Which Einhell FREELEXO robot mower should I buy?

For most small, gently sloping lawns, the wired Einhell FREELEXO is the sensible choice; pick the Einhell FREELEXO CAM only if your lawn is flat with clear edges and you really don't want a wire. The Einhell FREELEXO LCD BT is the one for bigger lawns, if you can find it in stock.

The FREELEXO is the newest and cheapest, at £409.95 RRP. It follows a perimeter wire, handles slopes up to 35%, and adds Wi-Fi app control and over-the-air updates. It's rated for 500 m².

The FREELEXO CAM, at £649.95 RRP, uses a camera instead of a boundary wire, apart from a short guide cable at the dock. It has no app and a lower 25% slope rating, and it relies on the lawn having edges it can see.

The FREELEXO 1200 LCD BT, at £752.95 RRP, is the older wired model with an LCD keypad and Bluetooth-only app, rated for 1,200 m². It showed as out of stock at Einhell UK when we checked.

All three run on Einhell's 18 V Power X-Change batteries, so owners of other Einhell tools can share packs. All carry a two-year warranty, extended to three years if you register online within 30 days. See the Einhell brand page for current prices.
