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.

Full Price Match Policy

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.

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.

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 95% coverage, app control via Poolmate Bot, four cleaning modes (Auto, Floor, Walls and Waterline, Eco), enhanced lateral waterline jets, dual centrifugal pumps (versus single dual-inlet design), and 300-minute Eco runtime (versus 200 minutes max). 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. A one-touch main button starts the default Auto cleaning mode without app pairing. The app is required only for mode switching beyond Auto, scheduling, and remote start. Body indicator lights show battery status visually.

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 Auto mode with floor, walls, and waterline cleaning, expect 200-240 minutes. In Walls and Waterline mode (highest power draw), runtime is closer to 180 minutes. The 11,000 mAh battery is the same as the base Hydro 3 but managed differently per mode.

Does the Hydro 3S work with saltwater pools?

Yes. The 160W motor is tested for high-salt and high-chlorine environments with 200 m water pressure resistance. The salt- and chlorine-resistant motor construction is rated to last up to 3x longer than standard motors. Standard residential salt concentrations (up to typical 5,000 PPM range) are supported.

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 by 33% by lowering motor power, ideal for routine maintenance on cleaner days.

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

Yes. The Poolmate Bot 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 the patented lateral water jets clean 25% more edge area than the base Hydro 3. 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 residential use up to 1,614 sq. ft. Light commercial use (e.g., a small condo pool with low daily traffic) may work within those size limits, but the warranty applies to residential conditions. For dedicated commercial pools, the Hydro 4 or 4 SE corded models provide unlimited runtime and higher duty cycles.

Does the Hydro 3S need a separate charging dock?

No. The unit charges via a direct cable connection to its charging port. Some accessory wireless charging docks may be offered as optional add-ons but are not required for normal operation.

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.
