    • Amazing Machine and Customer Service - App and signal was finicky for my area
Set name: Sunseeker X7
Review Image by Jackie B
Review Image by Jackie B
I will say the mower itself is fantastic. It is worth trying. It climbs slopes like a champ! The little grooves on the back combs the grass as it mows. I found that really neat and unexpected. I did have some challenges with getting a signal. It seems that it depends on the time of day for it to get a clear signal or not. I'm assuming this is due to me not mounting this on my roof. I reached out to customer service because of this and they were amazing! Best customer service I've run into in awhile and you can tell they truly care about their customers and their product. They even offered to send someone out to help get me going! Who does that these days? The app/software is a bit of a challenge. However, once you set it up, it's done. :) The good: - Super quiet - Cool looking - Makes a nice lawn tracks - Eats slopes for breakfast - Navigates obstacles well. - Amazing Customer Service. The not-so-good: -Signal drops. I didn't mount it on the roof, so perhaps that is why? I live in an HOA, so this wasn't an option for me. -The setup isn't as intuitive as I hoped. - You have to move your sprinklers daily. Not a flaw in the product, just a fact I had not considered. I have new sod and have to water daily. Again, the machine itself is nice and worth trying. I ended up returning it because of the connection & issue before Amazon's return policy ran out. I will purchase again from this company in the future based on their amazing customer service and such a promising product. I will likely need to go for their wired one due to my location and HOA and I wouldn't hesitate based on how cool this machine is. ... show more

    • Networking concerns
Set name: Sunseeker X3 Plus
Review Image by EverydayProfessional
I’m just about to bail on this mower. The mower does not seem to cut the grass as much as it beats it into submission, which is ultimately what I want, is a low grass yard. The tassles that stick up on some different grasses just get stuck around the back/idle wheels, not the powered wheels. Which is good, because it’s not sticking up. My latest issue is its “plan path failed.” This happened only after I discovered that the mower was contacting China and Hong Kong over a hundred times a day. I blocked those connections on my network system, and ever since the plan path has failed multiple times daily. It has not one time since mowed the yard in its entirety. I’m not turning the connections back on. I’m most likely going to sell this very expensive yard matting device on FB marketplace, because it’s too long out for me to return it. If you don’t mind those connections, the machine does just fine keeping the grass low, it mows approximately 0.1 acre of my yard and does fine when it actually mows. Installation was easy enough. Traction in the yard is fine, and it identifies areas where it gets stuck so you can remedy the issue at your convenience. ... show more

    • I Wanted To Like This So Much
Set name: Sunseeker X7
I live in an area of Texas where we currently have a high temp of 105-110 and yes, the grass still needs mowing, even in this heat. My yard is challenging and requires a riding mower, push mower, and weedeater to maintain. I have a steep incline for which I have to use the push mower and another for which I can only use a weedeater. My yard is not squared. I live on a curve and have features in the yard that can be a challenge to use the riding mower around. Because of all that, I really, really, REALLY wanted to like this. The PROS: It's quiet. You could use it at 3:00a and nobody would even know. It cuts great. I have a native lawn with various grasses and ground cover. It cut it all without struggling and it cut it evenly. It was able to navigate like a boss, all of the slopes, obstacles, and uneven terrain that is my yard. It's light. I can pick it up and carry it around easily. It cleans easily. The CON: Unfortunately it would not keep connection. This caused it to not be able to return to the charging station, meaning I had to go find it and carry it back every single time. I also had to remap a lot because of this and the app is so painful to use, that I just don't have the patience or time (30 day refund period) to keep trying. The satellite was mounted so that it had a clear view of the sky and the whole yard, which is only around .36 acres but it would not keep a connection. I sadly decided to send this back and maybe will try again when the product and app have improved. ... show more

    • Kept this one after returning my last mower
Set name: Sunseeker X7
Review Image by Adam
I don’t normally replace big yard equipment often, so buying a robot mower was already a big decision. The first one I purchased — a mid-range model from another brand — was such a disappointment that I ended up returning it. It got stuck constantly, struggled on my slopes, and lost signal in the same spots every week. After that experience, I honestly didn’t want to go through another setup. But the X7 has been a completely different story. What convinced me to keep it is simply that it works where the previous mower failed. My yard has two sloped sections and a few tight passages, and the X7 climbs them without hesitation. I watched it handle an off-angle slope that my last mower wouldn’t even attempt without slipping. Its ability to recover from tricky spots is also much better — no more daily rescue walks for me. The satellite navigation has been surprisingly stable too. I expected the same GPS dropouts I dealt with before, but the X7 stays locked in and maintains a consistent mowing pattern. Considering robot mowers aren’t something you buy often, I’m relieved this one actually lives up to what it promises. For the first time, I feel like I can just let it run and not think about it. ... show more

    • unable to navigate my yard
Set name: Sunseeker X7
unable to navigate my grass. It gets stuck in the deep grass and reports a navigation failure. Unable to complete any mowing job in my yard. 0 degree elevation change. This is simply a grass is too deep for the machine to handle. It triggers the front bumper as an "obstacle" that it then needs to try and navigate around and the robot just wanders for an hour before it gives up completely and I need to pick it up and take it to the base station. I cut the grass extra low to over come this limitation and the robot still can not handle 2 days growth without erroring. For a $2500 investment, this is disappointing. ... show more
