How we put this guide together
We haven't bought or tested an Acemate Tennis Robot, so this isn't a hands-on review. Everything below comes from Acemate's own site (its product page, FAQ, Shipping Policy and Refund Policy pages, all read September 16, 2026), plus independent coverage: CNET's editor tried the robot at Acemate's CES 2026 booth, and a June 2026 write-up on Pongbot Community rounded up scattered Reddit and forum comments from actual owners. Acemate also gave AvaCoup a private code; when we tried it at checkout on October 7, 2026 it did not apply, so we've taken it off the site. Prices and stock below were re-checked on Acemate's product pages on October 7, 2026.
What Acemate sells
Acemate makes two robots. The original Tennis Robot S10 is an AI training device that moves on four Mecanum wheels, uses dual 4K binocular cameras to track your shots, catches the ball in an onboard net, and fires it back — either reactively in Rally mode (closer to hitting with a partner) or as a more traditional stationary Ball Machine/serve mode. It ships with the robot, one battery, one portable charger and a 1-year international warranty; a second year of warranty costs $99.99 extra. Acemate rates it for players from NTRP 1.0 to 5.0, on hard, clay or grass courts. Since mid-September Acemate has also taken pre-orders for the S10 Pro (details in the next section). Some of Acemate's own marketing materials and independent coverage also list different numbers for ball speed (60 vs 80 mph) and battery life (roughly 2 vs 3 hours) than the current product page; we're going with what's live on the product page today.
What it costs
Tennis Robot S10: $1,999, down from a regular $2,499, and in stock in all three plug versions (US, EU, UK) on Acemate's own product page, checked Oct 7, 2026. On Sep 16 it was listed at $2,199 with no stock in any version, so the price has moved more than once in a month — check the store before you buy.
Tennis Robot S10 Pro: $2,499 pre-order price (regular $2,999). Acemate says the pre-order runs Sep 16 to Oct 30, 2026, you pay in full at checkout, and the pre-order is 100% refundable until the robot ships; it estimates shipping starts around Oct 30, 2026 and calls that an estimate, not a guaranteed delivery date. On Acemate's own comparison, the Pro goes up to 75 mph (S10: 60 mph), holds 100 balls (S10: 80) and lists up to 5 hours of battery (S10: 3 hours) — the 5 hours is for Ball Machine mode at moderate settings, and Acemate says runtime drops in modes with more movement. The Pro weighs 23 kg (about 51 lb).
An optional 1-year extended warranty add-on is $99.99.
What buyers say
Acemate's own product page shows 97 buyer reviews averaging around 4.8–4.9 out of 5 (84% five-star), but those reviews are hosted and moderated by Acemate itself, and we couldn't find a Trustpilot profile for acematetennis.com to cross-check against — so treat that number as a starting point, not an independent score.
CNET's Matt Elliott tried the Acemate at its CES 2026 booth in Las Vegas (Jan 2026) on a mini demo court and gave it a "thumbs up" — he found it tracked and returned his shots with no awkward delay, though he expects it to struggle against harder-hitting players and pegged its realistic ceiling around USTA 3.5 and below. That's one short demo session, not long-term ownership.
A June 2026 write-up on Pongbot Community, summarizing scattered Reddit and forum comments from real owners, paints a more mixed picture: reported real-world catch rates ranging from roughly 25% up to a majority of shots — nowhere near "catches everything" — plus at least one owner reporting the unit stopping mid-session with an "incorrect position" error and a cracked net pole, slow follow-up from Acemate support on that case, and battery-life complaints as low as under an hour for some users against Acemate's own roughly 2-hour claim. The same write-up mentions, without being able to verify it independently, a claim that Acemate support advised against using the robot on Har-Tru clay courts. We're passing this along as secondhand reporting we found, not something AvaCoup verified directly.
How it compares
Numbers below are as reported by The Lasco Press, an independent tech/affiliate site that publishes its own comparison of Acemate against competing machines (checked Sep 16, 2026) — AvaCoup hasn't priced every competitor itself, so treat these as approximate.
| Acemate S10 | Spinfire Pro 2 | Lobster Elite | Slinger Bag | |
|---|---|---|---|---|
| Moves around the court | Yes (Mecanum wheels) | No, stationary | No, stationary | No, stationary |
| Catches & returns your shot | Yes | No | No | No |
| Approx. price | $1,999–$2,499 | ~$1,600 | ~$1,400 | ~$600 |
| Acemate S10 | Tennibot Partner V2 | Tenniix | |
|---|---|---|---|
| Catches your shot | Yes | No (hopper-based pickup, not a catching rally) | No |
| Weight | 17.8 kg (39 lbs) | — | ~8.5 kg, lighter/more portable |
| Approx. price | $1,999–$2,499 | ~$2,245 | — |
Traditional stationary machines are $600–$1,900 cheaper with long review histories, but none of them move or catch your shots — they just fire balls from one spot. Acemate's closest real competitor for a moving, catching rally robot is Tennibot; Tenniix is lighter but doesn't catch. If reliable, affordable ball feeding is all you want, a Spinfire or Lobster does that for much less money.
Shipping and returns
Shipping is free to the US, UK and EU (US orders may add sales tax at checkout depending on state). Everywhere else costs real money: Hong Kong $59.99, Singapore $479.99, Canada CAD$399.99, Australia AUD$399.99, and $699.99–$799.99 to most other countries including the UAE, Qatar and Saudi Arabia (Acemate's Shipping Policy page, checked Sep 16, 2026). Acemate also currently says delivery to several Gulf-region countries is temporarily suspended due to regional airspace closures — confirm directly with Acemate support if you're ordering from that region. Orders process within 48 hours and can only be changed or canceled within 24 hours of payment; delivery then runs about 4–8 business days to the US/UK/EU and 7–15 days elsewhere.
Returns run 30 days from the ship date for unused, undamaged units in original packaging with all accessories included; you pay return shipping unless the return is for a quality issue. Refunds process 1–2 business days after the warehouse confirms the item, but Acemate says its warehouse only processes returns once every two weeks, so the whole thing can take up to a month — worth knowing before you buy a $2,000+ item you might need to send back.
Who it suits
Worth considering if you're a solo player around beginner-to-intermediate level (Acemate's own NTRP 1.0–5.0 range, and CNET's tester put the realistic ceiling closer to USTA 3.5) who wants moving, reactive practice instead of a machine that just fires balls from one spot, and you're comfortable being an early adopter of a product that's still getting firmware updates and mixed reports on catch reliability. Skip it if you want a proven, cheaper ball machine with a long review history, if you need guaranteed-responsive customer support, or if you want the S10 Pro in hand right away — it's pre-order only, with shipping estimated to start around Oct 30, 2026.
Using the code
Acemate gave AvaCoup a private code but never told us what it discounts. We tried it at checkout on October 7, 2026 and it did not apply, so we've switched it off on AvaCoup rather than send you to a code that doesn't work. Right now the S10's own sale price ($1,999 vs $2,499 regular) is the only discount we can confirm. If Acemate gives us a working code, we'll test it and update this page.
