Maryland
Maryland is three winters in one state. Salisbury averages 8 inches of snow a year, Baltimore about 19, and Oakland in Garrett County more than 100. What they share is the part that hurts: the snow is wet, it lands near freezing, and it usually arrives on a weekday morning with a three-hour sidewalk deadline attached.
Zippy Snow puts a self-driving Yarbo snow blower on your property and runs it for you. It clears in thin layers while the storm is still falling, so the heavy stuff never gets deep, and you never go out in it. We are the winter arm of Zippy Lawnz, and our home crew is on the Eastern Shore in Easton.
Routes grow every season. If your town isn't listed, ask anyway — we'll tell you honestly whether we can reach you this winter.
The National Weather Service puts the rain-versus-snow line over or near the I-95 corridor in most storms. That is why Frederick and Carroll get more than Baltimore, why the Shore usually gets rain, and why forecasts bust so often here. A robot that starts when the snow starts does not care what the forecast said at bedtime.
Maryland snow is dense and water-laden, the kind that makes a shovel feel like it is full of wet sand. We plan for it with early, tight passes so the robot only ever meets two inches of slush instead of eight.
Baltimore City and Annapolis both give you three hours after the snow stops. That is a hard deadline to hit before work with a shovel. It is not a deadline at all if your walk was cleared at 2 a.m.
The State Highway Administration pre-treats with brine, which turns light snow into salty slush and leaves an apron berm that refreezes hard. We map the apron as its own zone and time a pass for after the plow goes by.

Measured from when the snow stops. Most of these also prohibit throwing snow into the street, which is a mapping rule for us. Check your own municipality before relying on any of it.
Same people who install and service robotic mowers for Zippy Lawnz. One crew, one app, both seasons.
Yes. Our Delmarva crew is based in Easton and covers the Eastern Shore, with routes reaching across the Bay to the Baltimore, Annapolis and Washington suburbs. Map your driveway and we will tell you honestly whether we can reach you this season.
Yes, provided it starts early. Wet snow is the hardest thing to ask of any snow blower, so we do not let it get deep: the robot clears in layers while the storm falls rather than attacking eight inches of slush afterwards. For rain that freezes to the pavement, de-icing is still a human job.
Almost certainly, because it does not wait for the storm to end. Baltimore City and Annapolis give you three hours after snowfall stops. A robot that has been cycling since midnight has the walk clear before the clock even starts.
Every Maryland county says that pile is yours to clear. We map the apron as its own zone and schedule a pass after the plow’s usual window, so the robot meets loose snow instead of a frozen wall. If it has already refrozen solid, that is a service call, not your problem.
The Yarbo hardware is $4,999 for snow only, or $7,199 for the mow-and-snow combination at list price. Installation depends on your site, and there is a fully managed plan if you would rather not own the machine. Your local crew quotes the whole number after a site visit.
Sometimes. The intake raises about two inches to skim above the stone, and compacted, well-crowned gravel usually works. Loose, deep stone usually does not. Yarbo’s own guidance is paved surfaces, so we give you a straight answer at the site assessment rather than after you have paid.
