What to check before buying
Owners prioritizing installation simplicity and mapping without a boundary wire or external antenna. Start with the job the machine must do in your own space, then compare the features that can change that outcome. A specification sheet is useful for narrowing a shortlist; it does not replace a demonstration of the difficult part of your cleaning routine.
Confirm the local area rating and cutting-height range; do not import an EU capacity label into a US offer.
Versions and market differences
This overview uses the US product page. The linked EU manual is for reference and must be matched to the unit’s region and model code before applying dimensions or operating limits.
Maintenance and ownership
Plan access to blades, wheels and the LiDAR window. Ask the local seller about repairs and any optional 4G module or subscription; connected features should be included in the ownership budget.
Ask the seller to identify the local warranty provider, exclusions, repair location and spare-parts lead time in writing. Warranty terms and bundled accessories belong to the specific market and seller; this profile does not promise universal coverage.
