The short version

Remote control gives the CL-1 a clear appeal, but the finish remains a question

The CL-1 combines remote operation with mains power and a UPS backup battery. That gives it a straightforward operating arrangement for accessible windows. We would keep expectations measured because those features say more about running the robot than removing stubborn dirt.

Verdict

7.1/10

Our verdict on the CL-1

Evening sunlight is a demanding houseguest: every smear gets noticed. We like the CL-1's straightforward remote operation. The setup makes sense for accessible windows, but the available specifications do not establish how well it removes dirt or what finish it leaves.

Our verdict: We would put it on the shortlist for buyers comfortable handling it between panes. For a longer backup duration, the Lubluelu CHYW201 is better suited to that priority.

Worth noting What holds us back is the shorter attachment reserve during an outage. Avoid it if a longer response window is central to your choice.

Who it's for

Could the CL-1 fit your circuit of living room windows?

  • Households with accessible windows and nearby outlets
  • Buyers who prefer remote control
  • People comfortable carrying and positioning the robot

This model is worth considering if you prefer remote control and can comfortably handle placement on your living room windows. Think of a room where you can move from pane to pane without stretching over furniture. The appeal is help with the chore, provided you are comfortable remaining involved throughout it.

Less suitable if

Skip it if you need cleaning away from an outlet or struggle to lift equipment onto the intended glass. A remote control does not remove the physical work of placement and retrieval, especially when reaching above shoulder height.

Our scores explained

Every model on the site is scored on the same criteria, using the same scale: its position among models with verified data for that specification. Last place earns 6.5, first place 9.6, and the rest are scored in proportion to their rank. Here is how this model's scores are calculated.

Two model counts: the rank and average include product pages on this site scored for the criterion; the calculation compares the model with all catalogue models whose specification is verified, with or without a product page. A score assigned at publication may remain without a verified specification, so the first count can sometimes be higher.

Backup battery holding time: 7.5/10

Chovery CL-1 scores 7.5/10 on this criterion. Across the 16 product pages on the site with a score for this criterion, the average is 8.1: below average, Rank 7 out of 16.

Backup battery holding time: 20 min ; 0 perform worse, 6 perform better, 10 are tied (including this model), among the 16 catalogue models with this specification verified+1
Backup battery holding time score7.5/10

Calculation: (0 + 10 ÷ 2) ÷ 16 = 31.25% of the ranking; 6.5 + 31.25% × 3.1 = 7.5/10, rounded to one decimal place.

Equipment: 6.7/10

Chovery CL-1 scores 6.7/10 on this criterion. Across the 27 product pages on the site with a score for this criterion, the average is 8.1: below average, Rank 25 out of 27.

Our full methodology

Detailed analysis

The dog has added another nose print to the backyard glass, and the higher panes still carry winter's dull film. The Chovery CL-1 offers remote control, mains-powered operation, and a UPS backup battery for a chore you would happily hand over. Those features explain how it fits into the household routine. How well it clears that view is the bigger buying question.

The CL-1 window cleaning robot needs an outlet for its 80 W supply

The sunroom looks inviting until afternoon light picks out the film on its glass panels. That is the sort of recurring chore that makes this robot worth considering. Its electrical power is specified at 80 W, with an outlet required throughout cleaning. For your routine, the practical point is the connection: this electrical rating does not tell you how quickly the glass will be cleaned or how much dirt will come off.

The cord sets the boundaries. Before picturing yourself settling into a patio chair, consider where the connection will sit and how you will reach the robot afterward. Does your intended window have a practical power connection nearby? We would settle that question before getting attached to the idea of automation. A robot can join the household chores without getting to rewrite the floor plan.

What does the CL-1's 20 min backup mean for an upstairs window?

A power interruption becomes a different proposition when the machine is outside an upstairs window. The UPS backup battery has an advertised holding time of 20 min, a typical backup duration intended to keep the robot attached while you respond. Cleaning still requires mains power. Treat the reserve as time to retrieve the machine, never permission to continue the job without an electrical connection or a guarantee against a fall.

Would you be able to get back to the glass promptly? Manufacturers' manuals instruct users to secure a safety tether to a fixed anchor and remain nearby during cleaning, especially upstairs. Keep access clear before cleaning begins. The useful question is how you would bring the robot back inside if the power stopped halfway through the job.

Our Chovery CL-1 review puts its 0,95 kg weight and 13 cm height in context

At 0,95 kg, this robotic window cleaner gives you a concrete lifting figure to consider before planning a circuit of the living room windows. You still have to carry it, position it, and retrieve it. A manageable lift at waist level can become a less appealing task when the glass starts above your shoulder. Convenience includes the handoff between windows.

Its 13 cm height describes how far the body projects from the glass. Think about space around blinds and nearby obstructions, including room to grasp the machine comfortably. Remote control is the verified way to operate it, so you can keep commands close at hand once it is positioned. We like that straightforward arrangement, although the remote cannot take over carrying duties. The household still has an unpaid logistics department.

A longer backup duration could make the difference at your picture window

The Lubluelu CHYW201 is better suited to buyers who want a longer backup duration than the CL-1 offers. The Lubluelu CHYW201 has a higher backup battery holding time at 30 min, giving you extra response time during an outage. That difference matters when getting back to the intended window involves more than standing up from a nearby chair.

Picture the handoff between panes: you still have to lift the robot, place it on the glass, and bring it back within reach. That physical routine is worth weighing alongside remote operation. A room full of separate windows means repeating those movements, even when the wiping itself is the chore you want help with. Choose around the whole job. For this model, the practical setup is easier to judge than the cleaning outcome; a remote and backup battery cannot tell you what the evening sun will reveal on the glass.

Frequently asked questions

Your questions about the CL-1 before ordering

Can the CL-1 clean without being plugged in?

No. Cleaning requires mains power. The UPS backup battery is intended to keep the robot attached temporarily during a power interruption so you can retrieve it. It does not supply an unplugged cleaning session.

How do you control the CL-1?

Remote control is the verified control method. Keep the controller within comfortable reach, but remember that you still need to position the robot on the glass and retrieve it when the job ends or needs your attention.

What should you check before ordering this window cleaning robot?

Confirm warranty coverage, customer support, return terms, and replacement cloth availability with the retailer. Also confirm whether a safety tether and extension cord are included, so you know what equipment you will need before setting up.

Can you leave it working while you head elsewhere?

Stay nearby during cleaning. Manufacturers' manuals instruct users to attach a safety tether to a fixed anchor, especially for upstairs exterior windows. Keep access to the glass clear so you can respond promptly if power stops.
