In the search for the perfect wedding gift, I think anything that does your chores for you deserves to be high on the list. When some friends showed me their favorite wedding gift, the Robomow automatic lawn mower, I was green with envy, after having spent the better part of my Saturday battling sweltering heat and my own lawn with what was allegedly a top-of-the-line push mower.

Here's how it works: you set up a small wire around the perimeter of your lawn, which forms the fence for your mower. You set the mower down in your yard, it learns the dimensions and keeps track of its ground covered using sophisticated on board navigational technology. If there are objects in the mower's path, it simply bumps into them, then adjusts its patch around the obstacles. My friends had fun demonstrating this for me.

The mower will run unattended, taking a little bit longer than a human-powered mower in most cases, but you don't have to be there while it's running. My friends like to set theirs to mow at night. The units are resistant to rain, and even come equipped with anti-theft device, so you can set it to run in your yard and not worry about watching it cut the grass.

Not only is a robotic lawn mower a really useful gift, it can save you dozens of marital fights over who has to mow the lawn. The mowers start at around $999, and are sold at any of these locations.
