Quick Answer: Kärcher — the pressure-washer brand most Americans already know from Home Depot and Lowe’s shelves — makes a real robot mower, the RCX 6, but it still isn’t sold in the US as of September 2026. The RCX 6 is a wire-free, all-wheel-drive machine using RTK GPS plus vSLAM camera vision, rated for lawns up to 3,000 m² (about 32,300 sq ft) and slopes up to 70%, priced around €2,799-€3,299 in Europe since its 2025 launch, per Kärcher’s own international product page. Kärcher has only said a US release “remains to be seen.” If you want that spec sheet today, the closest US-available equivalents are the AWD Mammotion Luba 3 AWD and Segway Navimow flagships, both of which actually ship to US addresses with US support.
If you searched “Kärcher robot mower” expecting to find it on Amazon next to your Kärcher pressure washer, you’re not wrong that it exists — you’re just looking in the wrong country. Here’s the honest breakdown of what the RCX 6 actually is, why it’s stuck outside the US, and what to buy here instead.
The RCX 6 is real — it’s just not a US product
Kärcher presented the RCX 6 as its “new generation” of robotic lawnmowers, and it’s a legitimate flagship-tier machine, not a rebadge or a concept. Per Kärcher’s own product pages and press materials, it navigates without a perimeter wire using RTK GPS, a dedicated reference antenna, and vSLAM camera vision, backed by shock sensors for obstacle response. All-wheel drive lets it handle up to a 70% slope — a higher rating than most US-market flagships publish — and it covers up to 3,000 m² (about 32,300 sq ft, or roughly 0.75 acre) on a single mapped layout, running about 50 minutes per charge with a 5,000mAh battery that recharges in roughly an hour.
It launched in Europe in 2025 and has been sitting on European retail shelves and Amazon.de-style listings ever since, priced from roughly €2,799 to €3,299 depending on the retailer and promotion. That’s not a rumor or a CES prototype — it’s a shipping product with real reviews and real owners, just none of them in the US.

Why “not in the US” is a genuinely unusual gap
Most brands with no US robot mower presence are either dealer-only imports (Ambrogio) or discontinued lines (Honda Miimo). Kärcher is different: it’s already a large, familiar US retail brand. Its pressure washers and window vacs sit on shelves at Home Depot and Lowe’s right now, and it has US customer support infrastructure for those product lines. That makes the RCX 6’s absence a genuine availability gap rather than a “this brand doesn’t sell here at all” situation — the company has the US retail footprint to bring a robot mower over; it simply hasn’t.
What to buy instead in the US: Mammotion Luba 3 AWD
- 80% (38.6°) slope rating and all-wheel drive puts it in the same climbing class as the RCX 6's 70% figure, per Mammotion's own spec sheet.
- Tri-Fusion Navigation (360° LiDAR + NetRTK + AI vision) skips the separate RTK antenna the RCX 6 still requires, while matching its no-perimeter-wire convenience.
- US retail listings, US support, and an established track record on this site's [Mammotion vs Husqvarna](/compare/mammotion-vs-husqvarna/) and [Luba 3 AWD](/best/mammotion-luba-3/) coverage.

Kärcher RCX 6 by the numbers
- 70%: The RCX 6’s published maximum slope rating — higher than most US-market wire-free flagships, per Kärcher’s own spec sheet.
- 3,000 m² (~32,300 sq ft): Maximum single-mower coverage area, roughly 0.75 acre.
- €2,799-€3,299: The realistic European price range since its 2025 launch, depending on retailer and promotion.
- 0: The number of US states, retailers, or Kärcher.com/us listings currently selling the RCX 6, as of September 2026.
The bottom line
The Kärcher RCX 6 is a legitimate, well-specced AWD robot mower — not vaporware, not a dealer-only oddity, just a European product from a brand that already has a large US retail footprint for its other tools. If Kärcher brings it stateside, its 70% slope rating and wire-free RTK-plus-vision navigation would make it a credible flagship competitor. Until then, US buyers who want that spec sheet should look at the Mammotion Luba 3 AWD or a Segway Navimow flagship — both actually ship here.
