Wybot Pool Cleaners

Why a spec sheet is a reason to look

In a category where most listings publish a mode count and a marketing name, a brand that prints coverage area, micron rating, runtime and warranty is telling you something before you read a single review.

It also makes the four-number check we recommend actually possible. You cannot compare a robot against your pool's area if nobody has published an area figure, and for several models in this range you can.

The range, on Wybot's own published figures

Every figure in that table comes from Wybot's own product pages, read on 2026-09-02. Where a cell says 'not published', that is what we found rather than a gap we chose to fill.

The C2 is the interesting one

Wybot publishes a 10 micron ultra-fine filter sitting behind a 180 micron primary. That is the finest filtration figure any maker in our roundup states, and it addresses the complaint most robots do not: the pool is leaf-free and the water is still hazy.

180 micron catches leaves, grit and insects. Silt, pollen and fine dead algae pass straight through and go back into the water, however many cycles you run. A second stage at 10 micron is what stops that - at the cost of cleaning the filter more often, because it is now catching material it previously passed.

The B1 shows how sizing should work

Wybot rates the B1 for pools up to 1,150 sq ft with 120 minutes of runtime. That published pairing is more useful than a runtime figure alone, because it already accounts for how the machine moves.

The S3 is a different kind of product

Every other robot here is a device you carry to the pool, drop in, retrieve and empty. Wybot's S3 docks itself, recharges itself and empties into a shore-based bin. Its own page states 3D mapping on the first run, route planning from that map afterwards, a 10 L self-sanitizing debris bin, and maintenance reduced to around once a month.

That changes the ownership model rather than the cleaning. It is also the most mechanically complex machine on this site and the most expensive, and those are the same fact.

The picks

Top pick - Finest published filtration

Wybot C2 Cordless Pool Vacuum for In-ground Pools

A 10 micron secondary filter is the finest figure published by any robot here, and it is the one that decides whether the water looks clean afterwards.

The published figure

180 min runtime, up to 2,152 sq ft per cycle, 10 micron ultra-fine plus 180 micron primary filter

Wybot's own product page states a 10 micron ultra-fine filter behind a 180 micron primary. Most robots publish one number or none at all.

That matters because 180 micron catches leaves and grit while fine silt, pollen and dead algae pass straight through and go back into the water. The second stage is what stops that.

Wybot also publishes coverage per cycle — 2,152 sq ft — which is the honest way to compare against your own pool rather than against a runtime number in isolation.

What it does well

• 10 micron secondary filtration, the finest published figure in this roundup
• Coverage published per cycle, not just runtime
• Three brushless motors driving suction

What it costs you

• Fine filtration means more frequent filter cleaning
• 180 minutes is shorter than the longest-running units here

Skip it if your pool only ever collects leaves. You would be paying for filtration you never use.

Pick 2 - Small pools

Wybot B1 Cordless Robotic Pool Cleaner

Explicitly rated for pools up to 1,150 sq ft, which is a more useful number than a runtime figure with no area attached.

The published figure

Rated by the maker for pools up to 1,150 sq ft, 120 min runtime, 180 micron filter

Wybot publishes a coverage area for this unit rather than leaving you to infer it. 1,150 sq ft is roughly a 16 x 32 pool including the walls.

Buying a unit rated well above your pool wastes money; buying one rated below it means the cycle ends before the pool is done. The published area is how you avoid both.

180 micron single-stage filtration here, not the dual stage of the C2. That is the trade at this size and price.

What it does well

• Coverage area published, so sizing is a decision rather than a guess
• Compact and light to lift out
• Quad roller brushes for edge work

What it costs you

• Single-stage 180 micron filter passes fine silt
• 120 minutes is short for anything above its rated area

Skip it if your pool is larger than about 1,150 sq ft. The maker's own rating is telling you not to.

Pick 3 - Wall and waterline on a budget

Wybot C1 Cordless Robotic Pool Vacuum

Wall and waterline cleaning in a cordless unit priced below the flagship models, at the cost of the dual-stage filter.

The published figure

Cordless, wall-climbing and waterline cleaning, four-in-one cleaning modes

Waterline cleaning is the feature most often dropped from cheaper robots, and it is the one that visibly changes how a pool looks — the scum line sits exactly there.

Wybot positions the C1 around that capability, which makes it the value pick if the waterline is your complaint.

It carries the single-stage filter rather than the C2's dual stage.

What it does well

• Waterline cleaning at a price where it is usually omitted
• Cordless, so no cable management
• Multiple cleaning modes rather than one fixed cycle

What it costs you

• Single-stage filtration
• Shorter runtime than the flagship units

Skip it if fine silt is your problem rather than the waterline — the C2's second filter stage is what you want.

Pick 4 - Hands-off ownership

Wybot S3 Robotic Pool Cleaner

Docks, recharges and empties itself, which the maker states cuts hands-on maintenance to roughly once a month.

The published figure

3D mapping navigation, auto-docking with self-emptying to a shore bin; maker states around monthly maintenance

Every other robot here is a device you carry to the pool, drop in, retrieve and empty. This one docks and empties into a shore-based bin, which changes the ownership model rather than the cleaning.

Wybot's own page describes 3D mapping on the first run and route planning from that map on later runs, plus a 10 L self-emptying debris bin.

That is a lot of mechanism to go wrong, and it is the most expensive item on this page. Both facts are the same fact.

What it does well

• Self-docking and self-emptying, so the routine chore mostly disappears
• Maps the pool rather than running a fixed pattern
• Largest debris capacity here at 10 L

What it costs you

• The most complex and most expensive unit in this roundup
• Requires shore-side space for the dock

Skip it if you are happy to lift a robot out once a week. That habit is what this price premium replaces.
