Because it’s designed for compact urban lawns, the SILENO City packs practical specs: it covers up to 5,400 sq ft, tackles slopes up to 35% (19°), operates at a low 57 dB(A), and runs long enough for routine maintenance without constant intervention.

The SILENO City is a solid choice for homeowners who prioritize battery-powered yard care and battery-powered mowers for enjoying their outdoor space.

How It Performs on Real Lawns: Cutting Quality, Navigation, and Noise

Put simply, the SILENO City delivers consistent, turf-friendly cuts and smart navigation with impressively low noise. You’ll notice the patented streak-free pattern leaves even grass discharge and clippings dispersed without scalping. Navigation handles narrow passages and tight corners, so you feel confident your lawn looks uniform. Edge trimming near borders is tidy though not razor-sharp—occasional touch-ups help. Noise stays around 57 dB(A), letting you relax while it works. Monitor blade wear and battery health periodically; both affect cut quality and runtime. Overall, the mower performs reliably on real lawns, fitting neatly into shared garden routines. It’s a great option for homeowners who enjoy caring for their outdoor spaces with hover mower basics.

Setup, Daily Use, and Safety Features You Need to Know

Before you let the SILENO City loose on your lawn, set aside a couple of hours for the boundary-wire layout and base-station placement so the mower has a clear, efficient working area. You’ll appreciate straightforward installation tips: the kit includes wire, staples, and clear guides plus videos, making DIY setup manageable. Daily use is simple—auto-schedule and EasyConfig keep mowing autonomous and reliable. Safety features are solid: lift and collision sensors stop blades instantly, and the boundary wire prevents escapes. You’ll feel confident joining other owners who value quiet, dependable operation and practical, well-documented setup. For homeowners who use outdoor power systems, consider how integrating a battery solution can keep your base station and charging needs efficient.

Costs, Durability, and Final Buying Recommendation

While the SILENO City carries a higher upfront cost than basic push mowers, you’ll find its long-term value reasonable given the time savings, consistent cut quality, and all-weather reliability. You’ll pay more initially, but long term maintenance is minimal: blade swaps, occasional software updates, and annual checks. Battery replacement cost matters — budget for a replacement after several years if you keep the mower. Resale value stays fair for European-made, well-kept units. Seasonal storage is simple: clean, charge, and store in a dry spot. Recommendation: buy if you want a reliable, low-effort lawn routine and community pride.

Some Questions Answered

Does It Come With a Warranty and What’s Covered?

Yes—you get a warranty, typically a 2-year warranty duration covering defects in materials and workmanship. You’ll have coverage for manufacturing faults, motor and electronic failures, and functional defects under normal use. Coverage exclusions usually include damage from misuse, improper installation, unauthorized repairs, consumable wear (blades, batteries over time), and accidents or environmental damage. Check your local dealer for exact terms so you and your lawn feel supported.

Can It Be Controlled via Smartphone or App?

Yes — you can control it via smartphone integration. You’ll use the app for remote scheduling, start/stop commands, and basic settings, so you won’t feel tied to the garage. The app’s functionality is straightforward and reliable, offering status updates and scheduling convenience. It won’t replace local boundary setup, but it complements autonomous operation well, helping you and fellow gardeners feel connected and confident in your lawn care routine.

You should use genuine GARDENA replacement blades and matching mounting hardware for reliable, streak-free cuts and safe operation. Choose the manufacturer’s three-point razor blades or approved blade sets designed for this model, replacing them every few months or when nicked. Keep spare mounting hardware (screws, clips) on hand to avoid downtime. If you want reassurance, buy blades and hardware from authorized dealers so you and your lawn stay supported.

How Long Is the Battery Lifespan and Replacement Cost?

You can expect the battery lifespan to be about 3–5 years with typical use; battery degradation gradually reduces runtime over seasons. Replacement pricing ranges roughly €120–€220 (varies by region and supplier). You’ll want to budget for eventual replacement and check original vs third‑party options. You’ll stay in the community of users who’ve found swapping batteries straightforward, and you’ll extend life by avoiding full discharges and extreme temperatures.

Is There Theft Protection or GPS Tracking Built In?

No, it doesn’t include built-in GPS tracking, and its anti theft measures are basic. You’ll get PIN-lock and lift/tilt sensors that stop blades and sound an alarm, which helps keep the mower secure within your community. If you want full GPS tracking or geofencing, you’ll need an external tracker or a premium model offering connected services. That said, the included safeguards still provide useful neighborhood-level protection.
