Engineered for large multi-lane commercial, club, and municipal pools.

Prevents tangles across long overnight commercial runs.
The Wave 140 is the top of Maytronics' commercial range — the machine specified for the largest institutional pools, where a residential robot would still be working at closing time.
Six-hour cleaning cycles and a chassis sized to match. This is equipment for competition pools, water parks and resort complexes, not for a domestic backyard — for that, the Wave 60, 80, 90i, 100 and 120 in our own range step down through the sizes.
Independently driven tracks keep a machine this large agile enough to work around lane anchors, ladders and gutters rather than getting hung up on them.
Top-load fine cartridge with a full indicator — on a commercial machine, knowing when the filter is loaded without opening it is what keeps the cleaning schedule on track.
This is a commercial purchase with a price to match, and it has essentially no Amazon review history. If you're specifying a commercial cleaner, talk to us first — we sell the Wave range and can advise on sizing properly rather than guessing from a listing.
Ordering for a hotel, HOA, YMCA, or university? we carry the Wave 80, Wave 90i, Wave 100, and double-wide Wave 120 directly—chat with our commercial team for sizing help.
