About this listing
Who it suits
Framed or frameless windows from 11.8 x 15.7 in, with a 12.1 lb portable station that holds an automatic cable reel and safety rope. Suction is 5,500Pa, and it stays on the glass for 30 minutes if the power cuts out.
W2 PRO OMNI or W2S OMNI?
Both come with a station and the 30-minute power-cut hold. The W2S OMNI lists more suction (8,000Pa against 5,500Pa) and a rating for glass tilted up to 45°, which the W2 PRO OMNI’s page doesn’t give.
Does it need a wall outlet while it cleans?
No. The station holds a 4,500mAh battery, and ECOVACS lists about 110 minutes of cleaning per charge, with a full charge in 3 hours or less. An 18 ft (5.5 m) cord runs from the station to the robot, and a 3.3 ft (1 m) safety rope is included.
How long does a window take?
ECOVACS lists about 1 minute 45 seconds per 10.8 sq ft (1 m²) in Fast mode. It has 7 modes: Fast, Deep, Thorough, Edge, Spot, Zone and Heavy-Duty, set in the ECOVACS HOME app.
W2 PRO OMNI or W3 OMNI?
Both have a station and stay on the glass for 30 minutes or more if the power cuts. The W3 OMNI’s station also washes the pads (Vortex Wash), it adds TruEdge with Smart Lift for edges and corners, and it lists more suction while moving (3,300Pa against 2,800Pa). The W2 PRO OMNI is the simpler set-up: no pad washing, same app modes.
