7 mistakes to avoid before buying a robot vacuum
Buy a robot vacuum with no regrets: the 7 most common mistakes and how to avoid them.
Most bad purchases come from the same mistakes, repeated by thousands of buyers. Here are the 7 most common — and how to avoid them easily.
Mistake #1: buying the cheapest without thinking about use
The lowest price is tempting, but a model that doesn't fit your needs will need replacing soon. Think usage first, price second.
Mistake #2: following the most promoted product
Sponsored products are not necessarily the best. Always cross-check several independent sources before deciding.
Mistake #3: ignoring recent negative reviews
1-2 star reviews from the last few months reveal manufacturing flaws and reliability issues. Don't dismiss them.
Mistake #4: forgetting consumables and accessories
Cartridges, filters, wear parts: recurring costs can double the real price. Calculate them before buying.
Mistake #5: not checking compatibility
Dimensions, plugs, apps, ecosystem: one missed detail can make the device unusable at home. Check before checkout.
Mistake #6: rushing on a flash sale
A discount is only a deal if the product already suited you at full price. Compare the real market price first.
Mistake #7: neglecting warranty and support
Without a clear warranty and reachable support, the cheapest can become the most expensive. Warranty is part of the product.
