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.

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.

Financing Options

Split your purchase into 4 equal, biweekly payments at 0% APR with Shop Pay Installments — no hidden fees and no late fees. For larger orders, monthly installment plans may also be available, with rates from 0% APR or 10-36% APR depending on your purchase amount and eligibility.

Approval is fast and real-time: Shop Pay Installments is powered by Affirm and gives you a decision in seconds at checkout. Checking your eligibility is a soft credit check that does not affect your credit score, and while there are no late fees, partial or late payments may affect your eligibility to use the program in the future.

To qualify, you need a United States billing address and a U.S. mobile phone number that can receive SMS. Prefer PayPal? Choose PayPal Pay Later at checkout to split eligible purchases into interest-free installments (subject to PayPal approval).

Frequently Asked Questions

Does the Sunseeker X3 Plus need a boundary wire?

No. It navigates with AONavi Fusion, pairing RTK satellite positioning with Vision AI camera tracking. Position the RTK antenna with open sky, map the lawn in the Sunseeker app, and the boundaries live as virtual lines you can edit anytime.

What is Ride-on-Edge cutting?

It is the X3 Plus signature: the mower rides its wheel along walls, fences, and borders to trim the strip other robot mowers leave behind, cutting most string-trimmer work out of your routine. Systematic path planning covers the open lawn in clean passes rather than random bounces.

How much lawn can it handle, and how steep can it go?

It is rated for yards up to 0.3 acre (about 13,000 square feet) split into as many as 6 scheduled zones, and it handles slopes up to 30 percent (17 degrees), so it prefers yards on the flatter side.

How long does it run, and how fast does it recharge?

The 5 Ah battery recharges in about 90 minutes, keeping the mow-charge-mow cycle short. Cutting width is 7.9 inches with height adjustable from 1.6 to 3.2 inches.

How loud and how heavy is it?

It runs at a quiet 59 dB(A) and weighs 19.9 pounds at 23.9 x 15.0 x 9.8 inches, one of the lightest mowers in Sunseeker's range and easy to carry between areas. The body is rated IPX5, and it connects over Wi-Fi (2.4 GHz), Bluetooth, and 4G.

What is included in the box?

The Sunseeker X3 Plus mower, the charging station with charger, and the RTK antenna kit, shipped as Sunseeker's complete kit; see the product manual for the full accessory count.

What warranty does it carry?

Sunseeker covers the X3 Plus with its 2-Year Worry-Free Warranty for residential use; cutting blades are wear items and are not covered. Claims need a valid proof of purchase. RoboticsSelect is an authorized Sunseeker dealer, so claims run through us: email support@roboticsselect.com or call (412) 415-7375, Monday through Friday 9am to 5pm EST.

How do shipping and returns work?

Shipping is free within the contiguous United States: in-stock orders leave the warehouse in 3 to 5 business days and typically deliver 5 to 8 business days after dispatch, with tracking emailed at dispatch. You have 30 days from delivery to initiate a return on an unopened, unused unit; cancellations before shipment are free, elective returns after shipment incur return shipping and a restocking fee, and refunds are processed within 10 days of the return arriving.
