Price is the widest gap in the category
Robot vacuum prices spread much further apart than most appliances you would put in the same trolley. Entry model prices across the category span €31.37 to €1,311.06, and flagship model prices span €114 to €2,698.95. That spread is your first filter, because a flagship machine normally adds hardware the entry model skips rather than a better finish on the same specification.
A price tells you less on its own than the specification behind it, so read the two together. Use the robot vacuum rankings to see which models sit at each end of that range, then narrow to two or three before you read anything else.
Bin size decides how often you empty it
Buyers usually weigh suction first and think about emptying later, yet the bin is the part you touch on every single run. Daewoo Electricals lists a 200 bin, while Ewbank lists 400. More capacity means fewer trips to the kitchen bin, which matters most in homes with pets, a lot of carpet or several rooms per clean.
Size the bin against the emptying routine rather than treating it as a spec to win. Where a dock empties the machine for you, the figure matters much less, and Daewoo Electricals offers a self empty dock. The Daewoo Electricals review and the Ewbank review show how each of these two floorcare lines is put together.
Height is the figure that decides what a machine can reach
Robot vacuums disappoint in a predictable way: they stop just short of the space you most wanted covered. Height is what settles that, and the two brands here differ. Daewoo Electricals gives 7.5 for its SmartNav robot vacuum, while Ewbank gives 9.5 for its auto empty station model.
Measure the tightest gap you want cleaned first, including the space beside a bed base and under a low sofa, then compare it with the height figure. Thinner is more useful, and a machine that clears your lowest furniture is worth more than one with a longer spec sheet.
Suction and mopping: read them as a pair
Suction is the headline number and the spread across the category is enormous, with listed maximum suction ranging from 1,800 to 40,000. Daewoo Electricals quotes 4,000 for its SmartNav model. A spread that wide means the headline figure ranks poorly on its own, because floor type and brush design change results far more than the top of the range does.
On the mopping side these two brands sit level: Daewoo Electricals uses a pad and Ewbank also lists a pad. Mop lift is the feature that separates them, and where it appears in the category the lift ranges from 8 to 15.24, so check which models on your shortlist include it.
Navigation is where the price spread starts to make sense
Lidar and obstacle avoidance explain most of the gap between an entry machine and a flagship one. Ewbank's auto empty station robot vacuum has Lidar, while Daewoo Electricals' SmartNav model does not and records obstacle avoidance as none. Without mapping hardware a machine tends to bump into furniture and negotiate obstacles less efficiently, which shows up as longer cleaning times and untidy edges.
Mapping suits larger homes, pets and rooms with cables or clutter on the floor. If that describes your household, this is the feature to spend on, and it is worth settling before you compare suction figures.
Runtime and the area you can clean per run
Daewoo Electricals lists a runtime of 130 for its SmartNav robot vacuum. Runtime sets the area covered in one pass, so weigh it against your floor area before you buy: a machine that needs a mid clean charge will not finish a large home in a single run, however strong its suction.
Ask the retailer what happens at the end of a run and whether the robot returns to its dock on its own, and whether it will avoid a room you have blocked off. Those answers decide whether the runtime figure matters to you at all.
Support, warranty and who stands behind it
After the specification, the practical question is who handles a jammed dock. Daewoo Electricals offers support through email, chat and help centre and a 3 years warranty. It does not run a spare parts shop, so brushes, filters and bins come through the usual retailers, and its legal entity is Eurosonic Group Limited, the name that appears behind the brand on paperwork.
Both are British brands: Daewoo Electricals is headquartered in GB and sells in GB, while Ewbank is based in GB and was founded in 1864. A long trading history and a listed warranty tell you how long the brand expects the machine to last, which is a fair proxy for build quality on parts you cannot see.
The order to compare in
Work through the figures in this order: price, bin size and emptying, height against your furniture, navigation hardware, then suction and mopping, then support and warranty. Price first tells you the tier, height tells you what the machine can reach, navigation tells you how it behaves around obstacles, and the rest fine tunes the choice.
Once you have a shortlist, check each machine against the robot vacuum rankings and read the brand reviews for Daewoo Electricals and Ewbank to see how the whole floorcare line performs, not just the single model you are considering.
