price difference, they felt the RoboMower was good value for its price. A few reviewers mentioned that the kit does not come with enough perimeter wire but that any 14 or 16g heavy wire available from home improvement stores can be used. RoboMowers use lead acid batteries which may be an issue for those who are environmentally oriented. Interested customers should also note that the slope capability is lower than for other mowers.

Overall, reviews were positive in that the RoboMower RL1000 is good value for its price tag, and has the same longevity as the current market standard. We can therefore give this robot our strong recommendation.

LawnBott Spyder Robotic Lawn Mower LB1200

The LawnBott Spyder LB1200 is designed for simplicity. It is unique among robotic mowers in that it does not require a perimeter wire to keep it in your yard. Instead, it has 12 moisture sensors which can detect live grass. When the Spyder encounters dry areas such as cement or dead grass, it stops and goes in a new direction. This eliminates the intial set up time of laying wire required for other makes and models.  There are no interactive menus, just 2 buttons, power and start/stop. The LawnBott Spyder LB1200 is ready to go out of the box. As with other LawnBott models, the Spyder features blade modulation, which monitors the amount of resistance against the blade, transferring power when it is needed. This saves battery life. Other software features include wheel sensors to prevent it from getting stuck, and safety features such as tilt sensors and handle sensors which stop the motor when touched. The LawnBott Spyder 1200‘s small size and pattern of cutting make it ideal for small yards and narrow areas such as between hedges.

LawnBott Spyder Robotic Lawn Mower LB1200 Reviews

We found a number of editorial reviews and field tests but no independent customer reviews. Field tests showed that the Spyder performed up to and beyond manufacturers specifications. The sensors worked well and, as other LawnBotts, the Spyder produced a beautiful cut. The mowing pattern of the LawnBott LB1200 Spyder is different than the other LawnBotts. Though it’s still random in nature, it turns several inches after it has reversed. The only disadvantage of the Spyder’s mowing pattern is that it is not effective for larger lawns, which of course the Spyder is not designed for. It is very quiet, which is a feature of all LawnBotts when compared to other makes.

Reviewers noted that, without a barrier, the LawnBott Spyder LB1200 will not know the difference between your lawn and your neighbor’s. If you choose this mower you will need a barrier such as bricks or stone borders, or a row of flowers surrounded in mulch in between yours and your neighbor’s lawn. . Unlike other LawnBott models, the Spyder is not fully automated so needs to be manually started and stopped, and put away to be charged in between uses. Other LawnBott models simply put themselves back to dock when they are finished. This may purely be a matter of preference but does mean that the homeowner may need to be home to put the Spyder away.

The lack of customer reviews make it difficult to recommend this product. However the lack of negative reviews lead us to believe this robot performs up to the average robotic lawn mower standard.

RoboMower RL850 Reviews

The RoboMower RL850 has the most reviews for any robotic lawn mower available. The reviews are mostly positive with 85% of owners giving the model the thumbs up. Most reviewers thought the BoboMower RL850 was very good value for the money. They compared what they would spend on a lawn service and found that even when factoring in the initial cost of the mower and its associated maintenance costs they still came out ahead. Many reviewers were enthusiastic about the savings and one reviewer noted he felt he saved about $2000.00 over 2 years. They also pointed out that their lawns looked better than if they’d hired a lawn service company as the RoboMower can cut several times a week, keeping their lawn beautifully maintained. The convenience of not having to mow themselves, gain of free time, avoidance of noise, gas fumes, heat, insects and allergies encountered when mowing were worth the cost alone. All reviewers were pleased with the cut and mulching feature, and most were impressed with how the robot handled the irregularities of their lawns. Another interesting note was from a reviewer who didn’t like to “coddle“ his lawn. He found that just setting the RoboMower at the right cutting height, the frequent mowing and mulching action helped his grass grow and crowded out the weeds over time.

We were also encouraged by the number of satisfied customer who posted positive reviews after 2 plus years.

Several reviews mention that, similar to other RoboMower packages, there is generally not enough wire or stakes included in the box to properly set up the perimeter wire. They note that you can inexpensively purchase more wire and tent pegs at home improvement stores. Of the five negative reviews, three concerned a battery charging issue that they had difficulty resolving. We noted this issue mentioned in one of the positive reviews, but in that case the issue had been quickly resolved and they felt the technical support was prompt and helpful. Of the unhappy reviewers, the issue had not been easily resolved and they felt technical support was lacking. Several people noted that the model doesn’t handle wet ground well.

Unlike other RoboMower models, the RL850 does not include a rain sensor. We aren’t sure that is a negative consideration as many reviewers happily spoke of their mower cutting in the rain. Interested customers should note that this mower is not fully automatic so will need to be driven to and from where you decide to store and charge it. This means owners may need to be home to monitor mowing. If you prefer fully automated mowing and charging we recommend you consider the RoboMower RL1000 or a LawnBott model.

Buy RoboMower RL850

In general, people said they spent about $250.00 – $300.00 per year in maintenance costs for the RoboMower RL850. This is similar to what we have found in our review of all robotic lawn mowers. Considering the number of positive reviews, we do not have any hesitation recommending this robot to owners of small to medium sized lawns.

