Clean­ing win­dows is not the most pleas­ant activ­i­ty. It, more­over, can be very dan­ger­ous if it is pro­duced on the upper floors of build­ings or from lad­ders near high shop win­dows. But tech­no­log­i­cal progress helps to facil­i­tate and secure this work.

Fol­low­ing robot vac­u­um clean­ers, win­dow clean­ing robots appeared. They are oval, round or square. The square shape of the body of the new house­hold appli­ance turned out to be opti­mal: thanks to it, it is pos­si­ble to clean the max­i­mum pos­si­ble glass area. Today, square win­dow clean­ing robots are steadi­ly gain­ing pop­u­lar­i­ty. The edi­tors of the KP have researched offers on the mar­ket for such gad­gets and offer their analy­sis for the judg­ment of read­ers.

Top 9 best square window cleaning robots in 2022 according to KP

1. Bist Win A100

The robot is designed to clean glass, mir­rors, tiled walls. Built-in sen­sors help deter­mine the dis­tance to obsta­cles and the bound­aries of the area to be cleaned. The nav­i­ga­tion sys­tem guides the move­ments with­out leav­ing a sin­gle gap. Struc­tural­ly, the gad­get con­sists of two blocks with noz­zles made of spe­cial mate­ri­als. A fiber noz­zle around the perime­ter of the device to col­lect all dirt and elim­i­nate traces of clean­ing agents.

After this treat­ment, the sur­face shines with clean­li­ness. A strong sur­face attach­ment is pro­vid­ed by a pow­er­ful vac­u­um pump. Even if the pow­er cable from the 220 V house­hold net­work is dis­con­nect­ed dur­ing glass wash­ing, the pump will con­tin­ue to work for anoth­er 30 min­utes thanks to the built-in bat­tery. At the same time, the robot will beep loud­ly to indi­cate a mal­func­tion.

Win­dow clean­ing robots

They do an excel­lent job not only with glass, but also with tiles, as well as smooth wood.

2. Xiaomi HUTT W66

The unit is equipped with an intel­li­gent con­trol sys­tem with laser sen­sors and an algo­rithm for cal­cu­lat­ing the opti­mal wash­ing route. Thanks to this, the robot is able to clean small win­dows from 350x350 mm in size or panoram­ic win­dows of high-rise build­ings. The only lim­i­ta­tion is the length of the safe­ty cord con­nect­ed to the 220 V house­hold pow­er cord.

If the pow­er is turned off, the vac­u­um pump will con­tin­ue to work for anoth­er 20 min­utes thanks to the built-in lithi­um-ion bat­tery. At the same time, an alarm will sound. The gad­get is equipped with a capac­i­ty of 1550 ml for water or deter­gent. It is sup­plied to 10 noz­zles under the pres­sure of a spe­cial pump.

3. HOBOT 298 Ultrasonic

The unit is held on a ver­ti­cal sur­face by a vac­u­um pump. Built-in pro­grams auto­mat­i­cal­ly deter­mine the bound­aries of the sur­face to be cleaned, con­trol the sides and cor­ners. Clean­ing agent or water is poured into a remov­able tank and sprayed with an ultra­son­ic noz­zle. Clean­ing wipes are made of microfiber fab­ric with a spe­cial pile struc­ture.

After wash­ing, it is com­plete­ly cleaned, restored and the nap­kin is ready for use again. The robot is able to clean glass of any thick­ness, dou­ble-glazed win­dows, panoram­ic win­dows of any height and shop win­dows. When wash­ing, the unit moves first hor­i­zon­tal­ly and then ver­ti­cal­ly, wash­ing the win­dow clean.

4. Kitfort KT-564

The device wash­es glass from the inside and out­side and walls with tiles. The vac­u­um required for suc­tion to a ver­ti­cal sur­face is cre­at­ed by a pow­er­ful fan. Rub­ber­ized wheels are used for move­ment. A clean­ing cloth moist­ened with wash­ing liq­uid is attached to the bot­tom.

Pow­er is sup­plied via a 5 m cable; in case of a pow­er out­age, a built-in bat­tery is pro­vid­ed that will keep the robot on the ver­ti­cal sur­face of the win­dow for 15 min­utes. Ball sen­sors are installed at the cor­ners of the case, thanks to which the robot finds the edges of the win­dow. It comes with a remote con­trol and can be con­trolled via an app on your smart­phone.

5. Ecovacs Winbot W836G

The device with an intel­li­gent con­trol and safe­ty sys­tem is equipped with a pow­er­ful vac­u­um pump, which ensures reli­able suc­tion to the glass. Posi­tion sen­sors are built into the bumper along the perime­ter of the body and accu­rate­ly deter­mine the bound­aries of any win­dow, includ­ing those with­out frames.

The robot car­ries out wash­ing in four stages. The glass is first moist­ened, then dried dirt is scraped off, the sur­face is wiped with a microfiber cloth and final­ly pol­ished. In the deep clean­ing mode, each sec­tion of the win­dow is passed at least four times. The built-in bat­tery will sup­port the oper­a­tion of the pump for 15 min­utes, keep­ing the robot on a ver­ti­cal sur­face when the 220 V mains volt­age fails.

6. dBot W200

Rotat­ing discs with microfiber cloths imi­tate the move­ments of human hands. Thanks to this, the robot does an excel­lent job of clean­ing even heav­i­ly soiled win­dows. The main advan­tage of this device is the Jet­Stream ultra­son­ic liq­uid atom­iza­tion sys­tem. The 50 ml capac­i­ty of the deter­gent is suf­fi­cient for clean­ing large glass­es, because the liq­uid is applied by spray­ing using ultra­sound.

Work­ing speed 1 m/min. Pow­ered by a 220 V house­hold mains, in case of a pow­er out­age, a built-in bat­tery is pro­vid­ed that keeps the pump run­ning for almost 30 min­utes. The device is con­trolled remote­ly using a remote con­trol.

How to choose a window cleaning robot

There are mag­net­ic and vac­u­um mod­els of win­dow clean­ing robots on the mar­ket today.

The mag­nets are made up of two parts. Each part is installed on both sides of the glass and is mag­ne­tized to each oth­er. Accord­ing­ly, with the help of such a robot it is impos­si­ble to clean mir­rors and tiled walls — it sim­ply can­not be fixed. Also, mag­net­ic wash­ers have lim­i­ta­tions on the thick­ness of the glaz­ing: before buy­ing, it is impor­tant to make sure that they are suit­able for your dou­ble-glazed win­dow.

The vac­u­um ones are held on the glass with a vac­u­um pump. They are more ver­sa­tile: suit­able for mir­rors and walls. And there are no restric­tions on the thick­ness of the dou­ble-glazed win­dow.

As a result, due to their advan­tages, vac­u­um mod­els almost com­plete­ly replaced mag­net­ic mod­els from sale. We rec­om­mend choos­ing a vac­u­um win­dow clean­er.
