Our verdict on each
Coolblue Belgium
Coolblue Belgium suits Belgian households that want one local shop for robot vacuums, air treatment and security cameras, with a 30-day returns window behind every purchase. It suits buyers who value breadth, local delivery and in-country support over a narrow range or a subscription-based plan.
Zelmer
Zelmer is a fair pick for Polish households who want plain cordless floor care at an entry price of PLN 349 and a flagship of PLN 1,199. It suits buyers who mop separately and empty the bin by hand, and less suits anyone chasing dock automation or Matter.

Pros and cons
Coolblue Belgium
Pros
- The camera listing covers recording to microSD card, a base station or a hard drive without a subscription, plus app live view and motion alerts, and local storage is offered.
- Support runs on email, chat and phone, and a spare parts shop keeps brushes, filters and mop pads orderable after purchase.
- Floor care spans robot vacuum, stick and handheld, so a robot vacuum can be bought alongside a stick or handheld vacuum in the same order.
Cons
- Floor care stops at robot vacuum, stick and handheld, so a buyer who wants an upright or wet-dry vacuum has to shop elsewhere.
- The app carries no energy reporting, so household energy use has to be measured elsewhere.
- A hub is required before bridges speak zigbee and wi fi, so smart home buyers pay for extra hardware before the first device goes in.
Zelmer
Pros
- The flagship cordless stick runs for 55 minutes on a charge, and the Piotr cordless model holds 800 ml of debris between empties.
- A 2 years warranty covers the flagship cordless vacuum, giving buyers a defined period for repairs and replacements.
- A spare parts shop is available, so filters, brushes and bins can be ordered from the brand for the working life of a machine.
Cons
- Self empty dock is not offered in the vacuum range, so the bin is still emptied by hand after each use.
- Lidar is not used on the cordless sticks, which leaves mapping and route detail basic next to robot-first ranges.
- Matter is not supported, so the vacuums cannot join a Matter setup alongside other connected devices.
Who each suits
Coolblue Belgium
Who it suits
- Belgian households replacing a vacuum or a purifier who want delivery, returns and support handled by one local operation.
- Camera buyers who want recording to microSD card, a base station or a hard drive without a subscription.
- Shoppers whose floor care shortlist is robot vacuum, stick or handheld, the types this range covers.
Who should look elsewhere
- Buyers who want upright or wet-dry vacuums, since floor care here covers robot vacuum, stick and handheld only.
- Shoppers outside Belgium, since Coolblue Belgium delivers only to Belgian addresses.
Zelmer
Who it suits
- Polish households buying a cordless stick or upright who expect phone and email support plus a spare parts shop after the sale.
- Shoppers who mop with a separate appliance, since mopping is listed as none on the cordless line.
- Homes that want long runtime per charge, given the 55-minute rating on the flagship cordless stick.
Who should look elsewhere
- Readers who want a robot vacuum in the same basket, since Hoover covers robot vacuum, stick and upright while the Zelmer range has no robot type.
- Buyers building a one-brand floor-care set that includes a robot, since Daewoo Electricals covers robot vacuum, stick and upright including that type.
- Shoppers who want mopping built into the cordless machine, since Zelmer lists none for mopping and Ewbank at robot vacuum, stick and upright is the nearer match for wet-dry work.

Questions about each
Coolblue Belgium
What does the cheapest robot vacuum cost at Coolblue Belgium?+
The lowest robot vacuum price is €199, and the top of the range is €1,199. Reference models are named at each end of the list, so the gap between the two prices buys hardware rather than a subscription. Neither figure renews after the purchase.
Is the flagship robot vacuum worth more than the entry model?+
The step up from entry at €199 buys a self empty dock, Lidar mapping and a mop pad that lifts 10.5 mm, on a machine that pulls 42,000 Pa and stands 8.9 cm tall. Buyers who already know they want a dock and a mop lift should go straight to the flagship.
Zelmer
How much does a Zelmer cordless vacuum cost?+
The cordless vacuum range has an entry price of PLN 349, and the flagship cordless stick is listed at PLN 1,199. Those figures mark the low and high ends of what the brand asks for a vacuum. Both are single product prices, so a shopper is weighing the purchase cost rather than a plan that renews.
Which cordless models does Zelmer list?+
The cordless range names ZVC351 Antek, ZSVC912BF PET Pawel, ZSVC510D Piotr as its reference models, covering an upright, a stick aimed at pet hair and a compact stick for smaller spaces. The list is short, so narrowing the choice is easy. Buyers should match the model to floor type and to pet hair rather than to runtime alone, since runtimes differ across the line.
