Colorado
Colorado snow comes in extremes. Denver can go weeks without a flake and then take two feet in a night when an upslope storm parks against the Front Range. Boulder averages nearly double Denver. Steamboat gets four times Boulder. And between storms the sun does half the clearing for free.
That pattern suits a robot. Zippy Snow installs a self-driving Yarbo snow blower that clears in layers through the night and recharges between passes, so an eighteen-inch storm never sits eighteen inches deep on your driveway. Dry Front Range powder is also the easiest snow a two-stage auger will ever throw.
Routes grow every season. If your town isn't listed, ask anyway — we'll tell you honestly whether we can reach you this winter.
Easterly upslope flow against the Front Range produces the big ones: 27 inches at the airport in March 2021, 20 in November 2024 with 28 in Aurora. Then a downslope Chinook arrives, January hits the 60s, and it is gone in a day. What you need at 5 a.m. is a passable driveway, not a perfect one, and the sun handles the rest.
Dry Front Range snow moves easily and throws far, up to the chute’s 40-foot limit. The exception is the spring upslope storm, which is heavy and wet, and which we plan the way we plan a Mid-Atlantic slush storm: early, tight passes before it gets deep.
The system is rated to −25 °C with onboard battery heating below that. Lithium packs do lose usable capacity in deep cold, which is why we site docks out of the wind and why the heated dock matters here. Thin air does not bother an electric drive the way it bothers a carbureted engine.
CDOT and most Front Range cities de-ice with magnesium chloride and granular Ice Slicer. Both are salts with corrosion inhibitors, kinder than they used to be but still corrosive over a season. Rinsing the tracks and greasing them is part of our service visits, and it is why the spring close-out matters.
| Where | Time to clear |
|---|---|
| Steamboat Springs | Same day |
| Denver | By the next day |
| Aurora | 24 hours |
| Boulder | 24 hours |
| Fort Collins | 24 hours |
| Colorado Springs | 24 hours |
| Golden | 24 hours |
| Grand Junction | 24 hours |
| Durango | 24 hours |
| Castle Rock | 48 hours |
Measured from when the snow stops. Colorado law also prohibits pushing or blowing snow onto a public road, with per-day fines, so apron and sidewalk throw zones always aim onto your own lawn. Nearly every Front Range city adds that the windrow the plow leaves across your driveway is yours to clear.
Same people who install and service robotic mowers for Zippy Lawnz. One crew, one app, both seasons.
Yes. Zippy West is our Colorado crew, and they install, map and service the same Yarbo systems as our east-coast crews. Map your driveway and they will tell you honestly whether they can reach you this season.
The 12-inch intake is per pass, not per storm. Storm mode sends the robot out as accumulation begins and keeps it cycling, so in a big storm it clears three or four inches at a time, docks, charges and goes back out. It never actually meets 18 inches on the pavement.
The system is rated to −25 °C with onboard heating for colder nights. Lithium batteries do give less usable capacity when cold, so runtime per charge drops and the robot simply docks more often. Altitude is a non-issue for an electric drive, unlike a carbureted gas engine.
Ask before you buy. Colorado runs a 30 percent point-of-sale discount on electric mowers, trimmers, blowers and snow blowers at participating retailers, scheduled to end on 31 December 2026 unless the legislature extends it. Whether a Yarbo snow module qualifies depends on the retailer and the state’s reading of the statute, so we would rather you confirm than assume.
It is corrosive over a season, the same as it is on your car. Tracks, augers and the underside collect it, so rinsing and greasing are part of our maintenance visits and the spring tear-down. It is not a reason to avoid a robot; it is a reason to service one.
Maybe, and we will measure rather than guess. Yarbo rates the snow configuration to a 36 percent grade, the intake raises about two inches to skim gravel, and foothills driveways under heavy trees also need a sky check for the satellite antenna. Sometimes the honest answer is that we clear the flat parts and the hill stays a plow job.
