Our verdict on each
Cowsar
Cowsar suits buyers in the US who want a full coffee setup, from a drip pot to a grinder-equipped espresso machine, at value prices. Entry sits at $79.99 and the flagship at $569.99, machines are bought outright with no renewal, and cover runs 1 year.
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
Cowsar
Pros
- A single brand covers the full set: espresso, bean to cup and drip espresso, bean-to-cup and drip, so the kitchen is not tied to capsules.
- A built in grinder on the espresso side, with auto frother milk handling on the 20 bar super fully automatic machine.
- Entry cost of $79.99 puts Cowsar among the cheaper brands in the coffee machine field, and support runs on email, phone and help centre.
Cons
- There is no spare parts shop, so wear parts and consumables have to come from general sellers rather than the brand.
- Warranty cover of 1 year is short for a machine bought outright and kept for years.
- Shipping covers the US market, so buyers elsewhere cannot be served by the listed delivery.
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
Cowsar
Who it suits
- Households that want a single brand across the kitchen, from a drip pot at $79.99 to an espresso machine.
- Sellers who want a $569.99 flagship espresso with a built in grinder and auto frother milk handling in the same catalogue.
- New espresso buyers who prefer the none pod setup and the flexibility that comes with ground coffee.
Who should look elsewhere
- Anyone outside the US market, since the listed shipping policy does not extend beyond the US.
- Readers who want a spare parts shop, which Cowsar does not have.
- Shoppers who would rather have longer cover and a wider service footprint from GASTROBACK or Philips.
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
Cowsar
What does a Cowsar coffee machine cost?+
The cheapest machine in the coffee range is $79.99, and the top of the range is the $569.99 flagship. That covers a personal single serve maker, a semi-automatic espresso machine with a built in grinder, a super fully automatic machine with grinder, and a drip coffee maker. Budget for a specific model rather than a range, since the spread is wide.
Does the espresso machine have a grinder and a milk system?+
A built in grinder is confirmed on the espresso models, so whole beans are ground inside the machine. Milk on the super fully automatic model is handled by an auto frother system, and pump pressure on the espresso range is 20 bar. That saves a separate countertop grinder, and milk drinks happen without a manual wand.
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.
