My neighbor Dana has a two-story foyer with a window wall that goes up about eighteen feet. She’s been cleaning it with a swiffer taped to a broom handle for three years, and she finally snapped after watching streaks dry in the afternoon sun. She called me because I’ve been running a Winbot Mini on my shop’s storefront glass for months, and she wanted to know if the $70 jump to the Mini 2 was worth it or just marketing noise.
Fair question. I’ve used both. Here’s the honest breakdown.

The Specs That Actually Matter
| Factor | Winbot Mini | Winbot Mini 2 |
|---|---|---|
| Price | $169.99 | $239.99 |
| Footprint | Compact square body, fits between window mullions | Slightly larger, same rough footprint |
| Weight | Light enough to one-hand onto glass | Noticeably heavier, needs two hands |
| Setup time | About 3 minutes once you’ve done it twice | About 4 minutes, extra step for edge mode |
| Edge cleaning | No dedicated edge pass | Yes, dedicated edge cleaning routine |
| Cleaning modes | 3 modes | 3 modes plus edge routine |
| Safety system | 9-stage protection | 9-stage protection plus edge detection |
| Build tier | Solid plastic, feels like a $170 tool | Same plastic, better internals |
The table tells you most of it. The rest is in the details below.
Winbot Mini: The $170 Workhorse
I bought the Mini because my shop has a big storefront pane that gets pollen-bombed every spring, and I got tired of hauling out the squeegee and ladder. Setup is genuinely quick once you’ve done it a couple times. You spray the pad, stick the robot on the glass, hit the button, and walk away. It does its grid pattern, comes back to where it started, and beeps when it’s done.
The dual nozzles with ultrasonic spray are not a gimmick. It lays down a fine mist ahead of the pad instead of just dragging a damp cloth around, and that makes a real difference on dried-on grime. My storefront faces a busy road, so I get a film of exhaust residue that a plain wet rag just smears. The Mini actually lifts it.
The suction is strong. I’ve never once worried about it dropping, even on a hot afternoon when the glass is warm and the pad is getting dry. The 9-stage protection system is doing its job — I’ve watched it stop and re-grip when it hit a slightly uneven spot near the frame.
The friction: the Mini has no dedicated edge routine, and you will notice it. It gets close to the frame, but there’s always a half-inch strip of grime left behind that you have to hit by hand with a microfiber. On my storefront that’s a minor annoyance. On a floor-to-ceiling window wall, that half-inch strip is exactly the strip everyone stares at.
It’s also louder than I expected. Not deafening, but you’re not having a phone call next to it. I usually start it and go do something else.

Winbot Mini 2: What That Extra $70 Buys You
Dana ended up buying the Mini 2, and I borrowed it for a weekend to see if the upgrade was real. Short answer: yes, but only if you have the kind of glass that makes edge cleaning matter.
The Mini 2 is heavier. You feel it when you’re pressing it onto the glass, and if you’re doing a second-story window from a ladder, that extra weight is a genuine consideration. But the payoff is the edge cleaning routine. It does a dedicated pass around the perimeter before it does the interior grid, and the result is that half-inch strip is gone. Dana’s foyer window looked like a professional did it.
The edge detection is also better. On the Mini, if the robot gets near an open window frame or a screen track, it sometimes hesitates and re-routes. The Mini 2 reads the boundary more confidently and just cleans up to it.
The friction: that extra weight and the extra setup step. If you’re doing a dozen small windows around a house, the Mini 2 is more work per window than the Mini. You’re paying for capability you won’t use on a 2x3 foot bathroom window. And the price gap is real — $70 is a decent chunk of change for a tool that only does one job.
The other thing: the Mini 2’s edge routine takes longer. On a big pane that’s fine. On a small one, you’re standing there waiting for a perimeter pass that barely has a perimeter to work with.

Which One You Should Actually Buy
If you have normal-sized windows — bathroom, bedroom, kitchen, a sliding door — buy the Mini. It’s $170, it cleans well, and the edge strip it leaves behind is a thirty-second touch-up with a rag. You’re not going to care.
If you have floor-to-ceiling glass, a window wall, skylights you can reach with a pole, or anything where the edges are the first thing people see, buy the Mini 2. The edge cleaning isn’t a gimmick, it’s the whole reason the product exists at that price. Dana’s foyer window is the proof. She hasn’t touched the broom-handle swiffer since.
If you’re on the fence and the $70 matters, ask yourself one question: when you look at your worst window, is the problem in the middle or at the edges? Middle, get the Mini. Edges, get the Mini 2. That’s the whole decision.
