With the average American spending some 70 hours a year dealing with lawn care, this is time that could be more fruitfully spent on more enjoyable things. The machines are coming for our jobs, so we might as well let our future robo-overlords manicure our lawns before they inevitably send us out to pasture. Without further ado, here are five of our favorite robotic lawnmowers money can buy.

The Worx Landroid is one of the more reasonably priced models on the market. It looks nice and uses the same trademark orange and black color scheme of the rest of the Worx power tool line and is able to mow up to a quarter of an acre.

This robotic lawnmower uses artificial intelligence to maneuver through narrow areas and to mow with minimal overlap. A series of sensors helps the machine avoid obstacles. You won’t be able to use the Landroid in the rain, but if the Landroid detects it, the unit will automatically return to its docking station to wait it out.

Security features include a pin number to start operation, and alerts if the Landroid leaves a designated perimeter.

We tested out the Robomow RS630 a few years ago and it’s still one of the premier robotic lawnmowers — although the price is a bit steep. However, for larger and more complex yards, you’re going to need a bit more lawnmower than the Worx Landroid.

The Robomow RS630 handles yards up to three-quarters of an acre and sloped yards up to 20 degrees, making this unit ideal for most yard types.  It also has a rain sensor to prevent mowing during inclement weather, and automatic recharging when the mower runs low on power.

With an operational decibel range of up to 78dB, the RS630 is certainly louder than the Husqvarna Automower 450X (our next recommendation), but it’s significantly quieter than your average riding lawnmower.

Husqvarna’s Automower 450X covers the most turf — up to 1.25 acres. While others models on this list incorporate softer lines and warmer, matte color schemes, the Automower 450X has more of a glossy, RoboCop 2 build and looks downright menacing in your front yard.

Like the other models, you’ll need to “fence” off the perimeter of your yard as well as garden patches before you mow (or rather it mows) for the first time. That said, you can also adjust the map of your yard via the app to mark additional zones to avoid. This is necessary for ditches or more rugged areas where the mower might struggle for adequate traction.

You can schedule the mow times over the course of a given month, allowing the model to trim as regularly or minimally as desired. Regular mowings minimize clippings, resulting in a cleaner-looking yard. But perhaps its best feature is its quiet operation.

Graded at just 58 decibels, this lawnmower is about as loud as an air conditioning unit. If you really wanted to, you probably could get away with mowing in the middle of the night without waking the neighbors.
