Last updated: October 2026

The B1 cleans floor, walls and waterline up to 1,150 square feet. The C1 covers up to 1,615 square feet with app scheduling. The C2 covers up to 2,152 square feet and adds a 10 μm ultra-fine filter.

How do the four compare?

All figures are WYBOT's.

Where WYBOT's listing for a model does not state a feature, the table says "not listed". Ask us if one of those matters to you and we will check with WYBOT.

Does the WYBOT A1 climb walls?

No. WYBOT lists the A1 as floor only, for all pool types with a flat bottom and a maximum slope under 15°. It is the simplest model in the range.

• Pools under 1,076 sq ft.
• Up to 120 minutes of continuous run time.
• Dual-motor power with a 180 μm filter.
• Cycle timer: set the frequency, up to 4 times in 7 days.
• Edge-enhanced cleaning along the base of the walls.
• Self-parking for retrieval.
• 1-year warranty.

Suits: above-ground pools and flat-bottom in-ground pools where the walls stay clean or you brush them yourself.

What does the B1 add?

The WYBOT B1 is compact and climbs.

• Floors, walls, waterline, steps and slopes, on various materials including tile.
• Pools up to 1,150 sq ft, with up to 120 minutes of run time.
• Triple-motor power, a quad-roller brush and a 180 μm filter.
• Dedicated side brushes for walls and corners.
• App control with OTA updates and several cleaning modes.
• LED status indicators and a quick-release modular design for replacing core parts.
• 1-year warranty.

Suits: smaller in-ground pools where you want the walls and waterline done, in a body that is easy to lift.

What does the C1 add?

The WYBOT C1 moves up in pool size and control.

• Floors, walls, waterlines, steps and slopes for pools up to 1,615 sq ft.
• Up to 150 minutes of run time.
• 5 modes: full, floor, wall, wall then floor, and Eco floor.
• S-path and N-path navigation.
• 180 μm filter, 3,038 GPH suction and dual PVC brushes.
• App control: customize modes, schedule weekly cleaning and receive OTA updates.
• Self-parking near the pool wall.
• 2-year warranty.

Suits: mid-size pools, and owners who want schedules and modes from a phone.

What does the C2 add?

The WYBOT C2 is the top of these four.

• Floors, walls and waterlines for pools up to 2,152 sq ft.
• 180 minutes of run time in Eco mode.
• Dual-layer filtration: a 180 μm cartridge for large particles plus a 10 μm ultra-fine filter for fine dust.
• 7 cleaning modes and 6 paths in the WYBOT app.
• Schedule up to 4 cleanings a week.
• Works on tile, concrete, vinyl and fiberglass, per WYBOT.
• Brushless motor and auto-parking.
• 2-year warranty.

Suits: larger pools, and pools with fine dust, pollen or sand that pass through a standard filter.

Why does the 10 μm filter matter?

A 180 μm filter is good for leaves, bugs and grit and keeps water flowing. Fine silt, pollen and dead algae are much smaller and pass through. The C2's second layer, at 10 μm, catches that fine material. If your water looks dusty after a clean, or you fight algae dust, this is the feature to pay for.

How do you size one to your pool?

Measure the pool's surface area in square feet.

• Rectangle: length x width. A 16 x 32 ft pool is 512 sq ft.
• Round: 3.14 x radius x radius. A 24 ft round pool is about 452 sq ft.
• Freeform: average length x average width x 0.85 as an estimate.

Then pick a model rated comfortably above that number. A robot working near its limit finishes with an empty battery and may not complete the walls.

Which one for an above-ground pool?

Most above-ground pools have a flat floor, which is the A1's job. If you want the walls and waterline cleaned too, step up to the B1. Vinyl is on WYBOT's surface list for the C2.

What about larger pools?

Above the C2, WYBOT makes the S2, rated for pools up to 3,230 sq ft with up to 210 minutes of run time and a 3 hour quick charge, and the S3, which docks, recharges and empties itself. See what is the WYBOT S3? There is also the C2 Vision, a C2 with a camera-guided floor mode.

Should you add the F1 skimmer?

If leaves land on your pool, yes. The WYBOT F1 is a solar skimmer with a 33 W panel and a 7 L basket that collects floating debris before it sinks. WYBOT bundles it with each floor robot, such as the C2 + F1 bundle. A skimmer on top and a robot on the floor is the pairing that keeps up under trees. See do robotic pool cleaners pick up leaves?

What about shipping and returns?

WYBOT ships these products. Shipping is free in the continental US. Orders are processed within 2 business days and usually arrive in 3 to 7 business days. WYBOT does not ship to Alaska, Hawaii, Rhode Island, US territories or PO boxes.

Warranty is 1 year on the A1 and B1 and 2 years on the C1 and C2, per WYBOT.

How do you care for a WYBOT?

Lift it out after each cycle, empty and rinse the filter, rinse the body with fresh water, and store it in the shade. Do not leave it in the pool for weeks. See can you leave a robotic pool cleaner in the pool? Before winter, follow how to store a pool robot for winter.
