Improvements In Robotic Lawn Mowers



Robotic lawn mowers are creeping their way in​ to​ everyday American life. Like the​ dishwasher,​ they were really more trouble than they were worth in​ the​ beginning. But technological advances have made the​ robotic lawn mower practical.

Robotic lawn mowers can now mow on​ a​ time schedule and return to​ the​ charging base all season long without human intervention,​ this is​ the​ breakthrough that makes them truly useful.

An advanced feature on​ at​ least one model is​ the​ self-programmable mode. as​ these robotic lawn mowers work they determine the​ size of​ the​ yard and how fast the​ grass is​ growing,​ when they go back to​ their charging base they calculate the​ next time they need to​ come out to​ keep the​ grass at​ the​ optimal height.

Rain sensors are becoming standard equipment. When it​ starts to​ rain or​ the​ sprinkler system activates,​ they return to​ their charging base. Mowing in​ the​ rain was a​ major complaint for early adopters.

Some robotic lawn mowers even have a​ wet grass detection system. Rain sensors are a​ step in​ the​ right direction,​ but it​ is​ the​ wet grass detection system that cures the​ problem. Heavy or​ long periods of​ rain can leave the​ grass wet and the​ ground soft for days. Heavier robotic lawn mowers could get stuck and dig trenches losing traction and spinning tires. Keeping bags of​ sand handy was just considered part of​ robotic lawn mower ownership.

Light weight lithium ion batteries allow mowers to​ cut longer and recharge much faster. in​ fact some can recharge in​ as​ little as​ 4 hours allowing the​ mower to​ go out twice a​ day if​ needed.

In addition to​ faster recharge times,​ lithium ion batteries do not have the​ ‘memory’ problems associated with lead acid batteries. Basically the​ memory effect is​ caused when a​ battery is​ not fully discharged on​ a​ consistent basis,​ they remember the​ shortened life cycle,​ reducing the​ useful length of​ time until the​ need to​ recharge.

Robotic lawn mowers have become more reliable too. the​ addition of​ thermistors that detect when motors are overheating and less heat sensitive circuit boards and higher quality components extend the​ life expectancy past 10 years,​ about the​ same as​ a​ new quality riding lawn mower.

Robotic lawn mowers are now pretty much maintenance free. Changing the​ blade once a​ year and winter storage is​ about all the​ attention needed on​ a​ routine basis.

Robotic lawnmowers are now able to​ handle yards as​ small as​ 1/8 acre up to​ 5 acres. Depending on​ the​ model,​ they can handle slopes of​ up to​ 30 degrees. All major brands of​ robotic lawn mowers are waterproof and can remain outdoors all mowing season long.

Residential robotic lawn mowers require a​ perimeter wire similar to​ an​ electric dog fence to​ be laid prior to​ operating. Laying the​ wire is​ a​ one-time event that will last the​ life of​ the​ mower.

Setting the​ perimeter wire is​ probably the​ scariest part of​ purchasing a​ robotic lawn mower. it​ is​ not difficult to​ stake the​ wire in​ place. it​ usually takes about 3 hours for 1,​000 ft. of​ wire. the​ wire need not be buried as​ the​ grass and roots will grow over it​ in​ about 2-3 weeks.

If the​ mower should cross the​ wire boundary it​ will immediately stop. So there is​ no need to​ worry about it​ running away or​ mowing the​ neighbor’s yard.

Operating the​ robotic lawn mower is​ simple,​ actually easier than programming a​ VCR. in​ theory,​ programming the​ mowing schedule need only be done at​ the​ beginning of​ the​ season. the​ LCD screens have full instructions and are easy to​ read.

There are quite a​ number of​ internet sites that have detailed information about specific features of​ the​ different models of​ robotic lawn mowers. Hopefully this general description will give readers the​ interest to​ look into these new appliances.
