Best Mamibot Window Cleaners: Budget Option Tested

Not everyone needs a £350 window robot. If your windows are standard double-glazed, not excessively dirty, and you just want something that does a decent job for less than £200, the Mamibot iGLASSBOT W120-T exists. At £179, it is the cheapest window cleaning robot we would recommend. Below this price point, the suction and cleaning quality drop to unusable levels.

What We Like

Entry-level price at £179 makes window robot cleaning accessible for most budgets
Simple one-button operation with no app or WiFi setup required
Dual cleaning modes: auto for full window coverage, manual for spot cleaning
Anti-fall system with 3,000 Pa suction and UPS battery backup for safety

Watch Out For

Cleaning results are noticeably inferior to HOBOT and Ecovacs on dried-on grime
Single microfibre pad rather than dual spinning pads means slower coverage
Edge detection is less precise, often leaving 2 to 3 cm uncleaned around frames

Daniel Parks's Verdict

The Mamibot W120-T is the cheapest window cleaning robot worth buying. At £179, it handles lightly soiled windows acceptably but struggles with dried-on grime and precise edge cleaning. Buy it if budget is your primary concern. For genuinely clean glass, spend the extra £70 on the HOBOT 388.

Budget vs Mid-Range: Is £70 Extra Worth It?

Mamibot W120-T (£179) vs HOBOT 388 (£249)

Cleaning quality: HOBOT 388 wins. Dual spinning pads vs single microfibre pad. Noticeably better on dried grime.

Edge coverage: HOBOT 388 wins. Leaves 8 mm uncleaned vs Mamibot 20-30 mm. Visible difference on framed windows.

Suction: Mamibot wins slightly. 3,000 Pa vs 2,800 Pa. Not perceptible in daily use.

Weight: HOBOT 388 wins. 0.98 kg vs 1.1 kg. Both are light enough for easy handling.

Our take: The HOBOT 388 is worth the extra £70. The cleaning quality difference is visible in daily use, especially around edges and on windows that have not been cleaned for a month or more.

Frequently Asked Questions

Q Is Mamibot any good?

Mamibot delivers acceptable results for the price. The W120-T handles lightly soiled windows well but struggles with dried grime and precise edge cleaning. If your budget is firmly under £200, it is the best option. For £70 more, the HOBOT 388 is a significant upgrade.

Q Where is Mamibot from?

Mamibot is a Chinese robotics company founded in 2015. They manufacture robot vacuums and window cleaning robots for the budget segment. Products are sold on Amazon UK with 1-year manufacturer warranty and UK-based customer service via their Amazon seller account.

Q Does the Mamibot W120-T have auto-spray?

No. The W120-T requires manual pre-wetting of the cleaning pads or glass surface before use. Spray a window cleaning solution onto the glass, attach the robot, and press start. This adds 1 to 2 minutes of setup per window compared to auto-spray models.

Q Is the Mamibot safe on windows?

Yes. The W120-T has 3,000 Pa suction and a 15-minute UPS battery backup. It also includes a safety cord that clips to the window frame. We tested it for 4 months without any falls or detachment incidents on standard UK double-glazed windows.
