I use cordless robots more often because I work in the cordless robot industry.Thank you Michael! That's very helpful. You say you don't have too many wired robots. Should I consider a wireless one? I was assuming the wired robots would last longer because they don't have batteries and it seems like rechargeable batteries eventually decline (like on my power tools). But I guess I could replace the battery if necessary...?
In terms of the skimmer, do you think it would clean leaves off my negative edge? This is where a lot of my leaves collect, right at the drop off of the ledge. It would need to climb onto the negative edge ledge (~1 ft wide and water going from 0 to ~1 inch deep).
Cordless robots have indeed developed very well in the past two years due to their convenience.
But it has not yet reached a mature and stable stage.
You're right, currently cordless robots are unable to overcome the issue of lifespan. Its rechargeable battery will eventually fail. Because pool robots are too easily damaged by water they come into contact with.
And the battery cannot be replaced. They are wrapped in layers of waterproof measures, and even if you open and replace them, you cannot achieve 100% restoration of their waterproof performance.
And in many cases, battery failure is just one of the manifestations of its damage. In fact, the circuit board or motor has been exposed to water, causing a short circuit and rusting, and burning out. The battery accelerates the process from short circuit to damage.
Even if you replace the battery, it will quickly be damaged again.
At present, beatbot has done a good job in terms of sealing design, but it start sell for only 1 year, cannot fully prove its durability.
If you value long-term use the most, then you can purchase Dolphin.
They have enough experience to produce better quality and more durable products.
Regular maintenance of the track and other components is sufficient.
Regarding the Skimmer.
You may not be able to use it, I guess. It cannot know its location through ultrasonic sonar in an environment without walls as edges.
You can send pictures of your pool or try asking BETTA customer service if it can be used, or try it out while keeping the original packaging intact and not affecting secondary sales.
If it's not working well, just wipe the machine clean and return it.
But if you can use it, you will definitely love it very much.
