Price Match Guarantee

We match the lowest online price on the products we sell — and if you find a lower price on a product listed over $2,000, we will beat it by $50. Purchase from our store first, then send proof of the lower price (a screenshot, invoice, or email) to support@roboticsselect.com and we will refund the difference.

A few requirements: the competitor must be an authorized online retailer of the product with the item in stock on their website, must be online-only (no retail location), and cannot be a discounter or auction site such as eBay or Overstock. The comparison includes the item price and shipping charges but excludes sales tax.

Rebates, buy-one-get-one offers, and special once-a-year promotions such as Black Friday and Cyber Monday are not eligible. Certain exceptions may apply.

Returns & Refunds

Cancel any time before your order ships for a full refund, free of charge. Custom and made-to-order products are put into production for your specific order, so all sales are final on those items.

You have 30 days from the date you receive an item to start a return — email support@roboticsselect.com or call (412) 415-7375. Products must be returned unopened and unused. Some brands set their own return terms, and the brand-specific policy on the product page overrides the general 30-day window; if the manufacturer will not permit a return, we cannot offer one.

Outright returns after shipment incur a 25% cancellation fee plus return shipping, and manufacturer restocking fees (usually around 20%) may also apply — return shipping costs are the customer's responsibility. Refunds go to your original payment method and are processed within 10 days of our receiving the returned product.

Inspect the package when it arrives: note any damage when signing for delivery and send photos to support@roboticsselect.com within 24 hours — freight damage claims are not valid after 24 hours.

Full Refund Policy

Shipping & Delivery

Standard curbside delivery is always completely free. Most orders ship out within 1-5 business days, and delivery takes 5-8 business days once shipped (estimated delivery 6-13 business days). All shipping times are estimates and can vary by brand, especially for made-to-order items.

Orders ship fully tracked via USPS, UPS, or FedEx, and we email your tracking information within 24 hours of the order leaving the warehouse. If tracking hasn't arrived within six business days of ordering, contact support@roboticsselect.com.

Upgraded delivery options are also available: Threshold Shipping brings the item onto your porch or into a sheltered/garage area, and White Glove Delivery brings it into your room of choice, includes minor assembly, and removes all packaging.

We do not ship outside the USA, with limited exceptions — if checkout accepts your shipping address, we can deliver to it.

Chasing Hydro 3S Cordless Robotic Pool Cleaner

Overview

The Chasing Hydro 3S is a cordless robotic pool cleaner for small to medium pools. Unlike the entry Hydro 3, it uses Chasing's HydroCurve S-shaped navigation, which plans an efficient path that covers up to 95 percent of the pool with about 30 percent less overlap than random-path cleaners. It cleans the floor, the walls, and the waterline, and you control it from the Chasing app.

Two centrifugal pumps pull water through twin inlets at up to 320 liters per minute (5,070 gallons per hour). A dual-zone filter basket traps leaves and larger debris in the front and fine sand and gravel in the rear. A single charge runs for up to 200 minutes, and an Eco mode extends cleaning to up to 300 minutes for longer, energy-efficient cycles.

It is built for owners of small to medium pools, up to about 1,614 square feet, who want smarter coverage and app scheduling with the freedom of a cordless design.

Applications

Chasing Hydro 3S deployed in a mid-sized inground residential pool

The Hydro 3S suits homeowners with small to medium pools, up to about 1,614 square feet, who want smarter coverage than a random-path cleaner. Its HydroCurve S-shaped navigation adapts to round, L-shaped, and freeform pools and handles slopes, steps, and corners.

It works on concrete, vinyl, fiberglass, and tile. With up to 200 minutes of runtime, and up to 300 minutes in Eco mode, it completes a thorough clean on a single charge, and the app lets you schedule cleaning and fine-tune the floor-to-wall cleaning ratio.

For owners who want app scheduling, water temperature readout, and planned coverage in a cordless unit, the Hydro 3S sits a step above the entry Hydro 3 while staying easy to handle.

Setup and Getting Started

Charge the battery: Open the rubber cover on the charging port and charge the unit fully with the included adapter before the first run. A full charge takes about 4 hours, and the cover goes back on afterward.
Install the app and pair: Download the Chasing app, create or sign in to an account, and pair the unit for scheduling and remote control.
Select a mode before submerging: Choose a cleaning mode on the unit or in the app before lowering it into the water, since the Bluetooth link drops once the unit is submerged.
Check the filter basket: Make sure the 4.1 L dual-zone basket is seated correctly. Fit the optional hyper-fine filter if your pool has very fine particles.
Drop and run: Lower the unit into the water and start the cycle so it can plan its S-shaped path across the pool.
Set a schedule: In the app, set a weekly schedule and adjust the floor-to-wall cleaning ratio to match your pool.
Collect and recharge: When the cycle ends, the unit docks at the pool edge. Lift it out, rinse the basket, and recharge for the next run.

