Partly. Window cleaning robots do a good job on glass that is cleaned regularly, but you still carry them from window to window, and they do not scrub off baked on grime. For most homes we recommend the Ecovacs Winbot W2 Pro Omni: it runs on battery or plugged in, has a safety rope and a 30 minute backup hold, and lists at $499.99 on Ecovacs' site, often less at Amazon.
Window robots clean flat, regularly maintained glass well, but a person still has to place, move and supervise them, and very dirty windows need a manual pre-clean.Ecovacs Winbot W2 Pro Omni
Best for most homes: cordless or plugged in, solid safety features and a handy carry station.
The Ecovacs Winbot W2 Pro Omni is the window robot we would buy for a typical house. It runs on a 4,500 mAh battery for about 110 minutes, or plugged into an outlet for big glass walls, and Ecovacs says it covers roughly 55 square meters per charge in Fast mode Ecovacs W2 Pro Omni ↗. That flexibility matters: you can carry it to a window with no outlet nearby and still clean. Its station is a dock, control panel, charger and carry case in one, with an automatic cord reel Ecovacs W2 Pro Omni ↗.
Safety is the first thing to check on any window robot, and this one is well covered. It has a safety rope rated to 100 kg, a backup rope at the station, a station that grips the floor with at least 800 N of suction, and a battery that keeps the robot stuck to the glass for more than 30 minutes if power drops Ecovacs W2 Pro Omni ↗. Ecovacs also offers accidental damage insurance for damage caused by loss of suction Ecovacs W2 Pro Omni ↗. It plans its route with Ecovacs' WIN-SLAM 4.0 system and has a dedicated edge mode for getting close to the frame Ecovacs W2 Pro Omni ↗.
Price swings a lot. Ecovacs lists it at $499.99, Walmart listed it at $699.99, and 9to5Toys spotted it at $399 on Amazon in April 2026 against a $700 list price Ecovacs W2 Pro Omni ↗ 9to5Toys ↗ Walmart ↗. Cybershack's hands on review gave it 87 out of 100 and found nearly streak free results on well kept windows in Thorough mode, but poor results on grimy glass, about 70 minutes of battery in Thorough mode, and a need for Ecovacs' own cleaning solution because tap water left streaks Cybershack W2 review ↗. Hands on testing is in progress; we will update this guide with results.
Why we like it
- Battery or plugged in operation
- About 110 minutes per charge
- Safety rope, backup rope and 30 minute backup hold
- Station doubles as a carry case and control panel
- Edge cleaning mode
Flaws but not dealbreakers
- Does not scrub off heavy grime
- Works best with Ecovacs cleaning solution
- Pads need frequent rinsing to avoid streaks
- Price varies widely by retailer
Ecovacs Winbot mini
Best for small windows, mirrors and shower doors, at about half the price.
The Ecovacs Winbot mini is a smaller, simpler robot for people with ordinary sized windows. Ecovacs lists it at $239.99 Ecovacs Winbot mini ↗. It works on panes as small as 22 by 25 cm (about 8.7 by 9.8 inches), so it reaches glass that larger robots cannot, including mirrors and small panes Ecovacs Winbot mini ↗. It sprays with four ultrasonic misting nozzles from a 60 ml tank and has Fast, Thorough and Spot modes, with app control over Bluetooth Ecovacs Winbot mini ↗.
It is a corded robot, with a 4.7 meter power cord, so you need an outlet nearby Ecovacs Winbot mini ↗. Its built in 3,000 mAh battery is a backup, not a power source for cleaning: if the power goes out it holds on for 30 minutes on a full charge and sounds an alarm Ecovacs Winbot mini ↗. A 3.3 meter safety rope rated to at least 1,900 N and a carabiner come in the box Ecovacs Winbot mini ↗.
Independent coverage is thinner than for our main pick. BestReviews, published by KTLA, calls it the best robot for small windows but notes that some users report noise, streaks and weak edge cleaning, and that its small pads need changing more often BestReviews ↗. Smart Robot Reviews says new US Amazon stock has been thin Smart Robot Reviews ↗. If you can find it at list price, it is the cheapest Winbot worth buying.
Why we like it
- About half the price of our main pick
- Fits panes as small as 22 by 25 cm
- Ultrasonic mist spray
- Backup battery holds it on the glass for 30 minutes
Flaws but not dealbreakers
- Corded only for cleaning
- Bluetooth app, short range
- User reports of streaks and weak edges
- Spotty US stock
Ecovacs Winbot W3 Omni
Best for homes with lots of large glass, where washing pads by hand gets old fast.
The Winbot W3 Omni fixes the most annoying chore with window robots: rinsing dirty pads. Its station washes the wiping pad in about a minute using 16 high pressure nozzles and four scrubbing discs, then drains the dirty water into a waste tank Ecovacs W3 Omni ↗. It also adds a TruEdge scrubber that lowers when the robot reaches a frame and retracts afterward, to clean right up to the edge Ecovacs W3 Omni ↗. Battery life is longer than our main pick at up to 130 minutes, and it can also run plugged in Ecovacs W3 Omni ↗.