RoboMower RM400 Reviews

We found a handful of reviews for the RoboMower RM400. In general, people seemed to be happy with its performance but found that mowing took a very long time. Although the RoboMower RM400 is marketed for those with medium sized lawns, it may be best suited to those who have small lawns. One reviewer who has a moderate sized lawns seemed to be happy once the mower had finished its initial cutting. He felt the mower was able to keep on top of his mowing needs and keep his lawn looking good all season.

One review noted that in narrow areas, less than 6’ in width, you would need to manually guide the mower with the remote control.

Buy RoboMower RM400

If you are looking for a basic robotic mower to mow a small lawn, this mower may well fit your needs. If you have a bigger yard, or have many narrow passageways you may wish to consider the RoboMower RM1000, or a LawnBott model.

LawnBott Robotic Lawn Mower LB3250

Inside the attractive red casing of the LawnBott LB3250 is a powerful robotic lawn mower for its size. It features Smart Spiral mode which activates when the LawnBott LB3250 detects a high patch of grass. This allows the mower to focus on that particular area which helps assure an evenly cut lawn. It also features adaptive programming which learns the growth pattern of your lawn over time. It then automatically modifies its mowing schedule to the actual mowing needs of your lawn. This feature saves battery life, lengthens the life of the electric motor, and contributes to a healthier looking lawn. Of course the LawnBott LB 3250 is programmable to your own preferred schedule. Like its big brother the LB3500, the LB3250 is fully automatic, and cuts in a random pattern. It comes with an alarm, safety tilt sensor and a thin, razor sharp blade which results in better cut quality than push or riding mowers.  The LB3250 also comes with a remote control. This mower is suited to medium to large sized lawns and best suits someone who doesn’t need all the bells and whistles of the LB3500.

LawnBott LB3250 Reviews

After extensive searching we found many editorial reviews but only a handful of independent consumer reviews. We did find one independent field test of the LawnBott LB3250

In field testing, the LawnBott LB3250 outperformed all manufacturer’s specifications. It handled very long grass exceptionally well. It mulched small twigs and branches with ease and its thin, flexible blade allowed it to escape damage when hitting rocks. Reports note the LB3250 is quiet especially when compared to the Robomower, mainly because of its direct motor to wheel method of action. Despite a smaller motor it is still powerful enough to handle steep slopes. Adding the spiked wheels only improved its ability to handle hills.  It has 4 programmable zones like the LB3500 but these zones are not as sophisticated as the LB3500. It is small and lightweight which helps it get into narrow and low height areas.

We found a few customers who had significant problems with battery charging when the firmware was upgraded. This happened on several occasions. Customers reported that technical support did resolve the problem but it did take a little time and investigation by the owners. One reviewer found that it seemed he was often replacing parts which became an issue after the warranty had expired. Another customer pointed out that the warranty was new again on each replaced part. The remote is not designed to drive the mower like a remote controlled car and has a range of only 20 feet.

On the positive side we found a few owners who have had the LB3250 for 3 seasons and they are still running well. One reviewer reported his LB3250 would mow for up to 8 hours with the 2 batteries installed.

Buy the LawnBott LB3250

Overall, there are few independent reviews of the LawnBott LB3250 and those reviews are mixed. However, LawnBott has a long history of quality products. If you avoid or resolve the firmware issue, it seems the LB3250 is as reliable as any of the other models, and are well loved by their owners. As there are more reviews for the LB3500 if you have a large lawn you may wish to consider upgrading to the LB3500.

LawnBott Robotic Lawn Mower LB3500

LawnBott LB3500 Reviews

In searching, we found a good number of independent customer reviews of the LawnBott LB3500. The LawnBott LB3500 is pricey compared to some other robotic lawn mowers available. Its top of the line price tag reflects a powerful machine capable of cutting large lawns with ease. People who bought the LawnBott LB 3500 did not find that the price was excessive given its capabilities. We noted that people who chose the LawnBott LB3500 were also considering a tractor or riding style mower because of the size of their yards. They ultimately chose the LawnBott LB3500 to save time, energy, money and not least of all, to eliminate the noise pollution. In addition, owners of earlier LawnBott models, tend to like the line so much that they replace their outdated mowers with newer LawnBott models. These customers reported being very happy with their upgrade to the LawnBott LB LB3500.

On the positive side, consumers liked the random mowing pattern as this helps promote grass health and a good-looking lawn. It is reported to have better stability on hills than the LawnBott Evolution and better traction than Robomower RL1000.  One reviewer stated they particularly liked the digital compass feature which prevents slippage on slopes and allows grass to be cut perfectly even on hills. They also appreciated the enhanced safety features, such as the blade stopping when the robot was lifted or the back handle was touched. LawnBotts are quiet and the LB3500 is designed to mow bigger lawns. Consumers mentioned numerous times that the battery life outperformed the manufacturer’s specifications. They were very happy with the ability of the LawnBott LB3500 to maintain a beautiful, even lawn.

As with the case of many other makes of robotic lawn mowers, a few consumers report that the LawnBotts work well for the first couple of years but then will fail for various reasons. From the reviews available, it doesn’t appear the LawnBott LB3500 fails any more often or sooner than any of the other makes currently available.
