The Ecovacs Winbot W1 Pro is an older corded window cleaning robot with a cross water spray and planned back and forth cleaning paths. It still works for flat glass, but it was selling for about $366 at Amazon, close to what the newer, battery capable W2 Pro Omni often costs, so most buyers should pick the W2 instead.
What the Ecovacs Winbot W1 Pro is
The Winbot W1 Pro is a window cleaning robot from Ecovacs. It sticks to a window with suction, sprays water as it moves and wipes the glass with a cleaning pad, planning a back and forth route across the pane Ecovacs W1 Pro ↗. It works on flat glass, including mirrors and frameless windows, as long as the pane is at least 30 by 40 cm Ecovacs W1 Pro ↗.
It is a corded robot. It runs from a 4.7 meter power cord, with a small 650 mAh battery for power off protection Ecovacs W1 Pro ↗. A 1.5 meter elastic safety tether with a carabiner catches it if it ever falls Ecovacs W1 Pro ↗.
It has been superseded by Ecovacs' W2 and W3 models W2 Pro Omni ↗ W3 Omni ↗. We have not tested it ourselves. Hands on testing is in progress, and we will update this review with our results.
What it does well
The spray system is effective. A dual direction cross spray keeps a wide area of glass wet ahead of the pad Ecovacs W1 Pro ↗, and BestReviews, published by KTLA, called it thorough BestReviews via KTLA ↗. The robot holds 60 ml of water Ecovacs W1 Pro ↗.
Its path planning is reliable. Ecovacs' WIN-SLAM 3.0 plans a back and forth route, and an edge sensor reacts in 0.02 seconds, which helps on frameless windows Ecovacs W1 Pro ↗. BestReviews noted it works around obstacles and uses a forward and reverse motion for deeper cleaning BestReviews via KTLA ↗.
It gives you choices. There are three modes, fast, deep and spot clean Ecovacs W1 Pro ↗. Ecovacs rates its cleaning speed at about 2 minutes 50 seconds per square meter Ecovacs W1 Pro ↗.
It is light and simple. BestReviews lists it at 3.3 pounds BestReviews via KTLA ↗, and cleaning starts automatically once it connects to the Ecovacs app Ecovacs W1 Pro ↗.
Where it falls short
The app is Bluetooth only. BestReviews noted there is no Wi-Fi support BestReviews via KTLA ↗, so you need to stay near the robot to control it.
Reliability reports are mixed. BestReviews cited user reports of inconsistent sturdiness and battery life, including the robot stopping and asking to be connected to power even after being plugged in for hours BestReviews via KTLA ↗.
It needs an outlet. Unlike the W2 Pro Omni, which runs on battery for about 110 minutes or plugged in, the W1 Pro depends on its cord Ecovacs W1 Pro ↗ W2 Pro Omni ↗. That rules out windows far from a socket.
Its safety tether is short and basic compared with newer models. The W2 Pro Omni has a safety rope rated to 100 kg, a backup rope and a 30 minute hold if power drops W2 Pro Omni ↗.
Finally, the value case is weak. Ecovacs' own product page did not show a price for the robot when we checked, only replacement pads Ecovacs W1 Pro ↗, and the W2 Pro Omni has sold for $399 or less 9to5Toys ↗.
