Spring is upon us and although we like the green stuff coming up, we would rather not have to mow it. Productivity’s LawnBott will do that unpleasant chore for you. It will run up to 4 hours or 33,000 square feet on a charge even during a light rain. The gadget will navigate up to 27º slopes or work by remote if you want to manuever it around that gigantic Elm tree in your back yard. Available in four models, owning the eco-friendly bott does not come cheaply, but for the $1,749.00 to $2,899.00 we figure it is worth the investment.