Safety features match or beat the W2 Pro Omni: a 12 stage protection system, a main safety rope rated to 100 kg plus a backup rope, a 10 kg station that grips the floor with over 800 N of suction, and a 30 minute hold if the battery runs low Ecovacs W3 Omni ↗. Ecovacs lists it at $699.99, and Gizmodo spotted it at $566 on Amazon during a June 2026 sale Ecovacs W3 Omni ↗ Gizmodo ↗.
Cybershack rated it 4.5 out of 5 and said it cleans better and faster than doing it by hand, with good edge and corner coverage Cybershack W3 review ↗. Its complaints: the price is high for a one job robot, it leaves a faint outline where it unsticks, and it can get caught on obstacles such as roller blinds Cybershack W3 review ↗. It works best on large, square panes, and the reviewer warns that curved or cracked glass can be a safety risk Cybershack W3 review ↗.
Why we like it
- Station washes and drains the pads for you
- TruEdge edge scrubber
- Up to 130 minutes per charge
- Strong layered safety system
Flaws but not dealbreakers
- Around $700 at list price
- Big, heavy station to carry around
- Can snag on blinds and odd obstacles

Who this is for
This guide is for homeowners and renters with lots of glass: sliding doors, floor to ceiling windows, glass railings, or upper floor windows that are hard to reach from outside. It is also for small offices and shops with glass storefronts that get cleaned often.
A window robot is not a replacement for a window washer if your glass is filthy, or if you only clean windows once a year. Reviewers consistently found that these robots work best on glass that is already in decent shape, and that heavy grime needs a manual pre-clean Cybershack W2 review ↗ Cybershack W3 review ↗. If your windows are cleaned every few weeks, a robot can take over most of that work.
Why you should trust us
We have not tested these robots on our own windows yet. This guide is built from manufacturer spec pages, US retailer listings, deal trackers, and independent hands on reviews, chiefly Cybershack's reviews of the W2 Pro Omni and W3 Omni Cybershack W2 review ↗ Cybershack W3 review ↗. We also read roundups from BestReviews and Smart Robot Reviews, and note where those sites did not claim hands on testing BestReviews ↗ Smart Robot Reviews ↗.
We checked every price and spec on the source pages in October 2026 and cite each one. Hands on testing is in progress; we will update this guide with results. We choose picks on merit only.
How we picked
We started with every window robot sold in the US that appears in current roundups, then cut models we could not confirm were still in stock or that lacked basic safety gear. Safety came first, because a robot falling from an upper floor window is a real hazard. We then weighed cleaning results reported by independent reviewers, and finally price and convenience.
- Safety rope included, with a stated strength rating
- Backup battery that keeps the robot on the glass during a power cut
- Power: battery, corded, or both
- Edge cleaning and path planning
- Spray system and tank size
- Pad care: manual rinsing versus a self washing station
- Price at the maker and at major US retailers
What a window cleaning robot can and can't do today
A window robot holds itself to glass with a vacuum motor, sprays water or cleaning solution, and drags microfiber pads across the pane in planned rows. The better models detect the edges of a frameless pane and stop, and they have edge modes to clean close to the frame Ecovacs W2 Pro Omni ↗ Ecovacs W3 Omni ↗. Ecovacs says its robots can run up to 110 minutes on a charge and stay attached for more than 30 minutes if the battery runs low Ecovacs Winbot line ↗.
They do not scrub. Cybershack found hard baked dirt stayed on the glass and that very dirty windows gave poor results until they were pre-cleaned Cybershack W2 review ↗. They are also not set and forget: you place the robot on each window, remove it when it is done, and rinse or swap pads every few square meters Cybershack W2 review ↗. The W3 Omni's self washing station is the first big step toward less handling, but you still move the robot between windows Ecovacs W3 Omni ↗.
Most robots need a flat pane. Ecovacs lists minimum window sizes, and the W3 Omni needs glass at least 3 mm thick Ecovacs Winbot mini ↗ Ecovacs W3 Omni ↗. Cybershack warns that curved, irregular or cracked glass can be a safety issue Cybershack W3 review ↗. For frameless glass and outdoor use, HOBOT's SP10 adds edge leakage sensors and squeegee style scraper blades, though we could not confirm a current US price HOBOT SP10 ↗.
Before you buy
Always use the safety rope, especially on outside glass or any window above the ground floor. Tie it to a solid anchor inside, not to a curtain rod. Check that the rope rating is published: our picks list ropes rated to 100 kg or at least 1,900 N Ecovacs W2 Pro Omni ↗ Ecovacs Winbot mini ↗ Ecovacs W3 Omni ↗.
