The Ecovacs Winbot W2 Pro Omni is the window cleaning robot we would pick for most homes. It runs on battery for about 110 minutes or plugged in, has solid safety backups and a station that doubles as a carry case. It is worth it for windows you clean regularly, especially on sale, but it will not scrub off heavy grime.
What Ecovacs Winbot W2 Pro Omni is
The Winbot W2 Pro Omni is a robot that sticks to a window with suction, sprays cleaning solution and wipes the glass with microfiber pads in planned rows. It works on framed and frameless flat glass with a minimum size of 30 by 40 cm and glass at least 3 mm thick Ecovacs W2 Pro Omni ↗.
It comes with a station that acts as a dock, charger, control panel and carry case, with an automatic cord reel and a handle Ecovacs W2 Pro Omni ↗. The robot itself weighs about 1.6 kg and the station about 5.5 kg Ecovacs W2 Pro Omni ↗. In the box you get the robot, station, safety rope, carabiner, two wiping pads and an empty solution bottle Ecovacs W2 Pro Omni ↗.
Hands on testing is in progress, and we will update this review with results.
What it does well
It works with or without an outlet. The 4,500 mAh battery runs about 110 minutes per charge and recharges in up to 3 hours Ecovacs W2 Pro Omni ↗. Ecovacs says that covers about 55 square meters in Fast mode or 22 in Deep mode Ecovacs W2 Pro Omni ↗. For big glass walls you can plug it in instead, with a 5.5 m power cord Ecovacs W2 Pro Omni ↗.
Safety is well covered. It has a safety rope plus a backup rope at the station, and the station grips the floor with at least 800 N of suction Ecovacs W2 Pro Omni ↗. Ecovacs says the battery keeps the robot stuck to the glass for more than 30 minutes if power drops, and it offers accidental damage insurance for damage caused by loss of suction Ecovacs W2 Pro Omni ↗ Ecovacs Winbot line ↗.
It cleans methodically. It plans its route with Ecovacs' WIN-SLAM 4.0 system and has a dedicated edge mode, which Ecovacs says improves edge cleaning by 65 percent Ecovacs W2 Pro Omni ↗. Fast mode cleans a 1 by 1 meter area in about 1 minute 45 seconds Ecovacs W2 Pro Omni ↗.
Control is easy. The Ecovacs Home app offers 7 cleaning modes and a 360 degree remote control, and you can start a run from the station panel Ecovacs W2 Pro Omni ↗.
Results on well kept glass are good. Cybershack's hands on review gave it 87 out of 100 and found nearly streak free results on maintained windows in Thorough mode Cybershack review ↗.
Where it falls short
It is not a deep cleaner. Cybershack found poor results on grimy glass and about 70 minutes of battery in Thorough mode, well under the 110 minute rating Cybershack review ↗.
It wants the maker's solution. Cybershack found tap water left streaks and that Ecovacs' cleaning solution worked better, but called the solution expensive Cybershack review ↗. Pads also need frequent rinsing, because dirty pads cause streaks Cybershack review ↗.
It does not wash its own pads. That feature arrived with the pricier Winbot W3 Omni Ecovacs W3 Omni ↗.
The price moves a lot, so it pays to wait for a sale. Ecovacs lists it at $499.99, and Walmart has listed it at $699.99 Ecovacs W2 Pro Omni ↗ Walmart listing ↗.
