Is it worth it?
If your Saturday mornings keep disappearing behind a push-mower handle, Einhell’s Freelexo 500 BT promises to hand those hours back. Built for midsize suburban lawns up to roughly 5,400 ft², the red-and-black bot trims while you sip coffee inside and, unlike earlier ‘dumb’ robots, lets you tweak its schedule and zones from a phone. Add Battery-Power X-Change compatibility—meaning you can swap the same 18 V pack into drills or trimmers—and you have a compelling way to lighten the whole yard-care chore list.
After six weeks of real-world mowing in a bumpy 4,800 ft² backyard, I’m impressed by how quietly the Freelexo keeps grass at a golf-tee height yet still stumbles on tall spring growth and the occasionally glitchy Bluetooth app. It’s a match for tech-curious homeowners who already own Einhell batteries or have moderate slopes (up to 35 %), but impatient tinkerers or those with rough, knee-high grass may want to look elsewhere—or at least keep a backup push mower on standby.

Key Features
Bluetooth App Control
A dedicated Android/iOS app pairs via Bluetooth instead of Wi-Fi, so you can schedule mowing even in a backyard dead-zone.
Why it matters: no extra router or cloud account is required, protecting privacy and simplifying setup.
Example: I sat on the deck, changed Tuesday’s start time to 8 p.m. for a sunset barbecue, and the bot updated in under 5 seconds.
Multizone Navigation
Three configurable start points let the mower treat side yards or island beds as separate micro-lawns.
That prevents the classic ‘robot rut’ where the main lawn looks perfect but the far corner becomes a jungle.
In my yard the second zone entry sits behind a raised herb garden; the robot now visits that tricky strip every other day without getting lost.
Swappable Battery System
Instead of a sealed pack, Einhell uses its universal 18 V Power X-Change battery bay.
Why it works: one charger, dozens of compatible tools, and no downtime if you keep a spare cell.
Real-life bonus: when the mower docked with 20 % left, I yanked the pack, snapped it into my leaf blower, cleared the patio, then returned it for charging—one battery, two chores done.
Safety & Theft Protection
Collision, lift, and tilt sensors stop the blades within 1 second, while a PIN code and alarm discourage would-be thieves.
These safeguards comply with IEC-EN 60335 standards, giving peace of mind if kids or pets wander by.
A neighbor’s curious cat triggered the lift sensor; the blades halted instantly and the alarm beeped until I re-entered the PIN.
Firsthand Experience
Unboxing the Freelexo felt oddly like unpacking a mid-range laptop: neat cardboard trays, color-coded bags for pegs, and a glossy quick-start card that saves you from wading through the 100-page manual. The mower itself weighs about 31 lb, so I could lift it one-handed by the top handle without straining my back.
Installation is 80 % perimeter wire, 20 % actual robotics. It took me three hours to lay the 426 ft spool around two irregular flowerbeds, hammer the 190 plastic stakes, and test the loop with the app’s signal checker. A neighbor’s Husqvarna kit cost almost double and required a professional install; doing this one solo felt empowering—and cheaper.
During the first week I scheduled daily 6 a.m. runs. The dual-purpose alarm clock was the mower’s low 59 dB hum drifting through the open window; my dog barely lifted an ear. On day three a brief rain shower triggered the built-in sensor, and the robot scooted home automatically—a relief because my previous plug-in mower fried a board when left out.
Performance on grass under 3 in was stellar: a tidy, even cut and the sort of mulching that disappears into the thatch. Once growth passed 4 in, however, the Freelexo started ‘nibbling,’ leaving ankle-high tufts the size of poker chips. A quick double pass fixed it, but you need to stay ahead of fast spring growth.
After six weeks the 2.5 Ah battery still ends a 90-minute session with around 25 % charge, according to the app. Swapping in my 4 Ah Power X-Change pack extended runtime to 2 h 20 m, enough to finish the lawn in one shot. Maintenance has been limited to popping off the three razor-style blades every 3 weeks (four screws, five minutes) and spraying the chassis with a garden hose—no special tools, no drama.
Pros and Cons
Customer Reviews
Early adopters praise the Freelexo’s quiet cut and DIY-friendly installation, though a noticeable minority report app hiccups or struggles in very tall grass—common teething pains for mid-priced robo-mowers more than outright deal-breakers.
Climbs my 30 % slopes and rarely needs rescuing, but you must place the boundary wire perfectly
Installation was a breeze after watching Einhell’s videos, still mowing neatly three seasons later
Setup took an afternoon and now the lawn stays perfect while I sleep, only jams on hoses I forget to move
Mine barely cut, failed on a 5 % ramp—maybe defective but totally disappointed
Stops mid-run and erases its schedule, app feels outdated despite sharp blades
Comparison
Against Husqvarna’s entry-level 115H, the Freelexo costs roughly 30 % less and adds a removable battery, but the Husqvarna’s GPS-assisted navigation handles complex shapes with fewer boundary tweaks.
Worx’s Landroid S shares a similar cutting width yet uses Wi-Fi and OTA firmware updates, giving broader remote access—handy when you’re away on vacation. That said, Wi-Fi can be spotty at the back of a deep lot, where the Freelexo’s Bluetooth remains stable.
Traditional gas push mowers in the same price bracket deliver brute power and no charging downtime, yet they demand weekly labor, fuel, and far louder 90 dB noise. For homeowners trading sweat for smart automation, the Einhell sits at a sweet spot between premium GPS bots and basic cordless trimmers.
Frequently Asked Questions
- Does the mower work during rain?
- It will autonomously return to the dock when the built-in rain sensor detects moisture, protecting electronics and turf.
- Can I let it cut at night?
- Yes, but ensure wildlife isn’t active and note that condensation may shorten blade life.
- How often do the blades need replacing?
- Einhell suggests every 6–8 weeks
- Will one battery finish my lawn?
- The included 2.5 Ah pack covers roughly 4,500 ft² on a fresh charge
Conclusion
For tech-savvy homeowners with medium lawns and a shed full of Einhell gear, the Freelexo 500 BT is an appealing mid-tier robot: quiet, battery-shareable, and capable on moderate slopes. Keep the grass under four inches and the app within Bluetooth range, and it delivers a manicured yard with almost zero weekly effort.
If you need true remote control while traveling, have jungle-thick turf, or hate occasional app quirks, the value equation shifts—premium GPS models or a reliable self-propelled gas mower may suit you better. In its mid-$$$ price band, the Freelexo offers strong quality-to-cost, and seasonal discounts can make it a steal.
