Clariva Ultra (window-cleaning robot with dual spray): our review
Brand: ClarivaOur methodology
An overall score and radar chart require at least three verified comparable criteria.
Our full methodology
Scores calculated by comparing verified specifications across our catalogue. No hands-on testing. Comparison of documented models, not an exhaustive market survey. n is the number of models compared for each criterion. No hands-on testing.

The short versionThe Clariva Ultra offers useful features for frameless windows, but its performance remains insufficiently documented. It requires mains power during cleaning. We recommend checking compatibility with your glazing and the cable's reach before buying.

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.
Equipment: 7.2/10
Clariva Ultra scores 7.2/10 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 18 out of 27.
| Shared baseline: last place in the ranking | 6.5 |
|---|---|
| 4 features found out of 17 tracked: 3 perform worse, 17 perform better, 7 are tied (including this model), among the 27 catalogue models with this specification verified | +0.7 |
| Equipment score | 7.2/10 |
Calculation: (3 + 7 ÷ 2) ÷ 27 = 24.07% of the ranking; 6.5 + 24.07% × 3.1 = 7.2/10, rounded to one decimal place.
Recorded features: Spraying (Dual spray), Control (Remote control), Safety features (UPS backup battery), Cleaning modes (Deep cleaning).
The retailer does not specify: Compatible surfaces, Indoor / outdoor cleaning. These features are not counted.
The value for “Suction pressure” listed in the specifications (Not disclosed) is not confirmed by any verified source: this criterion is not scored and is excluded from the overall score.
The retailer does not specify “Water tank capacity”: this criterion earns no points and is excluded from the overall score.
The retailer does not specify “Backup battery holding time”: this criterion earns no points and is excluded from the overall score.
Who is this setup suitable for?
You want to automate cleaning your frameless windows and have a nearby power socket. You prefer remote control operation and are willing to set up the power connection before each use. This model could make your shortlist, provided you confirm compatibility with your specific glazing and the reach needed to access it.
Looking to automate cleaning your frameless windows? The Clariva Ultra combines dual spray, remote control operation and a deep cleaning mode. Our analysis covers the documented specifications, which outline its features but cannot confirm how well it will clean your windows.
1What do the Clariva Ultra's dual spray and deep cleaning mode offer?
+
The Clariva Ultra combines dual spray with a mode described as “deep cleaning”. These features describe what the device offers, but they are not enough to establish its cleaning effectiveness. Dual spray describes the liquid dispensing system; it proves neither even coverage nor a streak-free finish. Likewise, the mode's name does not specify the movements involved or the number of passes.
A remote control is also mentioned for operating the device. The available information does not specify which controls it provides. Assessing the likely results would require, above all, a description of the scrubbing system and documented cleaning observations. We therefore acknowledge the stated functions without crediting them with performance improvements that the supplied information does not demonstrate.
2Using the mains-powered Clariva Ultra on frameless windows requires preparation
+
Cleaning requires mains power, so you need an accessible power supply during use. The operating range is not specified, making it impossible to check whether the setup will suit your windows furthest from a socket. This is a practical point to clarify before ordering, especially if you intend to move the device between several windows.
The UPS backup battery is a safety feature and should not be confused with a battery for cordless cleaning. How long it can keep the device attached is not specified, so no protection time during a power cut can be stated. Finally, compatibility with frameless windows is explicitly indicated. However, this does not imply compatibility with all glazing, coatings or outdoor applications. Check that your setup is among the approved uses.
3Which alternatives should you compare with the Clariva Ultra?
+
The Clariva Ultra should be compared using criteria that make a real difference in use: glazing compatibility, cable reach, safety features and how it cleans. However, the supplied information includes no verified competitor specifications. It therefore does not support a reliable comparison using figures for named alternatives or a claim that this model offers more features at an equivalent price.
To distinguish between options, look for specifications that cover these details as well as the device's dimensions and weight. More complete documentation makes checks before purchase easier, without itself proving better cleaning quality. These details alone are not enough to establish good value for money.
Our final verdict on Clariva Ultra
The Clariva Ultra is worth considering if you want a device for frameless windows and can provide a nearby power supply. Its stated functions outline its features, but the available documentation leaves several operating requirements to be checked.
Worth noting
The main confirmed constraint is the need for mains power during cleaning. This model therefore does not meet a need for cordless cleaning, and the backup battery does not change that requirement. The operating range and how long the backup battery can keep the device attached are not specified.
Our verdict:
Our assessment remains cautious because there is insufficient evidence to judge cleaning effectiveness and ease of setup. The Clariva Ultra is an option to consider, but the available information does not justify a firm recommendation.

Frequently asked questions
Can the Clariva Ultra clean without being plugged in?
Mains power is the stated power source during cleaning. The battery mentioned is a UPS backup battery, not a power source for cordless cleaning.
Is it compatible with frameless windows?
Yes, this compatibility is explicitly listed in the supplied specifications. However, this does not confirm compatibility with every type of glazing or coating. Check the conditions of use for your windows.
How do you control the Clariva Ultra?
The specifications list a remote control. This is the control method confirmed by the available data.
Does dual spraying guarantee streak-free cleaning?
No, this feature describes the spraying equipment and does not prove cleaning results. The available information does not confirm streak-free cleaning.
What does deep cleaning mode mean?
This mode is explicitly listed for this model. Its name alone does not establish that it removes ingrained dirt or makes additional passes.
