Aiper Scuba S1 and Aiper Scuba S1 Pro share a name and most of their hardware. Both are cordless robots that clean the floor, walls and waterline, both scrub with active brushes on tracks, and both pair a 180-micron basket with a 3-micron fine filter. The differences are fewer than the names suggest, and they do not all point the same way. The Pro is rated for larger pools and maps its route, while the current S1 runs longer per charge and lists steps. Assume either one fits your budget, because most of the choice comes down to your pool.
What Both Share
Aiper Scuba S1 and Aiper Scuba S1 Pro are both cordless, so there is no cable on the deck, and each carries a 7,800 mAh battery that Aiper says recharges in 4 hours. They clean the floor, walls and waterline, scrub with active brushes and move on tracks. Each pairs a 180-micron main basket with a 3-micron fine filter, both reached from the top, so one robot can catch leaves and much finer silt. Both can be scheduled from the Aiper app, both are cleared for saltwater as well as chlorine pools, and Aiper lists rectangular, round and free-form shapes for each, in in-ground and above-ground pools.
Pool Size
The clearest difference is the rating. Aiper rates Aiper Scuba S1 for pools up to 1,600 square feet or 50 feet long, and Aiper Scuba S1 Pro for pools up to 2,150 square feet or 66 feet long. Aiper gives both an area and a length, so check whichever is tighter for your pool. A long, narrow pool can sit within the area rating and still run past the length. If your pool falls between the two robots’ ratings, the Pro is the one rated for it. If your pool is well within the smaller rating, the Pro’s extra reach is less of a reason to choose it.
Runtime and Suction
Runtime goes the other way. Aiper quotes up to 4.5 hours per charge for the current edition of Aiper Scuba S1 and up to 3 hours for Aiper Scuba S1 Pro, so the S1 can keep going longer before it needs the charger. Both take 4 hours to recharge, so the S1 gives you more cleaning time from the same time on the charger. Suction is rated at 4,800 gallons per hour on the Pro and 4,200 on the S1. A rating does not tell you how either robot will do in your pool, though, so treat these figures as one factor among several.
Navigation, Steps and Finishes
Aiper lists advanced mapping for Aiper Scuba S1 Pro and a patterned path for Aiper Scuba S1. Both follow a planned route rather than wandering at random, and the Pro’s mapping is the more elaborate of the two systems.
Steps are where the S1 pulls ahead. Aiper lists step cleaning for Aiper Scuba S1 but not for Aiper Scuba S1 Pro, so if leaves tend to collect on your steps, the S1 is the one of the two whose maker says it covers them.
Pool finishes favor the Pro. Both robots are listed for vinyl, fiberglass, tile and gunite, and Aiper adds pebble and exotic finishes for Aiper Scuba S1 Pro, which the S1’s list does not include. If your pool has a pebble finish, that alone may decide it.

New or Renewed
One difference has nothing to do with cleaning. The Amazon listing for Aiper Scuba S1 Pro sells it as a renewed unit, while Aiper Scuba S1 is sold new. Aiper gives the S1 a 2-year warranty, so if you choose the Pro, check the warranty that comes with the renewed unit before you buy.
Which One Should You Choose?
Choose Aiper Scuba S1 Pro over Aiper Scuba S1 if your pool is larger than 1,600 square feet or longer than 50 feet, up to 2,150 square feet or 66 feet, or if it has a pebble or exotic finish. It has the larger rating, the higher suction rating and advanced mapping. In return, it runs for up to 3 hours per charge, Aiper does not list steps for it, and it is sold as a renewed unit.
Choose Aiper Scuba S1 if your pool is within 1,600 square feet and 50 feet, and especially if you want the steps cleaned or a longer run per charge. It lists steps, runs for up to 4.5 hours in its current edition, is sold new, and shares the Pro’s two filters, active brushes and app scheduling. If your pool is within its rating and has no pebble finish, the S1 covers the same floor, walls and waterline with the same filters.
