Segway Navimow Traction Wheel, Cleated Wheel, Rough Terrain Kit, Robust Wheels for Muddy Terrain and Slopes for Navimow i Series, i105N, i110N

TL; DR: Good all terrain tires, heavier, more grip for lawns that are lumpy or sloped. Should have been the standard wheels. Unless your lawn is perfectly level, and all connected, I would highly recommend these all terrain tires. They are heavier and have spikes, so the robot has more grip and can climb higher elevations. Excellent if your lawn is not perfectly level like mine. The one pain is putting on the hubcaps after you install them. They only install properly one way, after you align a small post that's on the inner side of the wheel. So you're gonna spend a good 5-10 mins trying as you blindly guess if the post is exactly where it needs to be while snapping the hubcap on.

This upgrade will help the Navimow to go up and down slope with no slipping even if the grass is wet

These wheels should really replace the syandard wheels included in the Navimow. Although advertised for very sloped yards - we noticed it has helped with our slightly uneven yard. Error reduction We have noticed significantly less stuck errors. Although our yard has a significant hill, the standard wheels handled the slope fine. The errors we were seeing was from slight ground divots or tree roots with the standard wheels. The errors went from several per mow session to once in a while. Issues With the switch, we are noticing yard where the wheels have ripped up the grass trying to get traction. Cost These wheels should be standard and not an extra cost or a different inital Navimow package so we arent stuck with the useless standard wheels.

Should have done this a long time ago. Zoysia in central Maryland. Yard is “relatively” flat with some edge areas that are sloped. This made the rows cut much more straight and these little spots that it would get stuck or struggle on an incline, fixed. I was able to move the edge back further where I had excluded it before. Battery life is better because it’s not struggling to get where it wants to go. The 10% of the problems after a year and half of use just went to 1%. I also upgraded to the aftermarket 6 blade which made a nice improvement in the quality of the cut. Couldn’t be more happy.

You spend all this money on wheels with more grip and what you get is wheels that are about 2-3 times heavier (more load on the already weak mower) and don't grip so much better as to justify the expense. What they will do, however, is spin out on problem spots and dig a nice deep rut and destroy your sod in that spot at the same time. They do grip a bit better, but the spikes need to be twice as long to really work for sloped yards or other issues that require more than the standard tire that comes with.

Big improvement on slopes and taller grass. If you don’t have these, then you might not notice a big difference. For me, it kept getting stuck on minor slopes and a little taller grass.

Avoid. Your robot will still get stuck on an 8th of an inch raised area. It will still dig massive holes in your yard. These wheels don't make it traverse any better. Save your money. If it's not working with the normal wheels, it's not going to work with these either.

These off-road wheels definitely improve the mower’s grip on rough terrain and slopes. Ease of assembly was good since the screws and wrench came with the kit. For better functionality, I bolted two sets together using extra screws to stop slipping completely, it now handles like a monster truck! Noise level didn’t change much, and for the value for money, this was worth it to keep the mower moving without getting stuck.