Frequently Asked Questions

How is the Hydro 3S different from the base Hydro 3?

The Hydro 3S adds intelligent S-shaped path navigation (HydroCurve) for up to 95% coverage, app control via the CHASING GO3 app, four cleaning modes (Auto, Floor, Walls and Waterline, Eco), patented lateral waterline jets, and 300-minute Eco runtime (versus 200 minutes max on the Hydro 3). Both models use the same twin-inlet, dual centrifugal pump suction system. Pool size capacity also increases from 1,076 sq. ft. (Hydro 3) to 1,614 sq. ft. (Hydro 3S).

Can I use the Hydro 3S without the app?

Yes. The slide switch on the unit starts a cleaning cycle without app pairing, and switching it off and back on within 5 seconds changes the cleaning mode. The app adds scheduling, remote start, and the floor-to-wall cleaning ratio setting. The body indicator light shows battery level, charging status, the selected mode, and faults.

How long does the 300-minute runtime actually last in real-world use?

The 300-minute spec applies specifically to Eco mode, which uses lower motor power for extended runtime. In the other modes Chasing rates the Hydro 3S at up to 200 minutes per charge; actual runtime depends on pool size, debris load, and how much wall and waterline cleaning the mode includes. The 11,000 mAh battery is the same capacity as the base Hydro 3 but managed differently per mode.

Does the Hydro 3S work with saltwater pools?

Yes. The motor (150W peak) is sealed to IP68 with an anti-chlorine coating for salt and chlorine environments, and Chasing rates its salt- and chlorine-resistant construction to last up to 3x longer than standard motors. Chasing rates the unit for both saltwater and chlorinated residential pools.

What's the difference between the four cleaning modes?

Auto runs the full cycle covering floor, walls, and waterline. Floor focuses suction on the pool bottom for debris-heavy days. Walls and Waterline targets vertical surfaces and the tile line for stain removal. Eco extends runtime to up to 300 minutes (from 200) by lowering motor power, ideal for routine maintenance on cleaner days.

Can I schedule the Hydro 3S to clean automatically each week?

Yes. The CHASING GO3 app supports weekly schedules with custom day/time settings, runtime length, and mode selection per scheduled run. Delay-start timers also let you queue the next cycle.

How does the HydroCurve algorithm differ from random-path cleaners?

Random-path cleaners change direction only when hitting obstacles, which produces inconsistent coverage and occasional missed areas. HydroCurve plans S-shaped sweeps that cover the pool systematically (back-and-forth in straight lines, like a lawnmower), reaching up to 95% coverage with less cycle time. The algorithm adapts to non-rectangular pool shapes.

Will the Hydro 3S clean my pool's tile waterline?

Yes. The Walls and Waterline mode specifically targets the tile line, and Chasing rates the patented lateral water jets to clean 25% more edge area than top-jet designs. For heavy mineral buildup, periodic manual scrubbing in addition to the robot is recommended.

Is the Hydro 3S powerful enough for a small commercial or HOA pool?

The Hydro 3S is rated for pools up to 1,614 sq. ft. Light commercial use (e.g., a small condo pool with low daily traffic) may work within that size limit. For dedicated commercial pools, the corded Hydro 4 and Hydro 4 SE run continuously on AC power with no runtime limit, and Chasing positions its Hydro 6 and DT 100 for large and commercial pools.

Does the Hydro 3S need a separate charging dock?

No. The Hydro 3S has a built-in battery that charges through a port under a rubber plug on the unit, using only the supplied Chasing power adapter; a full charge takes about 4 hours. There is no floating battery buoy and no dock to buy. Dry the port before connecting the adapter.

What additional protection do I get buying from RoboticsSelect as an authorized Chasing dealer?

RoboticsSelect is an authorized Chasing dealer, so the full 24-month manufacturer warranty applies to all Hydro 3S purchases. Authorized dealer status also ensures Chasing's after-sales service team handles warranty claims directly with verified proof of purchase, which is essential because warranty processing requires confirmation that the unit was sold through a legitimate retail channel.
