Our verdict on each
Kärcher
Kärcher suits households who want a robot vacuum and a stick machine from the same maker, with the self empty dock and lidar both listed. Suction of 15,000 Pa sits level with the site median, so buyers chasing raw power have wider options, while GB shoppers can reach email, phone and help centre.
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
Kärcher
Pros
- Self empty dock and lidar are both listed, while 15.8% of listings on the site have no self empty dock.
- A spare parts shop is listed, and only 3.8% of listings lack one, so wear parts can be ordered directly.
- The warranty runs 2 years, a useful length of cover on a machine that runs most days in a busy home.
Cons
- Suction tops out at 15,000 Pa, level with the site median 15,000 Pa, so it does not lead on raw power.
- Mopping is limited to a roller system only, with no pad or spinning alternative listed.
- The range skips upright and handheld formats that both Daewoo Electricals and Ewbank list in robot vacuum, stick and upright and robot vacuum, stick and upright.
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
Kärcher
Who it suits
- Households that want the robot, the wet-dry and the stick machine from the same brand.
- Buyers who weigh ownership details heavily: 2 years of cover, a spare parts shop and email, phone and help centre.
- Busy homes that want lidar mapping and a self empty dock rather than the highest suction figure.
Who should look elsewhere
- Anyone who wants upright and handheld formats alongside the robot should start with Daewoo Electricals, whose robot vacuum, stick and upright covers more formats than this range.
- Shoppers who do not want a stick machine in the same range may prefer Philips, which lists robot vacuum and wet dry.
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
Kärcher
How much do Kärcher's floor care machines cost?+
Budget from the category spread rather than the brand name. Robot vacuum entry prices in this category centre on €145.84 and flagship models sit at €719, while cordless entry prices sit at €99.99.
Does the robot empty its own dock?+
Yes, a self empty dock is listed, so the machine empties its bin between runs without you handling it. Lidar is also listed for mapping, and the models named in RVF 7 Comfort, RVM 4 Comfort, RVC 3 Comfort, RCF 3 cover the robot and the stick machine.
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.