Plan for consumables. Cybershack found that the W2 Pro Omni needed Ecovacs' cleaning solution to avoid streaks and called the solution expensive Cybershack W2 review ↗. Ecovacs sells bundles with solution included Ecovacs W2 Pro Omni ↗ Ecovacs W3 Omni ↗. Budget for spare pads too, since dirty pads cause streaks.
- Measure your smallest pane against the robot's minimum size
- Check for an outlet near big windows if the robot is corded
- Wipe off heavy dirt by hand before the first run
- Do not use on cracked, curved or very thin glass
- Compare prices: the same robot can vary by $300 between retailers
What to look forward to
The biggest change is self washing stations, which started with the W3 Omni Ecovacs W3 Omni ↗. Expect that feature to move down to cheaper models over time. Ecovacs has also added edge scrubbers and moved from WIN-SLAM 4.0 to 5.0 navigation between generations Ecovacs W2 Pro Omni ↗ Ecovacs W3 Omni ↗.
A robot that moves itself from window to window is still not on the market. Until then, a window robot saves scrubbing time, not setup time. We will update this guide as new models arrive and once our own testing is done.
The competition
Ecovacs Winbot W2S OmniAround $599.99
A close sibling of our main pick with the same 110 minute battery and similar safety features, plus a 3 mm minimum glass rating and obstacle detection Ecovacs W2S Omni ↗. Ecovacs lists it at $599.99, $100 more than the W2 Pro Omni, which is not worth it for most people Ecovacs W2S Omni ↗.
Ecovacs Winbot W1 ProAround $366 at Amazon
BestReviews named it a value pick at about $366 at Amazon, but noted an app that works only over Bluetooth and user reports of inconsistent sturdiness and battery life BestReviews ↗.
HOBOT SP10 iScraperNot stated
The best option we found for frameless and outdoor glass, with 6,000 Pa suction, scraper blades, edge leakage sensors and a 230 kgf safety rope HOBOT SP10 ↗. It has only a 20 minute backup hold, and we could not confirm a US price, though Smart Robot Reviews found an Amazon listing HOBOT SP10 ↗ SRR HOBOT compared ↗.
HOBOT-2SAround $299 on sale (list $479)
A corded robot with dual ultrasonic spray that Wellbots had on sale for $299, down from $479 Wellbots ↗. Smart Robot Reviews reports limited US stock, and our main pick offers battery operation for a similar sale price SRR HOBOT compared ↗.
HOBOT 298Around $199 on sale (list $359)
An older HOBOT on sale at Wellbots for $199 Wellbots ↗. Smart Robot Reviews calls it a legacy model SRR HOBOT compared ↗, and we would rather spend a little more on the Winbot mini.
HUTT S55 ProNot stated
Smart Robot Reviews lists it as a standalone value pick with SLAM 4.0 navigation and an 80 ml tank Smart Robot Reviews ↗. We could not confirm a US price or safety ratings from the maker.
Tosima W5$404.49 at reseller Under Yours (regular $546.49); Amazon price not stated
BestReviews praises its triple safety system and dual direction spray, but it lists no price and notes the pads can leave lint behind BestReviews ↗.
Questions people ask
Do window cleaning robots actually work?
Yes, on glass that is already in fair shape. Cybershack found the W2 Pro Omni left largely streak free glass on well kept windows, but poor results on grimy windows until they were cleaned by hand first Cybershack W2 review ↗.
Are window cleaning robots safe on upper floor windows?
They are designed for it, but use the safety rope every time. Our picks include ropes rated to 100 kg or at least 1,900 N, and backup batteries that keep them stuck to the glass for 30 minutes or more during a power cut Ecovacs W2 Pro Omni ↗ Ecovacs Winbot mini ↗ Ecovacs W3 Omni ↗.
Can a window robot clean both sides of the glass at once?
No. Current robots clean one side at a time. You attach it inside, then outside, using the safety rope for the outside pass Ecovacs W2 Pro Omni ↗ Ecovacs W3 Omni ↗.
Do window cleaning robots work on frameless glass?
Many do. The Winbot W2 Pro Omni says it works on all types of flat windows, and the HOBOT SP10 has sensors built to detect gaps in frameless panels Ecovacs W2 Pro Omni ↗ HOBOT SP10 ↗.
How long does a window robot take?
Cybershack measured about 2.5 minutes per square meter in Fast mode and 6 minutes in Thorough mode on the W2 Pro Omni Cybershack W2 review ↗. A large patio door takes a few minutes, but you still move the robot between windows yourself.
Do I need special cleaning solution?
Ecovacs recommends its own solution, and Cybershack found tap water left streaks on the W2 Pro Omni Cybershack W2 review ↗. Distilled water may help, but plan on buying the maker's solution.
How much does a window cleaning robot cost?
Ecovacs' Winbot line runs from $239.99 for the mini to $699.99 for the W3 Omni at list price Ecovacs Winbot mini ↗ Ecovacs W3 Omni ↗. Sales are common: the W2 Pro Omni has sold for $399 on Amazon 9to5Toys ↗.
