European price classes
Mid-range
€200–€350
Upper mid-range
€350–€550
Premium
€550+
The lowest documented European price selects the class. Within ±10% of a boundary, both neighbouring classes are calculated and the better result counts.
Mandatory category features
CE marking and EU conformity (low voltage/EMC, plus RED for radio operation)
Safety rope (fall protection) included, with a secure anchor point (carabiner, suction cup or station)
Emergency/backup battery keeps the suction hold after a power failure (documented hold time, market standard from approx. 20 minutes)
Edge/anti-fall detection: detects glass edges and frames and stops before the edge
If operation requires an app: app available in the EU app stores and usable in German or English (sign-up from the EU possible)
Expected features by price class
Budget
- Systematic path navigation (Z/N pattern, no random pattern), automatic stop when finished
- Remote control included or app control with start/stop, direction and mode selection
- Washable microfibre pads, several included in the box
Mid-range
- Integrated spray function (at least 1 nozzle) with water tank instead of manual pad wetting
- App control (BT/Wi-Fi) with multiple cleaning modes in addition to the remote
- Suitable for or approved for frameless windows/glass surfaces (edge detection without frames; manufacturer claim or review)
- Backup battery maintains suction for approx. 30 minutes or longer (manufacturer claim or review)
Upper mid-range
- Multiple/wide-angle spray nozzles (at least 2) with metered water output
- Portable station/case with built-in battery: operates without a nearby power outlet
- Declared near-edge cleaning: dedicated edge/border mode, dedicated edge/border sensing or manufacturer figure for the remaining edge gap
Premium
- Station washes/wets the cleaning pads automatically (pad self-cleaning)
- Dedicated hardware for edge and corner cleaning: extendable edge wiper, border scrubber or equivalent solution
- Spray system wets the entire wiping width (at least 3 nozzles or equivalent full-width water distribution)
- Mains-independent cleaning for approx. 100 min or more per charge (approx. 50 sqm and more)
- Automatic adaptation to the pane: detects size/shape of the glass and plans the route accordingly, or re-cleans heavily soiled spots (manufacturer claim or review)
Above-class bonus features
- Equipment clearly above class expectation (e.g. spray/app in budget, battery station in mid-range, pad washing in upper mid-range)+4
- Local control without forced cloud (direct Bluetooth control or remote covering all core functions)+4
- Backup battery maintains suction clearly longer than usual (approx. 45 min or more)+3
- Dual-cloth system: wet-wipes and dries in one pass (fewer streaks)+4
- Approved for roof windows/sloped glass surfaces (manufacturer claim)+3
- Operating noise below approx. 65 dB(A) (manufacturer figure or measurement in a review)+3
- Approved for frosted/satin or lightly textured glass (manufacturer claim)+2
- Also cleans small panes from approx. 40 x 40 cm (muntin/period windows)+3
- Tensile load of the safety rope documented by the manufacturer (approx. 100 kg or more) or redundant second securing+3
- Voice assistant/smart home integration (Alexa, Google Home or similar)+2
- Backup/operating battery user-replaceable or available as a spare part+3
- Wear and spare parts available from EU retail (cleaning pads, sealing lips/rubber rings, power cable, safety rope)+3
- Audible alert on malfunction or power failure (beeper on the device, not just an app notification)+2
- Extensive accessories out of the box (approx. 6+ pads, cleaning solution, extension cord/rope)+2
Negative characteristics
- Repeatedly and independently documented loss of adhesion/falls in normal operation (reviews or recurring user reports)-8
- Repeatedly documented severe app/connectivity defects (dropped connections, device cannot be paired) in reviews or ratings-4
- Core app operation only possible with a cloud account and the app's privacy policy that was found is available exclusively in a language other than German or English (evidence: app store entry or manufacturer page carrying the foreign-language policy)-4
- Replacement cleaning pads only as proprietary original parts and at prices reaching a substantial share of the device price — evidenced by documented user/review criticism about restocking-3
- Documented clearly above approx. 75 dB(A) in normal operation (measurement in a review or manufacturer figure)-3
