Our verdict on each
AIRROBO
AIRROBO suits buyers who want a lidar-equipped robot vacuum with a self emptying dock at a modest flagship price, and it is the pick for anyone in the US or Canada. Its suction figure sits below the 11,500 Pa typical of this category.
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.

Pros and cons
AIRROBO
Pros
- Flagship price $299 ranks 13 of 66 brands, so the top of the range stays affordable.
- Lidar is fitted, which matches 94.7% of the robot vacuum brands listed.
- The range pairs a self empty dock with 10,000 Pa of suction.
Cons
- Suction of 10,000 Pa places AIRROBO at 30 of 46, below the 11,500 Pa seen across the category.
- Warranty lasts 1 year, which is short for a machine with a dock.
- Markets are limited to US and CA, so buyers elsewhere face a harder buy.
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.
Who each suits
AIRROBO
Who it suits
- Homeowners in US and CA who want a self emptying dock at a mid range price
- Buyers who value lidar navigation over raw suction figures
- People keeping spares on hand, since there is a spare parts shop
Who should look elsewhere
- Shoppers wanting the strongest suction in the category, where a higher ranked brand fits better
- Anyone outside US and CA who needs local support and returns
- Households that want sticks or uprights alongside a robot, where Philips or Ewbank cover more types
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.

Questions about each
AIRROBO
How much does the AIRROBO range cost?+
The flagship model in the range is priced at $299, which sits well below the €1,311.06 top of the category. AIRROBO covers robot vacuum, and the models listed are M2, Q20+, L60+. The range is a one-off hardware purchase, so there is no ongoing fee listed for using the machine or its app.
How strong is the suction on AIRROBO robot vacuums?+
The flagship robot is rated at 10,000 Pa, which places AIRROBO at 30 of 46 brands on that measure. The category median is 11,500 Pa, so you are buying a mid ranking figure rather than a headline one. If suction on carpet matters most to you, a higher ranked brand is worth a look.
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.
